Abstract
Objective:To explore the efficacy of continuous saphenous nerve block(SNB)with sufentail used for postoperative analgesia after knee arthroscopic surgery.Methods:Eighty patients underwent selective knee arthro-scopic surgery,received postperative analgesia wit continuous nerve block for 48 hours,continuous dose 2 ml/h,totle dose 100 ml,then were randomly divided into four groups:femoral nerve block group with 0.225% ropivacaine (group F);femoral nerve block group with 0.15% ropivacaine mixed sufentanil 1μg/ml(groupFD);saphenous nerve block group with 0.225% ropivacaine(group S);saphenous nerve block group with 0.15% ropivacaine mixed sufentanil 1ug/ml(group SD).The visual analogue scale(VAS)in resting state(RVAS),active functional exercise state(AVAS)were recorded at pre-operation and 24,48,72 h,7 d after surgery.The quadriceps muscle strength was recorded at 12,24,36,48 h after surgery.Results:Compared with preoperative situation,the pain scores at rest in each group were significantly decreased on every time after surgery,the AVAS scores were sigificantly lower at 24h, 48h,7d after surgery(P<0.05).Compared with group F and group D,the RVAS scores were significantly higher ei-ther in group FD and group SD at the 3d postoperativly(P<0.05).the quadriceps muscle strength at 24,36,48 h in the group S and group SD was higher than that in the group F and group FD.Conclusion:Both SNB and FNB can of-fer effective analgesic results after knee arthroscopic surgery,but SNB has less influence on quadriceps muscle strength than FNB.Compared to 0.225% ropivacaine,0.15% ropivacaine mixed 1μg/ml sufentanil may not keep a longer anlgesia duration.关键词
