Background: Maternal hypotension due to spinal anaesthesia in caesarean section is commonly seen. Alongwith fluid loading, phenylephrine is used to manage the hypotension. However, this drug is associated with cardiovascular side effects. Methods: This is a prospective double blinded study which was conducted on 100 term parturients scheduled from elective caesarean section under spinal anaesthesia, randomly assigned into two groups. After spinal anaesthesia patients of group N and P were treated with norepinephrine (5mcg) and phenylephrine (50mcg) respectively as an IV bolus for hypotension. Blood pressure, heart rate, number of bolus doses given, and neonatal APGAR score was noted. Results:  Patients of both groups were comparable with respect to haemodynamic parameters (HR, SBP, DBP, AND MAP). Incidence of bradycardia was higher in group P (22%, n=11) compared to group N (14%, n=7). Neonatal APGAR scores at different time intervals were similar in both groups. Conclusion: Intermittent boluses of norepinephrine were effective in the treatment of spinal anaesthesia induced hypotension during caesarean section and can be considered as an alternative to phenylephrine.

This study was designed to determine the minimum effective dose (ED50) of mephentermine for prevention of post-spinal hypotension in women undergoing elective caesarean section. Dixon's up-down method of sequential allocation was used to determine the patient's dose of vasopressor drug. In our previous study, mephentermine appeared to be much more potent than ephedrine, so the present study was conducted using a lower initial dose and smaller dose interval for this vasopressor. Following administration of spinal anaesthesia, a prophylactic infusion of mephentermine was started with 5 mg infused over a period of 30 minutes as the initial dose and a dose interval of 1 mg. The ED50 of mephentermine of 3.7 mg (95% confidence interval 2.4 to 5.7 mg) was much less than that of ephedrine, as calculated in our previous study using the same methodology. Using these values gives a potency ratio of ephedrine to mephentermine of 1:6.8 (95% confidence interval 6.0 to 7.5).
