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.

Comparative StudyDistance from skin to the lumbar epidural space in an obstetric population.
The distance from skin to the epidural space was measured in 163 patients receiving epidural analgesia. The mean distance was found to be 4.78 cm, which correlated with other anatomic measurements. The presence of edema and the ethnic origin of the patients had significant effects on this distance.
