Active clinical trials for "Heart Arrest"

The main objective of the trial is to find out if there is correlation between cerebral and skeletal muscle oxygenation values during cardiopulmonary resuscitation and if these values can predict return of spontaneous circulation. The investigators would like to find out which values, first measures, average, maximal, are better predictor of return of spontaneous circulation. All the patients with nontraumatic cardiac arrest in prehospital environment will be enrolled in the study. The measurements will be taken with NIRS device and special electrodes, which will be placed on patient's forehead and thenar eminence od right hand. No ALS procedure will be modified.

Even in patients with successful return of spontaneous circulation (ROSC), outcome after cardiac arrest remains poor. The overall in-hospital survival rate widely varies both worldwide and across communities, from 1 to 4 folds according to circumstances of arrest and post-resuscitation interventions. Several studies have already shown that early interventions performed after ROSC, such as treatment of the cause, targeted temperature management, optimal hemodynamic management and extra-corporeal life support in selected patients, could improve the outcome in post-cardiac arrest patients. However, the decision process regarding the allocation of these resources, in parallel with the management of patients' proxies, remains a complex challenge for physicians facing these situations. Consequently, several prediction models and scores have been developed in order to stratify the risk of unfavorable outcome and to discriminate the best candidates for post-resuscitation interventions. Overall, several scores exist, but external validation are lacking and direct comparisons are needed to assess relative interest of scoring systems. Indeed, establishing the optimal scoring system is crucial, for optimal treatment allocation and appropriate information to relatives.

This is a clinical observation study based on analysis of video-clip data of cardiopulmonary resuscitation (CPR) for out-of hospital cardiac arrest (OHCA) in emergency department. Aim of study is to evaluate effect of the factors relating endotracheal intubation (ETI) on the outcome of OHCA patients.

Study Title: Early recorded P25/30 somatosensory evoked potentials are associated with neurologic prognosis of comatose survivors after out of hospital cardiac arrest. Design: Prospective, observational, non-interventional, study - prospective collection of data and interpretation. Analysis of the data and assessment of prognostic value of the P25/30 in critically ill patients post cardiac arrest. Study Aims: To be the first attempt to validate the prognostic potential of early recording [between 24-36 hours post Return Of Spontaneous Circulation] of P25/30 potentials in comatose survivors who are admitted to a British Intensive care unit after out of hospital cardiac arrest and who are not treated by hypothermic targeted temperature management. [Validation of the prognostication significance of P25/30 Somatosensory Evoked Potentials in predicting neurologic outcome in comatose survivors post out of hospital cardiac arrest]. Outcome Measures: Primary Endpoint: Neurologic outcome assessed by Cerebral Performance Category score at hospital discharge. Secondary endpoints: Mortality at hospital discharge and 28 days [which occurs first], comparison of prognostic benefit of N20 and P25/30 based multimodal prognostic models. Population: Comatose survivors, after out of hospital cardiac arrest, treated in Derriford Hospital ICU, Penrose and Pencarrow wards. Eligibility: Adults [>18 years old], out of hospital cardiac arrest, comatose after Return Of Spontaneous Circulation, admission to intensive care Estimated Duration:36 months

Survival following cardiopulmonary resuscitation (CPR) from out-of-hospital cardiac arrest (OHCA) depends on numerous prehospital and in-hospital variables and interventions. The aim of this study was to develop a score to predict the resuscitation outcome after OHCA at hospital discharge. All patients suffered OHCA between 01.01.2010 and 31.12.2016 with ROSC or ongoing CPR at hospital admission in Emergency Medical Service (EMS) systems with good quality in documentation in the German Resuscitation Registry (GRR) were included. The study population was divided into development dataset (5,775) and validation dataset (1,457) by random. Binary logistic regression analysis was used to derive the score. Hospital discharge with good neurological function (CPC 1-2 or mRS 0-2) was used as dependent variable, and various combination of potential predictor variables were used to create the model.

Measurement of Near-Infrared Spectroscopy (NIRS) during and after out-of-hospital cardiac arrest (OHCA) in the city of Vienna and the tertiary university hospital of the Medical University of Vienna, Austria. NIRS will be evaluated as a tool for resuscitation quality assessment as well as a prognosticator for cardiac arrest outcomes. Already-existing literature will be taken into account, and already-existing cutoffs and prognosticating values will be assessed and - if eligible - validated in a real-life setting.

