Filter by:The investigators hypothesized that, following cardiac arrest in pediatric patients, hypothermia therapy will improve the proportion of patients with a good functional outcome compared to a normothermic control group.
The simultaneous activation of adrenergic and vasopressin receptors, in conjunction with a potential steroid-mediated enhancement of the vascular reactivity to epinephrine may have beneficial effects in patients with cardiac arrest. This hypothesis is supported by the single-center results of NCT 00411879. The investigators intend to either refute or provide definitive evidence supporting this hypothesis (and its generalizability) by conducting the present multicenter, randomized, controlled clinical trial of in hospital cardiac arrest.
The purpose of this study is to test the possible neuroprotective effect of early high dose erythropoietin alpha after out of hospital cardiac arrest (OHCA).
Background: One of the 2010 Impact Goals of the Emergency Cardiac Care (ECC) Committee of the American Heart Association is to double survival from cardiac arrest. Currently, approximately 60% of adults and 50% of paediatric patients that regain spontaneous circulation following cardiac arrest die before leaving the hospital. A key piece of the "chain of survival" is this fifth link; the care of patients post-arrest. Although there are several modalities recommended for post arrest care, therapeutic hypothermia is the only in-hospital therapy that has been demonstrated in randomized clinical trials to improve patient outcome after cardiac arrest. Despite the strong evidence for its efficacy and the apparent simplicity of this intervention, recent surveys show that hypothermia is delivered inconsistently, incompletely, and with undue delay in hospitals receiving resuscitated patients; only 26% of physicians and 26% of hospitals regularly institute a hypothermia protocol. Primary Objective: To design and apply a knowledge translation program for the 2005 AHA guideline on hypothermia post cardiac arrest and enable effective implementation of hypothermia in 100% of eligible OHCA patients. The integration of two robust data collection systems, which include both pre-hospital and in-hospital indicators, will give complete process of care and clinical outcome information for all cardiac arrest patients. Primary Endpoint: the proportion of eligible out of hospital cardiac arrest patients cooled to 32-34°C within 6 hours of ED arrival. Study Design: This project will be implemented through an established research collaborative of 43 hospitals in southern Ontario currently participating in the Toronto site of the Resuscitation Outcomes Consortium. A stepped wedge study design will be employed, whereby the intervention will be rolled-out sequentially to the participating hospitals over a number of time periods as sites reach pre-defined benchmarks. The multifaceted KT strategy will include 1) local multidisciplinary champions in ED, ICU, and Cardiology 2) A simple protocol for application of hypothermia, tailored to local needs and policy; 3) Identification of perceived and actual barriers to knowledge use; 4) Development of an implementation tool kit and 5) Providing timely feedback on benchmarks for hypothermia and outcomes
Therapeutic hypothermia has been shown to improve survival and neurologic outcome in patients resuscitated after ventricular fibrillation arrest. Few studies have examined whether therapeutic hypothermia is effective outside the research setting, or with other presenting rhythms. Our institution, a large community teaching hospital, instituted a therapeutic hypothermia protocol in November 2006 for all resuscitated cardiac arrest patients. The investigators seek to determine the mortality rate of our protocol and compare our complication rates with those of previously published studies.
The major goal of this project is to determine whether the use of physiologic doses of corticosteroids will decrease time to shock reversal, alters the inflammatory cascade, and alters microcirculatory flow in post-cardiac arrest patients.
The goal of this study is to conduct a survey to better understand the factors associated with undertaking cardiopulmonary resuscitation (CPR) training and performing CPR in an emergency situation.
The overall goal of this study is to better understand the factors leading to successful dispatch-assisted CPR instructions and to ultimately save the lives of more cardiac arrest patients. Specific objectives are to: 1) Determine the ability of 9-1-1 dispatchers to make the diagnosis of cardiac arrest over the phone; 2) Quantify the frequency and impact of perceived agonal breathing on cardiac arrest diagnosis; 3) Measure the frequency with which dispatch-assisted CPR instructions can be successfully completed in out-of-hospital cardiac arrest cases; and 4) Measure the impact of dispatch-assisted CPR instructions on bystander CPR and survival rates for out-of-hospital cardiac arrest.
1. Pre-shock cardiopulmonary resuscitation might benefit the survival of out-of-hospital cardiac patients with ventricular fibrillation / ventricular tachycardia in a post-hoc analysis of a prehospital trial conducted in Europe (L.Wik,2002). However, it's effectiveness in the Asian countries, where most firstly recorded rhythm in out-of-hospital cardiac arrests patients were asystole/pulseless electric activity rather than ventricular fibrillation / ventricular tachycardia, were not explored yet. 2. This trial was designed to exam if pre-shock cardiopulmonary resuscitation by emergency medical technicians improves the outcome of all out-of-hospital cardiac arrest patients in an Asian metropolitan city.
New single use laryngoscope metal blades are available for intubation. This type of blade is safer than the reusable ones concerning the interhuman cross infection risk. No clinical studies have compared the two types of blades in the emergency context. The primary aim of this study is to demonstrate that single use blades are as efficient as the reusable ones concerning intubation conditions.
