Morbidity and mortality profile of late preterm neonates as compared to term neonates from a tertiary care centre in Mysore, India
Keywords:Late preterm neonates, Morbidity and mortality
Background: Prematurity is a major cause of neonatal mortality and morbidity. Most of the studies are focused on outcomes among preterm neonates less than 34 weeks gestation which has the highest mortality and morbidity. The main objective was to study the morbidity and mortality pattern of late preterm neonates as compared to term neonates.
Methods: Neonates delivered at Cheluvamba hospital Mysore, India from March 2014 to September 2014 were subjected to gestation assessment. Gold standard for gestational assessment was early obstetric ultrasound (6-12 weeks). In the absence of which, the gestation was calculated from the clinical assessment of gestation by expanded new Ballard score. The enrolled babies were divided into two groups: Study group: Gestational age 34 0/7 to 36 6/7 weeks (Late Preterm) and Comparison group: Equal number of term (above 36 weeks 6 days of gestation and below 42 weeks of gestation) neonates born in our hospital during the study period. After including cases, details were entered in predesigned proforma which included detailed maternal history for risk factors and detailed natal and postnatal history for complications and late preterm were compared with term neonates.
Results: A total of 110 late preterm neonates were compared with 110 term neonates. As compared to term neonates, late preterm neonates were more at risk for need of resuscitation (p=0.013), need for nutritional and supportive care (p=0.000), respiratory distress (p=0.000), birth asphyxia (p=0.032), early onset sepsis (p=0.001), neonatal jaundice (p=0.001), hypothermia (p=0.000) and feeding difficulties (p=0.000). They also had prolonged duration of stay in hospital (p=0.000) and also mortality was more in late preterm neonates as compared to term neonates (p=0.002).
Conclusions: Late preterm neonates have a higher risk for morbidity and mortality as compared to term neonates and hence, need special attention.
