ECMO For Pediatric Cardiac Arrest Caused by Bronchial Rupture and Severe Lung Injury: a Case Report About a Life-threatening Rescue at an Adult ECMO Center

Background: Bronchial rupture in children is a rare but dangerous complication after chest trauma that has been associated with increased mortality. Veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) is reported as one of the treatments for this life-threatening complication. Case presentation A 4-year-old boy who suffered from bronchial rupture and traumatic wet lung complicated by cardiac arrest after chest trauma was admitted to an adult ECMO center. He had two cardiac arrests-one before and one during the operation. The total duration of cardiac arrest was 30 minutes. V-V ECMO was initiated because of severe hypoxia and carbon dioxide retention during the operation. ECMO was performed for 6 days, and mechanical ventilation lasted 11 days. On the 31st day after the operation, he recovered completely and discharged without neurological deficit. Conclusion: V-V ECMO can be considered for support in children with severe acute respiratory failure after bronchial rupture. In an emergency, V-V ECMO can be carried out effectively in a qualified and experienced adult ECMO center. But the application of ECMO in children is different from that in adults and requires more refined management.
