How to Predict Post-Surgical Bleeding and Hemoglobin in Liposuction?

Recruiting

• Conditions: Bleeding; Surgery
• Interventions: Procedure: Liposuction

• Registration Number: NCT06453772
• Lead Sponsor: Instituto Mexicano del Seguro Social

Brief Summary

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.

Detailed Description

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).
