Eligibility Criteria

Age19 Years+
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Pregnant patients ≥ 36 weeks gestation, for elective Cesarean delivery under neuraxial anesthesia
  • American Society of Anesthesiologists (ASA) class 2
  • Patients ≥ 19 years of age

You may not qualify if:

  • Long QT syndrome
  • Cardiac disease or rhythm abnormalities
  • Family history of long QT syndrome or abnormal cardiac conduction
  • Currently taking medication that is known to prolong the QT interval
  • Women who are high risk for uterine atony as outlined in SOGC
  • Known allergic reaction or hypersensitivity to Carbetocin or any other oxytocin homologue
  • Patients who are unable to give informed consent because of a language barrier as the study team only speaks English and will be unable to complete consent process and study procedure appropriately.

Limitations and Caveats

No data exists that stratifies risk by measuring absolute Tp-e change We excluded patients with low repolarization reserves, or a resistance to oxytocin. We also excluded emergent C-sections, combined spinal/epidurals, and General Anesthesia
