Labor Cervical Exams: 2 hrs, 4 hrs, 8 hrs?

From Dr. Chapa’s OBGYN Clinical Pearls Dr. Chapa’s Clinical Pearls

Routine vaginal examinations (VEs) are a standard component of intrapartum care, traditionally performed at regular intervals to monitor cervical dilation, effacement, and fetal station, which are indicators of labor progression. Yet, the American College of Obstetricians and Gynecologists states that there is insufficient evidence to recommend a specific frequency for cervical examinations during labor, and examinations should be performed as clinically indicated. Now, a recently published RCT form AJOG MFM is adding additional credence to that. Can we space out clinical exams in otherwise “low-risk” laboring women to 8 hours? Listen in for details.
