Isolated Lung Ventilation With Tracheostomy Using Two Intubation Tubes for Severe Endotracheal Hemorrhage Due to Pulmonary Contusion.

A 72-year-old man presented with severe pulmonary contusions and multiple traumas, including aortic injury, pelvic fracture, and renal injury. The patient required multidisciplinary treatment, including transcatheter arterial embolization, thoracic endovascular aortic repair, right lung upper lobe partial resection, and massive transfusion. During the initial treatment, the patient experienced respiratory failure due to endotracheal bleeding, and we attempted isolated lung ventilation with a 37 Fr double-lumen endotracheal intubation tube.

Two cases of cryptogenic life-threatening hemoptysis - identification and management of bleeding point.

Cases: Case 1: A 63-year-old woman was referred for coughing blood. Although cardiorespiratory dynamics were stabilized by artificial respiration under sedation, severely poor ventilation developed from asphyxia associated with massive respiratory tract hemorrhage. One-lung ventilation was temporarily secured by endotracheal tube insertion into the left main bronchus just prior to cardiopulmonary arrest.
