Mortality and respiratory failure in a pediatric burn population

Abstract 

A 9-year retrospective review of 1,242 admissions to a tertiary burn center identified 137 patients who were intubated and ventilated for a critical airway or pulmonary problem. These patients varied in age from 2 months to 18 years with an average total body surface area (TBSA) burn of 55%. We evaluated this group for evidence of respiratory failure (ARF) as defined by the respiratory failure index (RFI) (PaO₂/FIO₂ < or = 300). While only 23% of admissions to the burn center were related to flame burns, these injuries accounted for 82% of children who had ARF. Forty-two percent of these intubated children had abnormalities on their admission chest x-ray and 61% of this cohort developed evidence of ARF as defined by the RFI. The development of sepsis along with ARF regardless of TBSA involvement doubles the mortality of ARF alone. Early burn wound excision and grafting is critically important to prevent the late complication of sepsis. We carefully monitor ventilator settings to insure low peak inspiratory pressures, allowing relative hypercapnia and avoiding hyperoxia. Despite an increased number of admissions and critically injured children, we have not seen an increase in morbidity and have had a 53% reduction in mortality in the last 2 years with these techniques. We believe this management offers the best outcome for the pediatric burn victim and would recommend this strategy to other centers dealing with these severely injured children.
