Abstract
Over the past decade, the use of extracorporeal membrane oxygenation (ECMO) has increased exponentially, from approximately 30–40 patients per year in the United States 20 years ago, to over 2,000 per year currently, and rising.1 The increased utilization of ECMO has resulted from improved cannulation techniques, including percutaneous approach, as well as advances in the technology of the pumps, oxygenators, and cannulas. Despite these features, however, choosing appropriate candidates and managing their daily care can be extremely challenging. What follows is an in-depth discussion of the indications for venoarterial (VA) ECMO in adult patients affected by cardiac disease, the manner of its application, the physiology underlying the care for these patients, and the assessment and treatment of complications, including ethical and organizational issues. More in-depth material and information are provided in the Extracorporeal Life Support Organization (ELSO) 5th Edition Red Book.2 Furthermore, the recent ELSO indications about ECLS and cannulation nomenclature will be followed in this guideline.3,4 Decision Making in Adult VA ECMO for Acute Cardiac Failure VA ECMO may support patients for days or weeks as a “bridge-to-decision” that includes weaning after recovery of cardiac function, transplantation, long-term mechanical circulatory support (MCS), and withdrawal in the case of futility. Dedicated documents for the use of VA ECMO in the setting of cardiac arrest and postcardiotomy in adult patients are addressed by additional ELSO guidelines and as joint society position paper (expert consensus of EACTS/ELSO/STS/AATS).5 Indications Specific physiologic goals, monitoring, and patient selection. Cardiogenic shock suitable for ECMO is generally characterized by systemic systolic pressure less than 90, urine output 3) (normal is 5, shock is 2): O2 delivery is arterial oxygen content (normal 20 ml/dl) times cardiac output (normal 30 dl/m2/min). In VA ECMO access, addressing the goal is easy because the cardiac output is the ECMO flow and the arterial hemoglobin saturation is 100%, so content is easily calculated, knowing the hemoglobin concentration (normal 15 g/dl). In VA ECMO, the drainage blood saturation (the SVO2) measures the DO2:VO2 ratio, and SVO2 is measured continuously. If the arterial saturation is 100% and the venous sat is 80%, the ratio is 5:1. So, adjusting flow and hemoglobin to maintain SVO2 over 66% assures that the goal of DO2/VO2 > 3 is met. Additional details are described in the Red Book chapter on physiology.2 Table 1. - Clinical Features of Cardiogenic Shock and Defined Contemporary Trials and Guidelines Clinical Trial/Guidelines
