INTRODUCTION / AIMS: Laparoscopic sleeve gastrectomy is one of the most common surgical procedure that is chosen for bariatric surgery. Postoperative pain after bariatric surgery can be significant and challenging. Narcotic analgesics are often used to manage the postoperative pain in patients undergoing bariatric surgery. However, these drugs causes many undesirable adverse effects such as nausea, constipation, and respiratory depression. The primary aim of this prospective, randomised study was to evaluate of erector spinae plane (ESP) block on postoperative analgesic consumption in patients undergoing laparoscopic bariatric surgery. The secondary outcome measure was to evaluate the patients' postoperative Numeric Rating Scale (NRS) scores.
MATERİALS and METHODS: Fifty four ASA status II-III patients aged between 18 and 65 years and body mass index (BMI) 40-60 kg/m2 who underwent elective laparoscopic bariatric surgery were allocated randomly into two groups: ESP block group and control group. Postoperative analgesia was evaluated by using NRS scores. The NRS scores were recorded postoperative 0 (obtained within PACU), 20, and 40. min and then at 1, 3, 6, 12, 18 and 24 h.
RESULTS: The 24 h tramadol consumption with patient controlled analgesia (PCA) was determined to be statistically significantly less in the ESP block group (p <0.05). At all the measured time points, except 24. h NRS scores, the pain scores of the ESP block group were statistically lower (p <0.05). Additionally, intraoperative fentanyl consumption was significantly lower in the ESP block group (p <0.05).
DISCUSSION / CONCLUSION: ESP block performed under ultrasound guidance has more effective and long-lasting analgesic effect and decrease in analgesia requirement in patients undergoing laparoscopic bariatric surgery.
