The course of labor in postterm pregnancy in Mongolian women

Objective. To study and compare the characteristics of the course of labor in women who had a postterm pregnancy. Materials and methods. Information for studying the characteristics of the course of labor was obtained from 366 mothers who had a postterm pregnancy and 695 mothers whose pregnancy was normal. All women gave birth in 2017-2018. The data were processed using the IBM SPSS 23 software package. Results. Fetal hypoxia was observed in 67cases in the group of patients with a postterm pregnancy and in 52 women whose pregnancy was normal; oligohydramnios was revealed in 81 cases in the group of patients with a postterm pregnancy (p=0.000). Cephalopelvic disproportion was observed in 59 women with a postterm pregnancy and in 45 women whose pregnancy was normal (p=0.000). The women with postterm pregnancy had fetal distress more often than those with normal pregnancy (p=0.000). Cesarean section was more common in women with postterm pregnancy, namely, 107/366 (29.23%) patients compared to 66/695 (9.49%) women with normal pregnancy, (p=0.000). The mean length of the newborn in the group with a postterm pregnancy was 52.63 (1.89) cm, and it was 50.67 (1.68) cm in women with a normal pregnancy; the mean weight of the newborn in the group with a postterm pregnancy was 4094.39 (302.624) g, and in women with a normal pregnancy it was 3444.73 (267.766) g (p=0.000). The mean height of the mother in the group with a postterm pregnancy was 162.69 (5.917) cm, and in case of a normal pregnancy it was 161.32 (5.776) cm; the mean weight of the mother in the group with a postterm pregnancy was 77.986 (11.282) kg, and in case of a normal pregnancy it was 72.349 (10.263) kg (p=0.000). The analysis of the course of labor revealed a greater number of complications in women with a postterm pregnancy than in women whose pregnancy was normal (p=0.000). Conclusion. The course of labor in women who had a postterm pregnancy is characterized by numerous complications: fetal hypoxia, oligohydramnios, fetal distress, birth trauma, as well as a high frequency of cesarean section.
