Anaesthesia
-
An accurate, simple and safe method, based upon cadaver studies, of obtaining a thoracic paravertebral block, suitable for repeated administration by catheter or for permanent accurate neurolytic block, and which carries significant advantages over intercostal or epidural block, is described in theory and practice.

Randomized Controlled Trial Clinical Trial
Ethamsylate and blood loss in total hip replacement.
Nineteen consecutive patients undergoing total hip replacement under epidural anaesthesia were randomly divided into two groups. The treatment group received 1000 mg of ethamsylate intravenously before induction of anaesthesia. Blood lost during surgery was measured by a colorimetric technique. ⋯ Ethamsylate did not decrease the average volumes of blood lost during or after the operation. Neither did it reduce the requirements for blood transfusion. Although there were no side-effects attributable to ethamyslate, there seems to be no indication for its use in total hip replacement under epidural anaesthesia.
