Decision-Making in Labor Admission Using Transperineal Ultrasound vs. Vaginal Examination

This clinical trial aims to determine whether transperineal ultrasound (a perineal external scan) can improve decision-making for hospital admission in term pregnant women in labor compared to traditional vaginal examination. Term pregnant women (\>37 weeks) presenting with contractions at the emergency department will be randomly assigned to undergo either a transperineal ultrasound or a vaginal examination upon arrival. The study will evaluate whether ultrasound-based assessment reduces the rate of labor inductions and decreases patient discomfort during the admission evaluation. All participants will receive standard clinical evaluation and follow-up according to the assigned method, report discomfort levels using a standardized scale, and have labor outcomes recorded - including induction, oxytocin use, time to delivery, and mode of delivery -, to determine whether ultrasound improves clinical decision-making and maternal comfort.
