Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Currently oxytocin is used as a common uterotonic agent in obstetrics. The use of this drug in uterotonic reasons can cause serious haemodynamic side effects which has been shown by several investigators.
Preliminary clinical observations of maternal heart rate and blood pressure suggest that that the use of carbetocin causes less hemodynamic changes than oxytocin.
Primary objective(s):
To evaluate the effect of carbetocin on maternal hemodynamic parameters (heart rate, blood pressure, systemic vascular resistance, cardiac output, stroke volume, heart rate variability, and blood pressure variability) in a non-invasive setup (TaskeForce®-Monitor) during primary Caesarean section.
To compare the haemodynamic changes of carbetocin versus oxytocin.
Secondary objective(s) To evaluate the need of additional drugs and methods to control uterine tone.
