RESUMEN
OBJECTIVE: To compare the proportion of developmental delay in early complex cardiac surgery (CCS) survivors with and without gastrostomy tube feeding (GTF). To explore acute care predictors of GTF that might help improve care in CCS survivors. STUDY GROUP: This comparison study of 2 groups within an inception cohort included 334 CCS survivors after cardiopulmonary bypass at ≤6 weeks of age (2005-2012) who did not require extracorporeal membrane oxygenation or heart transplantation. Children were assessed at 21 ± 3 months with the Bayley Scales of Infant and Toddler Development-Third Edition and the Adaptive Behavior Assessment System-Second Edition: general adaptive composite score. Delay was determined by scores >2 SD below mean. The χ(2) test compared groups. Predictors of GTF were analyzed using multiple logistic regression analysis, results expressed as OR with 95% CI. RESULTS: Of the survivors, 67/334 (20%) had GTF any time before the 21-month assessment. Developmental delays in children with GTF were cognitive in 16 (24%), motor in 18 (27%), language in 24 (36%) vs without GTF in 7 (3%), 8 (3%), and 32 (12%), respectively (P < .001). Gastrostomy group had almost 8 times the number of children delayed on the general adaptive composite score. Independent OR for GTF are presence of a chromosomal abnormality, OR 4.6 (95% CI 1.8, 12.0) (P = .002), single ventricle anatomy, OR 3.4 (95% CI 1.7, 6.8) (P < .001), total postoperative days of open sternum, OR 1.15 (95% CI 1.1, 1.3) (P = .031), and total number of hospital days at CCS, OR 1.03 (95% CI 1.1, 1.04) (P = .002). CONCLUSIONS: GTF identifies CCS survivors at risk for delay, who would benefit from early developmental intervention. The described mostly nonmodifiable predictors may guide counseling of these children's families.

OBJECTIVE: To characterize the epidemiology of and identify risk factors for neonatal cardiac surgery-associated acute kidney injury (CS-AKI) and determine its impact on clinical outcomes. STUDY DESIGN: Using secondary analysis of data from an ongoing multiprovincial prospective cohort study, we studied 264 neonates undergoing complex cardiac repair. CS-AKI was defined based on the Acute Kidney Injury Network (AKIN) definition. We used regression modeling and survival analysis (adjusting for covariates) to evaluate associations. RESULTS: CS-AKI occurred in 64% of the neonates in our study cohort. Lower age, longer cardiopulmonary bypass time, hypothermic circulatory arrest, type of repair, lower preoperative serum creatinine (SCr) level, lower gestational age, and preoperative ventilation were independent risk factors for developing CS-AKI. Neonates with CS-AKI had longer times to extubation, intensive care discharge, and hospital discharge, after adjusting for covariates. Mortality was significantly increased in neonates with AKIN stage 2 or higher CS-AKI. The neonates with CS-AKI had a lower z-score for height at 2-year follow-up and were seen by more specialists. CONCLUSION: Neonatal CS-AKI is common and independently predicts important clinical outcomes, including mortality. Many risk factors are similar to those in older children, but some are unique to neonates. The observation that lower baseline SCr predicts CS-AKI merits further study. The AKIN definition, based on preoperative SCr value, is a reasonable method for defining CS-AKI in neonates. Many previous studies of CS-AKI have excluded neonates; we suggest that future intervention studies on approaches to reducing CS-AKI incidence and improving outcomes should include neonates.
