Dopamine hydrochloride (Intropin) and open-heart surgery: results of a clinical trial

Dopamine hydrochloride (Intropin) has been used in the postoperative management of open-heart surgical patients, both children and adults. It has been associated with a very low incidence of undesirable responses and a high frequency of circulatory improvement associated with diuresis. Its administration requires careful control of infusion rate and measurement of response. In the dosages employed, it has been free of most of the undesirable side effects of other commonly used catecholamines.
