Obstetric AnesthesiaPrevention of Spinal Anesthesia-Induced Hypotension During Cesarean Delivery by 5-Hydroxytryptamine-3 Receptor Antagonists A Systematic Review and Meta-analysis and Meta-regressionHeesen, M.; Klimek, M.; Hoeks, S.

As 5-hydroxytryptamine (5-HT3, serotonin) receptors are involved in this mechanism, studies have evaluated 5-HT3 receptor antagonists for their potential to prevent spinal anesthesia–induced hypotension.
