Relation between liposuction volume and perioperative intravenous fluid

Abstract

Balance in fluids as in any other surgical procedure, is obtained by having a balance between losses during surgery and fluids administered for replacement. The challenge in liposuction is to quantify bleeding with certainty, as well as the ingress and loss of transoperative fluid. Objective: To find relation between vacuum volume and fluid replenishment in the perioperative of liposuction surgery. Studio and design Observational, retrospective, longitudinal study. Material and methods: Patients undergoing lipodystrophy of the abdomen or back under general anesthesia who were underwent to liposuction with conventional liposupctor or VASER type during August 2013 to May 2016. Demographic data such as ; age, gender, body mass index (BMI), anesthetic risk estimation by ASA classification (American Society of Anesthesiologists),liposuction technique performed, liposuction volume, administered IV fluids and diuresis in the trans and postoperative were recorded. Statistical analysis: ni-varied descriptive analysis throughout the sample, the estimation of mean and standard deviation for numerical variables that follow a normal distribution and frequencies for qualitative variables. As well as a simple linear regression with Pearson correlation coefficient, perfect=1, to find a relation between lipoaspirated volume and intra and postoperative fluids IV, being considered significant with a p< 0.05. Results: 112, clinical records were included, mostly for women 97.3%,with a mean of 34.46 years and a body mass index (BMI) of 25.4, 75% were ASA I, There is no significant relationships between transoperative solutions IV and lipoaspired. A low correlation was obtained between liposuction volume and postoperative solutions IV (r.216; with p<.05) as well as the correlation of trans operative solutions IV and diuresis (r.224; p<.05). Conclusion: In this observational and retrospective study there was no direct and significant correlation between liposuction volume and the amount of trans operative fluids. Correlation with postoperative fluids IV was significant but low.
