Five patients who underwent thoracic operations had an extradural catheter placed in the paravertebral space. X-ray contrast was injected through the catheters. ⋯ In one patient, contrast appears to have entered the extradural space and, in another who had no detectable analgesia, the contrast was probably dispersed intrapleurally. The significance of these findings is discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Quality of axillary brachial plexus block. Comparison of success rate using perivascular and nerve stimulator techniques.
A perivascular catheter technique (PVT) and a nerve stimulator technique (NST) for axillary brachial plexus block were compared in terms of quality: complete, incomplete or failed blocks. In a randomised series, 30 PVT blocks and 30 NST blocks were performed by three staff anaesthetists. ⋯ In both groups eight patients needed supplementation with additional conduction blocks of 1-3 peripheral nerves. It is concluded that a nerve stimulator technique may increase the success rate of axillary brachial plexus block to some extent.

Case Reports[A complication of continuous blockade of the femoral nerve].
The continuous femoral nerve block is an effective method of analgesia after knee surgery. We report a case with acute compression syndrome of the femoral nerve caused by a subfascial hematoma. The symptoms developed 30 h after induction of the block. Immediate decompression brought pain relief and prevented permanent neurologic sequelae.

Comparative Study[High continuous axillary-brachial plexus anesthesia. Comparison of a new method with perivascular axillary-brachial plexus anesthesia].
High axillary brachial plexus anaesthesia was performed in 25 patients. This technique employs simple, straight forward axillary access, and produces an infraclavicular brachial plexus block which is adequate for anaesthesia of the entire arm. The technique and the equipment required are described in the text and illustrated by the figures. ⋯ The only complication that occurred was an intravenous catheter placement, which was diagnosed and corrected. No other early or late complications were observed following the use of this technique in a large group of patients. This new technique is simple and easy to master.

An adductor contraction secondary to obturator nerve stimulation can occur during transurethral resection of a lateral bladder lesion and then can induce bladder perforation or hamper complete resection. Many technique have been advocated but they are ineffective or unreliable. Obturator nerve blockade in the obturator canal by local anesthesia with control by nerve stimulator can prevent these complications. The technique described, has been used in 12 patients it is reliable, fast and easy to perform.
