Active clinical trials for "Out-of-Hospital Cardiac Arrest"

Out-of-hospital cardiac arrest rate is common problem, because of high mortality rate. It is not clear incidence rate, epidemiology and outcomes in Lithuania and Kaunas city included.

Observational study of all out-of-hospital cardiac arrest during 6 months in regional areas of Helsinki University Hospital and Kuopio University Hospital from activation of EMS system until follow up to 6 months of survival.Simultaneous observation of out-of-hospital cardiac arrest primary survivors admitted to all Finnish ICUs.

The aim of the study is to analyse if live video as a supplement to emergency calls can improve medical dispatchers' situation awareness and enhance the assistance they provide including provision of pre-hospital resources. Focus will also be on evaluating the unconscious patient and improve CPR quality. The general experience from the medical dispatcher and the person calling the emergency number regarding the feasibility of adding live video will also be analysed.

The aim of this study is to construct multi-center post-cardiac arrest care registry that can be used for data warehousing and clinical research.

Dispatcher-assisted cardiopulmonary resuscitation is a complex, nonvisual procedure that is challenging for the dispatcher. The aim was to explore the medical dispatchers' perception of bystanders' responses and dispatchers' reflections about the added value of visual information in out-of-hospital cardiac arrests (OHCA) situations.

The hypothesis is: In patients after an out of hospital cardiac arrest, treated with therapeutic hypothermia (33°C) will be found significantly more microcirculatory abnormalities, compared to the same group of patients treated with 36°C.

Out of hospital cardiac arrest is associated with a poor prognosis. The aim of this study is to provide a better understanding of perturbations of iron metabolism after cardiac arrest and to analyze the impact on clinical centered outcome.

Background: Foreign body airway obstruction (FBAO) is often described as an uncommon cause of Out of Hospital Cardiac Arrest (OHCA) accounting for approximately 1.4% of all OHCA. Reported incidents rates of FBAO causing cardiac arrest are unclear, and first aid by layperson are not well described. The aim of the epidemiological part of the study is: to investigate information on actions taken by EMS-personnel and laypersons to investigate outcomes of hypoxic Cardiac Arrest due to foreign body airway obstruction in Denmark to increase overall survival. propose new guidelines and strategies to increase survival from OHCA caused by FBAO. The aim of advanced text-string search algorithm part of the study is - To investigate if an advanced text-string search algorithm can identify FBAO in medical records with high sensitivity Methods: National data will be collected from the verified 2016-2019 Danish OHCA register, and cases with FBAO prior to OHCA will selected via a direct marking by external validation and advanced text search. Patients reported as indisputably deceased (late signs of death) was excluded. Incidence rates per 100.000 citizens, survival rates to hospital and first aid actions by layperson are presented. A pilot study have been conducted in regional data from 2016-2019 and the study group have concluded that, a national study is feasible with the current amount of data and the used methodology. Expected outcome: This study will enable targeted campaigns aimed at increasing survival from OHCA caused by FBAO. Potential campaigns might target the food items provided to potential vulnerable groups and guide focus for first aid recommendations. Further, with a deeper understanding of which airway management procedures most often are successful, it will be possible to improve EMS treatments of vulnerable groups. Finally, a novel method of extracting information from the electronic medical records will be developed creating the foundation for future works on other prehospital conditions

While regular exercise is known to prevent cardiovascular disorders, exercise might also trigger acute cardiac events such as cardiac arrest. This study examines the incidence, prognosis and outcomes of out-of-hospital cardiac arrest (OHCA) related to exercise in the general population of Denmark. This retrospective cohort study examins all OHCAs in the Danish Cardiac Arrest Registry from 2016 to 2019 in Denmark. OHCA related to exercise were identified in the nationwide electronic database and coupled to the patient register. OHCA related to exercise was defined as occurring during or up to one hour after exercise of moderate or vigorous intensity. Descriptive statistics are used together with an adjusted multivariate logistic regression model to assess predefined factors of interest.

Background: OHCA is a rare condition for children and young adults. Overall incidence rates are reported as 3.3-5.97 per 100.000 inhabitants. Previous studies from different data sources have identified a diverse and slightly incompatible etiologies. The purpose of this investigation was to analyze presumed etiologies of pediatric OHCA and report incident and survival rates. Further the investigators wish to present central characteristics of pediatric OHCA in Denmark. Methods: Data will be collected from the verified 2016-2019 Danish OHCA register. Inclusion criteria were age ≤ 16 years at the time of the event. All included EMS reports will read by two authors [MGH and TWJ] and the presumed reversible cause assigned to each case. Incidence rates per 100.000 citizens, survival rates to hospital, initial rhythm, use of AED by laypersons, EMS treatment and presumed etiology are reported. To test feasibility a study was conducted in 2018, on the 56 verified cases of children with OHCA was reported in the capital region of Denmark in 2016-2018 (among 1.8 million inhabitants). Incident rates were 0.83-1.34 per 100.000 inhabitants per year. Preliminary data show survival to hospital was 46% which was markedly higher than the adult population (28%, p = 0.002). The most common cause of OHCA was hypoxia (50%) followed by trauma/hypovolemia (14%) and others (7%). Approximately 23% did not present with an apparent etiology. Hereditary disorders as the primary cause was noted in 7% of the cases. The conclusion from the feasibility study is that the study is possible and that a reasonable proportion of pediatric OHCA can be analyzed from EMS medical reports. Expected outcome: Variables included in the study: age, gender, initial rhythm, etiology of cardiac arrest, event location, observation of occurrence, cardio-pulmonary-resuscitation (CPR), defibrillation and use automatic external defibrillators (AEDs), EMS-response time, hospitalization, return-of-spontaneous-circulation (ROSC), state at hospital admission, 30-day survival, airway management and use of epinephrine.
