Carbetocin Compared To Oxytocin During Cesarean Delivery

Undesired Effects of Carbetocin Compared To Oxytocin Administered As Single Intravenous Dose or Infusion During Cesarean Delivery: A Prospective Randomised Controlled Study

As both oxytocin and carbetocin are used daily in obstetric units all over the world, the investigators find it compelling to investigate whether the hemodynamic and myocardial effects of oxytocin and carbetocin are comparable in healthy women during delivery and determine any potential harmful effects following the use of oxytocin or Carbetocin as uterotonic. Other endpoints relating to uterus tone, blood loss, blood pressure, heart rate, post-operative pain and side effects will also be assessed.

Although the difference between carbetocin and oxytocin in terms of hemodynamic changes, postpartum blood loss and incidence of side effects is not statistically significant. serious cardiovascular adverse events, including ST segment depression, hypotension and tachycardia have been reported after IV oxytocin. Oxytocin dose reduction and/or increased infusion duration may reduce risk of some cardiac-related adverse effects and increase patient safety.
