Management of ECMO Patients in the ICU

Introduction to ECMO Management

The Extracorporeal Life Support Organization (ELSO) recommends a standardized, multidisciplinary approach for ECMO patients in the ICU, focusing on five critical domains: neurological monitoring, hemodynamic optimization, prevention and management of acute brain injury, anticoagulation management, and systematic prognostication, as guided by the 2024 ELSO consensus guidelines 1, 2, 3

Protocolized neurological monitoring is essential as acute brain injury (ABI) occurs in 16% of all ECMO patients, with significantly higher rates in VA-ECMO (19%) compared to VV-ECMO (10%), according to the Critical Care journal 1, 2, 4
The American College of Critical Care Medicine recommends performing comprehensive neurological examinations on all ECMO patients, assessing consciousness, cognition, brainstem function, and motor function at regular intervals, although this specific recommendation is from Praxis Medical Insights 4

The Society of Critical Care Medicine suggests targeting ECMO flow of 3-4 L/min immediately after cannulation, gradually increasing as tolerated, as stated in Critical Care Medicine 8, 5
The American Thoracic Society recommends maintaining arteriovenous oxygen difference between 3-5 cc O₂/100ml of blood as the most reliable parameter for setting ECMO flow goals, according to Critical Care Medicine 8, 5
The European Society of Intensive Care Medicine advises maintaining mean arterial pressure (MAP) >70 mmHg to ensure adequate cerebral and end-organ perfusion while minimizing left ventricular afterload, as per Critical Care Medicine 8, 5

The American Thoracic Society recommends maintaining PaO₂ >70 mmHg to prevent hypoxemia-associated ABI, as stated in Praxis Medical Insights 5
The Society of Critical Care Medicine suggests avoiding severe arterial hyperoxia (PaO₂ >300 mmHg), particularly in VA-ECMO where reperfusion injury risk is high, according to Praxis Medical Insights 5

The Neurocritical Care Society recommends against using tissue plasminogen activator (tPA) for acute ischemic stroke in ECMO patients due to high bleeding risk with systemic anticoagulation and platelet dysfunction, as stated in Critical Care 6, 4
The American Heart Association recommends mechanical thrombectomy for acute large vessel occlusion, according to Critical Care 6, 4

The American Academy of Neurology recommends using a multimodality, multidisciplinary approach combining clinical/neurological examination, electrophysiological tests, and neuroimaging for neurological prognostication, as stated in Critical Care 6, 4
The Neurocritical Care Society suggests that poor neurological outcome is strongly suggested by ≥2 indicators of severe ABI in ECPR patients, including absence of pupillary and corneal reflexes, bilateral absence of N20 cortical waves on SSEP, highly malignant EEG patterns, and extensive diffuse anoxic injury on brain CT/MRI, according to Critical Care 6
