The Predictors of Prolonged Second Stage of Labor

Abstract

Objective: to study the predictors of prolonged second stage of labor. Material and methods. The study of labors complicated by prolonged second stage has been performed (n = 120). The analysis of the obtained data was carried out in comparison with those of the control group which included primiparas with physiological delivery (n = 30). Results. The labors complicated by prolonged second stage more often started with induction (p = 0.001), more often there was a necessity for oxytocin in delivery (58 % vs 36.6 % in the control group; p = 0.034), the duration of the first stage was longer (435 (295; 520) min vs 305 (255; 470) min; p = 0.035), as well as a higher frequency rate of occiput posterior presentation was noted (14.8% versus 3.3% in the control group; p < 0.001)). Conclusion. The application of labor induction, the necessity for the use of oxytocin, as well as occipital posterior presentation are the predictors for prolonged second period of labor.
