Comparative Study[Pharmacodynamics of propofol in children and adults: comparison based on the auditory evoked potentials index].
The clinically useful concentrations of propofol to provide loss of consciousness in children have not been determined. Therefore, target-controlled infusion systems are used with parameters taken from results for adults. As a result, hypnosis can be inadequate in the pediatric population. We studied the dose-response relationship by comparing the predicted effect-site concentration (Ce) and the level of hypnosis measured by a monitor of depth of anesthesia based on auditory evoked potentials. ⋯ Children seem to be more sensitive to propofol than adults, suggesting that the higher dose requirements described for children would be attributable to pharmacokinetic differences between the 2 populations.

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.

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.
