Comparison of the Postoperative Analgesia Effect of Ultrasound-Guided Quadratus Lumborum Block and Erector Spinae Plane Block in Laparoscopic Nephrectomy
Objective:To compare the Postoperative analgesia effect of quadratus lumborum block(QLB)and erec-tor spinae plane block(ESPB)after laparoscopic nephrectomy.Methods:Sixty patients scheduled for laparoscopic ne-phrectomy under general anesthesia,were divided into two groups(n=30):quadratus lumborum block group(group Q)and erector spinae plane block group(group E).Laparoscopic nephrectomy was performed under routine general anesthe-sia,patients in group Q receive quadratus lumborum block,patients in group E receive erector spinae plane block.In-travenous controlled analgesia pump was concomitantly received in two groups.The total amount of morphine and effec-tive pressing times of 24 h were recorded.The rest visual analogue score(RVAS)and movement visual analogue score(MVAS)pain scores of patients at 2,4,8,12 and 24 h after operation were recorded.The puncture operation time,number of needle adjustments,success rate of puncture,patients'satisfaction score and adverse reactions within 24 hours after operation were recorded in both groups.Results:Compared with group E,the total amount of morphine in group Q(7.6±3.4)mg vs(12.9±4.7)mg,the effective pressing times(3.8±2.2)vs(6.2±2.6)and RVAS and MVAS scores at 2 h,4 h,6 h,8 h,12 h,24 h after operation were lower in group Q(P<0.05),and number of needle adjust-ments was lower than that in group Q(P<0.05).There was no significant difference between the two groups in the suc-cess rate of puncture(P>0.05).There was no statistical difference between the two groups in adverse reactions within 24 hours after operation(P>0.05).The patients'satisfaction score in group Q was higher than that in group E(P<0.05).Conclusion:Compared with ESPB,QLB had more significant analgesic effect,while ESPB had lower number of needle adjustments and shorter puncture time,which was beneficial to clinical operation implementation.
