Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Patients undergoing liposuction

Liposuction

Intervention Type PROCEDURE

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.
