Background: Preterm premature rupture of membranes is defined as rupture of fetal membrane before onset of labour at less than 37 completed weeks of gestation and after 28 weeks of gestation. Incidence ranges from 3-10% of all deliveries. Preterm premature rupture of membrane is one of the important causes of preterm birth can result inhigh perinatal morbidity and mortality. Preterm premature rupture of membranes complicates 3% of pregnancies and leads to one third of preterm birth. Preterm delivery affects one in 10 birth in USA and even greater birth in developing continues and causes 40-75% neonatal death. There are numerous risk factors for preterm premature rupture of membrane such as maternal, socioeconomic class, infection at early gestational age and associated co-morbid condition. Both mother and fetus are at greater risk of infection after preterm premature rupture of membrane.The fetal and neonatal morbidity and mortality risks are significantly affected by severity of oligohydrominos, duration of latency and gestation at preterm premature rupture of membrane. The objective is to study perinatal outcome in preterm premature rupture of membrane.Methods: This is a prospective study conducted in Mahathma Gandhi Memorial Government Hospital attached to K. A. P. V. Government Medical College, Trichy, Tamil Nadu, India. This is a tertiary health centre. This study has been conducted from January 2018 to June 2018.Results: Incidence of PPROM ranges from 3.0-10.0% of all deliveries. PPROM complicates approximately 3% of pregnancies and leads to one third of preterm birth.Conclusions: In present study most of newborn had better 5min Apgar especially late preterm group. In present study RDS was common in early preterm group and hyper bilirubinaemia common in late preterm group. In current study most of patients delivered vaginally compared to 36% of LSCS.
