ESPB patients received ultrasound-guided ESPB at T9 vertebrae level with 20 ml bupivacaine 0.5%. Control group patients did not receive a block. Total fentanyl consumption in the first 24 h and visual analogue scale (VAS) score for pain were evaluated postoperatively. Unpaired Student’s t-tests, chi-square tests, and Z tests were used to compare groups.Results: No significant differences were recorded between the groups regarding age, weight, ASA physical status, or surgery duration, Total fentanyl consumption in the first 24 h was significantly higher in the control group than the ESPB group (P=0.003; 485±20.39 mcg vs 445±67.49 mcg, respectively), VAS for pain was significantly higher in the control group for the first 12 h postoperatively.Conclusions: Bilateral ESPB provided effective postoperative analgesia and markedly decreased postoperative fentanyl consumption in patients undergoing an abdominal hysterectomy.Keywords: erector spinae plane block, fentanyl consumption, total abdominal hysterectomy, postoperative analgesia
