Filter by:The goal of this study is to show the superiority in survival at hospital admittance and in neurological outcome on hospital discharge of continuous mechanical chest compression using LUCAS device versus manual chest compressions in patients who suffered an out-of-hospital cardiac arrest.
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 purpose of this study is to assess the feasibility of hemofiltration in patients resuscitated from cardiac arrest. Cardiac arrest is the loss of mechanical activity of the heart including the loss of detectable pulse, or spontaneous breathing. When heart function is restored, the cells of the body release molecules into the blood that cause inflammation, unstable blood pressure, organ dysfunction and death. Hemofiltration is a technique of washing the blood to remove fluid and molecules from it. Hemofiltration is a proven therapy for renal failure, but is considered investigational for treatment after resuscitation from cardiac arrest. Some experts believe that hemofiltration after heart function is restored can remove inflammation from the blood, maintain blood pressure and organ function. Others believe that intravenous fluid and medications are sufficient to maintain blood pressure and organ function. Since the inflammation that occurs after restoration of heart function lasts, the investigators continue hemofiltration for up to 48 hours. Whether hemofiltration or intravenous fluids and medications is better is not known. The investigators are checking if they can wash the blood of patients resuscitated from cardiac arrest before the investigators can begin a large randomized trial to test whether hemofiltration improves their outcome. The investigators are testing this by randomly allocating patients resuscitated from cardiac arrest to receive low volume hemofiltration, high volume hemofiltration, or intravenous fluids and medications alone. The null hypotheses are that less than 80% of eligible patients will be enrolled, and that less than 80% of enrolled patients will undergo low-volume or high-volume hemofiltration (HF) for at least 80% of 48 hours.
An international airway management expert group has recently developed an Utstein-style template for uniform reporting of data from prehospital advanced airway management. Implementing and validating the template will result in a high quality dataset and allow for research cooperation and comparison of airway management practice between EMS systems, and across different patient populations. Such a dataset will hopefully contribute to new knowledge in the field of prehospital advanced airway management.
The study Premature Termination of Resuscitation in Survivors of Cardiac Arrest focuses on using innovative knowledge translation strategies to improve appropriate neuroprognostication for survivors of cardiac arrest and prevent premature termination of life sustaining therapies. This is important because any early gains achieved during resuscitation will be nullified if clinicians terminate life-sustaining therapies prematurely based on inadequate prognostic information. An effective translation strategy for neuroprognostication will result in improved physician adherence to evidence-based medicine and an increase in the proportion of patients surviving to achieve a good neurological outcome following cardiac arrest.
There is a correlation between hospital mortality and changes in markers of tissue perfusion, lactate, and venous oxygen saturation and carbon dioxide gradient.
Inexperienced rescuers may encounter severe problems in an unconscious patient in opening and maintaining an upper airway patent. Gaining evidence which ventilation technique may be most efficient and safe is of utmost importance to potentially improve outcome during cardiopulmonary resuscitation.
The aim of this study is to investigate the predictive value of the presence or absence of cardiac activity by bedside ultrasound during cardiac arrest. The investigators anticipate based on previous research that patients who suffer a cardiac arrest and have cardiac activity on bedside ultrasound will have a greater chance of surviving to hospital admission. The investigators hypothesis is that the mortality rate in patients in cardiac arrest with no cardiac activity by ultrasound will have a mortality rate of 100%.
Cardiac surgery including hypothermic cardiac arrest (HCA) commonly involves perioperative transfusion of allogeneic blood products which is associated with increased morbidity and mortality. In this retrospective analysis, the investigator aimed to evaluate the effect of a thromboelastometry-guided treatment algorithm promoting fibrinogen concentrate as first line hemostatic agent on the perioperative use of allogeneic blood products.
This study is designed to determine if there is any relationship between performing an abdominal ultrasound on patients who present with hypotension and their clinical outcomes (as measured by 7, 30 day and discharge mortality).
