Prospective, Observational and Bicentric Study of the Management of Arterial Hypotension During Planned Caesarean Section. Practice Comparison Between a Referral Center Using According to Service Protocol, an Intravenous Ephedrine/Phenylephrine Mixture at the PSE Versus Another Referral Center Using According to Service Protocol Intravenous Baby Noradrenaline

Comparison of two practices of obstetrical services between the CHU of Clermont Ferrand and the HFME Lyon-Bron in the management of arterial hypotension during an elective cesarean section

The investigators propose to carry out a bicentric strict observational prospective study between the maternity of the HFME of Lyon-Bron which uses the mixture ephedrine / noradrenaline with the PSE for many years in service protocol for the management of hypotension for cesarean section under perimedullary anesthesia and the CHU of Clermont-Ferrand which uses baby noradrenaline 10 mcg/mL PSE for this same indication according to an institutional protocol. Patients corresponding to the inclusion and non-inclusion criteria will be recruited by a physician investigator and will give their agreement of non-opposition after having received clear oral and written information about our study. The care will not be modified in any way compared to the usual practices of the service.
