What this Trial Is About
Researchers are studying whether taking in carbohydrates during labor, which is a physically demanding time, can reduce the chance of needing an instrumental vaginal delivery. This study focuses on women having their first baby with a single, uncomplicated pregnancy and no conditions that prevent vaginal delivery. The aim is to see if consuming more than 44 kilocalories per hour during labor affects delivery outcomes. Participants are randomly assigned to one of two groups. One group will only have free access to water during labor, while the other group will have free access to water and additional carbohydrate intake from commercial fruit juice bricks, each containing between 430 and 660 kcal per liter. The juice intake is measured every two hours, and women are encouraged to drink one brick every two hours. This approach helps evaluate the impact of higher calorie oral intake on labor outcomes. During the study, researchers will monitor the rate of instrumental vaginal deliveries as the primary outcome within two days of labor. They will also observe other factors such as the use of oxytocin, cesarean section rates, nausea, vomiting, thirst, hunger, fatigue, and umbilical blood pH shortly after birth. The study includes women aged 18 to 60 and tracks these measures to assess how carbohydrate intake during labor may influence delivery and maternal well-being.
