One thousand one hundred ninety patients underwent knee arthroplasty between January 2004 and July 1, 2007, and received an indwelling continuous infusion femoral catheter for postoperative ropivicaine pump infusion. Catheters were placed using electrical stimulation guidance. For the initial 469 patients (group 1), the continuous infusion ran for 2 to 3 days. In 721 patients, the infusion was discontinued 12 hours after surgery. There were 9 femoral nerve palsies (2 in group 1, 7 in group 2) and 8 major falls (0.7%). The overall complication rate was 1.5%, and the risk of permanent nerve injury was 0.2%. Patients should be made aware of these complications as part of the usual informed consent process before using this technique for postoperative pain control after knee arthroplasty. We did not observe fewer falls when the continuous infusion was stopped 12 hours after surgery.
1190 例患者于 2004 年 1 月至 2007 年 7 月 1 日期间接受膝关节置换术，并在术后接受持续输注罗哌卡因泵输注的留置股导管。导管使用电刺激引导放置。对于最初的 469 例患者（第 1 组），连续输注持续 2 至 3 天。在 721 例患者中，术后 12 小时停止输注。共有 9 例股神经麻痹（第 1 组 2 例，第 2 组 7 例）和 8 例重大跌倒（0.7%）。总的并发症发生率为 1.5%，永久性神经损伤的风险为 0.2%。在使用该技术进行膝关节置换术后疼痛控制时，患者应该在常规知情同意过程中了解这些并发症。我们没有观察到术后 12 小时停止连续输注时跌倒次数减少。
