Trial of Ultrasound-guided Rotation for Normalizing Head Position

Intrapartum Ultrasound-Guided Early Manual Rotation for Correcting Abnormal Fetal Head Position The goal of this clinical trial is to learn whether using ultrasound during labor, followed by early manual rotation of the baby's head when needed, can help more women give birth vaginally when the baby's head is facing an unfavorable direction. During labor, most babies turn so the back of the head faces the front of the mother's pelvis. This position usually makes birth easier. Some babies remain in a back-facing or side-facing position, called occiput posterior or occiput transverse position. These positions may make labor longer and may raise the chance of assisted vaginal birth or cesarean birth. In this study, trained midwives or obstetric clinicians will use intrapartum ultrasound, which is an ultrasound scan during labor, to check the baby's head position. Ultrasound is non-invasive and can give a clearer and more objective picture than examination by touch alone. If the baby's head is in an unfavorable position and the participant meets the study safety criteria, the clinician may try manual rotation. Manual rotation means using the hand to gently help turn the baby's head into a more favorable front-facing position. Researchers will compare two groups. One group will receive ultrasound-guided early manual rotation when the cervix is about 5 to 7 centimeters open and the baby's head is low enough. The other group will receive usual labor care, including standard examinations and usual clinical management. Participants will be assigned to one of these groups by chance, like flipping a coin. The main question is: Does ultrasound-guided early manual rotation increase the chance of vaginal birth? The study will also learn about safety and other birth outcomes, including whether the baby's head turns successfully, how long labor lasts, whether forceps or cesarean birth is needed, bleeding after birth, fever or possible infection, perineal injury, the mother's bir
