Abstract：Objective:To compare the advantages and disadvantages of three concentrations of ropivacaine for iliofascial gap block in general anesthesia for hip surgery in the elderly,in order to provide a reference for clinical application.Methods:120 pa-tients who underwent hip surgery in the hospital from January to December 2019 were selected and randomly divided into A,B,C,groups,with 40 cases in each group.0.250%,0.375%and 0.500%ropivacaine was used in groups A(0.25%),B(0.375%),and C(0.5%)for iliac fascia gap block(FICB)combined with general anesthesia,respectively.The opioid dosage,analgesic effect and mo-tor function at 6 h,12 h and 24 h postoperatively,postoperative nausea and vomiting response and rehabilitation compliance of the three groups were compared.Results:The motor pain scores at 6 h,12 h,and 24 h postoperatively were lower in groups B and C than in group A,and the motor pain at 24 h postoperatively was lower in group C than in group B,and the differences were statisti-cally significant(F=2.330,1.769,2.232;9.481,8.222,3.953;3.953,4.783,4.866;5.214,4.731,3.827,P＜0.05).The degree of nausea and vomiting within 24 h after surgery was higher in group A than in groups B and C.The compliance and comfort of reha-bilitation were lower than in groups B and C,and the differences were statistically significant(F=11.905,6.395,12.405,P＜0.05).Conclusion:FICB with 0.375%ropivacaine for general anesthesia of the hip in the elderly is effective in analgesia,with less nau-sea and vomiting and better postoperative motor function.
