Not applicable Interventional General Hospital of Ningxia Medical University · NCT06151431

What this trial studies

This study investigates the effects of different maternal blood pressure maintenance targets on neonatal outcomes in preeclamptic patients undergoing cesarean sections. It addresses the common complication of post-spinal anesthesia hypotension, which can occur in a significant percentage of cases without proper management. The research will compare the standard practice of maintaining blood pressure above 80% of baseline with a more intensive target of above 90% of baseline, utilizing alpha-adrenergic receptor agonists as a treatment strategy. The goal is to determine if stricter blood pressure control can lead to better outcomes for newborns.

Who should consider this trial

Good fit: Ideal candidates are preeclamptic women aged 18-45, scheduled for cesarean section under spinal anesthesia, with singleton pregnancies of at least 32 weeks.

Not a fit: Patients with chronic hypertension, eclampsia, or significant fetal distress may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved neonatal outcomes for preeclamptic patients undergoing cesarean sections.

How similar studies have performed: While the approach of maintaining blood pressure above 90% of baseline is suggested, limited evidence exists to support its advantages over the standard practice, making this study a novel investigation.
