Compare two norepinephrine doses to prevent low blood pressure after spinal anesthesia for C-section

The Effect of Two Different Doses of Noradrenaline on Hypotension Caused by Spinal Anesthesia for Cesarean Section

NA · Assiut University · NCT06102382

What this trial studies

This single-center interventional study compares two prophylactic norepinephrine infusion rates given around the time of spinal anesthesia for planned cesarean delivery. Eligible term pregnant women without major cardiac disease, hypertensive disorders, severe obesity, or contraindications to spinal anesthesia will receive one of the two norepinephrine regimens during the operation. Maternal blood pressure, need for rescue vasopressors, and common side effects such as nausea, bradycardia, or hypertension will be recorded and compared between groups. The goal is to identify which infusion rate better prevents post-spinal hypotension with acceptable safety.

Who should consider this trial

Good fit: Pregnant women at term (≥37 weeks) scheduled for elective cesarean under spinal anesthesia who do not have cardiac disease, hypertensive disorders of pregnancy, severe obesity, or contraindications to spinal anesthesia.

Not a fit: Women with cardiac morbidities, hypertensive pregnancy disorders, severe obesity (BMI ≥40), significant prepartum hemorrhage, or those who decline spinal anesthesia would not be candidates and are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, the preferred norepinephrine dose could reduce episodes of maternal low blood pressure during cesarean delivery and decrease the need for rescue medications and associated symptoms.

How similar studies have performed: Previous small studies and clinical reports have shown promising results with norepinephrine for preventing post-spinal hypotension, but the optimal prophylactic dose has not been established.
