Abstract

Objective: The objective of the study was to assess whether the measurement of the angle of progression in nulliparous women in labour can predict the mode of delivery.

Methods: This prospective observational study was conducted at Benazir Bhutto Hospital, Rawalpindi Medical University from 16^th February to 25^th March 2024. Nulliparous pregnant women in the active first stage of labour with singleton pregnancy and cephalic presentation were included in the study after taking informed consent. The angle of progression (AOP) was measured by trans-perineal ultrasound using the curvilinear probe. The primary outcome was the mode of delivery in relation to angle of progression.

Results: Seventy-eight patients were included in the study. Angle of progression was wider in patients who underwent vaginal delivery and narrower in patients who underwent cesarean section. AOP of 121 or more is associated with 86.6% of vaginal delivery and an angle of progression of 70 or less is associated with 83.3% of cesarean section.

Conclusion: The angle of progression is a reliable tool for predicting the mode of delivery. Wider angle is associated with vaginal delivery and a narrower angle is associated with cesarean section.

期刊介绍： It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad. Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
