Journal of the Indian Medical Association. 1990 Sep; 88(9): 251-3http://imsear.searo.who.int/handle/123456789/101485Thirty-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.engAdultAnesthesia, GeneralBlood Pressure --drug effectsElectrocardiography --drug effectsFemaleHeart Rate --drug effectsHumansHypotension, ControlledHysterectomyMiddle AgedVerapamil --administration & dosageJournal Article
