Analysis on fatal risk factors to in-hospital children with cardiorespiratory arrest

Abstract

Objective To investigate the fatal risk factos to in-hospital children with cardiorespiratory arrest(CRA). Methods Eighty-seven patients admired to PICU of Yantai Yuhuang-ding Hospital who occurred CRA and received cardiopulmonary resuscitation ( CPR ) were reviewed from January 2006 to December 2008. The clinical and CPR data was analyzed to explore fatal risk factors by Pearsonx2 test and multivariate and unconditioned Logistic regression analysis. Results Forty-five of eighty-seven cases did not received return of spontaneous circulation( ROSC), the initial mortality was 51.7%. Age, primary diseases and complications,blood gas analysis, the interval of CRA to CPR (TCRA-CPR), tracheal intubation or not, the dose of adrenaline,the duration of CPR(TCPR) were obviously associated with mortality. Logistic regression analysis revealed that TCRA-CPR and TCPR were independent fatal risk factors. Conclusion Mortality of in-hospital children with CRA was high. Age, primary diseases and complications, blood gas analysis and good quality CPR affect mortality, especially the interval of CRA to CPR and duration of CPR.
