What this trial studies

This clinical trial investigates the use of Calcium Gluconate to reduce postpartum hemorrhage during elective cesarean deliveries. Participants will receive either Calcium Gluconate or a saline solution in addition to Carbetocin, a uterotonic agent, to assess its effectiveness in minimizing blood loss. The study will monitor calcium levels and coagulation profiles before and after surgery to ensure patient safety and evaluate outcomes. Only women with normal calcium levels and no QT interval abnormalities will be included in the trial.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of postpartum hemorrhage and improve maternal outcomes during cesarean deliveries.

How similar studies have gone: While the use of calcium in managing bleeding is established, this specific application in elective cesarean deliveries is novel and has not been extensively tested.
