[Use of a caudal epidural sympathetic nerve block and a combination injection in chronic arterial circulatory disorders of the lower extremities].

In 30 patients with organic disturbances of the arterial blood supply of the lower extremities the caudal epidural combination injection (one per cent procaine and radecol comp.) in comparison to the caudal epidural sympathetic blocking one per cent procaine) was performed. By means of experiments on corpses of adults the spreading of the anaesthetic drug (in form of a model imitated by one per cent methylene blue) into the thoracic epidural space could be proved. The method was objectified according to clinical and plethysmographic points of view. A particular indication is present in the ischaemic ulcer depending on arteriosclerosis. During the plethysmographic investigations clear differences appeared in favour of the caudal epidural combination injection.
