The effect of drug therapy without volume replacement in experimental traumatic shock. Part I. Phenoxybenzamine and dopamine.

The effect of phenoxybenzamine and dopamine on the respiratory and metabolic changes in experimental traumatic shock was examined in 45 rabbits. Phenoxybenzamine caused a more effective release of the peripheral vasoconstriction than dopamine. The effect of these drugs without similar restoration of blood volume was unfavourable. This should be borne in mind when the use of these drugs is meditated in clinical work.
