Active clinical trials for "Heart Arrest"

The objective of this study will be to compare humeral and tibial IO needle insertions to peripheral IV access during cardiac arrest. Hypothesis There is a difference in first attempt success of tibial IOs compared to humeral IOs or peripheral IV among cardiac arrest patients. This was a randomized trial of adult patients experiencing a medical OOHCA where resuscitation efforts were initiated. Patients were randomized to 1 of 3 routes of vascular access. Prior to every shift, paramedics were distributed a randomly selected note card indicating the prescribed route for vascular access: tibial IO, humeral IO, or peripheral IV. The selected method applied to the first attempt at vascular access only. Paramedics received intensive training and exposure to all three methods prior to study initiation. The primary outcome was first attempt success defined as secure needle position in the marrow cavity or a peripheral vein with normal fluid flow. Needle dislodgement during resuscitation was counted as a failure to maintain vascular access. In order to detect a statistical difference in the frequency of first attempt success a minimum of 50 patients for each arm of the study were needed.

The major goal of this project is to determine whether the use of physiologic doses of corticosteroids will decrease time to shock reversal, alters the inflammatory cascade, and alters microcirculatory flow in post-cardiac arrest patients.

New single use laryngoscope metal blades are available for intubation. This type of blade is safer than the reusable ones concerning the interhuman cross infection risk. No clinical studies have compared the two types of blades in the emergency context. The primary aim of this study is to demonstrate that single use blades are as efficient as the reusable ones concerning intubation conditions.

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.

Survival from out-of-hospital cardiac arrest is time critical and diminishes rapidly without appropriate intervention. Bystander CPR at least doubles the chances of survival and the additional use of a public access defibrillator (PAD) can again double overall survival rates. PADs are designed to be easy and simple to use, but whether untrained bystanders can use them safely and effectively is unknown. This study will aim to assess the ability of untrained bystanders to deploy a PAD in a simulated cardiac arrest.

Emergency medical Services Copenhagen has developed a machine learning model that analyzes the calls to 1-1-2 (9-1-1) in real time. The model are able to recognize calls where a cardiac arrest is suspected. The aim of the study is to investigate the effect of a computer generated alert in calls where cardiac arrest is suspected. The study will investigate whether a potential increase in recognitions is due to machine alerts or the increased focus of the medical dispatcher on recognizing Out-of-Hospital cardiac Arrest (OHCA) when implementing the machine if a machine learning model based on neural networks, when alerting medical dispatchers will increase overall recognition of OHCA and increase dispatch of citizen responders. increased use of automated external defibrillators (AED), cardiopulmonary resuscitation (CPR) or dispatch of citizen responders in cases of OHCA on machine recognised OHCA vs. medical dispatcher recognised OHCA.

Determination the success rate of CPR on adults in Emergency room and predicting the factors that makes CPR is successful.

Single center randomized-controlled trial in out-of-hospital cardiac arrest (OHCA) patients. This study will investigate the feasibility and utility of the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) procedure using a REBOA catheter device in patients who have experienced an OHCA and have not regained return of spontaneous circulation (ROSC).

Rationale: Early detection and timely interventions are important determinants of clinical outcome in people with acute illness. Adverse outcomes including unplanned transfer to intensive care (ICU), cardiac arrest and death are usually preceded by acute physiological changes manifesting as alterations in vital signs. Usage of early warning scores (EWS) based on bedside vital sign observations may help early detection, improve outcome of patients and reduce healthcare cost. EWS which are effective in predicting deteriorating patients developed in high income countries have been shown to lose sensitivity and specificity when applied to a low income setting. It is imperative to explore the usefulness of EWSs in Sri Lanka. If the results are positive, widespread adaptation of these scores can significantly contribute to improved patient outcome, better utilization of ICU services and cost effective healthcare provision. Objectives: To describe the demographic characteristics of cardiac arrest patients and the availability of physiological variables for calculation various EWSs in DGH, Moneragala To validate an early warning score suitable for patients at DGH, Moneragala To examine the effectiveness of the selected EWS at improving pre-defined patient outcomes Proposed methodology: Study I: All clinical variables and patient characteristics of past two years collected retrospectively from BHTs. Vital signs and laboratory measurements 24 and 48 hours before cardio respiratory emergency and at admission to hospital will be extracted. The availability of variables required for the calculation of various EWSs will be noted. Study II: All consecutive inpatient admissions for three months to all units except intensive care unit at DGH, Moneragala will be included to the study, prospectively. Data will be collected from bed head tickets using pre-defined data sheets by nominated medical/ nursing officers daily. Demographic details and physiological data will be recorded on admission to ward. Physiological data for seven EWS will be collected twice daily by these medical/nursing officers. Study III: Training will be given for the staff to identify patients getting worse using the newly validated EWS. The outcome of this will be measured with information obtained from Study II. Ethical clearance obtained from the Ethics review Committee of the Faculty of Medicine, University of Colombo (EC-15-034).

Non-convulsive seizures (NCS) following cardiac arrest are common and are associated with worse neurologic outcomes and increased mortality. More prolonged seizures (status epilepticus) are associated with worse outcomes. Earlier diagnosis and treatment of seizures may lead to earlier termination of seizures and decreased seizure burden. This study will evaluate whether bedside intensive care unit (ICU) provider interpretation of a type of EEG called DSA EEG can be used by non-neurologists to diagnosis seizures more rapidly than continuous EEG's routinely read by neurologists.
