RESUMO
OBJECTIVE: To evaluate the short-term outcomes and safety of therapeutic hypothermia (TH) for neonatal encephalopathy in preterm infants at 34-35 weeks of gestation. STUDY DESIGN: A matched retrospective cohort study of 20 preterm infants at 34-35 weeks of gestation and 40 infants at 36 weeks of gestation or more who received TH between the years 2015-2021. RESULT: Short-term outcomes of preterm infants at 34-35 weeks of gestation who received TH were comparable with infants at 36 weeks or more of gestation who received TH regarding seizures, intraventricular hemorrhage, blood transfusions, subcutaneous fat necrosis, brain injury on magnetic resonance imaging, and mortality. These findings were consistent when short-term outcomes were adjusted for birthweight. CONCLUSION: TH in preterm infants at 34-35 weeks of gestation is feasible and safe in our study population.

OBJECTIVE: Identify feeding supports required among infants with neonatal encephalopathy and determine growth trajectories to 3 years. STUDY DESIGN: Single-center retrospective cohort study of 120 infants undergoing therapeutic hypothermia. Logistic regression and stratified analyses identified whether clinical factors, EEG-determined encephalopathy severity, and MRI-based brain injury predict feeding supports (nasogastric tube, oral feeding compensations) and growth. RESULTS: 50.8% of infants required feeding supports in the hospital, decreasing to 14% at discharge. Moderate-to-severe encephalopathy and basal ganglia injury predicted feeding support needs. Yet, 35% of mildly encephalopathic infants required gavage tubes. Growth trajectories approximated expected growth of healthy infants. CONCLUSION: Infants with neonatal encephalopathy-even if mild-frequently experience feeding difficulties during initial hospitalization. With support, most achieve full oral feeds by discharge and adequate early childhood growth. Clinical factors may help identify infants requiring feeding support, but do not detect all at-risk infants, supporting routine screening of this high-risk population.
