ECMO commenced within 30 minutes of a cardiac arrest which has been associated with c-CPR for greater than 10 minutes or has rendered

the patient unconscious

Based on the CA definition for therapeutic

hypothermiai.e. the CA has contributed to the

patient neurological outcome

Taipei, Taiwan JACC 2003

“Briefly, patients were recruited into the ECPR group only if they: 1) were in cardiac arrest that necessitated external or open-

chest cardiac massage and a large amount of epinephrine (5 mg) during CPR; 2) could not be returned to spontaneous circulation within 10 to 20 min; and 3) subsequently

received ECMO in the hospital”

“The registry defines E-CPR as the following: “extracorporeal life support (ECLS) usedas part of initial resuscitation from cardiac arrest. Patients who are hemodynamically

unstable and placed on ECLS without cardiac arrest are not considered E-CPR” [1].

Conclusions

E-CPR has strong physiological and evidence base to support its use and ongoing developmentLarge database with accurate data to build risk prediction models to assess performance

•allow better case selection•allow comparison between services•allow comparison between different treatments

Only one thing better than successfully treating a cardiac arrest case with ECMO……
