Randomized Controlled Trial Clinical TrialOptimal regional anesthesia for circumcision.
Dorsal penile nerve block (DPNB) is a useful procedure for analgesia in circumcision. It has minor complications and a reported failure rate of from 4% to 6.7%. To evaluate the intraoperative value of additional anesthesia of the perineal nerves--a branch of the pudendal nerve--during circumcision, we conducted a prospective randomized double-blind study on 250 adults. ⋯ On the other hand, only six patients (4%) in Group II had a mild diffused discomfort with no need for additional local anesthesia (P < 0.01). The average operating time was 12.4 +/- 2.7 min (range 9-22 min) in Group I and 10.7 +/- 1.6 min (range 8-15 min) in Group II (P < 0.001). We think that perineal nerves play an important part in innervation of the penis and must be anesthetized during the penile block.

Clinical TrialOne needle transcrural celiac plexus block. Single shot or continuous technique, or both.
The purpose of the study was to establish a one needle transcrural technique for the celiac plexus block in the lateral position. Contrary to the conventional prone bilateral approach, the lateral position with a cushion under the flank is better tolerated and makes bony landmarks more accessible. Unilateral needle placement reduces the morbidity of the technique and should also enable one to apply single administration or continuous blocks, or both. ⋯ Clinical results proved that the unilateral, transcrural technique in a lateral position is simple, safe, and gives a reliable celiac plexus block or neurolysis effects under fluoroscopy, or both, comparable to the results where computed tomography was used. The possibility of continuous block makes this technique useful in clinical practice.

Randomized Controlled Trial Clinical TrialInterscalene block for pain relief after shoulder surgery. A prospective randomized study.
A prospective randomized study undertaken in 30 patients who underwent outpatient decompressive acromioplasty demonstrated the efficacy and safety of interscalene block post-operatively. Interscalene block improved the postoperative condition and well being of these patients. Their use decreased the hospitalization rate. There were no complications or side effects.

The use of epidural analgesia has become so widespread in recent years that many women are now requesting repeat epidural analgesia for their second or subsequent labour. This study examines the incidence of problems at insertion and of inadequate block in 71 multiparae having second epidurals compared with 150 primiparae having their first epidural. ⋯ Epidurals were inserted at a greater dilatation (P < 0.05) and there was a shorter time to delivery (P < 0.01) in the multiparous group. We conclude that unilateral block is thus more common in women receiving repeat epidurals.

A technique for blocking the brachial plexus using a electrostimulator and conventional, non-special plastic cannula with an obtulator consist of conductive metal is described. This cannula is cheaper and more conventional than special plastic-coated needle. Brachial plexus block is useful anesthesia for surgical treatment of fractures, dislocations, skin and muscle injuries of the forearm and hand. ⋯ Therefore the method using an electrostimulator and a special plastic-coated needle for the brachial plexus block was reported in 1962 by Greenblatt. Employing a conventional plastic cannula for intravenous use instead of a special plastic-coated needle reported by Greenblatt. We could attain nerve block completely reliably, safely and easily.
