Abstract: Objective:To observe the effect of ultrasoundguided suprainguinal fascia iliaca compartment block on analgesia of unilateral great saphenous vein stripping surgery.Methods:Sixty patients who underwent elective unilateral great saphenous vein stripping operation from May 2019 to September 2020 were selected and divided into two groups according to the random number table(RNT) method,30 cases in each group.The operations in both groups were completed under general anesthesia.The observation group received a single ultrasoundguided suprainguinal fascia iliaca compartment block before the induction of general anesthesia;While the control group was not treated.Patient controlled intravenous sufentanil administration was used for postoperative analgesia.VAS pain scores,PCIA compression times,cumulative sufentanil consumption,salvage analgesia and related adverse reactions were recorded at 1h,4 h,8h,24h and 48h after operation.Results:The VAS scores of the observation group at 1h,4h,8h,24h and 48h after operation was 1.5±0.9,1.6±0.9,1.8±0.9,1.5±0.8,1.3±0.8,respectively.There were all significantly lowerthan control group（3.1±0.9,3.2±0.8,2.6±0.7,2.4±0.6,2.3±0.7 ） (P<0.05).The times of PCIA pressing at 1h,4h,8h,and 24h in the observation group were 0.6±0.8,1.3±1.1,1.6±1.3,0.9±1.1,respectively,while in control group were 2.2±0.9,3.2±1.4,3.4±1.5,2.6±1.7,respectively.There were significantly difference in the two groups(P<0.05).During 48h after the operation,the cumulative sufentanil consumption in the observation group [(98.5±2.2)μg] compared with control group [(102.3±1.9)μg] was significantly difference(P<0.05).There were no significant difference in terms of the incidence of adverse reactions between the two groups(P>0.05).Conclusion:Ultrasoundguided suprainguinal fascia iliaca compartment block has a good analgesic effect for great saphenous vein stripping operation,and significantly reduces the amount of post operation opioid drugs consumption,which indicates that this block can be used as a good choice for multimode analgesia fo rgreat saphenous vein stripping surgery.
