Study Summary
This study investigates the time course of change in calcium in the blood after a pregnant subject takes an oral dose of calcium carbonate (commonly marketed as "Tums"). This information is important for trials investigating whether calcium can reduce postpartum hemorrhage, bleeding after delivery.
Primary Outcome
Ionized calcium (mmol/L) is measured at baseline and over 5 additional convenience timepoints over the 4 hours after ingestion of calcium carbonate 3000mg.
Interventions
- DRUG Oral calcium carbonate
