Background: Due to anesthetic blockage up to the T4 level, 80% of parturients after caesarean section (CS) have been observed to experience spinal anaesthesia induced hypotension (SAIH). The present study compared intravenous norepinephrine and mephentermine for maintenance of blood pressure during spinal anaesthesia for caesarean section. Materials &Methods:56 parturients selected for elective caesarean section (CS) under subarachnoid block (SAB)were split into two groups of 28 each. For SAIH, group I subjects got intravenous boluses of 8 µg norepinephrine, while group II subjects received 6 mg Mephentermine. In both groups, parameters like Apgar score, systolic and diastolic blood pressure, and side effects were noted and compared. Results:The mean age in group I subject was 23.5 years and in group II was 25.6 years, height was 160.2 cm in group I and 163.5 cm in group II, weight was 62.7 kgs in group I and 64.8 kgs in group II, duration of surgery was 49.3 minutes in group I and 46.2 minutes in group II, APGAR score at 1st minute was 7.35 in group I and 7.41 in group II and at 5 minutes was 9.08 in group I and 9.02 in group II. The difference was non- significant (P> 0.05). There was a non- significant difference in change in systolic and diastolic blood pressure in both groups (P> 0.05). The number of requirement of doses were 1 time seen in 5 in group I and 11 in group II, 2 times seen 12 in group I and 7 in group II, 3 times seen 6 in group I and 5 in group II, 4 times seen 3 in group I and 3 in group II, 5 times seen in 1 in group I and 2 in group II and 6 times seen 1 subject in group I and group II each. The difference was significant (P< 0.05). Conclusion:When it came to blood pressure maintenance during spinal anesthesia for caesarean sections, intravenous norepinephrine and mephentermine were comparable.
