Heparin-free adventitia pulmonary oxygenation in the treatment of trauma complicated with severe pulmonary infection: a case report

Abstract

The application of Venovenous (VV) extracorporeal membrane oxygenation (ECMO) in trauma and patients with severe bleeding tendency has been controversial. However, VV ECMO without anticoagulation contributes to reducing the risk of bleeding during ECMO maintenance. VV ECMO serves critical roles in therapy of patients with severe pulmonary infection and failure in conventional therapy. The common peripheral catheterization approach for VV ECMO is femoral vein-internal jugular vein catheterization, and bilateral femoral vein catheterization can also achieve the purpose of respiratory support for patients with limited cervical catheterization. In this case report, we described a patient with post-traumatic cervical spinal cord injury and severe pulmonary infection who was successfully treated with heparin-free intravenous ECMO.
