Hemodynamic Effects of Continuous Intravenous Infusion of Neo-Synephrine

Circulatory and Electrocardiographic Observations in Hypothermic Dogs treated with Phenylephrin

“…Knapp et al (10) believed that after some time phenyl ephrin given to normolhermic dogs lost its power of maintaining the BP at a high level, even when given by continuous infusion. But since the sudden drop in BP also occurred in the dogs given phenylephrin at 25°C, and at Ihe same temperature level as in the main experimental series, we do not think that this can be the explanation.…”
