Filter by:In Kuopio University Hospital Department of Clinical Neurophysiology there have been designed a fast EEG electrode, that is suitable for acute emergency use. This study will address the clinical use of acute EEG with this fast EEG electrode in in- hospital patients who have been resuscitated due to cardiac arest. After resuscitation patients will be treated in ICU and EEG will be recorded for 24 hours.
Approximately 50,000 patients are victims of out of hospital cardiac arrest every year in France. Despite cardiopulmonary resuscitation (CPR) and many studies on the topic resuscitation survival after cardiac arrest remains low (1-8%) and has not changed significantly over the past five decades.It has recently been shown that the combination of different non-invasive therapies, cardiopulmonary resuscitation with mechanical CPR with automated compression / decompression and an impedance threshold device, can increase the rate of return of spontaneous circulation and short and long term survival after cardiac arrest.We propose to study a new cardiopulmonary resuscitation called SNPeCPR (Sodium nitroprusside enhanced cardiopulmonary resuscitation), which includes two components:a) a mechanical component: cardiopulmonary resuscitation with automated mechanical external chest compression and an impedance threshold deviceb) a pharmacological component: sodium nitroprusside, an effective arterial vasodilator that decrease vascular resistance, and improve flow in vital organs.Our hypothesis is that SNPeCPR should improve the return of spontaneous circulation rate during cardiac arrest.
Therapeutic hypothermia improves the neurologically-intact survival rates in those patients resuscitated out-of-hospital from ventricular fibrillation. Cooling as early as possible might be beneficial to those victims. Diffusion Tensor Imaging and diffusion-weighted magnetic resonance imaging have recently shown to be able to identify early ischemia-related changes within the brain three days after cardiac arrest, among sudden cardiac arrest patients cooled in hospital. The physical changes seen within the brain may be able to distinguish survivors at very early phase. This study aims to assess early ischemia-related changes of the brain seen in MRI approximately three days after cardiac arrest. The hypotheses is that MRI will differ in the groups of patients treated with early intra-arrest cooling with the RhinoChill device and in hospital hypothermia in 36 Celsius, in the group of patients treated with normal in hospital hypothermia in 36 Celsius only, in the group of patients treated with normal in hospital hypothermia in 33 Celsius only (The historical Xenon study patients). The primary endpoint is the presence and pattern of white matter and gray matter degeneration and volumetric changes of the gray matter, white matter, and cerebro-spinal fluid spaces in MRI, and secondary endpoints are total survival at 90 days, and time to reach a target temperature (≤36/33 Celsius).
The main objective of this trial is to compare the effectiveness of a newer supraglottic airway method (the i-Gel), compared to current airway management practice in out-of-hospital cardiac arrests treated by Norwegian ambulance services.
Cardiac arrest is the most common cause of death in the United States and as many as 590,000 Americans suffering a cardiac arrest each year. Despite advances in care, as many as 50 to 89% of patients who are resuscitated after a cardiac arrest die in the hospital. Brain injury is the most common cause of death and disability after cardiac arrest. The investigators use advanced brain monitoring in patients who are at high risk of death after cardiac arrest, with the goal of preventing ongoing brain injury. The most common problem the investigators have observed is low oxygen levels in the brain, which is often very difficult to treat. In this study, the investigators plan to use two additional brain monitors in the care of these high risk patients: a monitor for seizures and a monitor of the amount of blood flow in the brain. The investigators will use these to detect and treat potential causes of low brain oxygen levels. The main hypotheses are that electrical events in the brain such as seizures and "spreading depolarizations" will occur during times of low brain tissue oxygen level, and that treating these events and low blood flow will reduce the rate of low brain oxygen levels.
During CPR bag-valve mask ventilation is difficult for basically skilled rescuers. Ventilation may be inefficient or with too high pressures result in stomach inflation and aspiration. Studies suggest that with a supraglottic airway device, such as the laryngeal tube, a basically skilled rescuer may ventilate more efficient and also safer. No prehospital study has been conducted comparing laryngeal tube and bag-valve mask ventilation during CPR. Thus, this study intends to compare ventilation with laryngeal tube and bag-valve mask performed by paramedics during CPR.
The purpose of this study is to determine if induced therapeutic hypothermia (ITH) in the pre-hospital setting of a four county emergency medical system (EMS) that serves both urban and rural communities improves meaningful survival from medical cardiac arrest.
The purpose of the study is to analyze the different patient profiles implanted with an Implantable Cardiac Defibrillator (ICD) in Spain (guidelines adoption) and the patient prognosis as a function of clinical profile, implant indication, arrhythmias incidence, treatments or device programming.
Prague out-of Hospital Cardiac Arrest (OHCA) study is a prospective randomized multicenter clinical study comparing use of prehospital intraarrest hypothermia, mechanical chest compression device, extracorporeal life support (ECLS) and early invasive investigation and treatment (coronary angiography/percutaneous coronary intervention [PCI]; pulmonary angiography/percutaneous embolectomy; aortography) in all patients with OHCA of presumed cardiac origin compared to standard of care. It is hypothesized, that above stated "hyperinvasive" approach might improve outcome of out-of hospital cardiac arrest victims.
The central purpose of this study is to compare the clinical outcomes of patients who suffered a cardiac arrest while hospitalized at the VA and were resuscitated after biphasic defibrillators were implemented in 2001 to clinical outcomes of patients who suffered cardiac arrest before 2001.
