[Selection of a method of epidural administration of drugs at the lumbosacral level].

Epidurograms made at the lumbosacral level in 200 patients were analyzed. It was ascertained that to select the optimum route of administration of drugs into the epidural space it is advisable that preliminary epidurography be performed via a low sacral puncture and the routes of contrast medium distribution be controlled. If its larger part makes its appearance parasacrally, epidural punctures should be performed at the lumbar level.
