The most common cause of death due to the H1N1 subtype of influenza A virus (swine flu) in the 2009 to 2010 epidemic was severe acute respiratory failure that persisted despite advanced mechanical ventilation strategies. Extracorporeal membrane oxygenation (ECMO) was used as a salvage therapy for patients refractory to traditional treatment. At Legacy Emanuel Hospital, Portland, Oregon, the epidemic resulted in a critical care staffing crisis. Among the 15 patients with H1N1 influenza A treated with ECMO, 4 patients received the therapy simultaneously. The role of ECMO in supporting patients with severe respiratory failure due to H1N1 influenza is described, followed by discussions of the nursing care challenges for each body system. Variations from standards of care, operational considerations regarding staff workload, institutional burden, and emotional wear and tear of the therapy on patients, patients’ family members, and the entire health care team are also addressed. Areas for improvement for providing care of the critically ill patient requiring ECMO are highlighted in the conclusion.
Because of technological advancements and encouraging experiences during the 2009 influenza A (H1N1) epidemic, many critical care clinicians consider extracorporeal membrane oxygenation (ECMO) a reasonable strategy for managing patients with refractory hypoxemia when standardized therapies have failed. Although the literature remains unclear as to whether it should be considered a routine or a rescue strategy in the management of patients with severe acute respiratory distress syndrome, experts agree that ECMO therapy is most likely to result in positive outcomes and fewer complications when provided at regional ECMO centers. Some institutions have developed the expertise and resources required to provide this sophisticated therapy, but significantly more facilities may choose to send their patients to a tertiary ECMO center when they do not respond to usual care. This article provides information essential for health care teams who refer their patients to such centers. The clinical indications for, and the use of, ECMO therapy in the management of refractory hypoxemia is briefly reviewed, followed by a description of how ECMO works to provide gas exchange and tissue perfusion. The primary considerations for circuit management, hemodynamic support, and pulmonary care are described, and significant complications of the therapy are identified. The remainder of the article focuses on the patient care and preparatory activities that occur before and during ECMO initiation, so that health care teams, patients, and their families can be confident of an efficient, safe, and highly skilled transfer of care between institutions.
