Official title

Phase II, Randomized, Double Blinded, Placebo Controlled Superiority Trial of Prophylactic Intravenous Calcium Gluconate to Decrease Blood Loss at Time of Cesarean Delivery in Pregnant Patients at High Risk for Uterine Atony

Overview

This research study is being done to learn what effect a single dose of calcium gluconate will have on blood loss at the time of cesarean delivery in pregnancy patients at high risk for uterine atony.

Detailed description

This study is FDA IND exempt

Interventions

  • Drug Calcium Gluconate
    slow push intravenous administration of 2g calcium gluconate- 20 mL of 10% Calcium Gluconate in 55mL of IV fluid diluent, Normal Saline CaGluc concentration 26.7 mg/mL
  • Other Saline
    slow push intravenous administration of 75 mL of IV

Primary outcome measures

  • Quantitative Blood Loss (QBL) (continuous variable) administered at Delivery [Time frame: Immediately following surgery]
Secondary outcome measures (8)
  • Quantitative Blood Loss (QBL) (continuous variable) Total [Time frame: 4 hours following surgery]
  • Postpartum hemorrhage [Time frame: 4 hours following surgery]
  • Number of patients with a transfusion requirement [Time frame: Calculated at 48 hours from delivery]
  • Change in Hematocrit (HCT) [Time frame: Preoperative day one, Postoperative day one]
  • Change in Hemoglobin (HGB) [Time frame: Preoperative day one, Postoperative day one]
  • Number of participants with second line uterotonic requirements [Time frame: Calculated at four hours from surgical end]
  • Intensive Care Unit Admission [Time frame: Within 48 hours of cesarean section]
  • Additional hemostasis procedures [Time frame: Within 48 hours of cesarean section]
