Active clinical trials for "Post-Cardiac Arrest Syndrome"

Post-cardiac arrest mortality remains high and proper care after cardiopulmonary resuscitation is an important clinical challenge. This prospective observational cohort aims to (1) identify the factors that affect short-term and long-term survival in post-cardiac arrest survivors and (2) investigate the patients and their families' health-related quality of life and psychological well-being.

Only half of the patients suffering from cardiac arrest arrive at the hospital alive. Of these survivors, more than 50% will still die or remain severely disabled. During cardiac arrest ischemia causes damage to the vital organs, especially the brain. When with return of spontaneous circulation oxygen is re-offered to the ischemic organs, massive amounts of reactive oxygen species (ROS) are produced. These ROS can further increase the damage to the myocardium and brain (reperfusion injury). Vitamin C is the primary circulating antioxidant. It scavenges free radicals and reduces the production of ROS. In a recent study we demonstrated that vitamin C plasma levels are deficient in ~60% of the patients after cardiac arrest, probably due to massive consumption. Vitamin C deficiency reduces the protection against oxidative stress. Intravenous supplementation is needed to restore deficiency and the antioxidative effect of vitamin C is much more potent if it is administered in a supraphysiological dose (≥ 3 g per day). Its strong antioxidative effect may reduce damage to the circulation and to brain, heart and other organs. Beneficial effects of high dose i.v. vitamin C after cardiac arrest have been demonstrated in preclinical studies, but not in patients. The investigators hypothesize that vitamin C can reduce organ damage, especially cerebral injury, if administered for a short period as a high i.v. dose during the very early phase of reperfusion after cardiac arrest. Objectives: To determine whether an early high dose i.v. vitamin C can improve organ function, especially neurological outcome, in patients after cardiac arrest To explore the optimal dosing regimen for high dose i.v. vitamin C To investigate in vitro the difference in effect of plasma obtained from post cardiac arrest patients treated with placebo, 3 gr/day or 10 gr/day vitamin C on endothelial cell viability and underlying oxidative pathways.

XePOHCAS: Prospective, randomized, multicenter interventional trial in adult subjects with out-of-hospital cardiac arrest comparing treatment with standard-of-care post-cardiac arrest intensive care (which is targeted temperature management [TTM]) to xenon by inhalation plus standard-of-care post-cardiac arrest intensive care (including TTM).

The prevalence of cardiac arrests is still high worldwide. Despite the return of spontaneous circulation (ROSC), mortality and morbidity in post cardiac arrest patients is reported high. Comprehensive management is essential in treating patients with post cardiac arrest syndrome. Adequate circulatory stability is achieved with fluid therapy, vasoactive drug therapy, and consideration of mechanical support. Intra-Aortic Ballon Pump (IABP) is one of the most feasible and available mechanical support in developing countries including Indonesia. There are several benefits of IABP reported in acute myocardial infarction complicated with cardiogenic shock. Nevertheless, the IABP-SHOCK II study revealed contradictive result which is IABP support was not improving mortality in acute myocardial infarction complicated with cardiogenic shock after revascularization. Other study, Korean Acute Myocardial Infarction Registry (KAMIR), also reported no benefits of IABP support in cardiogenic shock patients. But, the study the investigators mentioned earlier is a registry study, attributed to selection bias and several confounding factors resulting mismatch in population. There are no consideration to IABP time of initiation and duration of use in both studies. The Investigator is aiming to prove the early insertion of IABP to a better outcome compared with the absence of early IABP. The objective of the study is to assess mortality in post cardiac arrest syndrome patients with early insertion of IABP support. A total of 102 subjects will be enrolled in this study, divided into IABP and non-IABP group. The primary outcome is in-hopital-mortality, and various indicators in the pathomechanisme of post cardiac arrest syndrome will be measured in 30 minutes and 6 hours after ROSC. Effective lactate clearance, IL-6, Beclin-1, Caspase-3, a-vO2 diff, and ScvO2, cardiac output, VTI, TAPSE and ejection fraction will be measured and analized between the two groups.

