Filter by:Elevation of the head and thorax, also known as Head-up cardiopulmonary resuscitation (HUP CPR), has been studied extensively in pigs in ventricular fibrillation (VF). HUP combined with active compression decompression and impedance threshold device (ACD+ITD) CPR improves vital organ perfusion and results in a doubling of cerebral perfusion when compared with the same method of CPR in the flat or horizontal plane. HUP CPR enhances the drainage of venous blood from the brain, lowers central venous pressures, reduces intracranial pressures during the decompression phase of CPR, redistributes blood flow through the lungs during CPR, and may reduce brain edema. These mechanisms collectively contribute to improved blood flow and less injury to the brain during CPR. These benefits are due in large part to the effects of gravity on the physiology of HUP CPR. Importantly, HUP CPR is dependent upon a means of generating enough forward flow to adequately pump blood "uphill" to the brain. In this proposed pilot study, CPR will be performed manually before the patient is placed on a controlled mechanical elevation device (Elegard, Minnesota Resuscitation Solutions LLC, USA). An ITD-16 (ResQPOD-16, Zoll, USA) will be placed on the patient's airway before the head is elevated. Automated CPR will be initiated as soon as feasible using a new automated CPR mechanical compression device that provides full active compression-decompression CPR (LUCAS-AD, Stryker, USA). The proposed feasibility clinical study will be the first ever to test the fully integrated system of ACD+ITD HUP CPR.
Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of mortality in the industrialized world. Bystander CPR before arrival of the Emergency Medical Service (EMS) is associated with an increased chance of survival. During the last decade, the best form of bystander CPR has been debated. Chest Compression Only CPR (CO-CPR) has been advocated as a preferable method in situations where the bystander has no previous knowledge in CPR, both because its believed to be equally efficient but also a simplified form of CPR that could lead to a higher incidence of bystander-CPR. In an initiative to increase CPR rates the American Heart Association has launched public campaigns such as the "hands-only CPR" promoting CO-CPR as an option to S-CPR for adult non-asphyxic cardiac arrest. In the 2015 updates of the European resuscitation council guidelines it states that the confidence in the equivalence between the two methods is not sufficient to change current practice. Whether CO-CPR leads to a survival rate no worse than, equally effective, or even superior to standard CPR in situations where the bystander has previous CPR training however remains unclear. This clinical question remains unanswered while millions of people are trained in CPR worldwide each year. The overall purpose with this research project is to investigate whether instructions to perform a simplified form of CPR consisting of compressions only (CO-CPR) to bystanders with prior CPR-training is non-inferior, or better than, standard CPR (S- CPR) in witnessed Out-of-Hospital Cardiac Arrest (OHCA).
The study performed to demonstrate a reasonable assurance of safety and effectiveness of the Heart Guardian HR-501 when used in an out-of-hospital environment.
This study aims to evaluate the electrophysiological properties of the heart conduction system in patients with unexplained polymorphic ventricular tachycardia (VT) and/or ventricular fibrillation (VF), in patients with specific genetic mutations regarding sudden cardiac death or sudden cardiac arrest, in their family members and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Also a National Dutch registry for patients with unexplained polymorphic VT and/or VF and their family members will be created. By combining the data from the registry and the results of ECGI, The investigators hope to identity risk markers for patients at higher risk for apparently idiopathic ventricular fibrillation, and use these for an adapted flow chart for the 'general'population of patients at risk for unexplained polymorphic VT and/or VF. The investigators aim to be able to identify patients before the first arrhythmic event, and aim for better treatment strategies in the future.
BASIC is a perspective, multicentre and large-scale registry focusing on of patients suffering a cardiac arrest in China. The aims of the study are to establish the monitoring sites covering out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) in urban and rural areas in 7 regions (East China, North China, South China, Central China, Northeast China, Southwest China and Northwest China) around China, to collect data from cardiac arrest patients, and to describe basic characteristics, treatments, outcomes, incidences and risk factors of OHCA and IHCA in China.
The study investigators will recruit paramedics in many Emergency Medical Services (EMS) in Switzerland to prepare direct intravenous (IV) emergency drugs during a standardized simulation-based pediatric out-of-hospital cardiac arrest scenario. According to randomization, each paramedic will be asked to prepare sequentially 4 IV emergency drugs (epinephrine, midazolam, dextrose 10%, sodium bicarbonate 4.2%) following either their current conventional methods or by the aim of a mobile device app. This app is designed to support drug preparation at pediatric dosages. In a previous multicenter randomized trial with nurses, the investigators reported the ability of this app to significantly reduce in-hospital continuous infusion medication error rates and drug preparation time compared to conventional preparation methods during simulation-based resuscitations. In this trial, the aim was to assess this app during pediatric out-of-hospital cardiopulmonary resuscitation with paramedics.
The European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM) joint guidelines for post-resuscitation care recommend a multimodal approach to prognostication of neurological outcome. However, head computed tomography (CT) which is commonly used for predicting long-term neurological outcome after cardiac arrest has not yet been examined prospectively in a clinical trial. The primary purpose of the TTM-2 CT-substudy is to prospectively investigate and compare various methods of diagnosing generalized oedema on CT after cardiac arrest and it´s ability to predict long-term neurological outcome.
Sudden cardiac death is one of the main causes of morbidity and mortality worldwide. Cardiac arrest requires prompt intervention by cardiopulmonary resuscitation (CPR). The resuscitation guidelines are the current recommendations for CPR and are revised by expert panels such as the "European Resuscitation Council (ERC)". Up to now, a parameter for assessing the quality of CPR is missing and further monitoring methods are urgently needed. Near-infrared spectroscopy (NIRS) is a portable method for measuring regional oxygen levels in the brain. Recent clinical trials suggest that cerebral oxygenation measured by NIRS may correlate with survival and outcome after cardiac arrest. The investigators propose that NIRS technology may not only be suitable to determine or predict the outcome of the patients, but could also be a useful tool to guide the CPR providers to optimize the CPR techniques and guide the individual treatments/interventions. The present study was therefore designed to determine if NIRS guided CPR with the aim to optimize NIRS values is superior compared to the current standard practice according to published CPR guidelines (return of spontaneous circulation [ROSC] rate, short and long-term cerebral performance).
This study will test the feasibility and acceptability of deploying a decision aid for surrogate decision makers of comatose survivors of cardiac arrest early during hospitalization. This decision aid is to inform, educate and support decision makers charged with determining goals of care during post-cardiac arrest treatment.
The purpose of this study is to determine whether the blood transcriptome of patients resuscitated after out-of-hospital could be an early predictor of the neurological outcome.
