Hypotension Prediction Index vs Norepinephrine Infusion for Prevention of Spinal Hypotension for Cesarean Delivery

The goal of this randomized controlled trial is to compare for non inferiority for fetal wellbeing Hypotension Prediction Index - Guided Therapy and Continuous Norepinephrine Infusion in in the Prevention of Spinal Anesthesia-Induced Hypotension for Cesarean Delivery. The main question it aims to answer are: • are fetal arterial base excess comparable with the two treatments? Participants will undergo continuous noninvasive hemodynamic monitoring with advanced Hypotension Prediction Index Researchers will compare with patients receiving continuous norepinephrine infusion and standard blood pressure monitoring with arm cuff.
