BACKGROUND AND OBJECTIVES: Postoperative analgesia is crucial for early functional excise after total knee arthroplasty. To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral @entity616 analgesia after total knee arthroplasty. METHODS: 46 @entity1 with ASA grade I-III who underwent total knee arthroplasty received postoperative analgesia from October 2012 to January 2013. In 22 @entity1 , ultrasound and nerve stimulator guided continuous femoral @entity616 were performed for analgesia (CFNB group); in 24 @entity1 , epidural analgesia was done (PCEA group). The analgesic effects, side effects, articular recovery and complications were compared between two groups. RESULTS: At 6h and 12h after surgery, the knee @entity158 score (VAS score) during functional tests after active exercise and after passive excise in CFNB were significantly reduced when compared with PCEA group. The amount of @entity14340 used in CFNB @entity1 was significantly reduced when compared with PCEA group. At 48h after surgery, the muscle strength grade in CFNB group was significantly higher, and the time to ambulatory activity was shorter than those in PCEA group. The incidence of @entity1209 in CFNB @entity1 was significantly reduced when compared with PCEA group. CONCLUSION: Ultrasound and nerve stimulator guided continuous femoral @entity616 provide better analgesia at 6h and 12h, demonstrated by RVAS and PVAS. The amount of @entity14340 also reduces, the incidence of @entity1209 decreased, the influence on muscle strength is compromised and @entity1 can perform ambulatory activity under this condition.
