Abstract：Objective To investigate the effect of ultrasound-guided lumbar quadratus block on postoperative analgesia,inflammatory stress,and immune function in patients undergoing hip arthroplasty.Methods 128 patients who underwent hip arthroplasty in our hospital from January 2022 to December 2022 were divided into the general anesthesia group ( n=64 ) and the block group ( n=64 ) using the random number table method.The degree of postoperative pain,anesthetic effect,inflammation and stress reaction indexes[serum interleukin-6 ( IL-6 ),C-reactive protein ( CRP ),cortisol ( Cor )],and adverse reactions were compared between the two groups.Results The differences in postoperative pain degree,inflammation and stress response indicators,and immune function indicators between groups,time,and interactions were statistically significant ( P<0.05 ) .The VAS scores at 6h,12h,and 24h after surgery,IL-6,CRP,and Cor levels first increased and then decreased,and the VAS scores,the number of postoperative rescue analgesia,and IL-6,CRP,Cor levels in the block group were all lower than those in the general anesthesia group ( P<0.05 ) .The total incidence rate of adverse reactions in the block group was 9.38％,which was lower than 23.44％ in the general anesthesia group ( P<0.05 ) .Conclusion Ultrasound-guided lumbar quadratus block can effectively reduce postoperative pain,inflammation,and stress response levels after hip arthroplasty,with good anesthetic effects and safety.
