SHOCK CAUSED BY CONTINUOUS INFUSION OF METARAMINOL BITARTRATE (ARAMINE).

Abstract

Increasing doses of metaraminol bitartrate (Aramine) in a continuous intravenous infusion were used to support the blood pressure in four patients. Under such treatment a state of shock developed, characterized by intense peripheral vasoconstriction, hypotension and anuria. In spite of an adequate fluid intake all patients showed severe hemoconcentration, and a critically low plasma volume could be demonstrated in two. While metaraminol (Aramine) was ineffective, noradrenaline still caused a moderate blood pressure response. Treatment with plasma expanders (Intradex) and small doses of noradrenaline (Levophed) resulted in transient improvement in one patient and complete recovery from shock in three. The peripheral vasoconstriction persisted up to 12 hours and renal function improved on the second day after the withdrawal of metaraminol. The etiology of this shock syndrome is believed to be similar to that of experimental shock produced with adrenaline and noradrenaline.
