PHENYLEPHRINE is commonly used to maintain blood pressure during spinal anesthesia for cesarean delivery.1,2 However, because phenylephrine is a potent α-adrenergic receptor agonist without β-adrenergic receptor activity at usual clinical doses, its use is often associated with a dose-related reflexive slowing of maternal heart rate (HR) and a corresponding decrease in cardiac output (CO).3–5 Although the clinical significance of these decreases in HR and CO in healthy patients with unstressed fetuses is unknown, concern has been expressed that there may be potential for harm in the presence of a compromised fetus.3 Therefore, investigation of alternative vasopressors with less pronounced reflexive negative chronotropic effects is of interest.
