Randomized Controlled Trial Comparative Study[Oral analgesia versus posterior tibial nerve block for postoperative pain in ambulatory open hallux valgus surgery: a randomized clinical trial].
This trial assessed the safety and efficacy of a continuous posterior tibial nerve block in the ankle provided in the patient's home by elastomeric pump infusion of 0.375% ropivacaine after ambulatory hallux valgus surgery. ⋯ Continuous perineural analgesia in the home setting was found to be effective and safe in our patients.

Review[Techniques to block the sciatic nerve by a lateral approach through the popliteal fossa].
Lateral approaches to the sciatic nerve through the popliteal fossa have recently been described as useful for providing adequate anesthesia and postoperative analgesia for foot and ankle surgery. Numerous publications have appeared on the approach in recent years, proposing new anatomical landmarks to facilitate location of the nerve, reduce the rate of complications, and increase the rate of success. ⋯ This review describes the lateral popliteal approach, its main variations, the factors that can affect latency time or success, and the possibility of providing continuous analgesia. We also sought to compare this approach to other techniques for blocking the sciatic nerve.

Recent years have brought renewed interest in peripheral nerve blocks as new drugs and materials have become available and as the advantages of such blocks over other anesthetic and analgesic techniques have been demonstrated. We conducted a literature search in PubMed, the Cochrane Library Plus (Spanish version), and Healthgate for the period January 1, 2000 through October 15, 2005 using the key words "complication and peripheral nerve block," "complication and peripheral block anaesthesia," and "complication and plexus anaesthesia." Totals of 178, 109, and 145 titles were obtained with each portal. When the search was limited to reviews, clinical trials, and randomized controlled trials, the numbers of articles from each portal became 11, 20, and 10, respectively, for the first string of key words; 0, 8 and 6, respectively, for the second string; and 10, 40 and 16 for the third. ⋯ Most of these publications agree that the overall incidence of complications related to these techniques is low. If practice guidelines and algorithms from experts are followed the incidence can be reduced. The aim of this review is to give an updated report of complications related to peripheral nerve blocks.
