Objective. To compare the efficiency of labor induction in full term (284-285 days) and late term (> 287 days) pregnancies. Subjects and methods. The investigation enrolled 129 patients (78patients with full term pregnancy and 51 with late term pregnancy) having indications for labor induction. A double-balloon catheter for preparing the cervix was inserted for 12 hours. After catheter removal, according to the ripening of the cervix uteri, the latter was additionally prepared using dinoprostone gel or amniotomy (oxytocin-induced labor induction in the absence of an effect). Results. Labor was started with the inserted balloon in 35.9% of full term pregnancies versus 23.53% of late term ones (p = 0.003). The balloon insertion to delivery interval was shorter in the full term pregnancy group (p = 0.04). The vaginal delivery rate within 24 hours after balloon insertion was higher in the full term pregnancy group (75.64% versus 49.02% (p = 0.002)). The rate of failed induction of labor, uterine inertia, and cesarean section was higher in the late term pregnancy group (1.28% versus 13.73%) (p = 0.02) (3.85% versus 17.65%) (p = 0.01), 16.67% versus 31.37% (p = 0.04), respectively. All babies were born alive. The newborns from mothers in the late term pregnancy group more frequently showed signs of over-maturity (2.56% versus 13.73% (p = 0.02). Conclusion. Labor induction proved to be more effective in the full term pregnancy group than in the late term pregnancy group.
