title: Outcome of very low birth weight infants with abnormal antenatal Doppler flow patterns: a prospective cohort study.
abstract: BACKGROUND
  Fetal growth restriction and abnormal Doppler flow studies are commonly associated. Neonatal outcomes are not well known particularly in developing countries, where the burden of the disease is the highest.
  
  
  OBJECTIVE
  To determine outcomes of preterm infants with history of absent/reversed end-diastolic umbilical artery Doppler flow (AREDF) vs. infants with forward end-diastolic flow (FEDF).
  
  
  METHODS
  Cohort study.
  
  
  METHODS
  Tertiary care perinatal center in India.
  
  
  METHODS
  103 AREDF very low birth weight (<1500 gm) (VLBW) infants and 117 FEDF VLBW infants were prospectively enrolled.
  
  
  RESULTS
  At 40 weeks adjusted post-menstrual age, AREDF vs. FEDF group had a higher risk for death in the NICU (12% vs. 1%), respiratory distress syndrome (33% vs. 19%), and cystic periventricular leukomalacia (12% vs. 1%). At 12-18 months corrected age, AREDF vs. FEDF group had a trend towards increased risk for cerebral palsy (7% vs. 1%, P=0.06). After logistic regression analysis, adjusting for confounders, AREDF was independently associated only with mortality in the NICU.
  
  
  CONCLUSIONS
  AREDF is an independent predictor of adverse outcomes in preterm infants in a developing country setting.
