Clinical Trial Summary

The purpose of this study is to examine whether transperineal ultrasound as visual biofeedback can be used during labor as an effective tool for shortening the second stage of labor and reducing the need for instrumental delivery, in a prospective randomized design.


Description:

Biofeedback provides patients with better control of their body and their physiological reactions respective of the examined process, such as stress/anxiety, sports activity, labor, etc. Women under epidural anesthesia, may frequently feel lack of control over the birthing process and difficulty in bearing down effectively, which is a very significant part of the second stage of labor. Transperineal ultrasound during labor is a standard procedure in many medical centers in the world, mainly used to assist obstetricians in evaluating the progress of labor, fetal head position and assessing the chances of successful operative delivery. One of the most common tools used in transperineal ultrasound in measurement of the angle of progression, which has been suggested as a subjective method for assessing fetal station and for predicting successful vaginal delivery. A preliminary non-randomized study raised the possibility that the use of transperineal ultrasound during labor as a biofeedback tool may shorten the second stage of labor. The purpose of this study is to examine whether this tool can be used during labor as an effective tool for shortening the second stage of labor and reducing the need for instrumental delivery, in a prospective randomized design.
