Comparison of the Application of IPACK Block and LIA in Knee Arthroplasty
Objective:To compare the analgesic effect of IPACK and LIA for knee arthroplasty.Methods:60 patients scheduled for knee arthroplasty were randomly divided into two groups:Group I and Group L.IPACK was performed in Group I,and LIA was performed in Group L.Pain score,patient satisfaction,the maximum range of knee motion,the number of ambulatory steps,analgesic remedy and adverse events were recorded.Results:Through comparing with Group L,static pain score of Group I at 8 h(T2)decreased,with statistically significant difference(Z=-2.171,P＜0.05).Through comparing with Group L,dynamic pain score of I group at T2 and 24 h(T3)decreased,with statisticall significant difference(Z=-1.277,-2.841;P＜0.05).Through comparing with Group L,Oxycodone of Group I decreased significantly,with statistically significant difference(x2=6.667,P＜0.05).Through comparing with Group L,the maximum range of knee motion 2～3 days after operation was increased in Group I,with statistically significant difference(Z=-2.088,-2.426;P＜0.05).Conclusion:IPACK block might be more suitable for postoperative analgesia than LIA for knee arthroplasty.
