Is this trial a fit for you?

Likely a good fit

Ideal candidates are first-time (nulliparous) women at or beyond 37 weeks with a singleton, uncomplicated pregnancy who plan a vaginal birth and have no medical contraindications to oral intake.

Probably not a fit

Women with scheduled cesarean or induction, preterm labor, BMI over 40, diabetes, heart disease, hypertension, or contraindications to pushing or oral intake are unlikely to be eligible or receive benefit.

What this trial studies

This interventional trial compares high-calorie oral carbohydrate intake (>44 kcal/hour) during labor with a control of free water only in nulliparous women with uncomplicated, term singleton pregnancies. Participants are enrolled at Caen University Hospital and receive either carbohydrate drinks during labor or only free water, with labor outcomes recorded. The main outcome is the rate of instrumental vaginal delivery (forceps or vacuum); common exclusions include scheduled cesarean or induction, diabetes, BMI >40, and cervical dilation >8 cm at enrollment. Previous small studies suggested a trend toward fewer instrumental deliveries with increased carbohydrate intake, but this trial aims to provide clearer evidence.

Why it matters

Potential benefit: If successful, this could reduce the need for forceps or vacuum deliveries and lower associated maternal and newborn complications.

How similar studies have gone: Small prior studies, including one by the same group, showed a non-significant trend toward fewer instrumental deliveries with higher carbohydrate intake, so the approach is plausible but not yet proven.
