Background: Spinal Anesthesia is a common type of anesthesia used during many surgical procedures. This regional technique can be accomplished by administering an intrathecal dose of hyperbaric local anesthetic solution. The local anesthetic within the subarachnoid space can block sensory, motor and sympathetic pathways. Objectives: The Purpose of this study was to find out the effectiveness of prophylactic administration of intravenous ondansetron for attenuation of spinal anesthesia induced hypotension in non-obstetric spinal anesthesia surgeries. Patients and Methods: Therefore, A prospective double-blind, placebo-controlled, randomized study was found to be the most suitable design in order to achieve the study objectives. A total of 90 patients males & females included in the study, aged 20-40 years, and were divided equally into two groups: Group A received 8mg ondansetron diluted in volume of 10cm normal saline 5 minutes prior to spinal anesthesia. Group B received a placebo of 10cm normal saline 5 minutes prior to spinal anesthesia. Results: There was no statistically significant difference found between the two studied groups regarding demographic data, anthropometric measures, ASA score and total time of surgery. There was statistically significant increase in the incidence of hypotension immediately after spinal and at 5 min in placebo group than ondansetron group with p-value = 0.026 and 0.014 respectively. Conclusion: The present study demonstrated that, among patients who received spinal anesthesia with bupivacaine for elective for surgeries below umbilicus, prophylactic intravenous ondansetron 8mg iv 5 mins prior to spinal anesthesia reduced spinal anesthesia induced hypotension decreases in SBP, MAP, and heart rate. Ondansetron did not have a significant effect on DBP. Ondansetron did not have a significant effect on DBP. The incidence of nausea and vomiting was lower following the administration of ondansetron, and vasopressor use and dosages were reduced. [ABSTRACT FROM AUTHOR]
