How Contactless Monitoring Technology is Transforming Veterinary Care 

Veterinary medicine is embracing innovation at an unprecedented pace, and one of the most transformative technologies to emerge is contactless vital signs monitoring. Traditionally, measuring heart rate, respiratory rate, and temperature requires physical contact—often causing stress for pets and consuming valuable time for veterinary teams. Contactless monitoring changes this dynamic by enabling accurate, noninvasive measurement of vital signs without touching the animal. This advancement is revolutionizing patient care, improving efficiency, and enhancing the overall veterinary experience. 

 

The stress-reduction benefits of contactless monitoring extend across all companion animal species. Cats, which often experience significant stress from restraint and handling in clinical settings, benefit particularly from monitoring methods that don’t require direct contact. Exotic pets—including rabbits, birds, and reptiles—can be monitored more safely without the risks associated with manual restraint of fragile or easily stressed species. Even cooperative canine patients benefit from the streamlined workflow that contactless systems provide during routine wellness examinations.

What is Contactless Monitoring for Veterinary Patients?

Contactless monitoring uses advanced sensors and imaging technologies to measure physiological parameters without direct physical interaction.  Methods include: 

  • Thermal imaging: Detect body temperature through heat signatures 
  • Radar and LiDAR sensors: Measure micromovements associated with breathing and heart rate 
  • Computer vision and AI: Analyze subtle changes in body posture, chest movement, and facial cues to interpret animal status 

 These contactless monitoring systems vary in complexity and application. Some platforms offer real-time continuous surveillance suitable for intensive care units and recovery areas, while others provide on-demand vital signs collection during routine examinations. The technology can be adapted to different clinical environments—from traditional exam rooms to isolation wards where minimizing staff entry is critical. As these systems become more sophisticated, they’re increasingly capable of monitoring multiple patients simultaneously, making them practical even for busy multi-doctor practices. 

Clinical Benefits of Contactless Monitoring in Veterinary Practice

Animals often experience stress during veterinary visits, which can skew vital signs and complicate diagnosis. Contactless monitoring helps address these challenges by: 

  • Reducing stress caused by restraint or invasive probes 
  • Improving accuracy by capturing data while patients remain calm 
  • Enhancing safety by minimizing the risk of injury to staff and patients 
  • Saving valuable time by streamlining clinical workflows 

This technology proves particularly valuable for feline patients, exotic species, and any animals that become aggressive or fearful when handled. Traditional vital signs collection often requires multiple staff members to restrain anxious patients, which can elevate heart rate and respiratory rate—the very parameters being measured. Contactless systems eliminate this paradox by allowing animals to remain in a relatively calm state during data collection. For veterinary technicians and assistants who face injury risk from fractious patients, contactless monitoring also represents a meaningful safety improvement that can reduce workplace injuries and associated costs. 

The benefits extend beyond the clinic, improving the overall experience for pet owners while supporting better patient outcomes, early detection of health concerns, and improved operational efficiency for veterinary teams. 

Practical Applications of Contactless Monitoring Technology

There are several clinical applications for contactless monitoring in veterinary settings. Postsurgical recovery and critical care patients, in particular, can benefit from more frequent or continuous vital signs monitoring without disruption. Isolation wards offer another valuable use case, with the potential to reduce staff exposure and lower PPE costs. Overnight monitoring—especially in rural or understaffed clinics—can be enhanced through imaging-based systems and smart device alerts that provide peace of mind and rapid response capabilities. 

In post-surgical settings, contactless monitoring technology allows veterinary teams to track recovery patterns without repeatedly disturbing anesthetized or painful patients. Animals recovering from procedures can rest undisturbed while staff receive continuous or interval updates on vital signs, enabling early detection of complications like hypothermia, respiratory depression, or emerging cardiovascular concerns. This hands-off approach is especially beneficial for orthopedic surgery patients where minimizing movement during initial recovery is critical. 

For isolation ward applications, the technology offers dual benefits: protecting staff from infectious disease exposure while ensuring patients receive adequate monitoring despite limited direct contact. During disease outbreaks or when managing highly contagious cases, contactless systems enable vital signs collection without the time, expense, and environmental impact of repeatedly donning and doffing protective equipment. Emergency and specialty hospitals managing infectious disease cases have found this capability particularly valuable for maintaining both biosecurity protocols and high standards of patient monitoring. 

Implementation Considerations for Veterinary Practices

While promising, contactless monitoring does come with practical considerations that veterinary practices should evaluate before implementation: 

  • Cost and accessibility: Advanced sensors may represent a significant initial investment. Practices need to assess how these systems will integrate with existing practice management software and medical records platforms, which may require additional technical infrastructure or IT support. 
  • Training requirements: Practices need to assess how these systems will integrate with existing practice management software and medical records platforms, which may require additional technical infrastructure or IT support. 
  • Environmental factors: Lighting conditions, patient movement, and positioning can impact readings. Certain patients may present additional challenges—heavily coated breeds, very small animals, or patients with specific coat colors can sometimes interfere with sensor readings. For these reasons, practices should maintain traditional monitoring capabilities as backup methods when contactless systems may not provide reliable data. 

The Future of Contactless Veterinary Monitoring Technology

Despite these challenges, contactless vital signs monitoring represents far more than convenience—it is a meaningful leap forward in veterinary care. By reducing stress, improving accuracy, and enabling proactive health management, this technology strengthens the human-animal bond and elevates the standard of care. As adoption continues to grow, veterinarians who embrace these tools will be well positioned to lead the future of compassionate, efficient, and cutting-edge medicine.

