Abstract
The anticoagulation and coagulopathy associated with venovenous extracorporeal membrane oxygenation (VV-ECMO) lead to concern for increased risks of tracheostomy. The purpose of this study is to evaluate the safety of tracheostomy in patients on VV-ECMO. Patients admitted between November 2015 and January 2019 to a dedicated intensive care unit for VV-ECMO were reviewed retrospectively. 96 patients underwent tracheostomy. Tracheostomy was performed percutaneously in 51 patients, open in 24, and hybrid in 21. 28 patients had postprocedure bleeding which was from the tracheostomy site in 13, the airway in 13, and both in 2. 6 patients had major tracheostomy site bleeding and 3 patients had major airway bleeding. 7 patients had minor tracheostomy site bleeding, 10 patients had minor airway bleeding, and 2 patients had minor bleeding at both. Bleeding complications were more common following percutaneous tracheostomy. Being on anticoagulation prior to tracheostomy was protective. Bleeding following tracheostomy in VV-ECMO is common with higher bleeding rates observed for those done percutaneously. Most complications were minor. Tracheostomy in patients on VV-ECMO appears safe.
