ABSTRACT To determine whether neurodevelopmental outcomes at the age of 2 years accurately predict school readiness in children who survived respiratory distress syndrome after preterm birth.
Our cohort included 121 preterm infants who received surfactant and ventilation and were enrolled in a randomized controlled study of inhaled nitric oxide for respiratory distress syndrome. Abnormal outcomes at the age of 2 years were defined as neurosensory disability (cerebral palsy, blindness, or bilateral hearing loss) or delay (no neurosensory disability but Bayley Scales of Infant Development mental or performance developmental index scores <70). School readiness (assessed at a mean age of 5y 6mo, SD 1y) was determined using neurodevelopmental assessments of motor, sensory, receptive vocabulary, perceptual, conceptual, and adaptive skills.
The mean birthweight of the cohort (57 males, 64 females) was 987g (SD 374), and the mean gestational age was 27.3 weeks (SD 2.6). At the age of 2 years, the neurodevelopmental classification was 'disabled' in 11% and 'delayed' in 23%. At the age of 5 years 6 months, intensive special education was required for 11% and some special education for 21%. Disability and delay at the age of 2 years were 92% and 50% predictive of lack of school readiness respectively, whereas only 15% of children who were normal at the age of 2 years were not school ready at the later assessment. Children with delay at 2 years were more likely to need special education if they were socially disadvantaged.
Without preschool developmental supports, preterm survivors living in poverty will require more special education services.

    ABSTRACT: In the past 20 years, many advances (e.g., maternal steroids and surfactant) have changed the course of neonatal medicine. As a result, extremely preterm infants survive medical complications that were previously fatal. Once they are discharged from the neonatal intensive care unit, preterm infants may continue to experience a spectrum of medical and developmental challenges, and their families are faced with the potentially daunting task of nurturing a vulnerable child. Families may be referred to multiple systems of care, including primary care physicians, pediatric subspecialists, and early intervention services. The ultimate goal for preterm infants is to optimize their motor, communicative, social-emotional, and adaptive development as well as to promote their learning at home, at school, and in the community. As children transition to school, key indicators of their functional status include the amount of developmental, educational, habilitative, and behavioral supports they require to participate in learning activities with their peers. Success may be measured by whether preterm infants are ready for large-group learning with peers and the extent of supports required to make this important transition. The purpose of this review is to describe what is known about certain indicators of school readiness in preterm infants, including neurodevelopmental impairments, social-emotional skills, and social factors. We conclude with guidelines for using this transition as an important indicator of developmental trajectories that may help us to better understand risk and resilience in this vulnerable population of children. © 2011 Wiley Periodicals, Inc.

    ABSTRACT: The aims of the study were to assess the long-term safety and compare neurodevelopmental outcomes in school-age children born prematurely who received inhaled nitric oxide or placebo during the first week of life in a randomized, double-blinded study. Children treated with inhaled nitric oxide had previously been shown to have decreased intraventricular haemorrhage and periventricular leukomalacia as newborns and decreased cognitive impairment at 2 years (L.W. Doyle and P.J. Anderson. (2005) Arch Dis Child Fetal Neonatal Ed, 90, F484-F8). It is follow-up study of medical outcomes, neurodevelopmental assessment and school readiness in 135 of 167 (81%) surviving premature infants seen at 5.7±1.0 years. Compared to placebo-treated children (n=65), iNO-treated children (n=70) demonstrated no difference in growth parameters, school readiness or need for subsequent hospitalization. However, iNO-treated children were less likely to have multiple chronic morbidities or technology dependence (p=0.05). They also had less functional disability (p=0.05). These results demonstrate the long-term safety of iNO in premature infants. Furthermore, iNO treatment may improve health status by decreasing the incidence of severe ongoing morbidities and technology dependence and may also decrease the incidence of educational and community functional disability of premature infants at early school age.
