Study of the impact of preoperative oral rehydration on the incidence of spinal anesthesia-induced hypotension for scheduled cesarean section.

What is already known ? Arterial hypotension is one of the most common complications following spinal anesthesia (60%). Several measures have been studied to prevent this hypotension, such as intravenous vascular filling (preloading, coloading), using different filling fluids (colloids vs crystalloids), preventive administration of vasopressors, reduction of doses and volumes administered in spinal anesthesia.

Only one study has evaluated the impact of oral rehydration on hypotension after spinal anesthesia.

Hypothesis:

The investigatord wish to demonstrate that an oral rehydration 2 hours before surgery, reduces by 50% the incidence of hypotension and / or the use of vasopressors, after spinal anesthesia

Primary outcome:

Decrease in the incidence of hypotension and / or use of vasopressor agents by 50% in the "rehydration" group compared to the "fasting" group.

Secondary outcomes:

Reduced incidence of nausea / vomiting side effects, effect on umbilical pH, APGAR score, patient satisfaction

Design:

Interventional clinical study. Monocentric, single-blind, randomized, single-blind, controlled trial with 2 groups of 50 patients.

Inclusion criteria:
