The status of the intrauterine fetus in 80 pregnant women with a full-term pregnancy and premature miscarriage was studied, as well as the respiratory adaptation of the babies born. The duration of water-free period in Group 1 (25) women in labor was 6-12 h, in Group 2 (35), 12-20 h, and in Group 3 (20), more than 20 h. Complications occurred in 23 women in labor (weak labor activity, fetal hypoxia), which required the use of abdominal forceps in 4 of them and cesarean section in 3. Labor induction was used in 43 women.
