Background: One of the most vital components of the management of females through labor is evaluating their delivery progress. It is imperative to consider the extent of delivery progress when determining whether or not to intervene in a natural delivery. Aim: This investigation aimed to estimate the role of measuring intrapartum angle of progression (AOP) in prediction of mode of delivery in primigravidae women to improve fundings offetus and mother.
Patients and methods: This investigation has been carried out as a descriptive cross-sectional investigation conducted in the Emergency Unit of Obstetrics and Gynecology Department, Suez Canal University, involving 127 participants of full-term primiparous women.
Results: The females who delivered vaginally had a significantly higher mean of AOP of 114.3 ± 7.13 compared to those with cesarean section (CS(, whose AOP was 94.48 ± 5.59, with a p-value lower than 0.001. Also, there was statistically significant variance among both groups in head station, as vaginal delivery (VD) had a lower head station than CS. AOP ≥98.5 had the highest diagnostic accuracy in predicting vaginal delivery, followed by cervical dilatation rate ≥2.75 and then head station ≥0.
Conclusion: In conclusion, our study found that the AOP positively correlates with VD; AOP ≥98.5 had the highest diagnostic accuracy in predicting vaginal delivery.
