Abstract
Introduction
The mobilization and ambulation of patients with severe cardiogenic shock supported with peripheral veno-arterial extracorporeal membrane oxygenation (pVA-ECMO) and concomitant femoral intra-aortic balloon pump (IABP) support is not well-described. This technical paper describes an ambulation protocol to prevent deconditioning in this critically ill patient population.
Methods
A protocol for the ambulation of patients with pVA-ECMO and concomitant IABP support was created in December 2022 and implemented at a single center. To initiate ambulation, patients were initially placed in a vertical position utilizing the VitalGo Total Lift Bed (VitalGo Systems, Miramar, FL) with mechanical circulatory support device monitoring performed by a critical care multidisciplinary team. Retrospective analysis of successfully ambulated patients was performed from December 2022 to January 2024.
Results
A total of 35 patients out of 112 patients with ECMO support were ambulated in the study period. Four of these patients had pVA-ECMO with concomitant IABP support with this cohort completing a total of 11 sessions during the study period. Patients ambulated an average of 200 feet per session without any adverse events, including cannula and balloon pump migration or displacement. Three of the four patients studied were either bridged to an advanced therapy including orthotopic heart transplant or durable left ventricular assist device or were discharged.
Conclusion
A protocol for ambulation of CS patients with pVA-ECMO support and concomitant femoral IABP support is feasible and can safely be implemented in this critically ill patient population. Further multicenter studies are necessary to determine the overall impact of ambulation on patient outcomes.
