BackgroundWe reviewed the outcomes of patients who underwent cardiopulmonary support (CPS) for either refractory sudden cardiac arrest or failure to wean from cardiopulmonary bypass (CPB).MethodsBetween January 2005 and July 2013, 37 patients with congenital heart disease (CHD) underwent 39 instances of CPS for sudden cardiac arrest as extracorporeal cardiopulmonary resuscitation (E-CPR; group I, n = 19) or for failure to wean from CPB (group II, n = 20). Univariate analyses determined which variables differed among the groups and which had significant association with hospital survival. Binary logistic regression determined the significant associations in a multivariable model.ResultsOverall 30-day and hospital survival were 76.9% (30) and 69.2% (27), respectively. For groups I and II, hospital survival was 68.4% (13) and 70.0% (14), respectively. Variables associated with mortality in the univariate analysis included hours on CPS (P = .045), initial aspartate aminotransferase (AST) level on CPS (P = .007), and bicarbonate 24 hours on CPS (P = .004). Logistic regression showed single-ventricle physiology (P = .05), initial AST level on CPS (P = .03), and lower bicarbonate 24 hours on CPS (P = .026) to be significantly associated with mortality.ConclusionsComparable rates of survival to discharge can be obtained when CPS is initiated for E-CPR or for failure to wean from CPB in resuscitating patients with CHD. Hepatic and renal factors indicative of inadequate early tissue perfusion, single-ventricle physiology, and lower bicarbonate level are factors associated with poor outcome.© The Author(s) 2015.
