Objective To observe the effect of erector spinae plane block (ESPB) on the quality of recovery (QoR) in obese patients undergoing sleeve gastrectomy.
Methods Ninty-eight patients undergoing laparoscopic sleeve gastrectomy, 9 males and 89 females, aged 18-64 years, BMI ≥28 kg/m2, ASA physical status Ⅱ or Ⅲ, were randomly divided into two groups: ESPB group (group E, n = 50) and control group (group C, n = 48). The patients in group E received ultrasound-guide before general anesthesia, with 0.33% ropivacaine 30 ml per side. The 15-item quality of recovery questionnaire (QoR-15) was evaluated preoperatively and postoperative 24 and 48 hours. Self-reported VAS scores at rest and on movement were recorded 0.5, 2, 6, 12, 24 and 48 hours after operation. The number of analgesic pump pressings, the cumulative consumption of postoperative analgesics and the rate of rescue analgesia were recorded within 48 hours after the operation. The incidence of dizziness, postoperative nausea or vomiting (PONV), respiratory complications and nerve block related complications were also recorded. Moreover, postanesthesia care unit (PACU) discharge time, postoperative activity time, intestinal exhaust time and the length of hospital stay were recorded.
Results There were no significant differences in QoR-15 overall scores between the two groups 24 and 48 hours after operation. Compared with group C, group E reduced VAS scores on movement 12 hours after operation (P < 0.05), and there was no significant difference in VAS pain score between the two groups at the rest of the time. There was no significant difference in the number of times of analgesia pump pressing, cumulative consumption of analgesics and rescue analgesia rate within 48 hours after operation between the two groups. There were no significant differences in postoperative dizziness, postoperative nausea or vomiting, respiratory complications, PACU discharge time, postoperative activity time, intestinal exhaust time and length of hospital stay between the two groups.
Conclusion Although single erector spinal block did not significantly improve the recovery quality after laparoscopic sleeve gastrectomy, it could enhance the analgesic effect. |
