(how?)

Patient Population (Who?)
Defining the Condition:
• Cardiac Arrest Definitions
• Patient Diagnostic Groups
• Cardiac Arrest Rates
Alfred Hospital - Melbourne
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
hypothermia
i.e. the CA has contributed to the
patient neurological outcome

Patient Population (Who?)
Defining the Condition:
• Cardiac Arrest Definitions
• Patient Diagnostic Groups
• Cardiac Arrest Rates
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”
no ROSC ROSC+

8. The Alfred Intensive Care Unit, Melbourne, Australia
Patient Population (Who?)
Defining the Condition:
• Cardiac Arrest Definitions
• Patient Diagnostic Groups
• Cardiac Arrest Rates
ELSO: Ann Thor Surg 2009
“The registry defines E-CPR as the following:
“extracorporeal life support (ECLS) used
as 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].
no ROSC ROSC+
9. The Alfred Intensive Care Unit, Melbourne, Australia
Patient Population (Who?)
Defining the Condition:
• Cardiac Arrest Definitions
• Patient Diagnostic Groups
• Cardiac Arrest Rates
Korea
“The ECPR was defined as use of venoarterial
ECMO intended to treat cardiac arrest”
“received veno-arterial ECMO upon the
recurrence of CA within 20 min after the
return of spontaneous circulation
(ROSC) or due to no signs of ROSC
after >10 min of CPR following AMI-
induced CA (Figure 1). All patients
underwent ECMO during ongoing
continuous chest compressions”
10. The Alfred Intensive Care Unit, Melbourne, Australia
Patient Population (Who?)
Defining the Condition:
• Cardiac Arrest Definitions
• Patient Diagnostic Groups
• Cardiac Arrest Rates
Korea
“In previous studies, the definition of ECPR included both
successful veno-arterial ECMO implantation and pump-on
during cardiac massage [10,11]. However, various
unexpected situations occurred in ongoing ECPR scenes.
Actually, when a return of spontaneous circulation (ROSC)
occurs during ECMO cannulation, the practitioner does not
remove the already inserted cannula and does not stop the
process of ECMO pump-on. We included such cases in our
ECPR definition as intention-to-treat. Accordingly, ECPR
was defined as an intention-to-treat with hemodynamic
ECMO support during cardiac massage regardless of
interim ROSC [11]”
no ROSC ROSC+
11. The Alfred Intensive Care Unit, Melbourne, Australia
Patient Population (Who?)
Defining the Condition:
• Cardiac Arrest Definitions
• Patient Diagnostic Groups
• Cardiac Arrest Rates
The Problem
The majority of patients that may benefit
from emergency ECMO following cardiac
arrest have some return of circulation
Also, it is common for patients receiving
ECMO for cardiac failure to have had a
preceding CA
Universal definitions of ROSC are lacking
Cardiac arrest occurs in many different
settings (in hospital and out of hospital)
no ROSC ROSC+

Future Models are essential
1.  Age
2.  First monitored rhythm
3.  Time to ECMO
4.  Biomarkers (early lactate)
5.  No/minimal physiological data

Conclusions
E-CPR has strong physiological and evidence base to
support its use and ongoing development
Large 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……
