Brief Summary

Maternal hypothermia is very frequent after caesarean delivery under spinal anaesthesia and should be prevented, as it induces discomfort and increases the risk of postoperative complications. Several modalities of active warming have been explored, with contrasting results. Small IV Fluid warming systems offer effective and safe IV fluid warming without discomfort, and are very easy to use. The investigators hypothesize that such devices can efficiently prevent hypothermia after caesarean section even with high flow rates of infusion. The purpose of this study is to determine whether active fluid warming reduces the occurrence of maternal hypothermia after scheduled caesarean section, as compared with no active warming. The investigators plane to conduce a double-blinded randomized controlled trial. Seventy women undergoing scheduled caesarean section under spinal anaesthesia in 3 different maternity units will be included. The primary outcome is the occurrence of maternal hypothermia (\<36.0°C) on admission to the post anaesthesia care unit. The secondary outcomes are perioperative maternal hypothermia, maternal thermal discomfort, maternal recovery and neonatal well-being

Study Arms (2)

The control group

NO INTERVENTION

Control group according to usual practices: no active warming (no fluid warming). The fluid warmer device will be set up but not activated. The control group will receive IV fluid coload at room temperature through the fluid warmer set to "off". The device is hidden

The warming group

EXPERIMENTAL

"IV fluid warming with the enFlow® or Fluido®Compact IV fluid warmer" : Women will receive IV fluid coload warmed to 40°C through the enFlow® or Fluido®Compact device. The box will be also hidden. The fluid warmer will be turned off at the end of surgery, just before transfer to the PACU.

Device: enFlow® IV fluid warmer and from July 2019 Fluido®Compact IV fluid warmer

Interventions

The fluid warmer will be set up by an external co-investigator in every patient included in the study. It will be turned on in patients belonging to the "warming" group, and turned off in the control group
