NCT03973411

Brief Summary

Ondansetron, a potent 5-HT 3 receptor antagonist commonly used as an antiemetic. The main objective of the present study is to verify the hypothesis that blocking type 3 serotonin receptors with intravenous ondansetron reduces the incidence of spinal anesthesia-induced hypotension
