Cardiac arrest is at present a major cause of mortality as well as a cause of disability for the surviving victims.In Europe, every year counts as 300,000 cardiac arrests responsible for 250,000 deaths. Thus, less than 20 % of patients discharged home with impaired quality of life associated with symptoms of tiredness, stress, anxiety. The prognosis is related to the initial cardiac rhythm present during the initiation of resuscitation. Recent progress in the improvement of mortality and neurological outcome has been achieved over the last decade thanks to the systematic implementation of a period of targeted temperature control between 32 and 34 ° C in patients who benefited from the realization of at least one electrical external shock. There are theoretical and clinical arguments to think that achieving the same way a period of targeted temperature control between 32 and 34 ° C in patients treated for cardiac arrest with a non- shockable rhythm on arrival can also benefit from this procedure. However other arguments are against this hypothesis including an increase in the risk of infection , worsening of the patient's hemodynamic status with no benefit to him. To answer this question, we conduce a randomized multicenter study testing the potential improvement of neurological outcome through this procedure targeted temperature control between 32.5 and 33.5 ° C in these patients.
Cardiac arrest during pregnancy is rare but may result in poor maternal and fetal outcome. Because of its rare occurrence and ethical issues this topic is not very well studied and many questions pertaining to maternal resuscitation remain unanswered. One of the challenging aspects of cardiopulmonary resuscitation in a term pregnant patient is the ideal positioning during chest compressions. International societies have made recommendations regarding management of pregnant patients during cardiac arrest. They advocate the use of left lateral position with 30 degrees tilt or manual uterine displacement. However these recommendations are not based on high level of evidence. Ultrasound has been used to visualize the change in diameter of great vessels to determine the volume status or adequacy of blood circulation of these patients. This approach can be used to study the adequacy of blood circulation of pregnant patients in different positions. The objective of this study is to compare the change in Inferior vena cava diameter obtained with pregnant women in either the left lateral tilt or in the supine position with a manual uterine displacement, compared to the left lateral position and the supine position. Our hypothesis is that the inferior vena cava diameter obtained in the supine position with manual left uterine displacement would be larger as compared to that obtained with women positioned with a 30-degree tilt.
Determination of vital and functional outcome in comatose survivors after cardiac arrest is principally based on the identification of predictors of non-awakening, using by clinical, biological and electrophysiological tools. In patients without presence of non-awakening predictors, it would be of interest to identify predictive criteria of awakening. The presence of mismatch negativity during the cortical auditory-evoked potential could contribute to further progress in neurological prognostication of these patients. However, at this time, its prognostic value has been insufficiently studied and the optimal time of realization remains unknown.
This study is to test the use of simulation training to improve 9-1-1 telecommunicators' call processing and response. Training sessions will expose 9-1-1 telecommunicators to several realistic emergency situations through mock 9-1-1 calls with a trained actor playing the part of a reporting party, followed immediately by feedback on call handling provided by a trained call observer. Investigators hypothesize that simulation followed by trained observer-directed feedback will increase correct triage of medical emergency and delivery of pre-arrival instructions during simulated calls and in actual 9-1-1 calls.
The aim of the study is to describe the mechanisms of ultra-acute hyperglycemic response after return of spontaneous circulation (ROSC) in patients suffering out-of-hospital cardiac arrest. The investigators hypothesize that ischemia and reperfusion injury leads decreased secretion of insulin and glucose-like peptide 1 (GLP-1). Two blood samples will be drawn: (1.) Immediately after ROSC and (2.) 60 minutes after first sample. Concentrations of glucose, insulin, glucagon and GLP-1 will be compared between the samples. Metabolic profile will be compared between: (1.) diabetic and non-diabetic patients and (2.) survivors and non-survivors.
Background: Cardiac arrest is a life-threatening event. Intensivists are challenged with an increasing number of patients with uncertain neurological outcome following cardiopulmonary resuscitation (CPR). The prognostic value of current biomarkers for neurophysiologic long-term outcome is limited. Hypothesis: We hypothesize that specific brain-derived tissue leakage proteins can be identified to reveal novel, more reliable prognostic biomarkers for good neurological outcome. Methods: This translational study (n=100) is a combination of a prospective basic science study intended to reduce the number of potential plasma biomarker candidates by proteomic shotgun analyses in brain tissue autopsy samples and plasma samples from resuscitated patients (n=10) and a prospective clinical validation study in a large study population (n=90) by high-throughput analyses. Selection of proteomic markers and signature estimation will be performed to discriminate patients with good and poor outcome. Clinical perspective: A structured proteomic analysis approach might identify the best marker out of all proteins liberated during cellular damage.
