Serial intrapartum ultrasound to predict vaginal delivery using angle of progression and head- progression distance in term nulliparous women

ITU offers valuable insights into labour progression. AOP and PD, particularly at cervical dilation of ≥ 6 cm, are predictive of vaginal delivery. Delta AOP serves as the most accurate predictor. Incorporating ITU into routine labour management enhances clinical decision-making, helping reduce unnecessary interventions and caesarean deliveries.
