Evidence suggests improved outcomes in selected patients with cardiac arrest, but limited data, complications, and resource demands may restrict broader use.
To evaluate the benefits and ethical challenges of extracorporeal cardiopulmonary resuscitation (eCPR) in patients with cardiac arrest.
Key Findings:
eCPR is associated with improved survival to hospital discharge and at 30 and 180 days compared to conventional CPR.
A meta-analysis of 14,048 patients showed improved short-term neurologic outcomes with eCPR.
Complications from eCPR are common, including bleeding (8%-70%), infections (8%-22%), and limb ischemia (3%-15%).
Neurologic injury is a major determinant of outcomes, with about 10% of patients meeting criteria for death by neurologic criteria.
eCPR may exacerbate disparities in care due to resource limitations.
Interpretation:
While eCPR shows promise for improving survival and neurologic outcomes, its application raises significant ethical and resource allocation concerns.
Limitations:
Heterogeneous evidence base primarily from specialized centers limits generalizability.
Variability in patient selection and lack of standardized eligibility criteria.
Most studies focused on survival rather than long-term neurologic function or quality of life.
Conclusion:
Responsible, patient-centered application of eCPR, along with ongoing ethical reflection and scientific evaluation, is essential for its integration into future resuscitation strategies.
In a multicenter registry study, genetic diagnoses were associated with substantially lower cognitive, language, and motor scores; while birth weight, surgical timing, hospitalization burden, and caregiver education were also associated with outcomes.
