Filter by:The Discover In-Hospital Cardiac Arrest (IHCA) study is a multicenter, prospective observational study aimed at better understanding variations in practice for the post-in-hospital cardiac arrest patient.
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 purpose of the research (pilot study) is to determine the impact of the use of the autotransfusion device on hemodynamic parameters during resuscitation. 24 people will be included in the pilot study (12 people will be included in the intervention group - with the usage of "autotransfusion socks" during resuscitation and 12 people in the control group - without "autotransfusion socks"). Investigators will compare the hemodynamic parameters and also neurological outcome between both groups.
The goal of this observational study is to establish the protocol of systemic analysis of the causes of non-traumatic cardiac arrest in young patients. The main questions it aims to answer are: - Whether the protocolized classification of cardiac arrest minimizes the proportion of unknown causes and mis-classification in young cardiac arrest patients? - Whether the incorporation of genetic tests in the identification protocol of arrest cause helps the recognition of sudden arrhythmic death syndrome in young cardiac arrest patients? Participants will be asked to received serial examinations including genetic analysis to explore the cause of cardiac arrest.
The investigators want to investigate the effect of rTMS on working memory measured by the N-back task. This is a single case experimental design, ABAB.
The goal of this clinical trial is to explore the effect of FDA-approved antiseizure drugs in the brain connectivity patterns of severe and moderate acute brain injury patients with suppression of consciousness. The main questions it aims to answer are: - Does the antiseizure medication reduce the functional connectivity of seizure networks, as identified by resting state functional MRI (rs-fMRI), within this specific target population? - What is the prevalence of seizure networks in patients from the target population, both with EEG suggestive and not suggestive of epileptogenic activity? Participants will have a rs-fMRI and those with seizure networks will receive treatment with two antiseizure medications and a post-treatment rs-fMRI. Researchers will compare the pretreatment and post-treatment rs-fMRIs to see if there are changes in the participant's functional connectivity including seizure networks and typical resting state networks.
This study aims to optimize the treatment of out-of-hospital cardiac arrest (OHCA) by focusing on neurological outcomes through Bispectral Index (BIS) monitoring. It will evaluate the feasibility of BIS monitoring in the prehospital phase, assess the need for sedation based on BIS values, and examine the timing of interventions in ICU (intensive care unit) settings to identify irreversible Hypoxic-Ischemic Brain Injury (HIBI).
In order to monitor and improve cardiopulmonary resuscitation(CPR) quality, there is need for tools that provide real time feedback to responders. The use of invasive arterial pressure monitoring and end tidal carbon dioxide (ETCO2) as quality measures of CPR. Invasive pressure measurements are timeconsuming and cumbersome in resuscitation situations, and are very rarely practical. ETCO2 measurements require presence of a capnometer with an advanced airway. High quality chest compression will result inETCO2 between 2-2.5KPa. A rapid increase in ETCO2 on waveform capnography may enable ROSC to be detected while continuing chest compression and can be used as a tool to withhold the next dose of bolus adrenaline injection. Pulse oximetry, which noninvasively detects the blood flow of peripheral tissue, has achieved widespread clinical use. It was noticed that the pulse waveform frequency can reflect the rate and interruption time of chest compression(CC) during cardiopulmonary resuscitation(CPR). The perfusion index (PI) is obtained from pulse oximetry and is computed as the ratio of the pulsatile (alternating current) signal to the non-pulsatile (direct current) signal of infra-red light, expressed as a percentage;PI =ACIR/DCIR∗100% (i.e. AC = pulsatile component of the signal, DC = non-pulsatile component of the signal, IR = infrared light). PI shows the perfusion status of the tissue in the applied area for an instant and a certain time interval. The PI value ranges from 0.02% (very weak) to 20% (strong).Peripheral PI has been proposed for different clinical uses with some applications in critical patients. The purpose of this study is to evaluate the role of pulse-oximeter derived perfusion index for high quality CPR and as aprognostication tool of ROSC during in-hospital cardiac arrest in comparison to ETCO2 reading.
The goal of this randomized controlled trial is to compare prehospital ventilation strategies in out-of-hospital cardiac arrest. The intervention group is automatic ventilation and the control group is manual ventilation. The main questions it aims to answer are: 1. How does automatic ventilation affect OHCA patients' survival and prognosis comparing to manual ventilation. 2. What are the differences on resuscitation qualities between automatic ventilation and manual ventilation.
The objective of this study is to estimate the feasibility and safety of early weaning from ICU treatment in patients after cardiac arrest and an early (< 12 h) favourable EEG pattern (indicating no or mild postanoxic encephalopathy).