Persistent microperfusion alterations after return of spontaneous circulation (ROSC) are associated with poor survival. To our knowledge, no human studies evaluating microperfusion during cardiopulmonary resuscitation (CPR) with simple and pre-hospital available tests have been published. Capillary refill time (CRT) and skin-mottling-score (SMS) are parameters for microperfusion and evaluated in septic and cardiogenic shock. In animal studies, microperfusion was impaired during cardiac arrest, although not correlating with systemic blood pressure. The aim of this study is to investigate the correlation between impaired microcirculation (as measured with CRT and SMS) during resuscitation and ROSC resp. neurological outcome. Our clinical impression in daily routine is, that the appearance of a patient undergoing CPR is often linked to the outcome. We hypothesize, that this is due to changes in microperfusion of the skin.

In the Paris (France) Medical Emergency system, in the early phase of Out-of-hospital Cardiac Arrest (OHCA), the treatment of a Ventricular Fibrillation (VF) consists of delivering an External Electric Shock (EES) by a rescuer with the use of an Automated External Defibrillator (AED). This latter realizes a cardiac rhythm analysis every two minutes. This analysis requires that chest compressions (CC) be interrupted for a while. However, CC interruptions are potentially harmful due to the brain, and heart perfusions decrease. On the other hand, the recurrence of VF occurs mostly during the first minute after the shock, whereas the delay between 2 rhythm analysis is 2 minutes. The consequence is excessive time spent in VF, which is deleterious in terms of coronary and cerebral perfusion. The investigator implements a new AED algorithm whose operating principle is as follows. One minute after an EES administration, the AED realizes a cardiac rhythm analysis during which the rescuers do not need to interrupt the chest compressions (CC): this is called the rhythm analysis " in presence of CC" The detection of a VF " in presence of CC " needs to be confirmed, " in absence of CC " The CC's are therefore interrupted for new rhythm analysis. Once the presence of VF is approved, the AED proposes a shock to be administred The aim of the study Study Design: This is a prospective observational study. The eligibility criteria are as follows: Patients in Out-Of-Hospital Cardiac Arrest. Basic Life support care with an AED. The primary endpoint is the " chest-compression fraction (CCF) " that represents the CPR-time performance during the ten first minutes of BLS care ( or < 10 min in case of Return Of Spontaneus Circulation (ROSC))

The AutoPulse Resuscitation System Model 100 (ZOLL Medical Corporation, Chelmsford, MA, US) ZOLL has been used as a standard treatment for a number of subjects in this trial and granted CE marking for Europe in November of 2003. The AutoPulse device is an automated, portable, battery-powered, load-band-distributing (LDB), chest compression device, which provides chest compressions as an adjunct to performing manual cardiopulmonary resuscitation (CPR). Use of the device is intended to provide consistent chest compressions without interruption to a victim of out-of-hospital cardiac arrest (OOHCA), to reduce the impact of rescuer fatigue due to application of manual CPR, and to enable rescuers to address additional patient needs. In the present study investigators will compare electronic data generated during cardiopulmonary resuscitation stored in the different multimonitores between LDB and manual chest compressions.

This study is a sub-study to the large pragmatic Target Temperature Management 2 Trial (TTM2-trial, ClinicalTrials.gov Identifier: NCT02908308), assessing effectiveness of controlled hypothermia after out-of-hospital cardiac arrest (OHCA). This study is designed to provide detailed information on cognition after OHCA and its relationship to associated factors as emotional function, fatigue, and sleep. A secondary aim is to utilize this information to validate a neurocognitive screening battery used 6 months after OHCA in the TTM2-trial. Approximately 7 and 24 months after OHCA, survivors at selected TTM2 study sites will perform a standardized neuropsychological assessment including performance-based tests of cognition and questionnaires of behavioral and emotional function, fatigue, and insomnia. At 1:1 ratio, a control group of myocardial infarction (MI) patients but no occurrence of cardiac arrest will be recruited and perform the same test battery. Group differences at 7 and 24 months will be analyzed per cognitive domain (verbal, visual/constructive, short-term working memory, episodic memory, processing speed, executive functions). Results of the OHCA survivors on the TTM2 neurocognitive screening battery will be compared with neuropsychological test results at 7 months time.
