What this trial studies

This clinical trial aims to compare the effects of continuous infusion of norepinephrine versus phenylephrine on blood pressure maintenance during spinal anesthesia for elective cesarean sections. It is a randomized, double-blind, two-arm, parallel, non-inferiority trial conducted at Hassan II University Hospital in Fes, Morocco. Participants will receive either norepinephrine or phenylephrine, with infusion rates adjusted based on maternal arterial pressure, to assess differences in neonatal outcomes and maternal hemodynamics.

Who should consider this trial

Good fit: Ideal candidates include full-term, singleton, non-laboring pregnant women scheduled for elective cesarean delivery under spinal anesthesia with stable baseline blood pressure.

Not a fit: Patients with known fetal abnormalities, preexisting hypertension, or contraindications to spinal anesthesia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve blood pressure management during cesarean deliveries, leading to better outcomes for both mothers and their newborns.

How similar studies have performed: Previous studies have shown varying results with similar approaches, but this specific comparison of norepinephrine and phenylephrine in this context is relatively novel.
