Comparing Norepinephrine and Ephedrine for Managing Low Blood Pressure During Cesarean Sections

Management of Postspinal Anesthesia Hypotension During Elective Cesarean Section: Baby Norepinephrine Versus Ephedrine

Not applicable Interventional Hopital Charles Nicolle · NCT06498076

What this trial studies

This study evaluates the effectiveness and safety of diluted norepinephrine compared to ephedrine in managing hypotension that can occur after spinal anesthesia during elective cesarean sections. Spinal anesthesia is preferred for its safety benefits, but hypotension is a common complication that can affect both mother and baby. The study will be conducted as a prospective randomized double-blind trial at Charles Nicolle Hospital, involving consenting full-term pregnant women scheduled for cesarean delivery. The aim is to determine which vasopressor better maintains maternal blood pressure while minimizing adverse effects.

Who should consider this trial

Good fit: Ideal candidates are singleton full-term pregnant women aged 18-38 years, classified as ASA grade II, scheduled for elective cesarean sections under spinal anesthesia.

Not a fit: Patients with ASA grade III or IV, contraindications to spinal anesthesia, or significant comorbidities such as preeclampsia or cardiovascular disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve maternal and neonatal outcomes by providing a safer method for managing hypotension during cesarean sections.

How similar studies have performed: Previous studies have explored the use of various vasopressors for managing hypotension during anesthesia, but the specific comparison of diluted norepinephrine and ephedrine in this context is relatively novel.
