Active clinical trials for "Heart Arrest"

Cardiac arrest is handled by cardiopulmonary resuscitation which is a time critical emergency situation. The actions during resuscitation are lead by international guidelines. Traditionally, the main focus of the training has been on medical knowledge and technical skills (TS). Nowadays non-technical skills (NTS), such as communication, teamwork behaviour, and leadership, are considered at least equally important. The aim of this study is to evaluate both TS and NTS of the resuscitation team during real-life resuscitation situations using a validated assessment tool. The association between TS and NTS will be analyzed. Findings from this study may help to recognize the possible weaknesses and issues which could be improved by training. Hypothesis is that that TS are probably in a high level, but some improvement points of NTS are ought to be known better. Investigators hypothesis that the good NTS performance in resuscitation is accompanied by good TS performance.

The aim of this prospective, explorative study of noninvasive neuromonitoring was to search potential and practical methods associated with neurological outcome in the perioperative and immediate postoperative setting of surgery of the thoracic aorta. These methods include abbreviated EEG monitoring, near-infrared spectroscopy, transcranial Doppler ultrasound and biochemical markers associated with neuronal damage.

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.

The aim of the study is to determine surrogate markers for prognostication of unfavorable outcome (death or persistent vegetative state) in cardiopulmonary arrest survivors. These patients are comatose. Conscious patients are unsuitable for prognostication.

Transient renal insufficiency is frequently observed in the course of cardiovascular arrest. Although elevation of creatinine is reversible in a large majority of cases, severe renal insufficiency is sometimes observed and is associated with a dark prognosis. Any intervention that may limit the worsening of renal function may have an impact on patient mortality. There is currently no validated pharmacological treatment to limit the progression of ARI or to accelerate its recovery. A major challenge then concerns the detection of the reversible character of renal damage. Renal biomarkers have been little studied in the prediction of severe ARI and mortality after cardiac arrest. The combination of TIMP2 (tissue inhibitor of metalloproteinase) and insulin-like growth factor binding protein (IGFBP7) in urine showed good diagnostic performance in the early detection of the risk of developing acute renal failure within 12 hours. Measured in the urine, the excretion of these two markers specifically reflects renal tubular lesions. Moreover, their rate seems to be strongly correlated with the severity of the tubular lesions. Thus, it can be reasonably assumed that their very early dosing in post-cardiac arrest could detect the presence and severity of renal tubular lesions. A threshold to be defined would discriminate patients at risk of developing an ARI within 48 hours post ACR and to distinguish between severe transient and severe persistent lesions beyond 72 hours.

The overall goal of this study is to better understand the factors leading to successful dispatch-assisted CPR instructions and to ultimately save the lives of more cardiac arrest patients. Specific objectives are to: 1) Determine the ability of 9-1-1 dispatchers to make the diagnosis of cardiac arrest over the phone; 2) Quantify the frequency and impact of perceived agonal breathing on cardiac arrest diagnosis; 3) Measure the frequency with which dispatch-assisted CPR instructions can be successfully completed in out-of-hospital cardiac arrest cases; and 4) Measure the impact of dispatch-assisted CPR instructions on bystander CPR and survival rates for out-of-hospital cardiac arrest.

The aim of this study is to gain insight in patients' experiences regarding do not resuscitate conversations and decisions. A multicentre flash mob investigation will be conducted in which data will be obtained over the course of two weeks using electronic questionnaires that patients will fill out. General demographic data and a brief quality of life assessment (EQ-5D) will be collected. Whether a DNR converstation has taken place will be noted, along with patients' experiences with this conversation. Lastly the patient will be asked about his/her expectations of survival after cardiopulmonary resuscitation.

In this study, the investigators compared mechanical and manual chest compressions in out-of-hospital cardiac arrest cases.

A cardiac arrest is often preceeded by a varying period of physiological deterioration which if acted upon may prevent the cardiac arrest. We aim to review patients presenting to the ambulance service with cardiac arrest so see if they had contacted the ambulance service in the preceeding 48 hrs to understand if warning symptoms were missed or not acted upon appropriately.

The study will have an observational retrospective cross-sectional design. Patient records and hospital administrative systems at 10 hospitals in Sweden will be searched using ICD-codes to find all patients treated for an in-hospital cardiac arrest (IHCA) during the time period of 20180101 to 20191231. All found patients will be cross-checked against reported patients in the Swedish Registry of Cardiopulmonary Resuscitation (SRCR). Any differences in patient characteristics or regarding situation factors between reported and non-reported patients will be evaluated. Non-reported patients will be retrospectively reported to the registry. An incidence of IHCA will be calculated using the number of patients treated for IHCA divided by number of hospital admissions during the specific time period. Selected variables will be evaluated regarding compliance to report and regarding concordance with patient records. All missing data will be described and evaluated. Local reporting procedures at each hospital will be described and evaluated regarding compliance to report and regarding missing data.
