Management of Patients with a History of ECCO2R

Understanding ECCO2R and Its Applications

ECCO2R is a specialized extracorporeal technique that uses lower blood flow rates to provide partial CO2 clearance while offering minimal oxygenation support, primarily used to avoid unacceptable hypercapnia, acidosis, and/or injurious ventilator settings in patients with respiratory failure 1, 3
ECCO2R specifically focuses on CO2 elimination, unlike venovenous ECMO which targets both oxygenation and CO2 removal 1, 3

Monitor arterial blood gases every 4-6 hours to assess for rebound hypercapnia and respiratory acidosis in the immediate post-ECCO2R period 2, 4
Maintain continuous monitoring of arterial blood pressure and respiratory parameters, with special attention to respiratory rate and work of breathing 1
Perform daily echocardiography to assess cardiac function, especially right ventricular function which may have been affected during ECCO2R therapy 1
Track fluid balance meticulously, as positive fluid balance has been identified as an independent predictor of outcomes in patients who received extracorporeal support 1

Target oxygen saturation of 88-92% in patients with risk factors for hypercapnic respiratory failure to avoid worsening hypercapnia 4
Monitor for signs of respiratory muscle fatigue which may indicate need for ventilatory support 4

Vascular complications: Monitor insertion sites for hematoma, pseudoaneurysm, or arteriovenous fistula formation 1
Hemolysis: Check for signs of hemolysis which may have occurred during ECCO2R therapy 1
Infection: Assess for signs of catheter-related bloodstream infections 1

Schedule pulmonary function tests at 1, 3, and 6 months post-ECCO2R to assess recovery of respiratory function 2
Evaluate for persistent respiratory symptoms that may indicate incomplete recovery or development of chronic respiratory failure 2
Consider cardiac evaluation if there were signs of right ventricular dysfunction during ECCO2R therapy 1

Consider gradual weaning of ventilatory support with close monitoring of work of breathing and gas exchange in ARDS patients 1
Ensure appropriate home oxygen therapy if indicated for COPD patients 4
Consider early intervention with non-invasive ventilation for signs of respiratory deterioration in COPD patients 2

Immediate re-evaluation is needed if pH drops below 7.25 with rising PaCO2 2, 4
Consider non-invasive ventilation if respiratory rate exceeds 25-30 breaths/minute with signs of increased work of breathing 4

Management of post-ECCO2R patients should ideally occur at centers with experience in extracorporeal support techniques 3
Multidisciplinary teams including pulmonologists, intensivists, and respiratory therapists should be involved in the follow-up care 1, 3
