Here is a brief summary of the article: The case report describes a case of a 52-year-old man with a complete transection of the right main bronchus after a traffic accident. The patient had severe hypoxemia that did not respond to intubation and mechanical ventilation. Veno-venous extracorporeal membrane oxygenation (VV-ECMO) was used to ensure sufficient oxygenation during surgical repair. After successful bronchial anastomosis, inhaled nitric oxide (iNO) was administered postoperatively to improve the ventilation-perfusion ratio. ECMO was discontinued on the second postoperative day and iNO on the fourth postoperative day. The patient was weaned from mechanical ventilation on the thirteenth postoperative day and discharged home after complete recovery. The case suggests that VV-ECMO may be useful in traumatic bronchial transection repairs with refractory hypoxemia, and iNO may help manage perioperative oxygenation.
