Abstract

OBJECTIVE: To compare neurodevelopmental outcomes in postnatal growth-restricted infants born <29 weeks with and without postnatal head-sparing (PHS).

STUDY DESIGN: We analyzed developmental outcomes at 2 years of age among postnatally growth-restricted infants with and without head-sparing. The primary outcome was Bayley III cognitive composite score; secondary outcomes included Bayley III motor composite score, moderate/severe cerebral palsy, gross motor functional classification scale level 2, and presence or absence of neurodevelopmental impairment (NDI).

RESULTS: Of 1098 infants evaluated at 18 to 22 months, 658 were postnatally growth restricted, of whom 301 had head-sparing. In the multivariate model including independent risk factors for poor growth and poor developmental outcome, infants with head sparing had higher adjusted motor composite scores (mean difference 4.65, P <0.01), but no differences in other neurodevelopmental outcomes.

CONCLUSION: PHS is associated with improved neurodevelopmental outcome in extremely preterm infants, specifically Bayley III motor scores, but whether beneficial effects of PHS persist later in life is unknown.
