[Clinical analysis of preterm labor]

576 patients with preterm deliveries that occurred between the 22nd to 37th gestation weeks were undergone clinical analysis. The material was collected in the years 1995 to 1999 at Clinic of Obstetric and Perinatology of Pomeranian Academy of Medicine in Szczecin. In our study the rate of preterm delivery was 10.5%. Special attention was paid to mother's age, obstetrics history, socioeconomic, medical and psychogenic conditions of pregnant women, condition of infants, infant mortality and their birth-weight. The rate of premature preterm rupture of fetal membranes was 52.7%. The frequency of caesarean sections in our study in preterm births was about 50% like in other publications and the most important indication for them was amnionitis. In almost 40% the general state of infants was poor and medium. Almost 25% of preterm deliveries is connected with other systemic diseases during pregnancy.
