title: Cardiac arrest and resuscitation in the pediatric intensive care unit: a prospective multicenter multinational study.
abstract: OBJECTIVE
  The aim of the study was to analyze the mortality and neurological outcome factors of in-pediatric intensive care unit (in-PICU) cardiac arrest (CA) in a multicenter international study.
  
  
  METHODS
  It was a prospective observational multicenter study in Latin-American countries, Spain, Portugal, and Italy. A total of 250 children aged from 1 month to 18 years who suffered in-PICU CA were studied. Countries and patient-related variables, arrest life, support-related variables, procedures, and clinical and neurological status at hospital discharge according to the Pediatric Cerebral Performance Category (PCPC) scale were registered. The primary endpoint was survival at hospital discharge and neurological outcome at the same time was the secondary endpoint. Univariate and multivariate logistic regression analyses were performed.
  
  
  RESULTS
  Return of spontaneous circulation maintained longer than 20 min was achieved in 172 patients (69.1%) and 101 (40.4%) survived to hospital discharge. In the univariate analysis, oncohematologic diseases, inotropic infusion at the time of CA, sepsis and neurologic causes of CA, primary cardiac arrest, need of adrenaline, bicarbonate or volume expansion during resuscitation, and long duration of resuscitation were related with mortality. In the multivariate logistic regression analysis, factors related to mortality were hemato-oncologic illness and previous treatment with vasoactive drugs at the time of CA event, neurological etiology of CA, and cardiopulmonary resuscitation (CPR) duration for more than 10 min. One year after CA, neurological status was assessed in 65 patients; among them, 81.5% had mild disabilities or none.
  
  
  CONCLUSIONS
  Survival with good neurological outcome of CA in the PICU is improving. The most important prognostic indicator is the duration of resuscitation.
