Filter by:Out-of-hospital cardiac arrest without resumption of spontaneous circulatory activity despite advanced medical resuscitation is considered refractory. Under certain well-defined conditions, today in many cities around the world and particularly in Paris, it benefits from resuscitation called ECPR (extracorporeal cardiopulmonary resuscitation). This technique consists of the installation of an extracorporeal membrane oxygenation (ECMO) device allowing organ perfusion while waiting for a resumption of cardiac activity. Since 2011, the Paris SAMU (SAMU 75) has set up a team capable of implementing ECPR for refractory out-of-hospital cardiac arrests. This team based within the SAMU of Paris at the Necker hospital (ECMO team) composed of an emergency doctor or anesthesiologist-resuscitator, a nurse anesthetist and an ambulance driver intervenes in Paris and its nearby region at the request of medical regulation. Given the growing development of this activity, it is essential to measure its effectiveness in real-life conditions.
Anxiety, depression and cognitive impairment symptoms are common among cardiac arrest survivors. This randomized clinical trial will test whether an internet-based lifestyle intervention administered through a web app can foster anxiety and depression symptoms in patients who survived an out-of-hospital cardiac arrest and suffer from these symptoms
Cerebral lesions are responsible for two thirds of deaths in patients admitted to intensive care following cardiac arrest. Patients with neurological lesions should be the priority target for neuroprotective interventions, which are the cornerstone of post-cardiac arrest care (allowing a reduction in the burden of care for patients without this type of lesion). Furthermore, these interventions must be based on a precise assessment of the severity of these brain lesions: carrying out neuro-protective interventions in patients without brain lesions exposes these patients to unnecessary treatment potentially associated with adverse effects without any possible benefit. However, the early assessment of neurological prognosis, particularly on admission to intensive care, is an area where there is little research and where it is not possible to obtain a precise and reproducible assessment. Several tools can be used to assess this prognosis at an early stage: anamnesis and characteristics of the cardiac arrest and the patient's comorbidities, imaging, electrophysiology and biomarkers. To assess the predictive value of early biomarker testing in patients resuscitated after cardiac arrest, whatever the cause, the investigators plan to conduct a prospective observational multicentre trial. It is important to bear in mind that the aim of this study is not to assess the long-term prognosis of patients suffering cardiac arrest in order to take measures to limit or discontinue active therapies, but simply to provide a reliable tool, simple and quick to use, in order to be able to identify a sub-population of patients who should be the subject of preferential neuro-protection measures, and conversely to simplify management (moderate temperature control, early cessation of sedation, early extubation) for patients with no neurological lesions.
A prospective, multicenter, randomized clinical trial in two tertiary pediatric emergency department. It will assess, amongst pediatric healthcare teams, whether the use of augmented reality supportive devices improves adherence to American Heart Association (AHA) advanced life support guidelines and performance, while reducing medication errors, when compared to groups using the AHA pocket reference card (control) during standardized, simulation-based, pediatric in-hospital cardiac arrest (IHCA) scenarios. Seventy participants will be randomized. The primary endpoint is the time to first dose of epinephrine.
This study is a Phase 3, multi-center, Bayesian Adaptive Sequential Platform Trial testing the effectiveness of different prehospital airway management strategies in the care of critically ill children. Emergency Medical Services (EMS) agencies affiliated with the Pediatric Emergency Care Applied Research Network (PECARN) will participate in the trial. The study interventions are strategies of prehospital airway management: [BVM-only], [BVM followed by SGA] and [BVM followed by ETI]. The primary outcome is 30-day ICU-free survival. The trial will be organized and executed in two successive stages. In Stage I of the trial, EMS personnel will alternate between two strategies: [BVM-only] or [BVM followed by SGA]. The [winner of Stage I] will advance to Stage II based upon results of Bayesian interim analyses. In Stage II of the trial, EMS personnel will alternate between [BVM followed by ETI] vs. [Winner of Stage I].
Butylphthalide (NBP) is a neuroprotective medication capable of ameliorating neurological dysfunction induced by ischemia, hypoxia, and reperfusion injury in the brain. However, evidence regarding the improvement of neurological function prognosis in patients with return of spontaneous circulation (ROSC) after cardiac arrest (CA) by NBP is limited. This study aims to evaluate the safety and efficacy of NBP treatment in improving the neurological function prognosis of patients with ROSC after CA.The study will be a single-center, randomized, double-blind, placebo-controlled trial. The sample size is estimated to be 100 patients. Eligible patients will be randomly allocated in a 1:1 ratio to receive either NBP or placebo treatment daily for a duration of 14 days. The initial administration of NBP or placebo treatment will commence within 6 hours after ROSC following CA. The primary outcome is the proportion of patients with Cerebral Performance Category (CPC) scores of 1-2 at 90 days after randomization in each group. The primary safety outcome is the percentage of severe adverse events occurring during the 14-day treatment period. This trial will determine the efficacy of NBP in providing neuroprotective effects for patients with ROSC after CA.
