Fluid management in extensive liposuction: A retrospective review of 83 consecutive patients.

Tumescent anesthesia makes it feasible to perform liposuction in an office setting. There are often patients who desire extensive liposuction on approximately 30% of total body surface area, which means the potential of fluid overload. In this study, the charts of 83 patients undergoing extensive liposuction were retrospectively reviewed. The intra-operative fluid ratio was 1.66 for the extensive liposuction. There were no episodes of pulmonary edema, congestive heart failure exacerbation, or other major complications. The average urine output in the operating room, the recovery room, and while on the floors was 1.35, 2.3, and 1.4 mL/kg/hour respectively. Intravenous (IV) fluid administration during operation was minimized to approximately 300 to 500 mL. The total volume of IV injection was also reduced to less than 1500 mL when the patient was in the recovery room and on the hospital floor. Our fluid management strategy in extensive liposuction reflects minimal risk of volume overload. Foley catheters are not applied and patients could resume oral intake in usual, so they can discharge after 6 hours of recovery room stay in our daily practice.
