Filter by: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.
The aim of this field report is to describe as the use ultrasound guidance can facilitate the insertion of intraosseous access, during the resuscitation, in the victims of out-of hospital traumatic cardiac arrest
PROPEA3 is a prospective observational study investigating the recovery of propofol-induced EEG slow-wave activity and its association with neurological outcome after cardiac arrest.
Define the frequency and survival pattern of cardiac arrests in relation to the hospital day of event and etiology of arrest.
Manufacturer's diagrams showing defibrillation pad positioning (as used on public access defibrillators) are anatomically incorrect and are likely to lead to poor position of defibrillation pads, with reduced defibrillation efficacy. We will ask untrained members of the public to observe the diagrams and place pads as indicated on the diagram. We will asses the accuracy of pad placement and repeat the study using an anatomically correct diagram to see if we can improve the accuracy of pad placement.
This is a randomized, double-blind, placebo controlled study to investigate the effect of intravenous thiamine (vitamin B1) on lactate, cellular oxygen consumption, global oxygen consumption and biomarkers of neurologic injury after out-of-hospital cardiac arrest (OHCA). .
Approx. 65% of resuscitated patients at the intensive care unit for internal medicine are due to myocardial infarction. Almost all patients are initially diagnosed and treated in the cath lab. Therapy usually consists of one or more stent implantations. After implantation of a coronary stent, dual platelet inhibition is necessary for 12 months. Insufficient platelet inhibition causes an pronounced increase in risk of stent thrombosis. Therefore, secured inhibition and knowledge of the individual platelet function is valuable.
Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.
This will be a prospective observational study of adult primary cardiac arrest patients presenting to Shands Emergency Department following ROSC or actively in cardiac arrest with subsequent ROSC after treatment in the emergency department.
French guidelines for Cardio Pulmonary Resuscitation (CPR) consider Extra-Corporeal Life Support (ECLS) as one option in Refractory out-of hospital Cardiac Arrest (ROHCA) patients with a no-flow less than five minutes and absence of spontaneous circulation 30 minutes after initiation of advanced CPR. Duration of both pre-CPR arrest (no-flow) and of CPR (low-flow) have been systematically highlighted as crucial prognostic factors in all observational studies focused on ROHCA. In order to shorten the time to ECLS initiation, the most recent European Resuscitation Council guidelines recommend, in eligible ROHCA patients, a fast track access to ECLS implantation. CHRU Nancy elaborated an operational strategy which was designed to improve the enrolment of eligible ROHCA patients and to reduce the delay time between recognition and ECLS initiation. The objective of the present register was to assess prospectively the impact of this new operational strategy over a 5 years period.
