Extracorporeal Membrane Oxygenation in a Patient with Severe Inhalation Injury: Multidisciplinary Burn Team Care.

INTRODUCTION

Inhalation injury is a major risk factor for mortality in burn patients via 3 primary mechanisms: airway edema and obstruction, hypoxemic respiratory failure, and pneumonia. Currently, the mainstay of treatment is supportive care to include early intubation, lung-protective or high-frequency-percussive mechanical ventilation, nebulized heparin, and aggressive pulmonary toilet. Despite these treatments, a subset of these patients progress to severe acute respiratory distress syndrome (ARDS) for which rescue options are limited.

CASE PRESENTATION: A 31-year-old woman was found down in a house fire. On admission to the burn intensive care unit, she was diagnosed with grade 3 smoke inhalation injury. Cutaneous thermal injury was absent. By hospital day 2, she developed worsening hypoxemia and hypercapnia despite maximal ventilatory support. She was placed on veno-venous extracorporeal membrane oxygenation (ECMO). She received an average of 2.2 hours of direct rehabilitation a day and completed out-of-bed modalities over 90% of total hospital days. After 159 hours, she was decannulated, and by hospital day 18, she was discharged home on supplemental oxygen.

CONCLUSION

Current literature regarding ECMO in inhalation injury is limited, but a growing body of evidence suggests that treatment of severe smoke inhalation injury should include ECMO for those who fail conventional therapy.
