Fluid resuscitation in liposuction: a retrospective review of 89 consecutive patients.
BACKGROUND
In 1998, the senior author presented the intraoperative fluid ratio, defined as the volume of super-wet solution and intraoperative intravenous fluid divided by the aspiration volume, to guide resuscitation fluid volumes in super-wet liposuction. The senior author demonstrated that intraoperative fluid ratios of 2.1 for small-volume and 1.4 for large-volume liposuction were safe and did not cause volume overload sequelae. A high urine output was common and reflected a mild overresuscitation, which could have adverse consequences in patients with undiagnosed cardiopulmonary disease. The purpose of this study was to compare overresuscitation sequelae in a cohort of consecutive super-wet liposuction patients using a new fluid management formula in which replacement fluid was given after 5000 cc of lipoaspirate instead of 4000 cc, as initially described.


METHODS
The charts of 89 consecutive patients undergoing super-wet liposuction were retrospectively reviewed.


RESULTS
The intraoperative fluid ratio was 1.8 for the small-volume reductions (< 5000 cc, n = 68) and 1.2 (> 5001 cc, n = 21) for the large-volume reductions. 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 floor was 1.5, 1.6, and 2.9 cc/kg/hour for the small-volume group and 1.7, 1.8, and 2.5 cc/kg/hour for the large-volume group.


CONCLUSIONS
The super-wet subcutaneous infiltration liposuction technique for both small- and large-volume reductions is safe and can be performed without adverse cardiopulmonary sequelae. Given the high urine outputs, the intraoperative fluid ratio can be further improved by possibly eliminating the replacement fluid altogether.