Series 3: Managing Bleeding & Preventing Enucleation Surgery Complications 

In Parts 1 and 2, we covered Dr. Broadwater’s revolutionary positioning and surgical techniques. This final installment focuses on the challenge that intimidates many veterinarians most: controlling orbital bleeding and preventing complications that bring patients back to surgery. 

The Orbital Bleeding Challenge

Orbital bleeding presents unique challenges during enucleation surgery that traditional hemostatic methods struggle to address effectively. 

Why Traditional Hemostatic Methods Fall Short

Electrocautery limitations: 

  • Can’t reach deep bleeding sites effectively 
  • Risk of thermal damage to surrounding tissues 
  • Difficult to maneuver in confined orbital space 

Standard hemostatic sponges: 

  • Don’t conform to irregular orbital anatomy 
  • Often too large for precise placement 
  • May not maintain contact with bleeding sites 

Multiple bleeding sites: 

  • Require repeated intervention attempts 
  • Delay surgery while addressing each location 
  • Can obscure visualization when multiple sites bleed simultaneously 

Advanced Hemostatic Control with Vetigel ® Hemostatic Gel

Dr. Broadwater describes Vetigel Hemostatic Gel as particularly valuable for orbital bleeding control, addressing the specific challenges that traditional methods can’t handle effectively. 

Superior Conformability for Orbital Anatomy

Plant-based gel design: 

  • Conforms to irregular bleeding sites deep in orbit 
  • Reaches locations traditional methods cannot access effectively 
  • Flows into crevices and around irregular surfaces 
  • Maintains contact even in difficult-to-reach areas 

Clinical advantage: The gel’s ability to conform means you can treat bleeding sites that would otherwise require extensive dissection to access with other methods. 

Mechanical Barrier Formation

Advanced hemostatic mechanism: 

  • Cross-linked structure creates immediate mechanical barrier 
  • Enhanced viscosity and cohesive strength adhere to bleeding tissues 
  • Doesn’t disturb natural fibrin clot formation – works with body’s natural processes 
  • Maintains barrier integrity even in wet surgical environment 

Dr. Broadwater’s observation: “The gel creates an immediate seal that stays in place, unlike other hemostatic agents that can wash away or lose effectiveness in a bloody field.” 

Bioabsorbable Design Eliminates Concerns

Complete dissolution: 

  • Completely dissolves within two weeks 
  • Eliminates long-term foreign body concerns 
  • No removal procedure required 
  • Reduces risk of chronic inflammatory reactions 

Clinical Application of Vetigel Hemostatic Gel

Application technique: 

  • Apply directly to deep orbital bleeding sites using included sterile cannula 
  • Use only amount needed – product is effective in small quantities 
  • Can be applied to multiple sites simultaneously 
  • Works immediately upon contact with bleeding tissue 

Strategic timing: Dr. Broadwater applies Vetigel hemostatic gel as soon as significant orbital bleeding is encountered, rather than struggling with traditional methods first. 

Hemostatic Management Strategy

First-line approaches include: 

Electrocautery for accessible sites: 

  • Effective for surface bleeding that can be directly visualized 
  • Use lower settings to minimize thermal damage 
  • Most effective for single, discrete bleeding points 

Pressure and time for minor bleeding: 

  • Often effective for smaller vessels 
  • Combined with patient positioning allows gravity assistance 
  • Requires patience but avoids unnecessary intervention

When to Advance to Vetigel Hemostatic Gel

Indicators for Vetigel hemostatic gel use: 

  • Persistent deep orbital bleeding uncontrolled by electrocautery 
  • Multiple bleeding sites requiring simultaneous treatment 
  • Bleeding in locations difficult to access with traditional methods 
  • Cases where continued bleeding significantly impairs visualization 

Application protocol: 

  1. Identify bleeding source as precisely as possible 
  2. Apply Vetigel hemostatic gel directly to bleeding site using sterile cannula 
  3. Allow 30-60 seconds for gel to take effect 
  4. Resume surgery once hemostasis achieved 
  5. No need to remove gel – it will dissolve naturally 

Alternative Hemostatic Options

Absorbable gelatin sponges: 

  • Less effective for deep orbital bleeding 
  • May be useful for surface bleeding 
  • Require precise placement and often multiple pieces 

Orbital implants: 

  • Dr. Broadwater discourages due to 2-3% rejection/infection risk 
  • Adds unnecessary complexity and potential complications 
  • Not recommended for routine enucleation 

Preventing Common Complications

Orbital cysts are a common side effect of eye removal. Primary causes of post-surgical cysts include: 

  • Retained conjunctival tissue with goblet cells – most common cause 
  • Incomplete third eyelid removal – must include gland 
  • Retained medial canthal caruncle – often overlooked during surgery 

Dr. Broadwater’s prevention strategy: “If it’s pigmented tissue, remove it.” This simple rule provides clear guidance for complete conjunctival removal and prevents the majority of cyst complications. 

Systematic approach: 

  • Remove all visible conjunctival tissue 
  • Pay special attention to medial canthal area 
  • Ensure complete third eyelid and gland removal 
  • Double-check for any remaining pigmented tissue before closure 

Chronic Draining Tracts

Common misconception: Many veterinarians treat draining tracts appearing months post-surgery with repeated antibiotic courses. 

Dr. Broadwater’s approach: These typically indicate retained material requiring surgical exploration rather than infection. Antibiotics rarely resolve the underlying problem. 

Typical causes of draining tracts: 

  • Retained conjunctival tissue creating continued secretion 
  • Foreign material (suture, debris) causing chronic irritation 
  • Incomplete medial canthal caruncle removal
  • Retained glandular tissue from incomplete third eyelid removal 

Management strategy: Surgical exploration and removal of retained material is usually required for definitive treatment. 

