ABSTRACT
BACKGROUND:
Ultrasound-guided costal margin block (CMB) is a superficial and easily applicable technique. The current study aims to investigate its analgesic efficacy in patients undergoing laparoscopy-assisted gastrectomy and describe its feasibility.METHODS:
Forty-two patients undergoing laparoscopy-assisted gastrectomy were enrolled in this prospective, double-blind, randomized clinical trial. Patients were randomized to receive standard general anesthesia with (block group, n = 21) or without (control group, n = 21) ultrasound-guided bilateral CMB. The primary outcome was 24-h intravenous morphine equivalents after surgery. Secondary outcomes included consumption of titrated morphine, 24-48 h morphine equivalents, consumption of intraoperative remifentanil, numerical pain rating scale scores, time to first opioid dose, patient satisfaction, adverse effects, and recovery events.RESULTS:
The postoperative 24-h morphine equivalents in the block group were significantly reduced compared to the control group (14.4 ± 7.4 mg vs. 29.9 ± 9.8 mg, p < 0.001). Both the titrated morphine consumption in the post-anesthesia care unit (PACU) and intraoperative remifentanil consumption were lower in the block group than in the control group. Patients in the block group had relatively lower average pain scores in PACU and reported more satisfaction with pain relief. Adverse effects and hospital length of stay after surgery were comparable between the two groups (p > 0.05).CONCLUSION:
As a novel and easily-performed technique, ultrasound-guided bilateral CMB can reduce opioid consumption in patients undergoing laparoscopy-assisted gastrectomy.Palavras-chave
