Effect Analysis of Ultrasound-guided High Iliac Fascia Block Combined with Popliteal Sciatic Nerve Block for Varicose Vein Surgery of Lower Extremity
Objective To explore the clinical anesthesia effect of ultrasound-guided high fascia iliaca block(FIB)combined with popliteal sciatic nerve block(PSNB)in varicose vein surgery of lower extremity.Methods From June 2022 to November 2023,64 patients who underwent varicose vein surgery in Yudu County People's Hospital were randomly divided into control group(32patients)and observation group(32 patients).The control group received epidural anesthesia,while the observation group received ultrasound-guided high FIB combined with PSNB anesthesia.The block completion time,block onset time,anesthesia effect,hemodynamic indexes[mean arterial pressure(MAP),heart rate(HR)],postoperative analgesic effect[Visual Analogue Scale(VAS)]and adverse reactions of anesthesia were compared between the two groups.Results There was no significant difference in the completion time of block between the two groups(P>0.05).The onset time of block in the observation group was shorter than that in the control group(P<0.05).The excellent and good rate of anesthesia in the observation group was higher than that in the control group(P<0.05).Compared with before block(T0),the MAP and HR of the two groups decreased at 20 min(T1),40 min(T2)after block and at the end of operation(T3),but the MAP and HR of the observation group at T1,T2 and T3 were higher than those of the control group(P<0.05).The postoperative VAS score(static and dynamic)of the observation group was lower than that of the control group(P<0.05).The incidence of adverse reactions of anesthesia in the observation group was lower than that in the control group(P<0.05).Conclusion Ultrasound-guided high FIB combined with PSNB has a good anesthetic effect in varicose vein surgery of lower extremity,and the block takes effect quickly,has little effect on hemodynamics,has good postoperative analgesic effect and less adverse reactions of anesthesia,which is worthy of application.