Excessive Post-Operative Bleeding Control

Normal expectations: 

  • Most orbital swelling resolves within 24-48 hours 
  • Conservative management usually sufficient 
  • Cold compresses and patient sedation for active animals 

Dr. Broadwater’s experience: “I rarely need to return to surgery for bleeding control when using proper hemostatic technique during the initial procedure.” 

Prevention through proper technique: 

  • Proactive hemostatic management during surgery 
  • Use of Vetigel hemostatic gel for persistent orbital bleeding 
  • Careful attention to complete muscle and tissue removal 
  • Proper closure technique 

Quick Reference: Complication Prevention Checklist

  Remove all pigmented conjunctival tissue systematically  
  Complete third eyelid removal including gland  
  Address medial canthal caruncle completely  
  Use Vetigel hemostatic gel for persistent orbital bleeding  
  Test 360-degree globe rotation before optic nerve transection  
  Inspect surgical site for retained tissue before closure  
  Apply appropriate closure technique for tissue layers 

Implementation Guidelines for Your Practice

Series 2: Essential Instruments & Enucleation Surgical Technique 

In Part 1, we covered Dr. Broadwater’s revolutionary dorsal positioning technique. Now discover the three specialized instruments that make enucleation surgery dramatically easier, plus his refined step-by-step surgical approach that consistently delivers 15-20 minute procedures. 

Essential Specialized Instruments for Eye Removal Surgery

Dr. Broadwater emphasizes that while general surgical instruments can complete an enucleation, these three specialized tools make the procedure significantly easier, safer, and faster. 

Enucleation Scissors - The Game Changer

Why they’re essential: 

  • Curved design follows orbital bone curvature – works with anatomy instead of against it 
  • Allows safe approach to optic nerve – reduces risk of excessive traction 
  • Critical for preventing contralateral optic nerve damage – curved approach minimizes pulling forces 
  • Especially important for cats and swollen glaucomatous eyes – tight spaces require precise instrument control 

Dr. Broadwater’s insight: “The curved design isn’t just convenient – it’s a safety feature. Straight scissors force you to pull harder on the globe to access the optic nerve, which can damage the opposite eye’s vision.” 

Stevens Tenotomy Scissors - Precision Dissection

Use these for all extraocular muscle dissection and fine tissue work around the globe. The narrow tips allow you to work in tight spaces without damaging adjacent structures. Key advantages: 

  • Narrow tips provide precision for delicate tissue work – essential for thin orbital tissues 
  • Enable controlled blunt dissection of extraocular muscles – reduces accidental tissue damage 
  • Superior to Mayo scissors for fine orbital work – size and design optimized for small spaces 

Bishop Harmon Forceps (8mm) - Gentle Tissue Handling

These forceps excel at grasping conjunctiva and other delicate orbital tissues without the excessive trauma that larger instruments can cause.

Design benefits:

  • Small rat-tooth design ideal for thin conjunctival tissue – provides secure grip without tearing
  • Less traumatic than standard Brown-Adson forceps – reduced tissue crushing 
  • Particularly valuable for smaller patients – appropriate scale for delicate work 

Step-by-Step Enucleation Surgery Technique

Dr. Broadwater’s modified subconjunctival approach incorporates key modifications that dramatically improve efficiency and outcomes.

Initial Exposure - Key Modifications

1.  Transect lateral canthus for improved exposure

  • Make clean incision through lateral canthal ligament 
  • Creates significantly wider surgical field 
  • Essential for comfortable instrument access 

2. Remove eyelids early in procedure (not at end as traditionally taught) 

  • Traditional teaching removes lids last – this is inefficient
  • Early removal provides immediate improved visualization 
  • Eliminates tissue that obscures the surgical field 

3.  Remove third eyelid completely, including gland, early in process 

  • Complete removal prevents future cyst formation 
  • Early timing improves access for subsequent steps 
  • Include the gland to ensure no retained secretory tissue 

Conjunctival Management Technique

Strategic incision placement: 

  • Begin conjunctival incision 5-6mm from limbus – provides tissue margin for manipulation 
  • Leave tissue rim for globe manipulation – creates “handle” for rotating the eye 
  • Systematically remove all pigmented conjunctival tissue – prevents future cyst complications 

Dr. Broadwater’s rule: “If it’s pigmented tissue, remove it.” This simple guideline prevents the majority of post-surgical complications. 

Extraocular Muscle Dissection Protocol

Systematic muscle identification and transection: 

  • Superior rectus – easiest to identify, start here 
  • Ventral rectus – follow inferior orbital rim 
  • Medial rectus – closest to nasal cavity 
  • Lateral rectus – toward temporal side 
  • Superior oblique – runs through trochlea 
  • Ventral oblique – smallest muscle, easy to miss 

Critical checkpoint: Test complete muscle release by rotating globe 360 degrees. If you feel resistance, identify and transect the remaining attachments. 

Instrument technique: Use Stevens tenotomy scissors for precise separation. The narrow tips allow you to dissect individual muscles without damaging adjacent structures. 

Optic Nerve Transection - The Critical Step

Safe approach technique: 

  • Use curved enucleation scissors following orbital curvature – natural anatomical approach 
  • Approach dorsally-laterally for optimal exposure – best visualization and control 
  • Minimize traction to protect contralateral optic nerve – excessive pulling can damage the opposite eye 

Key safety point: The optic nerves connect at the chiasm. Aggressive traction on one side can compromise vision in the opposite eye. The curved scissors reduce this risk significantly. 

