Spinal Anaesthesia for Caesarean Section: Descriptive Multicentre Study
Spinal Anaesthesia for Caesarean Section: Descriptive Multicentre Study
Most of caesarean sections can be performed under spinal anaesthesia. Its major advantages
 are reliability and fast onset. However, dose of hyperbaric bupivacaine used, combination
 with adjuvants, hemodynamic management, and impact of these measures on maternal experience
 are not uniform. This study aims to describe practices of spinal anaesthesia for caesarean
 section in France to improve practices, guide new studies and establish protocols.
Most of caesarean sections can be performed under spinal anaesthesia. Its major advantages
 are reliability and fast onset. However, techniques of spinal anaesthesia are varied. Dose of
 hyperbaric bupivacaine used may shifted, varying intensity of sensor block but also
 hemodynamic side effect. Likewise, use of adjuvant is frequent and differs between centres.
 Management of the maternal hemodynamic is also discussed. While it is recognized that
 intraoperatively vascular filling alone is not effective, use of vasopressors is not
 unequivocal. For example, recent studies support the use of norepinephrine.

 Finally, maternal experience is a hot topic. Although insufficient anaesthesia is rare, it is
 often overlooked. There are few recommendations on the intraoperative treatment of
 insufficient anaesthesia and to the management of post-traumatic stress that it lead to.

 The objective of this study is to describe practices of spinal anaesthesia for scheduled or
 non-emergency caesarean section (also named "green code") in France by detailing several
 points:

 Technique of spinal anaesthesia:

 -  The anaesthesia solution used (doses and adjuvants)

 -  Management of hemodynamic

 -  Management of insufficient anaesthesia

 -  Maternal experience It aims to make an inventory of practices, to orient future studies,
 guide practice and the realization of protocols.

 It is an observational study unfolds from 2021 to 2022. It concerns 11 French centres and 600
 women. Data are collected with an online questionnaire.
Inclusion Criteria:
