OBJECTIVE: Poor growth is a common complication in @entity1 with @entity299 . There has been much focus on low birth weight as having increased risk of adverse outcomes following neonatal heart surgery. In this study, we examined whether preoperative nutritional status, measured by admission weight-for-age z score, was associated with postoperative clinical outcome. DESIGN: Retrospective case series. SETTING: Pediatric Cardiac ICU at the Royal Brompton Hospital. @entity1 : Neonates undergoing surgery for @entity299 . Those undergoing ductus arteriosus ligation alone were excluded. @entity1 with coexisting noncardiac morbidity were excluded. Outcome variables included prevalence of @entity260 (including @entity295 , delayed chest closure, @entity8 , and @entity3166 ), duration of ventilation, intensive care stay, postoperative mortality, and mortality at 1 year after surgery. INTERVENTIONS: None. Analysis of @entity1 data only. MEASUREMENTS AND MAIN RESULTS: Two hundred forty-eight neonates fulfilled the entry criteria. Median (interquartile range) age was 7 days (2-15 d), median (interquartile range) weight was 3.3 kg (2.91-3.6 kg), and median weight-for-age z score was -0.77 (-1.44 to 0.01). Twenty-eight @entity1 (11%) had a weight-for-age z score of less than -2. There was no evidence that @entity1 with lower weight-for-age z score had less severe surgery as measured by the Risk Adjustment for Congenital Heart Surgery 1 score. In multivariable regression analysis, the weight-for-age z at admission had strong correlation with the number of days free of respiratory support (invasive and noninvasive ventilation) at 28 days (p < 0.0001) and with all-cause mortality at 1 year (p = 0.001). CONCLUSIONS: Poor nutritional status as measured by weight-for-age z is associated with adverse short- and long-term outcomes in neonates undergoing surgery for @entity299 .