Cardiac arrest is a leading cause of sudden death, but the survival rate of cardiac arrest is only 5-35%. Although, the first resuscitation of cardiac arrest patient would be success, the hypoxic brain injury after cardiac arrest is an important cause of the mortality and the morbidity. For the management of the hypoxic brain injury after cardiac arrest, American Heart Association and European Resuscitation Council recommend induced mild hypothermia therapy. And, ILCOR(International Liaison Committee on Resuscitation) announced the standard treatment of post cardiac arrest syndrome(the success state of first resuscitation of the cardiac arrest patient) included the induced mild hypothermia therapy at September, 2008. The generalized seizure and myoclonus arise in over 60% of post cardiac arrest syndrome patients and they are very difficult to control. Also, the occurrence of them implies poor prognosis of the patient. Although, mild hypothermia therapy could be decrease the development and propagation of generalized seizure and myoclonus theologically, the therapy could not prevent the development and propagation of them entirely. Therefore, the use of prophylactic anticonvulsant should be needed. But, there is not randomized control study about the use of prophylactic anticonvulsant. We hypothesized that the use of prophylactic anticonvulsant to post cardiac arrest syndrome patients would decrease the rate of occurrence of generalized seizure and myoclonus and would improve the neurologic outcome. We planed that we used two anti-epileptic drugs - valproate, clonazepam - for the prophylactic anticonvulsant. The valproate and clonazepam are in general use for prevention and treatment of generalized seizure and myoclonus and are recommended to treat of generalized seizure and myoclonus to post cardiac arrest syndrome patients by 2008 guideline of ILCOR.

To evaluate the significance of free-plasma deoxyribonucleic acid (DNA) and plasma histones in cardiac arrest patients.

This study includes comatose survivors of out-of-hospital cardiac arrest treated with 24 hours or 48 hours of targeted temperature management. The overall aim is to evaluate the importance of plasma complement protein concentrations in patients resuscitated after out-of-hospital cardiac arrest and treated with 24 hours or 48 hours of targeted temperature management. The specific aim is to evaluate: the concentration of plasma lectin pathway proteins the first, second and third day after cardiac arrest the relation between concentration of plasma lectin pathway proteins and mortality if prolonged targeted temperature management influences the concentration of plasma lectin pathway proteins This study is a sub-study to the trial entitled: "Time-differentiated targeted temperature management (TTH48) (ClinicalTrials.gov Identifier: NCT01689077)" The following Complement Lectin Pathway proteins will be measured: Mannan-Binding-Lectin, M-ficolin, H-ficolin, CL-L1, MASP-1, MASP-2, MASP-3, MAp19 and MAp44.

Rational: Out of hospital cardiac arrest is a devastating event with a high mortality. Survival rates have increased over the last years, with the availability of AED's and public BLS. Previous studies have shown that deranged physiology after return of spontaneous circulation (ROSC) is associated with a worse neurological outcome. Good quality post-arrest care is therefore of utmost importance. Objective: To determine how often prehospital crews (with their given skills set) encounter problems meeting optimal post-ROSC targets in patients suffering from OHCA, and to investigate if this can be predicted based on patient-, provider- or treatment factors. Study design: Prospective cohort study of all patients attended by the EMS services with an OHCA who regain ROSC and are transported to a single university hospital, in order to identify those patients with a ROSC after a non-traumatic OHCA who had deranged physiology and/or complications from OHCA EMS personnel was unable to prevent/deal with in the prehospital environment. Study population: Patients, >18 years, transported by the EMS services to the ED of the University Hospital Groningen (UMCG) with a ROSC after OHCA in a 1 year period Main study parameters/endpoints: Primary endpoint of our study is the percentage of OHCA patients with a prehospital ROSC who arrive in hospital with either a deranged physiology or with complications from OHCA EMS personnel was unable to deal with.
