OBJECTIVES To investigate the analgesic effects of ESPB on pain control after laparoscopic liver resection compared with conventional pain management.
DESIGN Prospective, randomised controlled study.
SETTINGA single tertiary care centre from February 2019 to February 2020.
PATIENTS A total of 70 patients scheduled to undergo laparoscopic liver resection.
INTERVENTIONS In the control group (n=35), no procedure was performed. In the ESPB group (n=35), ESPB was performed after induction of general anaesthesia. A total of 40ml of ropivacaine 0.5% was injected at the T9 level bilaterally. After surgery, intravenous fentanyl patient-controlled analgesia was initiated. Fentanyl and hydromorphone were administered as rescue analgesics.
干预措施:对照组(n = 35)未进行疼痛干预。
ESPB组(n = 35)在全麻诱导后进行ESPB。共40ml 0.5%罗哌卡因在T9水平双侧注射。
MAIN OUTCOME MEASURES The primary outcome was the cumulative postoperative opioid consumption at 24h (morphine equivalent). The secondary outcomes were rescue opioid (fentanyl) dose in the postanaesthesia care unit (PACU) and pain severity at 1, 6, 12, 24, 48 and 72h, assessed using a numerical rating scale (NRS) score.
