AbstractPrognostic factors influencing survival in 235 very low birthweight prematures (< or = 1500 g) born between 1986 and 15.11. 1993 at the Department of Obstetrics and Gynaecology, University Hospital of Cologne, were retrospectively evaluated. Chromosomal anomalies and severe congenital malformations were excluded. Of 180 singletons 84 were classified as appropriate-for-gestational-age (AGA) and 96 as small-for-gestational-age (SGA). By interrogating the attending paediatricians data regarding the early development of 62/65 surviving singletons born between 1986 to 1990 were recorded (follow-up rate 95%). Survival was significantly correlated to singleton pregnancy (p < 0.05), female sex (p = 0.001) and in the AGA-prematures to prenatal corticoid prophylaxis. With similar mean birthweight SGA-singletons showed a three weeks higher mean gestational age; the mortality showed an inverse correlation to birthweight and gestational age being 11% higher in the AGA-group compared with the SGA-group (32% versus 21%). At the age of between 11 months and 6 years severe handicaps and developmental retardations were found more often in previous AGA-prematures (6/26) than in previous SGA-prematures (4/36); type and degree of later handicap were not correlated to birthweight. According to our results survival rates of very low birthweight prematures are strongly influenced by singleton pregnancy, by fetal sex, by gestational age and in the AGA-group by prenatal corticoid prophylaxis; mortality shows an inverted correlation to birthweight and gestational age, whereas the later prognosis of survivors does not seem to be influenced by birthweight or gestational age.
