Effect of Oral Carbohydrate Intake > 44kCal Per Hour During Labour on the Rate of Instrumental Vaginal Delivery
University Hospital, Caen
600 participants
Feb 11, 2022
INTERVENTIONAL
Conditions
Summary
Carbohydrate intake during physical exercise improves muscle performance and decreases fatigue. We hypothesized that carbohydrate intake during labor which is a period of significant physical activity can decrease the instrumental vaginal delivery rate. In a previous study we reported a trend toward a decrease in instrumental vaginal delivery and the mount of carbohydrate intake during labour. However due to some limitations no clear conclusion could be drawn. The present study is designed to examine the relationship between a high calory oral intake (\>44 kCal/hour during labour) and the rate of instrumental delivery.

Interventions
During labor the women will have free access to water and 20 ml commercial fruit juice bricks containing between 430 or 660 kcal/l. Every 2 hours the midwife or the nurse will measure the fruit juice oral intake volume and will advise women to drink the planned volume (1 brick/2hours)
