Abstract: Background:Spinal anesthesia is a simple, reliable, and most common anesthetic technique practiced worldwide. Hemodynamic instability is most common intraoperative complication after spinal anesthesia during cesarean delivery. Spinal anesthesia causes bradycardia and hypotension via activation of Bezold-Jarisch reflex. Ondansetron is specific 5- HT3 receptor antagonist that alleviates the Bezold-Jarisch reflex lead to decrease hypotension and bradycardia.Despite the popularity and ease of its use, this procedure is frequently associated with hemodynamic instability......
