Risk Factors of Fux et al for Mortality in a Patient Undergoing Venoarterial Extracorporeal Membrane Oxygenation (ECMO) for Postcardiotomy Shock

Patient selection: postcardiotomy shock

Outcome: 90 days mortality

Percent having 90-day mortality: 57%

Risk factors from multivariate logistic regression analysis:

(1) pre-ECMO arterial lactate in mmol/L (OR 1.22 per mmol/L)

(2) ischemic heart disease (OR 7.9)

where:

• The average arterial lactate for survivors was 4.0 vs 8.0 for nonsurvivors.

• Only 13% of patients with a lactate >= 10 survived.

• Only 23% of patients with ischemic heart disease survivved.
