Study Notes
Anesthesia for Liposuction Surgery
- Obesity/Lipodystrophy: BMI is calculated from height and weight (kg/m²).
- Overweight: BMI > 25 kg/m².
- Obese: BMI > 30 kg/m².
- Severely obese: BMI > 40 kg/m².
- Pathophysiologic changes in obesity are summarized elsewhere (see Box 44.1).
Surgical Procedure
- Common Procedure: Suction-assisted lipoplasty is a frequent cosmetic surgery in the U.S.
- Method: Removing subcutaneous fat using a cannula and suction.
- Wetting Solution: May contain additives like lidocaine with epinephrine.
- Laser-assisted Liposuction: May be used with wetting solution to improve aspiration volume.
- Bariatric Surgery Impact: Massive weight loss from bariatric surgery increases the number of body contouring procedures.
