ObjectiveTo describe the landscape of vasopressin uses reported to the American Heart Association National Registry of cardiopulmonary resuscitation (CPR) and test the hypothesis that vasopressin use will be associated with improved return of a sustained circulation (ROSC) following in-hospital pediatric cardiac arrest.DesignMulticentered, national registry of in-hospital CPR.SettingOne hundred seventy-six North American Hospitals reporting to registry from October 1999 to November 2004.PatientsTotally, 1293 consecutive pediatric patients with pulseless cardiac arrest meeting criteria for analysis identified from a registry of all patients resuscitated for cardiac arrest. Inclusion criteria were age <18 years, chest compressions and/or defibrillation, in-hospital location, and documented resuscitation record.InterventionsNone.Measurements And OutcomesPrearrest, event, cardiopulmonary resuscitation, and postresuscitation variables were collected. Primary outcome variable was ROSC >20 minutes. Secondary survival outcomes included 24 hour, discharge and favorable neurologic survival on hospital discharge. Descriptive, univariate, and multivariable analysis to evaluate the association of vasopressin with survival outcomes were performed.ResultsOnly 5% of patients received vasopressin in this review. Vasopressin was most often given in a pediatric hospital (57%) and in and intensive care setting (76.6%). Patients who were given vasopressin had longer arrest duration (median 37 minutes) vs. those who did not (24 minutes) (p = 0.004). In multivariate analysis, vasopressin was associated with worse ROSC but no difference in 24 hours or discharge survival.ConclusionVasopressin was given infrequently in in-hospital cardiac arrest. It was most likely to be given in an intensive care setting, and in a pediatric hospital. Multivariate analysis shows an association with vasopressin use and worse ROSC.