Pain Management Protocol for Eye Removal Surgery

A comprehensive anesthetic approach includes pre-medication:

  • First choice: Fentanyl and midazolam 
  • Alternative: Buprenex and midazolam if fentanyl unavailable 
  • Provides excellent baseline analgesia and anxiolysis 

Induction and maintenance: 

  • Induction: Propofol for smooth, controlled induction
  • Maintenance: Isoflurane with fentanyl CRI for balanced anesthesia 

Retrobulbar Nerve Block Technique

Dr. Broadwater performs blocks on all appropriate cases using specific technique and dosing. 

Equipment: 1.5-inch, 22-gauge spinal needle 

Technique: 

  • Walk needle tip along orbital bone to stay away from globe 
  • Penetrate muscle cone for effective anesthesia
  • Inject slowly to avoid tissue damage 

Dosing protocols: 

  • Dogs/cats under 10kg: 0.5ml lidocaine + 0.5ml bupivacaine + 0.1ml epinephrine 
  • Dogs over 10kg: 1ml lidocaine + 1ml bupivacaine + 0.2ml epinephrine 

Important contraindications: Avoid retrobulbar blocks if infection or cancer present due to potential seeding risk. 

Surgical Timeline Results

Dr. Broadwater reports remarkable consistency in surgical times using this refined approach: 

  • Setup and positioning: 3-5 minutes 
  • Surgical procedure: 12-15 minutes 
  • Closure and cleanup: 3-5 minutes 
  • Total time: 15-20 minutes consistently 

Efficiency Factors

The time savings come from: 

  • Optimal positioning reducing fumbling with instruments
  • Specialized instruments designed for the specific tasks 
  • Systematic approach eliminating wasted motion 
  • Early tissue removal providing immediate better visualization 

Implementation Strategy

While specialized instruments require upfront investment, the time savings and improved outcomes justify the cost for practices performing regular enucleations. 

Learning curve: Most veterinarians adapt to the new instruments within 1-2 procedures. The improved control is immediately apparent. 

Procedural Changes

Staff preparation: Brief your surgical team on the modified sequence, particularly the early eyelid and third eyelid removal. 

Practice recommendations: Dr. Broadwater suggests starting with straightforward cases to build confidence with the new approach. 

Coming Up: Part 3

In our final installment, discover Dr. Broadwater’s advanced strategies for managing orbital bleeding using Vetigel® Hemostatic Gel and preventing the most common post-surgical complications that lead veterinarians back to surgery. 

The combination of proper positioning (Part 1) and specialized instruments (Part 2) sets the foundation for successful enucleation surgery. Part 3 will complete your toolkit for confident, efficient procedures.

Series 1: Enucleation Surgery Setup & Positioning | 15-Minute Technique

Transform your enucleation procedures from hour-long challenges to confident 15-20 minute surgeries. Dr. Josh Broadwater, DVM, DACVO, board-certified veterinary ophthalmologist with nearly 20 years of experience at Charlotte Animal Referral and Emergency in North Carolina, shares the revolutionary setup changes that make all the difference. 

“Many general practitioners find enucleation surgery intimidating. My goal is to help veterinarians become more comfortable with this surgery while reducing both complications and surgical time.” – Dr. Josh Broadwater, DVM, DACVO*

The Enucleation Surgery Challenge

Many general practitioners find enucleation surgery intimidating. Dr. Broadwater frequently hears from colleagues who struggle with procedures lasting an hour or longer, often accompanied by excessive bleeding and complications. His refined approach addresses these exact pain points with three key changes we’ll cover in this series. 

When Enucleation Surgery Is Necessary

Primary indications for eye removal surgery include:

  • Intractable pain conditions: Ruptured corneas and advanced glaucoma in blind eyes 
  • Ocular malignancies: Tumors within or around the eye 
  • Severe orbital infections: Cases unresponsive to medical management 
  • Traumatic injuries: Including ocular proptosis (Dr. Broadwater notes seeing unusually high numbers recently) 

Alternative Treatment Options Before Enucleation

Before proceeding with enucleation, discuss these permanent alternatives: 

Ciliary Ablation (CBA) 

  • Injection of 20-30mg gentamicin into vitreous cavity 
  • 85-90% success rate for glaucoma cases 
  • Less invasive, lower cost due to minimal sedation 
  • Risk: 10-15% may develop phthisical eyes over time 
  • Not suitable if secondary glaucoma caused by potential malignancy 

Intrascleral Prosthesis 

  • Removes internal eye structures while preserving cornea and sclera 
  • Maintains eye movement and blinking appearance 
  • Longer recovery period than enucleation 
  • Not ideal for cancer or infection cases 

Revolutionary Setup Change: Dorsal Positioning for Veterinary Eye Surgery

The most critical modification Dr. Broadwater recommends is positioning patients in dorsal recumbency rather than sternal. 

This single change can dramatically improve your surgical experience and outcomes. Most veterinarians are taught to position patients sternally, but Dr. Broadwater’s approach completely transforms the procedure. 

Why Dorsal Positioning Changes Everything

Traditional sternal positioning creates multiple challenges: 

  • Limited surgeon visibility into the orbital cavity 
  • Awkward angles for instrument access 
  • Surgeon standing/leaning creates fatigue and less precise control 
  • Gravity works against hemostasis 

Position Benefits for Enucleation Surgery:

  • Patient’s nose points straight toward ceiling – optimal anatomical alignment 
  • Eyelids parallel to surgical table – eliminates gravity-related tissue retraction 
  • Surgeon seated for better control – reduces fatigue and improves precision 
  • Significantly improved access to orbital cavity – clear visualization of all structures 
  • Easier navigation of the deep orbital “cave” – instruments follow natural anatomy 

Essential Equipment for Dorsal Positioning

Dr. Broadwater considers Vacuum Positioning Bags essential for consistent results. The vacuum bag allows you to mold perfect support around the patient’s body while maintaining precise head positioning. 

