Key result
Pre-eclampsia during caesarean delivery was associated with an inability to increase stroke index at the moment of delivery compared to healthy controls, suggesting left ventricular dysfunction.

How does pre-eclampsia modify maternal haemodynamics during elective caesarean delivery compared to normal pregnancy?
Pre-eclampsia impairs the left ventricle's ability to increase stroke volume in response to the volume load of delivery during caesarean section, potentially increasing the risk of pulmonary edema.
Tihtonen et al. (2006) conducted an observational in Pre-eclampsia (n=20). Pre-eclampsia vs. Healthy uncomplicated pregnancy was evaluated on Stroke index (SI), heart rate (HR), cardiac index (CI), systemic vascular resistance index (SVRI) and mean arterial pressure (MAP). Pre-eclampsia during caesarean delivery was associated with an inability to increase stroke index at the moment of delivery compared to healthy controls, suggesting left ventricular dysfunction.
