Background and Goals: Research suggests that perineural local anaesthetic infusion is generally well tolerated by ambulatory patients (1). The aim of this case series was to evaluate the effectiveness of regional analgesia using a sciatic popliteal perineural catheter and portable infusion pump in ambulatory patients, undergoing foot surgery.
Material and Methods: Preoperatively 20 patients received a sciatic nerve block and perineural catheter in the popliteal fossa. After surgery, the plexus catheter was conected to a disposable elastomeric infusion pump containing 100 mls of ropivacaine 0.2% infusing at a rate of 2 mls per hour. Patients were contacted by telephone on days 0, 1 and 2. Scores were recorded for pain: VAS (0-10), satisfaction: (Yes/Neutral/No) and motor function normal: (Yes/No). Difficulty and pain during catheter removal was also recorded.
No patients reported difficulties with catheter removal. 100% would recommend the technique.
Conclusions: Continuous perineural local anaesthetic infusion pumps provide effective analgesia with a high patient satisfaction score in patients after ambulatory foot surgery.
