Calcium Chloride for Prevention of Uterine Atony During Cesarean

In this pilot study, investigators will administer calcium chloride or placebo to pregnant women undergoing Cesarean delivery who have been identified as high risk for hemorrhage due to poor uterine muscle contraction, or atony. They will assess whether a single dose of calcium given immediately after the delivery of the fetus decreases the incidence of uterine atony and bleeding for the mother. The pharmacokinetics of calcium chloride in pregnant women will also be established. Data from this pilot study of 40 patients will be used to determine sample size and appropriateness of a larger randomized clinical trial.

   - a degree of case urgency to which taking time to consent for the study could
   compromise patient care, determined by anesthesiologist or obstetrician

   - patient age <18 years or >50 years

   - renal dysfunction with serum Creatinine > 1.0

   - abnormal cardiac function or history of arrhythmia
