[Effect of intramuscular dihydroergotamine on blood circulation in the early postoperative phase. A clinical study].

The effects of Dihydergot (1,0 mg i.m.) and a placebo on orthostatic regulation disturbances were examined during the mobilisation in the first post-operative phase. According to a modified Schellong-test, 100 fresh-operated patients with hyper- rsp. hypodiastolic regulation disturbances were checked on the first post-operative day. In comparison with the placebo, Dihydergot showed a stabilisation of the systolic blood pressure and a decrease of the pulse rate during orthostatic conditions. Neither Dihydergot nor placebo influenced the diastolic blood pressure. Orthostatically caused side effects were observed less frequent within Dihydergot - therapy than under placebo.
