To evaluate the effect of using a mathematical model developed through pre- and post-surgical hemoglobins to predict the volume to aspirate in patients undergoing primary body liposuction.
Postoperative anemia is a significant risk associated with liposuction, yet the scientific literature lacks detailed data on blood loss relative to the volume of fat removed. To address this, the investigators aimed to develop a mathematical formula predicting the decrease in postoperative hemoglobin (Hb post) based on preoperative hemoglobin (Hb pre), Body Mass Index (BMI), and the volume of fat suctioned. An observational, analytical, non-experimental, prospective study was conducted on liposuction patients to validate this predictive formula. Statistical analysis using Spearman's test showed that the results were statistically significant (P \< 0.05).
Study Type
OBSERVATIONAL
Enrollment
700
Primary or secondary liposuction is performed by the surgical staff. The study analyzed variables including weight, height, BMI, preoperative hemoglobin, and aspirated volume. Additionally, preoperative hemoglobin (Hb), hematocrit (Hto), platelets, prothrombin time (Tp), partial prothrombin time (TpT), and International Normalized Ratio (INR) were evaluated. Hb and Hto levels were reassessed 24 hours post-surgery to monitor changes.
