Background: Recently, the use of extracorporeal membrane oxygenation (ECMO) in noncardiac surgery, such as thoracic surgery, has increased. However, there have been no studies on the mortality and incidence of intraoperative cardiac arrest with or without ECMO during thoracic surgery. Methods: Between January 2011 and October 2018, 63 patients received ECMO support during thoracic surgery. All patients who applied ECMO from starting at any time before surgery to the day of surgery were included. Patients were divided into the emergency ECMO group and the non-emergency ECMO group according to the timing of ECMO. We compared the factors related to 30 day mortality using Cox regression analysis. Results: The emergency ECMO and non-emergency ECMO groups comprised 27 and 36 patients, respectively. On the operation day, cardiopulmonary resuscitation (CPR) was a very important result, and only occurred in the emergency ECMO group (n = 20, 74.1% vs. 0%, p < 0.001). The most common cause of ECMO indication was the CPR in the emergency ECMO group and respiratory failure in the non-emergency ECMO group. There were significant differences in 30 day mortality between the emergency ECMO group and the non-emergency ECMO group (n = 12, 44.4% vs. n = 3, 8.3%, p = 0.001). The Kaplan–Meier analysis curve for 30 day mortality showed that the emergency ECMO group had a significantly higher rate of 30 day mortality than the non-emergency ECMO group (X² = 14.7, p < 0.001). Conclusions: A lower incidence of intraoperative cardiac arrest occurred in the non-emergency ECMO group than in the emergency ECMO group. Moreover, 30 day mortality was associated with emergency ECMO.

Background: Extracorporeal membrane oxygenation (ECMO) as intraoperative cardiorespiratory support during lung transplantation is well known, but use for other types of surgery are limited. To assess risk factor for mortality after high-risk thoracic surgery and feasibility of ECMO, we reviewed.

Methods: This study was an observational study. Between January 2011 and October 2018, 63 patients underwent thoracic surgery with ECMO for severe airway disease, pulmonary insufficiency requiring lung surgery, and other conditions.

Results: In all, 46 patients remained alive at 30 days after surgery. The mean patient age was 50.38 ± 16.16 years. ECMO was most commonly used to prevent a lethal event (34 [73.9%]) in the Survival (S) group and rescue intervention (13 [76.5%]) in the Non-survival (N) group. In all, 11 patients experienced arrest during surgery (S vs N: 2 [4.3%] vs 9 [52.9%], p ≤0.001). The multivariate analysis revealed that arrest during surgery (odds ratio [OR], 24.44; 95% confidence interval [CI], 1.82–327.60; p = 0.016) and age (OR, 7.47; 95% CI, 1.17–47.85; p = 0.034) were independently associated with mortality.

Conclusions: ECMO provides a safe environment during thoracic surgery, and its complication rate is acceptable except for extracorporeal cardiopulmonary resuscitation (ECPR).

Massive pulmonary haemorrhage can spoil the entire lung and block the airway in a short period of time due to severe bleeding, which quickly leads to death. Alveolar lavage is an effective method for haemostasis and airway maintenance. However, patients often cannot tolerate alveolar lavage due to severe hypoxia. We used extracorporeal membrane oxygenation (ECMO) to overcome this limitation in a patient with massive pulmonary haemorrhage due to severe trauma and succeeded in saving the life by repeated alveolar lavage.

A 22-year-old man sustained multiple injuries in a motor vehicle accident and was transferred to our emergency department. On admission, he had a slight cough and a small amount of bloody sputum; computed tomography revealed multiple fractures and mild pulmonary contusion. At 37 h after admission, he developed severe chest tightness, chest pain, dizziness and haemoptysis. His oxygen saturation was 68%. Emergency endotracheal intubation was performed, and a large amount of bloody sputum was suctioned. After transfer to the intensive care unit, he developed refractory hypoxemia and heparin-free venovenous ECMO was initiated. Fibreoptic bronchoscopy revealed diffuse and profuse blood in all bronchopulmonary segment. Bleeding was observed in the trachea and right bronchus, and repeated alveolar lavage was performed. On day 3, the patient’s haemoptysis ceased, and ECMO support was terminated 10 d later. Tracheostomy was performed on day 15, and the patient was weaned from the ventilator on day 21.

Alveolar lavage combined with ECMO can control bleeding in trauma-induced massive pulmonary haemorrhage, is safe and can be performed bedside.
