The comparison of perinatal outcomes in twin and singleton pregnancies delivered prematurely between 28 weeks and 36 weeks gestational age

Objective : To compare the perinatal outcomes in twin and singletone pregnancies delivered prematurely between 28 and 36 weeks gestational age. Methods : We studied 80 pairs of twin delivered between 28 weeks and 36 weeks gestational age at Eulji university hospital between January 1996 and October 2000. The perinatal morbidity and mortality in premature twin pregnancies were compared to those of premature singleton pregnancies (N=402). Results : The premature twin pregnancies had no significant differences of gestational age at delivery than those of singleton pregnancies, but significantly lower mean birth weight. In mean day of hospital stay, 1 and 5 min Apgar scores, there were no significant differences. There were no significant differences in the incidence of neonatal morbidity such as hyaline membrane disease, and retinopathy of prematurity, between the two groups. And also the perinatal mortality was not significantly different between the two groups. Conclusion : There were no significant differences in perinatal mortality and morbidity between the two groups.
