Verapamil as a hypotensive agent under general anaesthesia
1Department of Anaesthesiology, JN Medical College, Aligarh Muslim University.
Thirty-six adult female patients undergoing abdominal hysterectomy under general anaesthesia were evaluated for the haemodynamic effects of IV verapamil in bolus dose of either 50 micrograms/kg (group A), 60 micrograms/kg (group B) or 75 micrograms/kg (group C). The result showed a dose dependent fall in the mean arterial pressure and increase in the P-R interval. The fall in heart rate was marginally more in group A and B as compared to group C.
