First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 1 time

Summary

This study tests whether giving a single dose of calcium gluconate before a cesarean delivery can reduce blood loss in women at high risk for heavy bleeding. Researchers will compare calcium gluconate to a placebo in 140 pregnant volunteers. The goal is to see if this simple, inexpensive drug can prevent dangerous bleeding and the need for transfusions.
