Safety and Feasibility of Early Physical Therapy for Patients on Extracorporeal Membrane Oxygenator: University of Maryland Medical Center Experience*

Objectives: To examine the feasibility and safety of mobilizing patients while on extracorporeal membranous oxygenation support. Design: Retrospective cohort study. Setting: Medical and Surgical ICUs in a large tertiary care hospital in the United States. Patients: Adults supported on extracorporeal membranous oxygenation from January 2014 to December 2015. Measurements and Main Results: We reviewed the medical records from physical therapy, perfusion, and intensivists to obtain the number and type of physical therapy interventions and discharge status; extracorporeal membranous oxygenation type and description of support, cannulation sites; and risk management details of adverse effects, if any. Of 254 patients supported on extracorporeal membranous oxygenation, 167 patients (66.7%) received a total of 607 physical therapy sessions while on extracorporeal membranous oxygenation support. In this cohort, 134 patients (80.2%) had at least one femoral cannula during physical therapy intervention. Sixty-six of the 167 patients (39.5%) were supported on extracorporeal membranous oxygenation with bifemoral cannulas, and 44 (26.3%) were on veno-arterial extracorporeal membranous oxygenation. A dual lumen catheter was only used in five cases. Twenty-five patients (15%) (13 bifemoral cases) participated in standing or ambulation activities. Seventy-five patients (68.8%) who were successfully weaned from extracorporeal membranous oxygenation were discharged to a rehabilitation facility; 26 patients (23.8%) went home.
