Summary

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.

Conditions

• Hypotension After Spinal Anesthesia
• Hypotension During Cesarean Delivery

Interventions

Type	Name	Description
DRUG	Normal Saline (Placebo)	Participants in the control group receive a continuous intravenous infusion of normal saline, which serves as an inert placebo with no pharmacological effect. This intervention mimics the administration of the active treatments, allowing for direct comparison with the ephedrine groups to assess the effectiveness of the drug in preventing maternal hypotension during spinal anesthesia.
DRUG	Ephedrine	The interventions in this study include a control group receiving normal saline, which serves as an inert placebo to assess the effectiveness of the active treatments. Participants in Group B receive an ephedrine infusion at 1.25 mg/min, while those in Group C receive a higher dosage of 1.5 mg/min. This design allows for direct comparison of the two dosages of ephedrine against the control, enabling evaluation of their effectiveness in preventing maternal hypotension following spinal anesthesia during cesarean sections.
