In this largest cohort of long-term follow-up to date, we have shown the overall risk of mortality varied according to the indication for the tracheostomy. We were unable to determine exact causes of death. The likelihood of being decannulated also correlates with the underlying indication for the tracheostomy.

Critically ill children are hypermetabolic and in negative NB. In this population, fat is used preferentially for oxidation and carbohydrate is utilized poorly. A high carbohydrate intake was associated with lipogenesis and less fat oxidation, a negative NB was associated with high oxidation rates for protein, and a high protein intake was associated with a positive NB.
