Introduction:The study has been undertaken to determine the effect of prophylacticintravenous infusion of ephedrine in ameliorating spinal–induced hypotension

Materials and Methods: Eighty parturient scheduled for caesarean section were randomly allocated into two groups of 40 patients each: Group 1 received injection ephedrine 10 mg bolus whenever the systolic blood pressure is increased by 20% from the baseline reading. Group 2 received injection ephedrine as infusion. 50 mg was added to 500 ml lactated ringer solution

Results: It was observed that ephedrine infusion prevents early hypotension and if it occurs it is seen in lesser number of patients. Early treatment of hypotension reduces the risk of foetal depression

Conclusion:It can be concluded from this study that both the methods, bolus and infusion of ephedrine are effective in treating maternal hypotension after spinal anaesthesia for caesarean section.
