Résumé
Laparoscopic hepatectomy is associated with trauma and severe pain. We examined whether bilateral, ultrasound-guided, single-injection erector spinae plane block (ESPB) could improve on postoperative analgesia compared with patient-controlled intravenous analgesia in patients undergoing laparoscopic hepatectomy. Fifty adults were randomly allocated to receive patient-controlled intravenous analgesia alone or combined with bilateral single-injection ESPB (ropivacaine 0.5%, 15 ml on each side). Primary outcome was resting pain scores at 3 h postoperatively assessed with visual analogue scale (VAS). Secondary outcomes included VAS scores at rest and during movement at 6, 12, 16, 20, 24, 48, and 72 h postoperatively; use of intraoperative opioids; postoperative rescue analgesia; sleep quality; time of first ambulation; ESPB-related complications; and ropivacaine concentration in plasma. The ESPB group showed lower resting VAS scores at 3 h postoperatively (mean [standard deviation]), 2.0 (0.5) vs 4.3 (0.7), P<0.001, and significantly lower scores at rest and during movement at 6-24 h postoperatively. The ESPB group showed lower intraoperative opioid use, lower consumption of rescue analgesia within 72 h postoperatively, and better sleep quality. ESPB subjects began to ambulate 10 h earlier than control subjects. None of the ESPB subjects showed ESPB-related complications, and analysis of a subset of subjects showed that ropivacaine concentrations in plasma decreased gradually over time. Compared with patient-controlled intravenous analgesia only, preoperative ultrasound-guided erector spinae plane block can improve postoperative analgesia, reduce opioid demand, and accelerate recovery in patients undergoing laparoscopic hepatectomy.

BACKGROUND
Laparoscopic hepatectomy is associated with trauma and severe pain. We examined whether bilateral, ultrasound-guided, single-injection erector spinae plane block (ESPB) could improve on postoperative analgesia compared with patient-controlled intravenous analgesia in patients undergoing laparoscopic hepatectomy.
METHODS
Fifty adults were randomly allocated to receive patient-controlled intravenous analgesia alone or combined with bilateral single-injection ESPB (ropivacaine 0.5%, 15 ml on each side). Primary outcome was resting pain scores at 3 h postoperatively assessed with visual analogue scale (VAS). Secondary outcomes included VAS scores at rest and during movement at 6, 12, 16, 20, 24, 48, and 72 h postoperatively; use of intraoperative opioids; postoperative rescue analgesia; sleep quality; time of first ambulation; ESPB-related complications; and ropivacaine concentration in plasma.
RESULTS
The ESPB group showed lower resting VAS scores at 3 h postoperatively (mean [standard deviation]), 2.0 (0.5) vs 4.3 (0.7), P<0.001, and significantly lower scores at rest and during movement at 6-24 h postoperatively. The ESPB group showed lower intraoperative opioid use, lower consumption of rescue analgesia within 72 h postoperatively, and better sleep quality. ESPB subjects began to ambulate 10 h earlier than control subjects. None of the ESPB subjects showed ESPB-related complications, and analysis of a subset of subjects showed that ropivacaine concentrations in plasma decreased gradually over time.
CONCLUSIONS
Compared with patient-controlled intravenous analgesia only, preoperative ultrasound-guided erector spinae plane block can improve postoperative analgesia, reduce opioid demand, and accelerate recovery in patients undergoing laparoscopic hepatectomy.
