Liposuction — Anatomy, Fluid Management, Cannula Physics, and Safety

This episode reviews the core principles of liposuction and body contouring, focusing on surgical anatomy, patient selection, fluid management, cannula physics, and safety.Topics include the three surgical fat layers, superficial fascial system anatomy, zones of adherence, ideal liposuction candidates, BMI and skin tone considerations, Valsalva testing, the Diver’s test, standing markings, super-wet versus tumescent infiltration, lidocaine safety, large-volume liposuction, and IV fluid replacement. The episode also covers suction-assisted, power-assisted, ultrasound-assisted, VASER, laser-assisted, and SAFE liposuction, including Poiseuille’s law, cavitation, thermal injury prevention, the Prado study, the 40-40-20 SAFE technique, regional anatomy, surgical endpoints, meralgia paresthetica, DVT/PE prevention, and fluid overload. Part of Dr. Lara’s Plastic Surgery Compendium — a high-yield audio reference for plastic surgery trainees and surgeons.DisclaimerThis podcast is intended for educational purposes only and is designed for medical students, residents, fellows, and practicing healthcare professionals.
