Abstract

Background:

Asphyxiated infants treated with therapeutic cooling can have persistent oral feeding difficulty because of involvement of neural pathways in the brainstem, cortex, and basal ganglia. The goal is to predict the composite adverse outcome of death or persistent oral feeding difficulty using precooling/cooling attributes, and the severity and distribution of hypoxic–ischemic lesions, especially brainstem lesions on post-cooling brain magnetic resonance imaging (MRI).

Methods:

Retrospective review of 86 asphyxiated infants cooled from January 2006 to August 2014. Persistent feeding difficulty was defined as needing feeding support (gastrostomy tube (g-tube) or home gavage feeds) after discharge. Clinical and laboratory risk factors, and the brain MRI abnormalities including the presence of brainstem lesions were compared between infants with and without adverse outcome using univariate analysis. Significant variables were then analyzed in a stepwise logistic regression (LR) model.

Results:

Infants with adverse outcome (n = 31, 4 died pre-discharge) had longer hospital stay (26 days, interquartile range (IQR) 19–43 vs. 13 days, IQR 9–20; p < 0.01) and reached goal enteral feeds (oral/gavage) later (11 days vs. 8 days, p < 0.01) compared to 55 infants discharged on full oral feeds. The former infants were more likely to have cord pH ≤ 7.15, severely abnormal neurological examination, bleeding diathesis, continued need for ventilation, and positive MRI findings including brainstem lesions. In LR analysis, brainstem lesions on MRI (p = 0.00, odds ratio 19, 95% confidence interval 4–85) was independently associated with the adverse outcome.

Conclusions:

Brainstem involvement on post-cooling brain MRI was predictive of adverse outcome. Early identification of these infants may facilitate discussion of home feeding plans between clinicians and parents earlier, thereby potentially reducing the length of hospital stay.
