Randomized Controlled Trial Clinical Trial
An evaluation of intercostal nerve blockade for analgesia following renal transplantation.
In a double-blinded study we examined the effect of supplementing patient-controlled morphine analgesia with intercostal nerve blockade to identify if this improved analgesia and reduced morphine requirements following renal transplantation. Fifty patients were randomized to receive unilateral intercostal nerve block with either 0.5% bupivacaine or saline to the lower five intercostal nerves. ⋯ Two patients developed a pneumothorax, neither of which were clinically apparent at the time of diagnosis, and only detected by chest radiography. A chest radiograph should therefore be considered mandatory after intercostal nerve blockade.

Clinical Trial Controlled Clinical Trial
[Vertical infraclavicular brachial-plexus blockade. A clinical study of reliability of a new method for plexus anesthesia of the upper extremity].
We examined the efficacy of the vertical infraclavicular block for plexus brachialis anaesthesia using a nerve stimulator after introducing the method (VIP1) and after three years of clinical experience (VIP2). In two prospective studies we compared the results with each other as well as with the efficacy of the axillary block (AX). At VIP1, we found a complete analgesia in 88% of the patients, whereas in 9% a supplementation was needed. ⋯ In general, the results of the VIP depended on the motoric answer to the nerve stimulation. There were no complications of the VIP such as nerve lesions or pneumothorax. The VIP using a nerve stimulator is a simple, reliable and uncomplicated method for plexus-brachialis-anaesthesia, which is easy to learn.

Clinical TrialNerve blocks with 5% butamben suspension for the treatment of chronic pain syndromes.
Butamben is a non-water-soluble local anesthetic that can be prepared as an aqueous suspension for nerve blocks. This report describes the use of 5% butamben suspension for the treatment of chronic pain of cancer and noncancer origin. ⋯ When used as described in this report, 5% butamben suspension appears to be effective for treatment of chronic pain of both cancer and noncancer origin and has a low incidence of adverse sequelae.
