Overview

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.

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?
