OBJECTIVE: Neonatal encephalopathy remains a major cause of infant mortality and neurodevelopmental impairment. Infection may exacerbate brain injury and mitigate the effect of therapeutic hypothermia (TH). Additionally, infants with sepsis treated with TH may be at increased risk of adverse effects. This study aimed to review the clinical characteristics and outcomes for infants with sepsis treated with TH.
DESIGN AND SETTING: Retrospective cohort study of infants treated with TH within Australia and New Zealand.
PATIENTS: 1522 infants treated with TH, including 38 with culture-positive sepsis from 2014 to 2018.
INTERVENTION: Anonymised retrospective review of data from Australian and New Zealand Neonatal Network. Infants with culture-positive sepsis within 48 hours were compared with those without sepsis.
MAIN OUTCOME MEASURES: Key outcomes include in-hospital mortality, intensive care support requirements and length of stay.
RESULTS: Overall the rate of mortality was similar between the groups (13% vs 13%). Infants with sepsis received a higher rate of mechanical ventilation (89% vs 70%, p=0.01), high-frequency oscillatory ventilation (32% vs 13%, p=0.003) and inhaled nitric oxide for persistent pulmonary hypertension (38% vs 16%, p<0.001). Additionally, the sepsis group had a longer length of stay (20 vs 11 days, p<0.001).
CONCLUSION: Infants with sepsis treated with TH required significantly more respiratory support and had a longer length of stay. Although this may suggest a more severe illness the rate of mortality was similar. Further research is warranted to review the neurodevelopmental outcomes for these infants.
