Brief Summary  
Study Title: Comparative efficacy of prophylactic intravenous dexamethasone and mephentermine versus mephentermine alone on the incidence of spinal anaesthesia mediated hypotension in parturients undergoing caesarean
section

Study Type: Double blind randomised controlled study

Objective: To compare efficacy of prophylactic intravenous dexamethasone and mephentermine versus mephentermine alone on the incidence of spinal anaesthesia mediated hypotension in parturients undergoing caesarean section.

Participants: Pregnant women of age 18 to 35 years, ASA PS II,singleton pregnancy with gestational age more than 37 weeks scheduled for elective cesarean delivery under spinal anaesthesia will be included in the study

Interventions:

Group A: Patients will receive intravenous dexamethasone 8mg in 10 ml saline over 1 minute in preoperative area 15 minutes prior to subarachnoid block
Group B: Patients will receive intravenous10 ml normal saline over 1 minute in pre operative area 15 minutes prior to subarachnoid block

Primary Outcome: To evaluate and compare the incidence of spinal anaesthesia mediated hypotension in parturients undergoing caesarean section in patients receiving intravenous dexamethasone and mephentermine versus mephentermine alone till 20 min after spinal anaesthesia

Secondary Outcomes:

To evaluate and compare
Haemodynamic parameters like heart rate and systolic blood pressure at
baseline, every 2 minutes till 20 minutes after spinal anaesthesia and then
at every 5 minute interval till the end of surgery.
Time to achieve T6 level of block
Total dose of mephentermine(mg) administered
Time to first rescue mephentermine bolus
Neonatal Apgar score at 1 minute and 5 minutes 

Sample Size:  170 patients (85 per group) .
