The Effect of Intravenous Protoveratrine on Digital Pulse Volume and Digital Skin Temperature in Hypertensive Patients
The change in digital pulse volume and skin temperature was observed after intravenous protoveratrine in 25 studies. A significant increase in the average pulse volume of the finger was noted but the range of change was large. The average change of pulse volume in the toe was not significant. A slight increase in the finger skin temperature was noted. "Vasodilatation" of the hand and feet was not the only factor resulting in a fall in blood pressure since it did not occur in all patients.
