Abstract:
Objective To explore the safety and feasibility of posterior quadratus lumborum block(PQLB)in patients undergoing laparoscopic myomectomy.Methods A retrospective analysis was conducted on clinical data of 62 gynecological patients who underwent laparoscopic myomectomy from July 2021 to July 2024.The patients were divided into two groups based on the preoperative blocking method:the PQLB group and the transversus abdominis plane block(TAP)group,with 31 patients in each group.In the PQLB group,bilateral PQLB was performed under ultrasound guidance with 20 ml of 0.35%ropivacaine on each side.In the TAP group,bilateral transversus abdominis plane blocks were performed under ultrasound guidance with 20 ml of 0.4%or 0.5%ropivacaine on each side.The mean arterial pressure and heart rate were recorded before anesthesia(T0),at the time of the block(T1),at skin incision(T2),and during the recovery period(T3).The local anesthetic toxicity,nerve injury,intraoperative opioid consumption,postoperative remedial analgesic usage and dosage,as well as the incidence of nausea and vomiting,were monitored.Results The operations were successfully completed in all the 62 patients.No significant differences were observed between the two groups in mean arterial pressure(F=0.323,P=0.572)and heart rate(F=0.195,P=0.660)at 4 different time points.There were no significant differences in the dosage of anesthetic analgesics during surgery(Z=-0.458,P=0.647)and length of hospital stay(Z=-1.652,P=0.099)between the two groups.The postoperative remedial analgesic usage rate in the PQLB group was significantly lower than that in the TAP group(32.3%vs.74.2%,x2=10.949,P=0.000).Within 48 h after operation,the use of non-steroidal anti-inflammatory drugs(NSAIDs)dosage in the PQLB group was significantly lower than that in the TAP group[0(0,0)mg vs.400(0,1600)mg,Z=-4.849,P=0.000],and no significant difference was observed between the two groups in the use of opioid(tramadol)dosage(Z=-0.045,P=0.964).There was no significant difference in the incidence of postoperative nausea and vomiting(P>0.05).The scores of numeric rating scale for abdomial wall pain and visceral pain in the PQLB group at 12 and 24 h after surgery did not exceed 3 points.No local anesthetic toxicity or nerve injury was observed.Conclusion PQLB provides effective analgesia for patients undergoing laparoscopic myomectomy,offering better control of visceral pain,helping reduce intraoperative opioid consumption,and lowering the risk of postoperative adverse reactions.