Key features: 

  • Conforms to any patient size or body shape 
    Maintains position throughout entire procedure 
    Eliminates need for multiple repositioning breaks 
    Provides stable platform for delicate surgical work 

Note from Dr. Broadwater: “I use Vacfix positioning bags, though they’ve become harder to find and more expensive. The investment is worth it for the consistency they provide.” 

Sterilized Leashes for Large Dogs

For patients with longer noses that might shift during surgery, Dr. Broadwater recommends using sterilized leashes to secure the head position. 

Application: 

  • Gently loop around muzzle area 
  • Secure to table to prevent movement 
  • Particularly important for breeds with elongated skulls 
  • Maintains precise anatomical alignment throughout surgery 

Setup Protocol for Dorsal Positioning:

  1. Place vacuum bag on surgical table
  2. Position patient in dorsal recumbency with nose pointing to ceiling
  3. Mold vacuum bag around patient’s body for support 
  4. Activate vacuum to lock position 
  5. Secure head with sterilized leash if needed for larger dogs 
  6. Verify eyelids are parallel to table surface 
  7. Confirm comfortable surgeon seating position 

Immediate Benefits You'll Notice

Veterinarians who switch to dorsal positioning report several immediate improvements: 

Enhanced Visualization 
The orbital cavity opens up like never before. Structures that were difficult to identify in sternal positioning become clearly visible, making the surgery more intuitive and educational. 

Improved Instrument Control 
Working with gravity instead of against it makes every movement more precise. Instruments follow natural anatomical curves rather than fighting awkward angles. 

Reduced Surgeon Fatigue 
Sitting comfortably instead of hunching over a sternally positioned patient reduces back strain and allows for steadier hands throughout the procedure. 

Better Hemostasis 
Gravity helps pool fluids away from the surgical site rather than obscuring your view, making bleeding control more manageable. 

Implementation Tips for Your Practice

Dr. Broadwater offers essential tips for your practice, including:

Staff Training Requirements 
Train your surgical team on the new positioning protocol before your first case. Practice the vacuum bag setup and head securing technique with a cooperative patient to work out any logistics. 

Cost Considerations 
While vacuum positioning bags represent an upfront investment, the time savings and reduced complications quickly justify the cost. Consider the value of cutting surgery time by 40+ minutes per procedure. 

Getting Started 
Dr. Broadwater recommends starting with straightforward cases to build confidence with the new positioning before tackling more complex enucleations.

Modern vs Traditional Hemostatic Agents: Which Works Best for Your Veterinary Practice?

Based on the continuing education webinar presented by Ann Marie Woyma, DVM.*  

Surgical bleeding remains one of the most significant challenges facing veterinary practitioners. Extended bleeding episodes increase anesthesia duration, elevate patient risk, and can transform routine procedures into complex cases requiring emergency intervention. 

Despite advances in surgical techniques, hemostatic control continues to rely heavily on methods developed decades ago. Recent developments in polymer-based hemostatic technology like Vetigel® hemostatic gel offer new approaches, but how do they compare to established methods? 

How Do Traditional and Modern Hemostatic Agents Work?

Veterinary practitioners have multiple hemostatic approaches available, each with distinct mechanisms of action. Understanding these differences is essential for selecting the right product for each clinical scenario. 

Traditional Matrix-Based Hemostatic Agents

Cellulose-based products, gelatin sponges, and collagen matrices provide scaffolding for natural clot formation through the patient’s coagulation cascade. 

Advantages: Well-established safety profile, cost-effective for routine procedures, familiar to most practitioners 

Limitations: Requires direct blood contact for activation, integrates with patient’s clot (removal disrupts hemostasis), variable effectiveness with high-pressure bleeding, can impair surgical visualization 

Modern Polymer-Based Hemostatic Technology

Plant-based polymers like Vetigel hemostatic gel create mechanical barriers through ionic crosslinking, independent of natural clotting mechanisms. 

Advantages: Immediate hemostatic effect regardless of patient coagulation status, non-integrating (removable without disturbing hemostasis), effective against high-pressure arterial bleeding, maintains clear surgical field 

Limitations: Higher cost per application, requires specific application technique, limited long-term comparative studies 

Clinical Evidence: A study comparing polymer-based agents like the Vetigel product showed 94% immediate hemostasis rates compared to 67% for traditional matrix agents in high-pressure bleeding scenarios. 

Which Hemostatic Agent Should You Choose for Different Species?

Species-specific factors significantly impact hemostatic agent selection and effectiveness in veterinary surgery. 

Canine Surgical Bleeding Control

Dogs tolerate most hemostatic agents well, but patient size impacts cost-effectiveness. Large breed surgical procedures may require multiple applications of any hemostatic product. 

Feline Surgical Considerations

Cats show particular sensitivity to prolonged anesthesia, making rapid hemostasis especially critical. Smaller surgical sites may favor precision-application products over broad-coverage traditional agents. 

Exotic Animal Hemostasis

Limited research exists on hemostatic agent safety in exotic species. Consultation with exotic veterinary specialists is recommended when considering newer technologies. 

What Are the Best Hemostatic Agents for Common Veterinary Procedures?

Matching the right hemostatic technology to specific surgical procedures maximizes both clinical outcomes and cost-effectiveness. 

Enucleation Surgery Bleeding Control

Clinical Comparison: Average procedure time with traditional methods (45-60 minutes) versus Vetigel hemostatic gel polymer technology (35-45 minutes). Post-operative complications: Traditional approach (15% discharge issues) versus Vetigel product-based hemostasis (3% discharge issues) when properly removed. 

Economic Analysis: Higher product cost is offset by reduced anesthesia time and fewer complications. 

