Introduction: Hypotension and bradycardia following the administration of spinal anesthesia for cesarean section are very common and bear profound detrimental effects both on mother and baby. In our country, a significant proportion of patients undergo cesarean section delivery. Considering the workload and the socio-economic condition it is often a bad headache for our anesthesiologists to combat post-spinal hypotension. Vasopressor drugs have been widely used to prevent and treat maternal hypotension during cesarean section under spinal anesthesia. A combination of preloading and using vasopressor has maximum efficacy in preventing spinal-induced hypotension but with compromising with some detrimental adverse effects of vasopressor. Amongst vasopressors, ephedrine is widely used but studies found that a higher bolus dose is often required to prevent hypotension and bradycardia. Aim of the study: To find out the efficacy of ondansetron to prevent haemodynamic derrangement in cesarean section under spinal anaesthesia. Methods: This Prospective Randomized Double-Blind Comparative study was conducted at the Department of Anesthesiology and ICU, Dhaka Medical College Hospital, Dhaka, Bangladesh. The study duration was ten months, from March 2015 to January 2016. A total of 120 participants were randomly included in this study.Each participant was included either into “Group A (n=60)” or “Group B (n=60)” by using fixed number card sampling as mentioned earlier. Group B had been considered as control group in the study, Participants of group A received intravenous ondansetron (0.1 mg/kg body weight) and group B received ephedrine (0.5 mg/kg body weight). Result: The majority of the participants (58.33%) from both groups were from the age group of 26-30 years. Parity distribution revealed that 59.17% (n=71) patients were multigravida while 40.33% (n=49) were primi. In total, 80.33% of the participants had ASA I physical status, and 19.17% had ASA II.
