Veterinary Surgery July 2025 – Ortho & Soft Tissue Part 1: Hip Modeling, Low Pressure Laparoscopy & Heated Gas

In this Simini Small Animal Surgery Podcast episode, we explore three research-driven updates from the July 2025 issue of Veterinary Surgery. These studies challenge assumptions and refine surgical technique across both orthopedic modeling and minimally invasive soft tissue surgery.

We cover:

✅ Mazdarani et al. — A feline limb press model study revealing how rigid femoral fixation misrepresents real muscle forces. Flexion-friendly models better replicate in vivo biomechanics—potentially reshaping how we interpret feline stifle repair research.

✅ Chik et al. — A prospective study showing that brief pre-insufflation stretching improves working space during canine laparoscopy—enabling lower pressures and potentially safer MIS procedures with no compromise on space.

✅ Ferreira et al. — A randomized trial of heated CO₂ insufflation in dogs. The result? Significant temperature protection, delayed hypothermia onset, and a smoother recovery—especially important for longer or complex laparoscopic procedures.

Three studies. One message: smarter technique starts with smarter assumptions.

🎓 Journal Articles Discussed:

• Mazdarani et al. — Proximal femoral fixation method and axial load affect simulated muscle forces in an ex vivo feline limb press
• Chik et al. — Prestretching increases working space at the same insufflation pressure in dogs undergoing laparoscopic procedures
• Ferreira et al. — Effect of heated pneumoperitoneum on body temperature in dogs undergoing laparoscopic ovariectomy—A randomized controlled trial