Dental Extraction Bleeding Control

Extraction sites in highly vascular oral tissue present difficult access for traditional ligation. Full-mouth extractions show 30% reduction in total anesthesia time with advanced hemostatic protocols using products like Vetigel hemostatic gel. 

Mass Removal and Soft Tissue Surgery

Small masses: Traditional methods often sufficient Large masses/mastectomies: Advanced agents like Vetigel hemostatic gel provide better coverage Vascular masses: The Vetigel product shows superior high-pressure bleeding control. 

When Should Your Practice Use Traditional vs Modern Hemostatic Agents?

Developing clear selection criteria helps optimize both clinical outcomes and practice profitability based on case-specific factors. 

When Traditional Methods Remain Optimal:

  • Routine procedures with minimal bleeding expected 
  • Cost-sensitive cases where bleeding is easily controlled 

When Advanced Technology Provides Value:

  • High-risk patients who cannot tolerate blood loss 
  • Procedures with historically difficult hemostatic control 
  • Emergency situations requiring immediate bleeding cessation 
  • Cases where surgical visualization is critical
  • Coagulopathic patients or those on anticoagulants

Products like Vetigel hemostatic gel excel in these scenarios due to their coagulation-independent mechanism and rapid action.  

Economic Considerations by Practice Type:

  • High-Volume/Low-Cost Practices: Traditional agents for routine cases, Vetigel hemostatic gel for complications
  • Specialty Practices: The Vetigel product as standard for complex procedures
  • Emergency Clinics: Stock both options based on case severity assessment 

How to Successfully Integrate Modern Hemostatic Agents into Your Practice

Transitioning to advanced hemostatic technology requires systematic implementation rather than wholesale practice changes. This phased approach maximizes success while controlling costs. 

Phase 1: Assessment (Months 1-2)

Diagnosing Feline Hyperthyroidism: Why the TRUFORMA® Biosensor Testing Platform’s Feline TSH Test Outperforms Traditional Methods 

Based on the continuing education webinar presented by Dr. Kristin Marzin, DVM* 

Feline hyperthyroidism affects 10% of geriatric cats, making it the most common endocrine disorder in veterinary medicine. Yet for many practitioners, diagnosing borderline cases remains frustratingly difficult. Does this scenario sound familiar? You have a 12-year-old cat with weight loss and a palpable thyroid nodule, but the T4 comes back normal. Do you treat? Wait and retest? Send out for more diagnostics and wait days for results? 

Traditional testing methods leave veterinarians in diagnostic gray zones far too often—and waiting for send-out labs delays treatment decisions. The TRUFORMA® platform’s feline-specific TSH test changes that, offering the sensitivity and specificity needed to confidently diagnose hyperthyroidism in 20 minutes, right in your clinic. 

The Problem: Total T4 Testing Misses Up to 10% of Hyperthyroid Cats

While approximately 90% of hyperthyroid cats can be diagnosed through clinical signs and elevated T4, a significant percentage of cases fall into diagnostic gray zones. Several factors complicate diagnosis: 

  • Early disease stages where T4 values haven’t elevated yet 
  • Normal T4 fluctuations that may drift in and out of reference ranges 
  • Non-thyroidal illness that can suppress T4 values into normal ranges 

The 2016 AAFP guidelines for hyperthyroid management organize these challenging cases into six categories, with most requiring either repeated T4 testing or additional thyroid hormone testing to confirm or exclude hyperthyroidism. 

Why Free T4 Falls Short in Real-World Practice

Traditionally, free T4 (measured by equilibrium dialysis) has been used to support hyperthyroid diagnosis in cats, offering nearly 99% sensitivity. However, this highly sensitive test has limitations: 

  • Free T4 can be normal, increased, or decreased in cats with non-thyroidal illness 
  • Should not be used as the sole confirmatory test 
  • Newer chemiluminescent methods show questionable accuracy, consistently undervaluing results compared to equilibrium dialysis 
  • Not recommended for monitoring cats following radioactive iodine therapy 

Feline TSH vs. Canine TSH: Why Species-Specific Testing Matters

In hyperthyroid cats, autonomously secreted thyroid hormones suppress TSH production to near-zero levels—a finding that should make TSH testing ideal for diagnosis. The problem? Canine TSH assays weren’t designed for feline physiology. 

  • Normal feline TSH range is often lower than the canine assay’s lower limit of quantification 
  • Canine TSH cannot reliably differentiate between healthy cats and those with non-thyroidal illness 
  • Cannot be used as a sole diagnostic test 

Despite these limitations, research by Dr. Mark Peterson’s group examining 917 hyperthyroid cats demonstrated that serum TSH concentrations are suppressed in 98% of hyperthyroid cats, with median TSH below 0.03 ng/mL compared to 0.05 ng/mL in clinically normal cats. The study found that only 2% of hyperthyroid cats had measurable canine TSH concentrations, while nearly 70% of euthyroid cats had detectable levels. This meant that finding a measurable canine TSH could help rule out hyperthyroidism in cats, though the test showed poor specificity (69.9%) when used alone. 

The key insight: while canine TSH could be somewhat useful for screening, its lack of sensitivity in the low range where feline values typically fall—combined with poor specificity—highlighted the critical need for a feline-optimized assay. 

How the TRUFORMA® Platform's Feline TSH Test Solves the Diagnostic Puzzle

Zomedica developed the TRUFORMA biosensor testing platform’s feline-verified TSH test to address every limitation of canine assays—with technology optimized specifically for feline physiology and delivered through the only in-clinic platform available. Here’s what makes the TRUFORMA® platform test different: 

The Only In-Clinic Feline TSH Test Available

The TRUFORMA system is the only point-of-care platform offering feline-specific TSH testing. Get accurate results in 20 minutes—no send-outs, no waiting, no delayed treatment decisions. Diagnose and create treatment plans in the same appointment, improving both patient outcomes and client satisfaction. 

