Kaplan\u2010Meier and Cox proportional hazards model analyses were used to estimate the frequency and evaluate risk factors that might predict JET occurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The patients ranged in age from 1\u00a0day to 36.6 years; half were less than 4.8 months at the time of OHS. JET occurred in 115 of 750 (15.3%) OHS. JET was bimodally distributed by age with a peak incidence between 1\u20132 weeks and 1\u20133 years. JET occurred more commonly: (1) in specific types of OHS (single ventricle [19.5%] and cono\u2010truncal defects [19.3%]) (P\u00a0= 0.03); (2) with increased total surgical time (P\u00a0= 0.001), aortic cross\u2010clamp time (P\u00a0&lt; 0.001), cardiopulmonary bypass time (P\u00a0&lt; 0.001); and (3) followed use of inotropic agents (dopamine or milrinone, P\u00a0&lt; 0.001). JET lengthened intensive care stay by 3\u00a0days (P\u00a0= 0.0001) and increased mortality (+JET [9.6%] vs \u2013JET [4.6%], P\u00a0= 0.03). In a multiple variable Cox regression model, total surgical time and PO use of milrinone were the best predictors for JET risk. PO administration of nitroprusside decreased risk of JET.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>JET occurred more commonly following OHS associated with prolonged surgical times and PO use of inotropic medications.
