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.
Pregnant female subjects at the study institution, admitted for labor (spontaneous, augmented, or induced)
severe range blood pressure (BP >160/>110) within the 48 hours prior to delivery
patient age <18 years or >45 years
renal dysfunction with a documented serum Cr > 1.0 mg/dL
known history of congenital or acquired cardiac disease or history of arrhythmia
