Checchia P, Moynihan JA, Brown L.. "Cardiac Troponin I as a Predictor of Mortality for Pediatric Submersion Injuries Requiring Out of Hospital Cardiopulmonary Resuscitation." Pediatric Emergency Care 22.4 (): 222-225. (*)
Background: It is difficult to predict ultimate survivors to hospital discharge in children who are successfully resuscitated after a cardiorespiratory arrest associated with a submersion injury. Serum measurements of organ injury or dysfunction may serve as a surrogate marker of the degree of hypoxic injury. We designed a prospective study whose purpose was to assess the predictive value for outcome of serum cardiac troponin I measurements after submersion injury and cardiorespiratory arrest.
Methods: This is a prospective, observational study of children admitted to a postintensive care unit after experiencing an out-of-hospital cardiorespiratory arrest associated with a submersion event. Cardiac troponin I measurements were examined upon admission to the postoperative intensive care unit after successful emergency department resuscitation.
Results: Nine patients were admitted, and 2 patients (22%) survived to hospital discharge. The area under the receiver operating characteristic curve is 0.786 (95% confidence interval, 0.481-1.0). This suggests that cardiac troponin I has a moderate degree of discriminatory power in selecting children who did not survive to hospital discharge.