3X More Sensitive Than Canine TSH

The TRUFORMA platform’s feline TSH test has a lower limit of detection of 0.008 ng/mL compared to 0.03 ng/mL for canine TSH—providing the precision needed to accurately measure feline TSH values in the critical low range where feline physiology operates. 

Prevents Misdiagnosis in 12% of Healthy Cats

TRUFORMA platform test clinical data from 170 feline samples revealed: 

  • 95% of healthy cats had serum TSH above 0.01 ng/mL
  • 93% of hyperthyroid cats had TSH below 0.01 ng/mL 
  • 12% of normal cats tested below the canine assay’s detection limit but had measurable TSH with the TRUFORMA platform test—preventing false positive diagnoses and unnecessary treatment 

Proven Precision You Can Trust

The TRUFORMA platform’s multi-instrument testing showed coefficient of variation less than 10%—2.5X better than industry standards—ensuring consistent, reliable results. 

Critical Application: Detecting Iatrogenic Hypothyroidism

Here’s a sobering statistic: Nearly 50% of treated hyperthyroid cats develop iatrogenic hypothyroidism, regardless of treatment method. Even more concerning? T4 monitoring alone misses almost 80% of these cases. 

Why does this matter for your patients? 

  • Decreased GFR and progression to azotemic chronic kidney disease 
  • 50% shorter median survival time in cats that become azotemic 
  • Subtle clinical signs easily missed or attributed to aging 

The solution: The TRUFORMA  platform’s T4 test and feline TSH test combination identifies these cases early. When you see low or low-normal T4 with elevated TSH, you can adjust methimazole doses or add thyroid supplementation before kidney damage progresses—all with same-day results that enable immediate intervention. 

Catching Hyperthyroidism Earlier: The TRUFORMA Platform Advantage

Traditional send-out testing often catches hyperthyroidism only after significant organ damage has occurred—and delays treatment by days while you wait for results. The TRUFORMA biosensor testing platform changes this timeline by identifying cats in the earliest disease stages with same-appointment results, enabling intervention when it’s most effective and before irreversible complications develop. 

Early detection means: 

  • Prevention of cardiac remodeling and hypertension 
  • Reduced risk of kidney damage from hyperfiltration 
  • Better treatment outcomes with less aggressive intervention 
  • Improved quality of life for your feline patients 

The Research Behind the TRUFORMA Platform's Feline TSH Test

Recent peer-reviewed research published by Dr. Mark Peterson compared the TRUFORMA platform’s feline-optimized TSH assay with chemiluminescent canine TSH testing across multiple patient populations: hyperthyroid cats, radioiodine-treated cats, chronic kidney disease patients, and healthy cats. 

The verdict? The TRUFORMA platform’s feline-specific test demonstrated superior sensitivity and specificity across all groups, offering a more practical alternative to thyroid scintigraphy for practices without nuclear medicine capabilities—with the critical advantage of in-clinic results in 20 minutes. 

Implementing The TRUFORMA Biosensor Testing Platform in Your Practice

The TRUFORMA platform’s T4 + feline TSH is becoming the new diagnostic standard, replacing the T4/free T4 send-out combination for hyperthyroid workup. The TRUFORMA in-clinic biosensor testing platform offers value across your entire case management workflow: 

Initial diagnosis of suspected hyperthyroidism—results in 20 minutes 

 ✓ Routine wellness screening in geriatric cats during annual exams 

 ✓ Treatment monitoring to prevent iatrogenic hypothyroidism 

 ✓ Differentiating subclinical hyperthyroidism from non-thyroidal illness 

Same-day diagnosis means same-day treatment decisions—improving patient outcomes, increasing client satisfaction, and eliminating the frustration of waiting for send-out results while your patient continues to deteriorate. 

Ready to bring same-day feline hyperthyroid diagnosis to your practice? The TRUFORMA in-clinic biosensor testing platform is the only point-of-care system offering feline-specific TSH testing. Get accurate results in 20 minutes and make confident treatment decisions in the same appointment.

Veterinary Cardiac Testing: Advanced Heart Disease Diagnostics Equipment

Based on clinical insights from Dr. Gary Oswald’s webinar, When the Heart Cries for Help. Using NT-proBNP in Canine Cardiac Disease*

Heart disease affects millions of dogs and cats, yet most cases go undetected until patients present in crisis. Studies show that many cardiac conditions remain hidden for months or years before becoming clinically apparent, often making their first appearance as sudden death or acute heart failure. The TRUFORMA® diagnostic system revolutionizes veterinary cardiac care by bringing advanced heart disease testing directly into general practice, enabling early detection and better patient outcomes through rapid NT-proBNP cardiac biomarker analysis. 

The Hidden Epidemic: Heart Disease in Veterinary Practice

Heart disease represents one of the most challenging diagnostic areas for general practitioners, with traditional methods often failing until disease reaches advanced stages. 

Common Diagnostic Challenges: 

  • Physical examination may appear normal in early disease stages 
  • Heart murmurs can be absent in many cardiomyopathy cases 
  • Chest radiographs often show no changes until heart failure develops 
  • ECG abnormalities frequently absent in subclinical patients 
  • Patient stress during examination masks subtle signs 

Clinical Reality: Many pets with significant heart disease show no obvious symptoms during routine wellness visits, leaving veterinarians without clear indicators to pursue cardiac evaluation. 

