Eligibility Criteria

Inclusion

  • Scheduled CD for patients ≥ 37 weeks excluding high risk factors for uterine atony
  • Neuraxial anesthesia as the primary anesthetic where intrathecal medications are the primary anesthetic

Exclusion

  • Risk factors for uterine atony including:
  • Overdistended uterus due to fetal macrosomia reported on prenatal ultrasound \>90th centile or \> 4000 gm, multiple gestation, grand multiparity (≥5 births at ≥ 20 weeks gestation), polyhydramnios
  • History of uterine atony/PPH (documented with blood loss \> 2000 ml, blood transfusion, use of surgical methods such as Bakri balloon, B-Lynch sutures, uterine artery ligation or embolization)
  • Obesity with body mass index (BMI) \> 40 kg/m2
  • Placenta previa and/or placenta accreta
  • Digoxin therapy within 14 days (hypercalcemia can exacerbate digoxin toxicity)
  • Patients needing intraoperative IV ceftriaxone or tetracycline.
  • Kidney disease including Stage 3 chronic kidney disease, serum creatinine above 120 mmol/L or GFR \<60 ml/min (to prevent hypercalcemia due to reduced creatinine clearance in those with impaired kidney function as calcium is renally excreted)
  • Calcium channel blockade within 24 hours (opposing effect)
  • Known history of cardiac disease including arrhythmias, ischemia, and congenital heart disease (to avoid attributing cardiac symptoms to study drugs)
  • Preexisting hypertension, preeclampsia or persistent elevated blood pressure above 160/100 mmHg requiring treatment
  • Emergency cesarean deliveries or women in labor
  • Planned general anesthetic for patients where neuraxial is contraindicated.
