Preoperative percutaneous ilioinguinal and iliohypogastric nerve block with 0.5% bupivacaine for post-herniorrhaphy pain management in adults.
The safety, effectiveness and duration of a percutaneous ilioinguinal-iliohypogastric nerve block with 10 ml 0.5% bupivacaine, as a method for postoperative analgesia, were studied prospectively in adult patients undergoing unilateral inguinal herniorrhaphy under spinal anesthesia. Group I (n = 20) blocked patients were compared with Group II (n = 25), non-blocked control patients. ⋯ Group I patients had less pain at 3, 6, 24 and 48 hours after surgery and also required less analgesics during the first two postoperative days. This technique appears to be a simple and safe method for providing effective and long-lasting postoperative analgesia following inguinal hernia repair in adults.

Randomized Controlled Trial Clinical TrialLocal anesthetic efficacy of ropivacaine (LEA 103) in ulnar nerve block.
Ropivacaine (LEA 103) is a new long-acting local anesthetic that in animal experiments has proved to be equally potent but less toxic than bupivacaine. In this controlled double-blind study in man, the dose-response relation of ropivacaine was examined in peripheral nerve block and its potency was compared to that of bupivacaine. Nerve functions during bilateral ulnar nerve block were monitored in 70 normal subjects by a computer-controlled method. ⋯ Its profile of action is uniform for the different fiber groups and resembles that of bupivacaine. Addition of epinephrine does not improve latency or duration of ropivacaine nerve block. Adverse effects attributable to ropivacaine have not been observed.

Randomized Controlled Trial Comparative Study Clinical TrialAnesthesia for neonatal circumcision: local anesthesia is better than dorsal penile nerve block.
Several studies document the benefit of dorsal penile nerve block for neonatal circumcision, but the literature does not address the use of local anesthesia. A randomized, controlled, prospective study was conducted to compare the efficacy of dorsal penile nerve block versus local anesthesia. Thirty infants were randomly divided into three equal groups (N = 10): an unanesthetized control group, a group given dorsal penile nerve block, and a group given local anesthesia. ⋯ Dorsal penile nerve block had no effect on postoperative cortisol levels. No complications occurred. Although both types of anesthesia attenuated the physiologic responses to circumcision, local anesthesia demonstrated greater efficacy than dorsal penile nerve block while being simpler to perform.

Carotid endarterectomy under cervical plexus block--a prospective clinical audit.
One hundred and twenty-eight patients having carotid endarterectomy under superficial and deep cervical plexus blocks were prospectively audited. The aim of the audit was to determine the incidence of intra-operative and postoperative neurological and cardiovascular complications and to establish patient acceptance of the technique. Twenty-seven patients who had intra-operative neurological changes following carotid artery clamping responded to shunt insertion. ⋯ Tachycardia (55%) and hypertension (67%) were the most common intra-operative cardiovascular changes and there was one clinical postoperative myocardial infarction. Ninety-two per cent of patients who could be adequately assessed preferred to have the same method of anaesthesia for future carotid endarterectomy. The authors concluded that carotid endarterectomy under superficial and deep cervical plexus blocks was associated with a high patient acceptance, low neurological complication rate and an acceptable rate of cardiovascular complications.
