[The effects of dihydroergotamine on volume content and compliance of the extrathoracic capacitance vessels of man under anesthesia during extracorporeal circulation in hypothermia (author's transl)].
The influence of dihydroergotamine on volume content and compliance of the extrathoracic capacitance vessels during extracorporeal circulation was investigated. Compared with an untreated control group the compliance decreased (0.44 ml/mm Hg/kg b. wt.) and 490 ml of blood was mobilized and shifted from the circulation into the blood reservoir of the machine. Therefore DHE counteracts the effects of venous pooling.
