Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Maternal posturing is used during labor to facilitate the rotation of occipitoposterior fetal position in anterior.

Our study aims to evaluate the efficacy of asymmetrical lateral decubitus for rotation of the fetal head.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The prevalence of fetal occipitoposterior position during labor is 20%. Compared to anterior positions, they are known to be at higher risk of complications (cesarean section, instrumental delivery, severe perineal laceration).

Maternal posturing is used during labor to facilitate the rotation of the fetal head in anterior position. Asymmetrical lateral decubitus is used frequently, without having ever been evaluated.

Our study aims to evaluate the efficacy of this maternal posturing, through a randomized open trial.

We hypothesized that posturing women in asymmetrical lateral decubitus allows increasing frequency of anterior fetal position after 1 hour.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Asymmetrical Lateral Decubitus

Women in labor are postured in pronounced lateral decubitus (side opposite to the back of the fetus), with the inferior leg in extension, and the superior leg in hyperflexion

Group Type EXPERIMENTAL

Asymmetrical Lateral Decubitus

Intervention Type OTHER

After randomization, women are postured in pronounced lateral decubitus (side opposite to the back of the fetus), with the inferior leg in extension, and the superior leg in hyperflexion, during 1 hour (minimum 30 minutes).

Then, women are encouraged to take this posture during labor as frequently as possible if the fetus remains in occipitoposterior position
