Active clinical trials for "Heart Arrest"

Extracorporeal membrane oxygenation (ECMO) is a lifesaving procedure used to treat severe forms of heart and/or lung failure. It works by the principal of replacing the function of these organs by taking blood from the patient, provide it with oxygen outside the body and return it to the patient in one continuous circuit. Because of the evaluability of better technology, the use of ECMO has exponentially risen over the last decade. This treatment is very invasive and carries a number of risks. It is mostly used in situations where it seems likely that the patient would otherwise die and no other less invasive measure could change this. Still in large registries 50-60% of patients die which is often due to complications associated with the treatment. One of the most important complication is caused by the activation of clotting factors during the contact with the artificial surfaces of the device. This can lead to clot formation inside the patient or the device. To counterbalance this anticoagulation is needed. Because of the consumption of clotting factors and the heparin therapy bleeding complications are also very common in ECMO. Clinicians are challenged to balance these competing risks and are often forced to transfuse blood products to treat these conditions, which comes with additional risks for the patient. Many experienced centres have reported thromboembolic and bleeding events as the most important contributor to a poor outcome of this procedure. However, no international study combining the experience of multiple centres to compare their practice and identify risk factors which can be altered to reduce these risks. This study has been endorsed by the international ECMONet and aims to observe the practice in up to 50 centres and 500 patients worldwide to generate the largest ever published database on this topic. It will concentrate on patients with severe heart failure and will be able to identify specific risk factors for thromboembolic and bleeding events. Some of these factors may be modifiable by change in practice and can subsequently be evaluated in clinical trials. Some of these factors may include target values for heparin therapy and infusion of clotting factors. This study will directly improve patient management by informing clinicians which measures are associated with the best outcome and indirectly helps building trials to increase the evidence further.

This submission is a pilot in which the new IQool Warming System device will be used to maintain the temperature of adult patients in cardiac arrest within a range of within a range of 32°C to 38.5°C (89.6°F to 101.3°F). The IQool Warming System has received a 510 K Clearance by the FDA.

The study is a retrospective analysis of Taiwan national health insurance in cardiac arrest patients. The factors related to the outcomes of cardiac arrest patients were analyzed.

Several studies show how patients with hyperoxia after cardiac arrest has increased mortality, but the association of hyperoxia before cardiac arrest and myocardial damage has never been investigated. Neither has the association between hyperoxia after cardiac arrest and myocardial injury. Our research hypothesis is that hyperoxia before cardiac arrest aggravates myocardial damage, secondly we wish to analyze the association between hyperoxia after cardiac arrest and myocardial injury. The exposure variables is oxygenation within 48 hours before and 48 hours after cardiac arrest, our primary outcome is myocardial damage and will be measured as peak troponin within 30 days after cardiac arrest.

The Resuscitation Outcomes in the Netherlands - study assesses one-year survival and quality of life after In-Hospital Cardiac Arrest(IHCA). It's design is a multicenter prospective observational cohort study which will include all patients undergoing cardiopulmonary resuscitation (CPR) for IHCA in 2017. Current literature describes poor survival after IHCA and no risk stratification tool for long-term outcome is available. Furthermore no such study has ever been performed in the Netherlands. The investigators aim to gain further insight in this major adverse event.

The aim of the study is to describe CBF modifications during rewarming after targeted temperature management in cardiac arrest patients

Theoretical knowledge of cardiopulmonary resuscitation (CPR) is the foundation of being able to perform CPR in a cardiac arrest situation. The knowledge and skills received in training is easily lost and after one year the level is equal to pretraining. International studies regarding knowledge of CPR among healthcare professionals, mostly nurses, show poor results. The knowledge of CPR among Swedish healthcare professionals is poorly studied. The aim of this study was to describe the theoretical knowledge of CPR and self-assessed abilities of performing CPR among healthcare professionals working in four hospitals in Sweden.

Hypoxic-Ischemic-encephalopathy (HIE) is a severe and frequent neurological complication of successful cardiopulmonary-resuscitation after cardiac arrest (CA). Prognosticating neurological outcomes in patients with HIE is challenging and recent guidelines suggest a multimodal approach. Only few studies have analyzed the prognostic power of the association between instrumental tests and, in addition, most of them were monocentric, retrospective and evaluating only poor outcome.

The fight against the scarcity of grafts is a major public health issue in France. Despite a very good success rate of transplants from brain-dead donors or living donors, the waiting time for transplantation continues to increase, leading to morbidity and mortality, as well as medical costs. Since 2005, the BioMedicine Agency has implemented a protocol authorizing kidney and liver samples taken from deceased donors after cardiac arrest (DDAC). This type of sampling has become a common practice in several regions of France and Europe. In case of DDAC, the sampling protocol poses a significant temporal constraint, since the patient must be taken within 6 hours after the cardiac arrest. This constraint leads to a specific organization of the announcement of the death and the request for non-opposition to the levy. The brutal loss of a loved one is a potentially traumatic experience for family members. The manifestations of the pathological components of mourning such as post-traumatic stress disorder, anxio-depressive syndrome, pathological bereavement, are often expressed early in the first year after the death of the loved one. Families of organ donor patients probably represent a population at high risk for the expression of psychiatric conditions such as post-traumatic stress disorder or pathological bereavement. The limited time available to prepare relatives to make a decision could promote the expression of psychiatric morbidity in the short or medium term. The data on this new transplantation procedure and its psychological consequences are insufficient, and we consider that if a state of post-traumatic stress occurred in more than 50% of parents, the procedure of announcement would be reviewed. The purpose of this study is to test this hypothesis. Most of the work on relatives of potential organ donors has focused on procedures for brain death. Most of this work has focused on characterizing the determinants of acceptance or refusal of organ donation in the family. The literature relating to the follow-up of relatives of a patient after organ donation is very poor: very few studies have focused on the psychological consequences and / or the psychological state of this population in the period post-death. In addition, very few qualitative and quantitative studies make it possible to evaluate the appearance of psychopathological manifestations related to the announcement of death simultaneously with a request for organ removal. This research, therefore, will make it possible to estimate the possible psychological impact on the bereaved family as well as an assessment of the psychological state. A mixed methodology (quantitative and qualitative) will make it possible to highlight explanatory factors of the quantitative results.

The aim of this study is to evaluate the prognostic value of the suppression ratio monitored by Bispectral Index for prediction of neurologic outcome after cardiac arrest. All patient admitted to our intensive care unit after a cardiac arrest are included. The results of the suppression ratio will be collected in the 6 first hours of admission. We will evaluate the link between suppression ratio and cerebral performance category score collected at three months.