Despite advances in post-resuscitation care of patients with cardiac arrest (CA), the majority of survivors who are treated after restoration of spontaneous circulation (ROSC) will have sequelae of hypoxic-ischemic brain injury ranging from mild cognitive impairment to a vegetative state. Current recommendations suggest using a multimodal approach to predict poor prognosis, meaning combining markers together. Yet, a substantial proportion of patients do not have a clear prognostic evaluation even when applying the latest ESICM recommendations algorithm published in 2021. It is therefore important to identify new prognostic markers to predict both unfavorable and favorable outcomes. Data regarding the pathophysiological mechanisms of post-anoxic encephalopathy suggest a diffuse anoxo-ischemic injury. However, post-mortem neuropathology data suggest that these lesions do not uniformly affect neuroanatomical structures, with some regions (especially hippocampal and insular) appearing more sensitive to anoxia. Conversely, the brainstem appears less affected by anoxic lesions. Under physiological conditions, there are interactions between the heart and the brain, and between the brain and the heart mainly related to the autonomic nervous system, through interactions between central cortical control structures (especially insular) and brainstem structures (at the level of the bulb) and peripheral structures of the heart. Exploring the pathophysiological mechanisms of heart-brain interactions post-CA could thus help better understand the pathophysiology of anoxo-ischemic encephalopathy, before considering potential therapeutic targets. Furthermore, this heart-brain dysfunction could have prognostic value. Indeed, recent studies in healthy subjects and patients with consciousness disorders suggest that autonomic nervous system activity measured by brain-heart interactions could be a reliable marker of consciousness and cognitive processing. These coupled heart-brain interactions can be evaluated through synchronous electroencephalogram (EEG) and electrocardiogram (ECG) recordings, as there are coupled interactions between the signals of these two organs. The existence of abnormal brain-heart coupling could be associated, on the one hand, with the severity of post-anoxic encephalopathy, and on the other hand, with neurological prognosis in patients with persistent coma post-CA. This ancillary study of a multicentre prospective cohort "HEAVENwARd study" (NCT06044922) will assess the prevalence and prognostic value of bilateral brain-heart interactions in comatose patients after CA.
The study investigates the influence of non-synchronized bag-device-ventilation and intermittent positive pressure ventilation (IPPV), as recommended in the current resuscitation guidelines of the European Resuscitation Concil (tidal Volume (Vt) = 5-6 mL/kg body weight, respiratory rate = 10 min-1) and Chest Compression Synchronized Ventilation (pInsp = 40 mbar; respiratory rate = chest compression rate) with regard to achieving a sufficient tidal volume and the tightness of various supraglottic airway devices (laryngeal mask, i-Gel-laryngeal mask, laryngeal tube) and endotracheal intubation.
Out-of-Hospital Cardiac Arrest remains a major public health problem, resulting in high mortality largely related to multiple organ failure and poor neurological outcomes due to brain anoxia. The pathophysiology of organ dysfunction after resuscitated out-of-hospital cardiac arrest involves ischemia-reperfusion processes. Remote ischemic conditioning is a therapeutic strategy used to protect organs against the detrimental effects of ischemia-reperfusion injury. The objective of the present trial is to determine whether remote ischemic conditioning performed early after out-of-hospital cardiac arrest can decrease mortality, or multiple organ failure and/or severe neurological failure.
Background: Cardiorespiratory arrest (CPA) occurs when there is a cessation of cardiac mechanical activity, typically diagnosed by the absence of consciousness, pulse, and breathing. Actions taken in response to CPA include recognizing the condition and promptly notifying emergency medical services, initiating Cardiopulmonary Resuscitation (CPR) maneuvers, and employing an Automated External Defibrillator (AED). Survival rates are directly influenced by the time elapsed between CPA onset and the initiation of CPR maneuvers, as well as the quality of these interventions Hypotheses: Online education in CPR maneuvers is an effective and efficient tool for training individuals from the general population on how to respond to cardiac arrests Objectives: The primary aim of this study is to assess the efficacy of online CPR and AED training within the general population of the province of Tarragona. Specific objectives include: 1) evaluating participants' theoretical and practical CPR skills in the short and medium term following online training, and 2) exploring the experiences of individuals who have completed the online training and simulation sessions using qualitative methodology. Methodology:This study will unfold in several phases: 1) Online CPR-AED training and assessment of theoretical knowledge acquisition; 2) Evaluation of acquired practical CPR skills (know-how) within a simulation environment, conducted on a subset of the population completing phase 1;3)Analysis of the experiences of a subset of individuals who have participated in the preceding two phases, employing qualitative methodology Variables and determinations:The primary response variable for phase 1 will be the difference in scores obtained from the online questionnaire between the final (post-training) and initial (pre-training) assessments. In phase 2, the main variable will be the pass/fail categorization of scores in the simulation. This evaluation will be conducted by two members of the Advanced Clinical Simulation Unit at Joan XXII Hospital using a predefined checklist. Throughout the various phases of the study, socio-demographic data and course performance data will be taken into account Expected results: The research team for this study aims to ascertain the efficacy and effectiveness of online CPR-AED training within the general population. Furthermore, the study aims to provide evidence regarding the optimal duration and frequency for repeating such training. Applicability and Relevance: This proposal advocates for a significant and innovative project, given the dearth of literature on this topic. While there are existing indications and studies on CPR-AED training among specific populations such as students and healthcare professionals, the presented proposal seeks to broaden the scope of training to encompass the general population.