The Cost of Late Detection

Patient Impact: 

  • First symptom often sudden death or acute heart failure 
  • Advanced disease requires more aggressive, expensive treatment 
  • Shorter lifespan and reduced quality of life 
  • Limited treatment options once heart failure develops 

Practice Impact: 

  • Emergency presentations requiring immediate referral 
  • Client dissatisfaction when disease “appears suddenly” 
  • Missed opportunities for preventive care 
  • Higher liability risk from undiagnosed conditions 

How to Diagnose Heart Disease in Dogs and Cats

Subtle Symptoms Pet Owners Report: 

  • Exercise intolerance or tiring more easily during walks 
  • Heavy breathing during normal activities 
  • Restlessness at night or difficulty settling 
  • Coughing episodes especially at night or early morning 
  • Decreased appetite or reluctance to eat 
  • Weight loss despite normal eating habits 

Clinical Signs for Veterinarians: 

  • Soft heart murmurs that may be intermittent 
  • Increased respiratory effort during examination 
  • Pale or slow capillary refill indicating poor circulation 
  • Weak pulses or pulse deficits 
  • Behavioral changes such as hiding or decreased activity 

Traditional Diagnostic Limitations

Physical Examination Challenges: While cardiac auscultation remains important, many patients with significant heart disease present with normal or only subtle examination findings, particularly cats with cardiomyopathies and dogs with early dilated cardiomyopathy. 

Radiographic Limitations: Chest X-rays frequently appear normal in subclinical cardiac patients. Even when abnormalities are present, distinguishing cardiac from respiratory causes can be challenging, especially in emergency situations. 

The Diagnostic Gap: General practitioners need reliable tools to identify cardiac disease before clinical signs develop, allowing for early intervention and improved patient outcomes. 

Advanced Heart Disease Testing: The NT-proBNP Solution

NT-proBNP (N-terminal pro-B-type natriuretic peptide) serves as the heart’s “cry for help,” providing objective evidence of cardiac stress when traditional diagnostic methods fall short. 

How Cardiac Biomarkers Work: When the heart experiences stress from increased pressure or volume, cardiac cells produce a hormone called pro-BNP. This molecule is then split into two parts: 

  • Active BNP: Helps the body manage cardiac stress by promoting blood vessel dilation and kidney function 
  • NT-proBNP: Inactive fragment that remains in the bloodstream longer and can be easily measured 

Clinical Advantage: NT-proBNP levels rise significantly before clinical signs appear, enabling early detection of heart disease in apparently healthy patients. 

Why NT-proBNP Testing Transforms General Practice

Immediate Clinical Applications: 

  • Emergency triage of patients with breathing difficulties 
  • Pre-anesthetic screening for high-risk patients 
  • Wellness screening in breeds prone to heart disease 
  • Treatment monitoring for patients with known cardiac conditions 

Practice Benefits: 

  • 15-minute results for immediate clinical decision-making 
  • Objective data to support clinical findings 
  • Client confidence in advanced diagnostic capabilities 
  • Early intervention opportunities improving patient outcomes 

Signs of Heart Failure in Pets: When to Test

Dogs Presenting with Breathing Difficulties: Emergency differentiation between heart and lung problems is critical for appropriate treatment. Traditional methods often leave uncertainty in diagnosis. 

Common Emergency Presentations: 

  • Labored breathing with or without coughing 
  • Exercise intolerance or collapse during activity 
  • Loud heart murmurs in breeds not typically affected 
  • Distended abdomen potentially indicating heart failure 
  • Anxiety or restlessness especially at night 

NT-proBNP Reference Values for Dogs: 

  • Below 900 pmol/L: Respiratory cause likely, heart failure unlikely 
  • Above 2500 pmol/L: Congestive heart failure probable 
  • 900-2500 pmol/L: Consider pulmonary hypertension, pursue cardiac evaluation 

Cat Heart Problems: Silent Disease Detection

Feline Cardiac Disease Challenges: Cats excel at hiding cardiac disease, often showing no symptoms until presenting in acute heart failure or sudden death. 

When to Suspect Feline Heart Disease: 

  • Any heart murmur detected during examination 
  • Breathing difficulties or open-mouth breathing 
  • Sudden onset of rear limb paralysis 
  • Hiding behavior or decreased activity 
  • Poor appetite or weight loss 

NT-proBNP Reference Values for Cats: 

  • Below 100 pmol/L: Heart disease unlikely 
  • Above 300 pmol/L: Significant cardiac disease probable 
  • Special consideration: All cats with heart murmurs should receive NT-proBNP testing

TRUFORMA System vs. Send-Out Testing

Breed-Specific Cardiac Screening Guidelines

High-Risk Canine Breeds 

Dilated Cardiomyopathy-Prone Breeds: 

  • Doberman Pinschers: Special consideration with lower threshold (700 pmol/L) 
  • Great Danes: Standard screening protocols 
  • Irish Wolfhounds: Annual screening recommended 
  • Standard Schnauzers: Begin screening at 4-5 years 
  • Boxers: Monitor for both DCM and arrhythmogenic cardiomyopathy 

Breed-Specific Considerations: Labrador Retrievers, Newfoundlands, Greyhounds: May have elevated NT-proBNP values (>900 pmol/L) even with normal hearts. Pursue cardiac evaluation but normal echo findings are not uncommon in these breeds. 

High-Risk Feline Breeds 

Hypertrophic Cardiomyopathy-Prone Breeds: 

  • Maine Coons: Begin screening at 2-3 years 
  • Ragdolls: Annual testing recommended 
  • Sphynx cats: High predisposition requires early screening 
  • British Shorthairs: Include in routine wellness protocols 
  • Persians: Consider screening all breeding animals 

Universal Feline Screening: Given the difficulty in detecting feline heart disease through examination alone, many specialists recommend annual NT-proBNP screening for all adult cats as part of routine wellness care.
