Analysis of Anesthetic Effect of Modified Ultrasound-Guided"Cloverleaf Method"Lumbar Plexus Block in Patients Undergoing Unilateral Lower Limb Surgery
Objective:To observe the anesthetic effect of modified ultrasound-guided"cloverleaf method"lumbar plexus block in patients undergoing unilateral lower limb surgery.Methods:According to the random number table method,86 patients with unilateral lower limb surgery who were admitted to our hospital from December 2020 to March 2023 were divided into group A(n=43)and group B(n=43).Group A received ultrasound-guided"Trident"LPB technology,and group B received modified ultrasound-guided"cloverleaf method"positioning.The success rate of one-time nerve block,the number of times to adjust the direction of the puncture needle,the po-sitioning time,puncture time,excellent rate of anesthesia,visual analogue scale(VAS)of pain were compared between two groups,and the adverse reactions during the treatment were observed.Results:The success rate of one-time nerve block in group B was higher than that in group A,the number of times to adjust the direction of the puncture needle was less than that in group A,and the positioning time and puncture time were shorter than those in group A(P＜0.05).The excellent rate of anesthesia in group B was higher than that in group A(P＜0.05).The VAS scores in group B at 6 h,12 h and 24 h after operation were lower than those in group A(P＜0.05).There was no difference in the incidence of adverse reactions between two groups(P＞0.05).Conclusion:Compare with the application of ultra-sound-guided"Trident"LPB technology in patients undergoing unilateral lower limb surgery,the improved ultrasound-guided"cloverleaf method"positioning can shorten the positioning time and puncture time,reduce the the number of times to adjust the direc-tion of the puncture needle,reduce postoperative pain,and improve the anesthetic effect.
