BACKGROUND: Intraoperative blood loss (BL) and subsequent hemoglobin (Hb) decline remain significant safety concerns in body contouring procedures. Also, the role of body mass index (BMI) in predicting BL and the comparative safety of excisional versus non-excisional procedures have not been fully characterized.
OBJECTIVES: To determine Hb changes, BL, and the role of BMI among patients underwent body contouring procedures.
METHODS: A prospective cohort study included 33 consecutive patients (ASA I-II, aged 21-54 years) who underwent either liposuction alone or liposuction combined with excisional body contouring (abdominoplasty, brachioplasty, thigh lift, or back lift) for cosmetic reasons at Royal Private Hospital, Sulaimaniyah, Iraq, from April 2024 to May 2025. All procedures utilized a standardized wetting solution (1 mg epinephrine, 10 cc of 1% lidocaine and 100 mg tranexamic acid per 500 ml normal saline). Blood content in lipoaspirate was measured after 20 min and Hb levels were recorded preoperatively and 24 h postoperatively.
RESULTS: Among patients, 17 (51.52%) underwent excisional and 16 (48.48%) non-excisional procedures. There were no significant differences between groups in preoperative Hb (12.71 ± 0.99 vs. 12.75 ± 1.06 g/dl, p = 0.915), postoperative Hb (10.95 ± 1.19 vs. 11.21 ± 1.05 g/dl, p = 0.526), blood volume (BV) in lipoaspirate (504.1 ± 316.8 vs. 561.3 ± 366.8 ml, p = 0.635), or blood transfusion (BT) rates (35.3% vs. 25%, p = 0.708). BMI showed a moderate positive correlation with blood in lipoaspirate (Spearman's r = 0.407, p = 0.019), and linear regression confirmed BMI as a significant predictor explaining 13.9% of variance in BV (R2 = 0.139, p = 0.033). Postoperative complications occurred non-significantly in only 3 patients (9.09%) (p = 0.601).
CONCLUSIONS: The addition of excisional components did not significantly increase acute BL or Hb decline compared to liposuction alone, likely due to standardized TXA and epinephrine infiltration. Higher BMI was significantly associated with greater blood content in lipoaspirate and might be considered a predictor of intraoperative bleeding.
