Brief Summary

Preeclampsia (PE) is an obstetric placental vascular pathology with a prevalence of 2 to 5% of pregnant women. It is defined by learned societies by the association of high blood pressure (BP≥140/90mmHg) and proteinuria \> 0.3g/day. The last French Maternal Mortality Report 2024 places cardiovascular complications among the main causes of maternal death. PE has an increasing number of deaths in 2016-2018 and significant preventability (66%).

Cesarean sections in pre-eclamptic patients are difficult procedures and, do not benefit from any specific recommendations. Cesarean section is promptly performed under regional anesthesia by spinal anesthesia or spinal anesthesia with combined epidural, techniques that cause maternal arterial hypotension with consequences for the baby.

These hypertensive patients, often on antihypertensives, challenge the anesthesiologist to manage the hemodynamic balance between the risk of arterial hypotension generated by the anesthesia corrected by vasoactive amines and the risk of major hypertension secondary to their management. The major risk in these patients with low platelet counts is hemorrhagic stroke.

Our study is an observational, bi-centric study between the maternity wards of the Clermont Ferrand and Lille University Hospitals.

It consists of collecting data prospectively on all pre-eclamptic patients undergoing a non-urgent cesarean section.

The objective is to observe the management of hemodynamics and calculate the prevalence of complications such as maternal hypotension and/or hypertension through the implementation of non-invasive monitoring (ClearSight).

Patients meeting the inclusion and non-inclusion criteria may be included in the study by an investigator after having given a non-opposition agreement after having received clear and fair information about the study.

In any case, the care of patients participating in the study will not be modified in any way compared to the usual practices of the services.

Primary Outcome Measures
NameTimeMethod
Hemodynamic events.During the entire cesarean procedure including anesthesia.

Prevalence of the occurrence of events such as maternal arterial hypotension and/or arterial hypertension during a cesarean section in a known pre-eclamptic patient.

Secondary Outcome Measures
NameTimeMethod
Duration of maternal hypotensive or hypertensive episodes.During the entire cesarean procedure including anesthesia.

Defined by the time-weighted average intraoperative PAS below a threshold of 110mmHg or above a threshold of 170mmHg. This measurement is commonly called TWA (Time Weighted Average), corresponding to the area between the chosen PAS threshold and the measured PAS curve, divided by the total measurement time.

Number of maternal hypotensive and/or hypertensive episodes.During the entire cesarean procedure including anesthesia.
Occurrence of major adverse events.During the entire cesarean procedure including anesthesia.
Nature and dose of local anesthetic administeredDuring the entire cesarean procedure including anesthesia.
Nature and management of antihypertensive drugs during cesarean section.During the entire cesarean procedure including anesthesia.
