Background: Fluid management in large volume liposuction is still a big challenge. The objective of the research was to contrast the hemodynamic parameters of fluid resuscitation utilizing the Rohrich formula with those guided by cardiometry stroke volume variations in patients undergoing large volume liposuction surgeries.

Methods: Fifty patients undergoing large volume liposuction had been randomized into 2 groups. Rohrich formula group (RF): patients were given IV fluids, managed by Rohrich formula in which intraoperative fluid ratio (IOFR) was 1.2. Electrical cardiometry group (EC): patients received IV fluids according to EC guided stroke volume variation (SVV) and administering intravenous infusion of lactated Ringer's solution (4 ml per kg over 15 minutes) when SVV ˃ 15%. Fluid maintenance (2 ml/kg/h) of lactated ringer was administrated in both groups. Oxygen saturation (SPO2), Mean arterial blood pressure (MAP), heart rate (HR) were continuously monitored and documented besides urine output (UOP), blood volume in aspirate, venous hemoglobin, total aspirate and fluids.

Results: MAP was maintained in both groups, SPO2, HR, infiltrated fluids, hemoglobin and blood volume in aspirate were comparable (p˃ 0.05). UOP, IOFR and IV fluids were statistically higher in RF (1.4 ± 0.12 ml/kg/h, 1.2, 2.55 ± 0.52 L) compared to EC (1.2 ± 0.09 ml/kg/h, 1.01 ± 0.03, 1.52 ± 0.55 L) respectively. No consequences had been observed in either group.

Conclusion: EC guided SVV is more accurate than RF regarding fluid management in patients undergoing large volume liposuction surgeries.
