Filter by:The objective of this study will be to assess the frequency of return of spontaneous circulation (ROSC), survival to admission, survival to discharge from the hospital, and neurologic function at time of discharge from the hospital among patients experiencing out of hospital cardiac arrest randomized to receive either intra-arrest induction of therapeutic hypothermia (IATH) or post-arrest therapeutic hypothermia (TH).
Promising result of intra-arrest cooling on neurological intact survival in cardiac arrest patients has recently been published in the PRINCE-study in Circulation 2010. The main purpose of this study is to determine whether prehospital intra-nasal cooling initiated during resuscitation, in addition to systemic cooling at hospital, increases neurological intact survival measured as cerebral performance category score (CPC-score)at 90 days in witnessed cardiac arrests outside hospital.
STUDY OBJECTIVES The overall goal of this study is to compare bystander fatigue and CPR quality after 5 minutes of continuous chest compressions versus the 2005 30:2 chest compression to ventilation Resuscitation Guidelines, in a population aged 55 or greater. More specifically, the investigators will compare each CPR ratio with regard to: 1. The achieved frequency and depth of chest compressions, and 2. Participant rating of their perceived level of exertion. STUDY HYPOTHESIS In a population aged 55 or greater, the new CPR recommendations will lead to: 1. less frequent and shallower chest compressions over the 5-minute study period; and 2. higher rating of perceived level of exertion when compared to the 2005 30:2 CPR ratio.
The primary aim of the trial is to compare survival to hospital discharge after continuous chest compressions (CCC) versus standard American Heart Association (AHA) recommended cardiopulmonary resuscitation (CPR) with interrupted chest compressions (ICC) in patients with out-of-hospital cardiac arrest (OOHCA). The primary null hypothesis will be that the rate of survival to hospital discharge is not affected by use of continuous compressions with passive or positive pressure ventilation (intervention group) versus CPR with compressions interrupted for ventilation at a ratio of 30:2 (control group).
During thoracic aortic surgery, hypothermic cardiac arrest causes aortic ischemia and reperfusion (IR) periods, respectively. Aortic ischemia results in an ischemic insult to the lower extremities and successive reperfusion results in injury to remote organs, including kidneys. So, there has been considerable interest in the development of therapeutic strategies aimed at attenuating IR injury. One such group of agents that are attracting interest due to their potential protective effects on vascular endothelium is the erythropoietin. However, the effect of erythropoietin on renal injury induced by aortic IR in humane has not been fully clarified. Therefore, the purpose of this study is to determine whether the prophylactic administration of erythropoietin reduce the incidence of acute kidney injury (AKI) in patients undergoing thoracic aorta surgery with hypothermic cardiac arrest. The investigators administrate the erythropoietin single bolus (500 IU/kg intravenously) 30 min before the commencement of ischemia. The differences between the control and study groups are observed by clinical indicators such as serum creatinine, TNF-α, NGAL.
The debate over the administration of sodium bicarbonate in cardiac arrest has been going on for several decades, swinging like a pendulum from "first-line drug" to "not indicated" to the recent guidelines advocating "a small bolus under special conditions (metabolic acidosis, intoxication, long-term resuscitation)". A targeted, blood-gas controlled application under optimised ventilation conditions has not yet been evaluated prehospitally. Our preliminary studies have shown that an arterial puncture/line as well as measurement of blood gases is feasible in preclinical conditions. This multicentre trial including 5 centres and 10 physician-staffed emergency systems is designed to compare, in a prospective randomised controlled study, the effect of a calculated dosage of sodium bicarbonate based on the patient´s base deficit and weight, on ROSC (= return of spontaneous circulation) and on the secondary survival of cardiac arrest patients. The null hypothesis is that there is no or negative impact on survival.
The purpose of this study is based on method Utstein, registering all recommended items of that model, in addition to adding more information, characterizing this way using a template Utstein modified for the epidemiology of PCR-hospital in Brazil. Objectives: establish a registry of patients suffering from respiratory (PCR)-hospital to assess demographic and clinical variables such as morbidity, mortality and standard practice in cardiopulmonary resuscitation (CPR). In addition, assess independent predictors associated with survival in several times and survival curves.
The purpose of the study is to evaluate the safety and efficacy of wearable defibrillator use in patients with left ventricular dysfunction or advanced heart failure symptoms, who have a high-risk for sudden cardiac death but are either not eligible for an implantable defibrillator under current guidelines or are not able to receive the device due to their condition.
More than 300,000 Americans experience out-of-hospital cardiac arrest annually, with overall survival rates averaging less than 5%. Low survival rates persist, in part, because manual chest compressions and ventilation, termed standard cardiopulmonary resuscitation (S-CPR), is an inherently inefficient process, providing less than 25% of normal blood flow to the heart and the brain. Hemodynamics are often compromised further by poor S-CPR techniques, especially inadequate chest compression and incomplete chest recoil. Active Compression Decompression CPR (ACD-CPR) is performed with a hand-held device that is attached to the patient's chest, and also includes a handle containing a metronome and force gauge to guide proper compression rate, depth and complete chest wall recoil. The impedance threshold device (ITD) is designed for rapid connection to an airway adjunct (e.g. facemask or endotracheal tube) and allows for positive pressure ventilation, while also impeding passive inspiratory gas exchange during chest wall decompression. Prior studies have shown that the combination of ACD-CPR + ITD enhances refilling of the heart after each compression by augmenting negative intrathoracic pressure during the decompression phase of CPR, resulting in improved cardiac and cerebral perfusion. The intrathoracic pressure regulator (ITPR) is a next generation inspiratory impedance therapy. The ITPR uses a regulated external vacuum source to lower the negative intrathoracic pressure and is therefore less dependent on the quality of CPR (e.g., completeness of chest wall recoil). The ITPR generates a pre-set continuous and controlled expiratory phase negative intrathoracic pressure that is interrupted only when positive pressure ventilation is needed to maintain oxygenation and provide gas exchange. The purpose of the study is to compare the early safety and hemodynamic effects of S-CPR, ACD- CPR + ITD, and S-CPR + ITPR in patients with out-of-hospital cardiac arrest.
Specific Aim #1: To determine if levels of CoQ10 are low post-cardiac arrest (CA). We will perform a prospective trial with the primary endpoint of describing the prevalence of low serum CoQ10 levels. Specific Aim #2: To determine if CoQ10 levels in post-CA patients can be increased with the administration of exogenous CoQ10.. We will perform a randomized control trial (RCT) of post-CA patients with the secondary endpoint of comparing CoQ10 levels among those randomized to CoQ10 supplementation vs placebo.
