Filter by:The goal of this observational study is to explore the optimisation and integration of a drone-delivered Automated External Defibrillator (AED) system into the pre-hospital response to out-of-hospital cardiac arrest. The study is being conducted by the University of Warwick and Welsh Ambulance Service National Health Service Trust (both in the UK) There are two separate packages of work. In work package 1 the investigators will interview people who have been involved in emergency (999) calls for cardiac arrest, asking them about their experiences with the call-handler and how they feel they might have responded if they had received an AED that had been delivered by a flying drone. In work package 2 the investigators will conduct simulated cardiac arrests. The participants in the study will make an emergency (999) call to a trained call-handler and, once the cardiac arrest is identified during the call, a drone will be activated from a distant location and fly up to 2km to the test site and deliver an AED. The investigators will record how long it takes to retrieve and attach the AED, and ask the participants for their views about the interaction with the call-handler, AED and drone.
The goal of this prospective observational study is to investigate the feasibility of using doppler point-of-care ultrasound on the femoral artery with a portable device to assess the presence of a pulse in patients suffering from cardiac arrest in the out-of-hospital environment. The main question is how often researchers are successful in acquiring the necessary ultrasound signal in the out-of-hospital environment.
This study examines the impact of emergency department (ED) management on short-term outcomes of nontraumatic adult out-of-hospital cardiac arrest (OHCA) patients. Conducted by a research team at National Taiwan University Hospital and its affiliated hospitals, including branches in Hsinchu and Yunlin, the study spans from January 2016 to August 2023. It focuses on a sequential population of patients, analyzing data like age, gender, medical history, prehospital care details (e.g., witnessed collapse, bystander CPR), and specifics of ED management. OHCA, with an incidence rate of 50-100 per 100,000 people, presents high mortality and severe complications, leading to significant healthcare expenditures. After resuscitation in the ED, only about one-fifth of patients achieve return of spontaneous circulation (ROSC). The prognosis for these patients remains grim, with a mere 5% experiencing favorable neurological outcomes. Understanding the mechanisms of OHCA, identifying risk factors, effective interventions, and the timing of ED treatments like vasopressors and electrocardiography are crucial. Patients post-OHCA often undergo a postcardiac arrest syndrome (PCAS), marked by cellular hypoxia and a consequential inflammatory response. Stability of vital signs and rapid ED interventions, including identifying OHCA causes and coordinating with specialists, are vital for short-term recovery. This study aims to determine if ED management and time-related factors from ROSC to various interventions (e.g., ECG, CT scans) affect short-term survival rates, including survival to hospital admission and survival after 1, 3, and 7 days. By retrospectively analyzing patient data, including Utstein Style prehospital cardiac arrest registry variables and emergency department management details, the study seeks to shed light on the crucial phase of post-resuscitation care. The ultimate goal is to improve survival rates and neurological outcomes in OHCA patients, emphasizing the need for more comprehensive research in this area
The goal of this prospective trial is to compare CPR skill and attitudes in adolescent students. The main question[s] it aims to answer are: - Does a gamified CPR experience improve CPR skill retention compared to standard classroom CPR training? - Does a gamified CPR experience improve attitudes/knowledge relating to barriers for women and minorities receiving CPR? Participants will - Answer pre-training questionnaires - Participate in CPR training - Participate in CPR skills testing on the day of training, and at 4-6 months - Answer post-training questionnaires Researchers will compare standard CPR classroom training to the novel gamified CPR training experience, which includes an interactive film, a CPR Trainer spring, and a mobile device app.
The objective of this observational study is to provide basic data for predicting and analyzing the occurrence and causes of delayed cognitive impairment, an important factor in the quality of life, among discharged patients who have received targeted temperature management therapy and experienced favorable neurological outcomes after out-of-hospital cardiac arrest. The main questions it aims to answer are: - Can we identify abnormal areas in the brains of patients with delayed cognitive impairment using Brain MRI or positron emission tomography (PET) imaging? - Is it possible to predict delayed cognitive impairment using biomarkers?
The purpose of this prospective observational cardiopulmonary resuscitation (CPR) registry is to track the use and clinical outcomes from emergency medical systems across the US and Europe that have implemented a system of care approach applied rapidly to cardiac arrest that includes using the combination of an impedance threshold device (ITD), and either manual active compression-decompression (ACD) CPR device or automated compression device, with a Head Up CPR device.
Preclinical studies suggest that argon (Ar) might diminish the neurological and myocardial damage after any hypoxic-ischemic insult. Indeed, Ar has been tested in different models of ischemic insult, at concentrations ranging from 20% up to 80%. Overall, Ar emerged as a protective agent on cells, tissues and organs, showing less cell death, reduced infarct size and faster functional recovery. More specifically, encouraging data has been reported in animal studies on cardiac arrest (CA) in which a better and faster neurological recovery was achieved when Ar was used in the post-resuscitation ventilation. More importantly, these benefits have been replicated in different studies, enrolling both small and large animals. Finally, ventilation with Ar in O2 has been demonstrated to be safe both in animals and humans. Based on this evidence, a clinical translation is advocated. Thus, the CardioPulmonary resuscitation with Argon - CPAr trial has been conceived. The aim of the CPAr trial is to evaluate feasibility and safety of Ar/O2 ventilation in patients resuscitated from CA. Activity endpoints will be also evaluated to assess effects of Ar.
This is a multicenter trial to establish the efficacy of cooling and the optimal duration of induced hypothermia for neuroprotection in pediatric comatose survivors of cardiac arrest. The study team hypothesizes that longer durations of cooling may improve either the proportion of children that attain a good neurobehavioral recovery or may result in better recovery among the proportion already categorized as having a good outcome.
The majority of survivors suffering an out-of-hospital cardiac arrest (OHCA) are those who initially present with a shockable rhythm, which is usually ventricular fibrillation (VF). When untreated, VF progresses to asystole over a short period of time so the percentage of those with a survivable rhythm also decreases with time. There is relatively little data exploring the initial rate of VF and the time course of its subsequent progression to a non-shockable rhythm. An understanding of this data will give a better picture of how potentially survivable rhythms (VF) change with time and guide the response times that are required to ensure arrival before VF deteriorates to asystole. The Investigators will use the UK OHCA outcomes database to examine the percentage of patients presenting with VF as the initial rhythm according to time since collapse in order to establish the rate at which VF deteriorates to asystole.
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).
