Assessment of block of the sciatic nerve in the popliteal fossa.
Success of block of the sciatic nerve in the popliteal fossa in 130 patients was assessed by an anesthesiologist at the time of surgery. The patients were evaluated for complications by the anesthesiologist during postoperative rounds and by the orthopedic surgeon at the 1-month follow-up visit. Acceptance of the block by the patient was judged by answers on a questionnaire filled out by the patients after they had gone home. ⋯ Two patients described sensations compatible with postoperative paresthesias, and two others described sensations that may have been paresthesias; in none did the sensations last longer than 1 month. Assessment of the blocks by the anesthesiologist in all 130 patients in the study revealed that anesthesia satisfactory for completion of the operative procedure was achieved in 107 (82.3%). General anesthesia was needed in eight patients (6.2%), and in 15 patients (11.5%) intravenous sedation or injection of the site of surgical incision with local anesthesia (or both) was needed.

Randomized Controlled Trial Comparative Study Clinical Trial
The neonatal neurobehavioral effects of bupivacaine, mepivacaine, and 2-chloroprocaine used for pudendal block.
The neonatal neurobehavioral effects of bupivacaine, mepivacaine, and 2-chloroprocaine used in random sequence for pudendal block anesthesia were studied. The neurobehavioral status of 54 infants was studied 4 and 24 hours after delivery. ⋯ Mean mepivacaine levels in neonatal capillary blood at 4 hours of age were low (0.10 +/- .02 microgram/ml) compared with those in previous studies because of the short interval between maternal injection and delivery (13 +/- 3 min). Bupivacaine gave higher neonatal capillary blood levels (0.15 microgram/ml at 4 hours of age) than previously reported, but the drug still produced no detectable neonatal neurobehavioral effects.
