Filter by:The goal of this observational study is to investigate characteristics in out-of-hospital cardiac arrests (OHCA) related to sex differences. The main questions it aims to answer are: - are there possible differences in help provision by bystanders, cardiopulmonary resuscitation (CPR), pre-hospital treatment by emergency medical services (EMS)? - are there differences in the presence of shockable initial rhythm (SIR) and survival rates after OHCA at successive stages of treatment? Researchers will compare all emergency medical services treated resuscitations in Denmark between 2016 and 2021 to see if there are possible differences between sexes.
This study investigates the efficacy of landiolol versus placebo in patients with out-of-hospital cardiac arrest (OHCA) and refractory ventricular fibrillation (electrical storm).
Comparison of Manual Ventilation and Automatic Mechanical Ventilation during CPR, Pilot & Feasibility Study (CAVE-I trial)
Objectives/Hypotheses 1. Prehospital termination-of-resuscitation (TOR) rules were developed in North American and European sites. Whether they remained valid in different geographic, ethnic, and cultural background areas is still under debate. 2. Differences in characteristics of out-of-hospital cardiac arrests (OHCAs) and configurations of emergency medical service (EMS) between the Western and Asian countries, including relatively lower rate of presenting shockable rhythm (i.e. ventricular fibrillation / ventricular tachycardia; VF/VT), lower rates of bystander CPR, less advanced life support (ALS) implementation, and less public access defibrillators, might create potential threats to the prediction accuracy of TOR rules. 3. We aim to conduct a study to validate the performance of ever published TOR rules in Asian OHCA population, including non-traumatic, traumatic, and pediatric OHCA patients. Furthermore, assess the possible variables that may impact the performance of TOR rules. 4. We also aim to develop new TOR rules based on PAROS registry for Asia population, focusing on non-traumatic, traumatic, and pediatric OHCA patients, respectively.
Out-of-hospital cardiac arrest is a public health problem for which overall survival is below 10%. Post-cardiac arrest syndrome is the principal cause of death in intensive care units (ICU), due to refractory shock or brain injuries secondary to anoxia. Brain anoxia is responsible for severe neurological sequelae that may be aggravated by cerebral hypoperfusion during the first few hours after the return of spontaneous circulation. Current recommendations are to ensure that arterial blood pressure is sufficient for the perfusion of organs, but no minimum threshold mean arterial pressure (MAP) has been defined. In practice, most teams target a MAP of at least 65 mmHg. Several observational studies have shown a correlation between MAP and neurological prognosis, patients with a higher initial MAP having a better outcome. Recent pilot studies have demonstrated the feasibility of increasing the target MAP after cardiac arrest, but conflicting results have been obtained concerning patient prognosis. These findings may be explained by changes to the autoregulation of the brain after cardiac arrest, with a shift of the curve towards the right, or its abolition. Cerebral blood flow is dependent on MAP, and a target MAP of 65 mmHg for these patients may result in insufficient brain perfusion. Conversely, a too high MAP might cause brain lesions due to vasogenic edema, hemorrhagic complications or excess perfusion in conditions of diminished brain metabolism. An interventional study is required to evaluate the effect of increasing MAP on neurofunctional outcome after cardiac arrest. Given the data available for brain autoregulation, the correlation between MAP and prognosis, and the risks theoretically associated with a higher MAP, investigator plans to compare a standard threshold of MAP (≥ 65 mmHg) with a high threshold of MAP (≥ 90 mmHg). Investigator hypothesizes that a high MAP within the first 24 hours after cardiac arrest will improve neurofunctional outcome.
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.
The objective of this observational and retrospective study is to determine the predictive factors of in-hospital mortality following an out-of-hospital cardiopulmonary arrest (CPA) in the population under 18 years old. Data are collected from telephone calls and medical regulation records processed by the health call center of 2 french departments between January 1, 2019, and March 15, 2022. The medical records of the included patients will also be reread in order to obtain the patient's status at 30 days after the CPA. Detailed description: The literature reports numerous works evaluating the epidemiological characteristics of pediatric out-of-hospital cardiorespiratory arrest. An improvement in survival has been reported in the case of resuscitation guided by the operator in medical regulation before the arrival of the emergency services. Indeed, the regulation phase at the 15 center in France is of fundamental importance. Recent evolutions, notably with the creation of specific call-taking professions, show the importance attached to improving practices. The population concerned is characterized by children under 18 years of age, victims of an extra-hospital cardiorespiratory arrest. It is a retrospective study over three years and three months, multicentric, from the emergency service (SAMU) 57 and 69. The primary endpoint was the all-cause mortality at thirty days of the admission. The case report form (CRF) will collect the main aspects of telephone management at the 15 centers, out-of-hospital management by the emergency teams, and the personal characteristics of the emergency physicians and out-of-hospital responders (gender, age, family situation, etc.). The medical management in the emergency department and the first stages of in-hospital management will also be analyzed. The patients included who are still alive will receive a notification of non-objection by mail.
Comatose patients that are admitted to an intensive care unit after out-of-hospital cardiac arrest (OCHA) have a high mortality, particularly due to hypoxic-ischemic neurologic injury. These patients often require vasopressors to maintain mean arterial pressure (MAP), but it is unclear what level of MAP should be aimed for. The objective of the study is to evaluate whether cerebral blood flow (CBF) and cerebral metabolism can be increased by maintaining MAP at a higher level than that used in clinical practice. The study will include twenty comatose patients within two days following resuscitation after OCHA. In the study, MAP is adjusted by infusion of noradrenaline, to a low, moderate, and high level for a short time. The low level of MAP used in the study, corresponds to the level aimed for in clinical practice. The CBF will be evaluated on the neck using ultrasound.
Time to defibrillation is the most important predictor of survival in cardiac arrest. Recent studies have shown that unmanned drones can deliver AEDs to the site of real life out-of hospital cardiac arrest (OHCA) before ambulance arrival. Although an AED is available in the close vicinity, they are seldom used. The overall aim of this study is to provide an interventional bundle directed towards the dispatch centre and evaluate referral of callers to retrieve drone-delivered AEDs so that they may be attached in cases out-of-hospital cardiac arrest.
The purpose of this pilot feasibility study is to evaluate the ability of the Perfusion Index to predict the return to spontaneous circulation of the out-of-hospital cardiac arrest patient during cardiopulmonary resuscitation. The performance of the perfusion index will also be compared to the current gold standard, end-tidal CO2 (EtCO2).
