Effect of quadratus lumborum block on postoperative analgesia in cesarean section under general anesthesia / 中国医师杂志

ABSTRACT

Objective To observe the analgesic effect of quadratus lumborum block (QLB) in cesarean section under general anesthesia.Methods 50 patients underwent cesarean section under general anesthesia were randomly divided into two groups (n =25)patients in QLB group (group Q) received QLB at the end of surgery with 0.3％ ropivacaine 25ml,and the control group (group C) patients were disinfected at the same site but did not puncture.The visual analogue scale (VAS) and pain Bruggrmann comfort score (BCS) were recorded at 2,6,12,24,and 48 hours after surgery.The patient's general condition,vital signs and postoperative analgesia-related adverse reactions were recorded.Results There were no significant differences between the two groups in general information and surgical related indexes (P ＞ 0.05).The VAS scores of the Q group were lower than the control group at 2,6,12 and 24 hours,and the BCS score was higher than that in the control group (P ＜ 0.05).There was no difference in VAS score,BCS score after 48 hours,and no difference in adverse reaction rate between the two groups (P ＞ 0.05).Conclusions Quadratus lumborum block combined with intravenous analgesia can reduce the pain score within 24 hours after cesarean section under general anesthesia and improve postoperative analgesia comfort.
