Objectives : To evaluate maternal and neonatal complications and pregnancy outcomes of twin pregnancies.
Materials and Methods : The retrospective analysis included data on the twin pregnancies delivered at
Ramathibodi Hospital between January 1995 and December 2000. The data retrieved from the medical
records included demographic data, complications of pregnancy, and maternal and neonatal outcomes.
Statistical analysis was performed.
Results : Of 374 twin pregnancies, 321 cases had completed medical records. Incidence of twin pregnancies
was 8.6 per 1,000 births. Most common maternal complication was preterm delivery (49.2%). Other maternal
complications were anemia (21.5%), pregnancy induced hypertension (13.4%), premature rupture of mem-
branes (10%), postpartum hemorrhage (5.6%) and antepartum haemorrhage (1.9%), respectively. Median
gestational age at delivery was 37 weeks. Most common route of delivery was caesarean section (58.3%).
Most common neonatal complication was low birth weight (62.3%). Perinatal mortality rate was 45 per 1,000
births. Prematurity was the most common cause of neonatal death. No neonatal death was found after 34
weeks of gestation.
Conclusion : Twin pregnancy has high maternal and neonatal complications, especially preterm delivery that
increases risk of significant neonatal morbidity and mortality.
