This randomized controlled trial aims to compare the effectiveness of different doses of ephedrine infusion in preventing maternal hypotension following spinal anesthesia in parturients undergoing cesarean sections. The study includes 120 participants, aged 18-40 years, with American Society of Anesthesiologists (ASA) physical status II, who are scheduled for elective cesarean delivery. The primary objective is to determine whether low-dose ephedrine infusions at 1.25 mg/min or 1.5 mg/min effectively reduce the incidence of maternal hypotension, with secondary outcomes assessing the need for rescue ephedrine, incidence of side effects (nausea, vomiting, tachycardia), and neonatal Apgar scores. Researchers will compare three groups-saline, 1.25 mg/min ephedrine, and 1.5 mg/min ephedrine-to evaluate their impact on maternal hemodynamic stability.

Incidence of Hypotension in Patients Undergoing Cesarean Section Following Spinal Anesthesia.
Timeframe: Hypotension episodes were monitored and recorded intraoperatively, immediately following the administration of spinal anesthesia until the end of the cesarean section procedure. The time frame for evaluating this outcome was during the surgical procedure
