Based on retrospective study of 9671 labor histories and prospective investigation of 90 females whose pregnancy ended in preterm labor, the authors concluded that in their region the incidence rate of premature delivery was 4.37 per cent (5.02 per cent in the rural and 3.78 in urban areas). In case of high parity, this value was twofold higher. Premature labors were not infrequently complicated by an early rupture of amniotic fluid sac (36.6 per cent), continuous waterless period (20.0 per cent), fetal asphyxia, etc. If indicated, perineotomy is to be applied to multiparous females and those with short inter partum periods. Intensive handling of preterm labor should be a method of choice in case of uterine inertia, infections, signs of fetal well-being risk, extragenital pathology. Rationalized management of premature labor reduces the incidence of hemorrhages, pathologic parturition and the rate of perinatal mortality.
