Filter by:The aim is to describe the incidence, characteristics, risk factors and outcome of complications acquired under mechanical ventilation (called ventilator-associated events) according to the new CDC criteria, in a population of patients admitted in intensive care unit after cardiac arrest.
The purpose of this pilot interventional study is to collect preliminary data on administering packed red blood cell (PRBC) during cardiac arrest (CA). The primary objective is to assess the feasibility of PRBC transfusion during cardiac CA to help optimize the methods required to augment cerebral and other vital organ oxygen delivery during cardiopulmonary resuscitation (CPR). The secondary objectives are to assess the effect of PRBC transfusion during prolonged cardiac arrests on cerebral oxygenation, end tidal carbon dioxide (ETCO2), return of spontaneous circulation (ROSC), survival to discharge, biomarkers of neural injury and inflammation, and neurological outcomes at hospital discharge, 30 days post-CA, and 90 days post-CA.
Because of its high incidence, it is essential to determine the neurological prognosis after cardiac arrest. However, there is not much information to guide post-cardiac arrest care. Also, dynamic monitoring of the state of the brain can help provide information about the patient's prognosis other than previously described serum biomarkers. Therefore, the researchers will monitor postcardiac arrest patients in the intensive care unit for 48 hours by electroencephalogram and cerebral oximetry and collect blood samples for serum biomarkers: neuron-specific enolase (NSE), human neurogranin (NRGN) and human trigger receptor expressed on myeloid cells (TREM-2), which are associated with neuronal damage. And investigate the relation of these data to mortality.
The purpose of this pilot interventional study is to collect preliminary data on administering magnesium sulfate as a neuroprotective medication in patients who achieved Return of Spontaneous Circulation (ROSC) following Cardiac Arrest (CA). The primary aims are to assess the feasibility and safety of administering magnesium and measure serum markers of neuronal injury at prespecified time points in the post-cardiac arrest period. Because this is a pilot study with a limited sample size, the primary objective is to evaluate the precision and stability of the collected measures to inform the design and formal analysis in a larger trial.
Aim This was a population-based retrospective cohort study of OHCA. This study intends to retrospectively analyze the data of pre-hospital emergency system in Guangzhou for 10 years, explore the incidence trend of OHCA in Guangzhou for 10 years; Through further analysis, we try to explore the time distribution characteristics of OHCA in order to understand the epidemiological characteristics and rules of OHCA in super large cities in southern China. Methods The pre-hospital traffic data in the main urban area of Guangzhou Emergency Medical Command Center database from 2011 to 2020 were collected. The cases diagnosed as "cardiac arrest" and "sudden death" were screened, and the cases with non-cardiac causes in the diagnosis were deleted. The crude incidence rate and age-standardized incidence rate of OHCA were calculated. Joinpoint software was used to calculate the changing nodes in the OHCA incidence trend, and the AnnualPercent Change (APC) and Average AnnualPercent Change (Average AnnualPercent Change, APC) of OHCA incidence were calculated. AAPC). The OHCA data were grouped according to the six main urban areas, and the crude incidence rate, ASIR and changing trend of the six main urban areas were calculated. The data of OHCA were grouped by age, and the crude incidence rate, ASIR and changing trend of each age group were calculated. The data information was divided into groups according to 24 hours a day, 7 days a week, and four seasons. The number of OHCA cases in different time periods was statistically described. The data were imported into SPSS 26.0 for analysis, and Mann-Kendall test was used to evaluate the statistical significance of the time trend. Time rhythm variability was tested for mean distribution using chi-square goodness of fit test.
Some of the patients affected by Out-of-hospital cardiac arrest (OHCA) with ventricular fibrillation (VF)/ventricular tachycardia (VT) do not respond to initial defibrillation. The survival decreases with number of defibrillations required to terminate VF/VT. In 2022, one prospective cluster randomized trial showed increased survival among (OHCA) patients in refractory VF using Double Sequential Defibrillation (DSD). To evaluate feasibility and safety this randomized pilot trial will compare the effect of double defibrillation strategy initiated as soon as possible after the first defibrillation with continued resuscitation using standard defibrillation, in patients with Out of Hospital Cardiac arrest (OHCA). The results from this pilot trial will form the basis for design of a larger multicenter survival study.
To describe and measure diastolic and systolic femoral arterial pressure during medical cardiac arrest. To define baseline measures. To describe and measure arterial blood pressure after placement of an ITD device. To observe the diastolic pressure immediately prior to return of spontaneous circulation. To quantify and describe the effects of intravenous adrenaline on arterial blood pressure in cardiac arrest.
The goal of this observational study is to determine whether specific advanced MRI measures are associated with functional outcomes in patients who are comatose after cardiac arrest. The main question[s] it aims to answer are: Aim 1: Determine if stimulus-based functional MRI (fMRI)-measured activations are independently associated with favorable neurological outcomes after cardiac arrest Aim 2: Determine if resting state functional MRI (rs-fMRI)-measured functional network connectivity is independently associated with favorable neurological outcomes after cardiac arrest. Aim 3: Determine if diffusion tensor imaging (DTI)-measured white matter integrity is associated with favorable neurological outcomes after cardiac arrest. Participants will undergo advanced MRI sequences at time of clinical MRI, and will be followed for 6 months post-arrest.
Cognitive aids are decision support tools that present prompts to encourage recall of information, thus freeing up mental resources to increase the likelihood of desired behaviors. Cognitive aids have been trialed in different forms for use during resuscitation, including pocket reference cards and digital apps. Simulation-based studies of cognitive aid used during cardiac arrest events have shown improved adherence to guidelines, improved time to completing critical tasks, and reduced rate of critical errors. Unfortunately, existing pocket reference cards and mobile apps have significant flaws - they all require providers to search through content to identify relevant information. In the proposed study, we will evaluate the impact of an enhanced system, InterFACE-AR, which provides role-specific decision support to the team leader and medication nurse through AR devices, while concurrently optimizing team situational awareness by displaying a roadmap for patient care on the LCD screen. Clinical data will be collected from the mobile app on a tablet used by the charting nurse. The trial aims to assess the individual and combined effectiveness of InterFACE-AR components (i.e. AR devices and LCD screen) on adherence to AHA resuscitation guidelines during simulated cardiac arrest by conducting a randomized controlled trial with a factorial design.
The scientific goals of the project: 1. ultrasound assessment of the incidence of clotting in deep veins in patients after cardiac arrest during resuscitation and after the declaration of death; comparison to the incidence of clotting in the heart cavities 2. comparison of resuscitation results in patients with and without clotting detected in deep veins during resuscitation 3. determining the time from cardiac arrest to the occurrence of clotting in deep veins; comparison to the time until clotting occurs in the heart cavities Confirmation of the usefulness of the ultrasound-detected clotting in deep veins during resuscitation in assessing the severity of cardiac arrest and the prognosis of resuscitation, which is the aim of the project, will have an impact on international guidelines for determining the prognosis and potential futility of resuscitation.
