Comparison of two different doses of prophylactic Norepinephrine in patients undergoing elective caesarean section to prevent post spinal Anesthesia Hypotension: A Randomised study

Prophylactic infusion of vasopressors with a rescue bolus dosing was observed to be more effective for hemodynamic stability when compared to administering bolus dose alone. With norepinephrine 0.04mcg/kg/min, there is decreased incidence(77.9%) of maternal hypotension. Still 22.1% of the patients were getting hypotension even with prophylactic norepinephrine infusion at 0.04mcg/kg/min. so we hypothetise that doubling the dose of norepinephrine prophylactic infusion can lead to 50% decrease in incidence of hypotension compared to 0.04mcg/kg/min. In this study, we compared two different doses of norepinephrine 0.04 mcg/kg/min(group A) and 0.08 mcg/kg/min(group B).
