Özet
Objective: Elevated body mass index (BMI) complicates nerve block procedures and exacerbates postoperative pain. This study evaluated the association between BMI and pain outcomes in lumbar disc herniation (LDH) surgery. Method: This prospective observational study included 75, ASA I-III patients undergoing LDH surgery. Patients were assigned to three groups based on their BMI: Group-I (18-24.9 kg m-2), GroupII (25-29.9 kg m-2), and Group-III (30-40 kg m-2). An erector spinae plane block was performed under ultrasound guidance at the lumbar transverse process level (15 mL of 0.25% bupivacaine per side). Compared parameters included age, BMI, gender, perioperative complications, anesthesia and surgery duration, postoperative pain scores (Visual Analog Scale; VAS), and additional analgesic consumption. Results: A total of 75 patients were included. In Group-III, remifentanil consumption, block duration, failed attempts, and additional analgesia were significantly higher than in Group-I (p < 0.05). VAS pain scores differed significantly among the three groups at all assessed postoperative time points (all p < 0.001). Group-II and Group-III had significantly higher VAS-Rest (VAS-R) and VAS-Cough (VAS-C) scores at the 1st, 2nd, 6th, 12th, and 24th hours compared with Group-I. Similarly, VAS-R and VAS-C scores at the 1st, 6th, 12th, and 24th hours were significantly higher in Group-III than in GroupII. Additional analgesia was required in 35 patients (46.7%), significantly more frequent in obese patients (Group-III) (72%). Conclusion: Higher BMI was associated with elevated pain scores, greater analgesic requirements, increased remifentanil consumption, more failed attempts, and prolonged block times. Obese patients should therefore be evaluated more carefully for postoperative pain management.
