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.

Comparative Study Clinical Trial[0.75% and 0.5% bupivacaine in peridural lumbar block for surgery on the lower abdomen; a double-blind comparison and myographic study].
A double blind study has been carried out on 40 patients subjected to peridural block with 0.50% and 0.75% bupivacaine for operations on the low abdomen. While no significant differences were observed with regard to the latency and duration of anaesthetic action, 0.75% marcaine was more effective as regards the duration and degree of motor block. This result was also confirmed by an electromyographic study of the muscles of the hypothenar eminence.
