The aim of this study was to estimate complications of pregnancy, indications to caesarean section, complications after caesarean operation and perinatal mortality of newborns who were delivered before the 37th week of gestation by caesarean section. The retrospective analysis of the total of 2693 deliveries (years 1991-2000) by caesarean section in the Department of Pregnancy and Labour Pathology in Pomeranian Academy of Medicine has been carried out. 590 women whose delivered before the 37th week of pregnancy have been chosen for subsequent examination. The patients have been divided into three groups: group I--patients with pregnancy completed before the 28th week, group II--patients with pregnancy completed between 29th and 32nd week, and group III--patients with pregnancy completed between the 33rd and 36th week. Obstetrical anamnesis, complications of pregnancy, indications to caesarean section and postoperative complications as well as newborns perinatal mortality have been analysed. Among women who experienced abortions, premature deliveries caesarean section a higher rate of caesarean section during subsequent premature delivery was stated. The increase of caesarean sections rate in premature deliveries after the 29th week of gestation is associated with a considerable decrease in newborns, mortality.
