Anesthetic management of lung transplantation in a patient with end-stage COVID-19 pneumonia: a case report

ABSTRACT

Rationale The COVID-19 pandemic is spreading around the world and the leading cause of death is rapidly progressive respiratory failure because of lung damage and consolidation. Lung transplantation is the last line of treatment for chronic end-stage lung diseases. There were several cases of lung transplantation reported in patients with COVID-19 pneumonia. However, anesthetic management of lung transplantation in this subpopulation is rare. We report the anesthetic and perioperative management of lung transplantation in a patient with COVID-19 pneumonia. Patient concerns A 70-year-old man with a 7-day history of fever was diagnosed with COVID-19 pneumonia. His throat swab was positive for COVID-19, but negative for other common viruses. Chest radiography showed multiple inflammatory foci in both lungs. By day 5, he presented respiratory distress. Computed tomography (CT) scan showed progressive deterioration of both lungs. Starting on day 7, SARS-CoV-2 RNA in bronchoalveolar lavage samples were continuously negative. However, his lung condition deteriorated. By day 17, a veno-venous extracorporeal membrane oxygenation (ECMO) was initiated. After 10 days of ECMO support, the patient's lung condition did not improve. CT scan revealed bilateral parenchymal consolidation with pulmonary fibrosis and hydrothorax. Diagnosis Irreversible lung function loss induced by COVID-19 pneumonia. Interventions: Bilateral transplantation was performed because the patient's lung condition did not improve and CT scan revealed parenchymal consolidation with pulmonary fibrosis after 10 days of ECMO support. Thirty-six hours after the surgery, ECMO was discontinued. A percutaneous transluminal coronary angioplasty and a stent implantation were performed because of acute coronary syndrome and myocardial ischemia 4 days postoperatively. Outcomes: The patient remained hospitalized because of requirements for intermittent assisted ventilation via tracheostomy. Lessons This case further supports the consideration that lung transplantation can potentially be the successful therapy for these patients who have developed irreversible lung function lose due to COVID-19 pneumonia. However, most critical patients with COVID-19 are older individuals with various comorbidities, which present new anesthetic challenges.
