Increase of caesarean section (CS) is a global issue. In 2001, WHO proposes the Robson classification system as a standard for monitoring and comparing caesarean section rates. In Viet Nam, the most common and changeable indication for caesarean section is failed labor augmentation. Objectives: To determine caesarean section rate and its associated factors in pregnant women who had labor augmented by using oxytocin at Tu Du hospital. Method: Case series. The study reported on a series of 334 pregnant women who had a singleton gestation, vertex, 34-42 weeks of gestation, had labor augmented by using oxytocin at Delivery department of Tu Du hospita f-rom 1st Jan to 30th May, 2020. Results: A total of 334 pregnant women were recruited. The CS rate was 45.2%. The associated factors were maternal age, previous CS, duration of staying in the labor ward, maternal height /uterus height ratio, had delivered 1 or more than 1 term pregnancy, cervical dilatation at oxytocin start, and BISHOP at oxytocin start. Conclusion: In pregnant women who had labor augmented by using oxytocin, caesarean section rate is high.
