Prise en charge des accidents vasculaires cérébraux au SAU de l'Hôtel-Dieu et à l'UNV de l'Hôpital Nord Laënnec en 2007

Les accidents vasculaires cérébraux sont une urgence diagnostic et thérapeutique. La réduction des délais passe par une meilleure reconnaissance des symptômes mais également par un appel sans délai au 15. L'étude REFLEX'AVC s'est proposée d'évaluer ces délais et les facteurs responsables d'un retard dans la prise en charge. Seulement 25 % des patients sont hospitalisés dans les deux heures trente suivant le début des symptômes. Les facteurs identifiés comme associés à un retard sont : l'installation progressive des symptômes et le recours initial au médecin traitant. La reconnaissance des symptômes de l AVC est insuffisante, les troubles de la parole étant moins souvent identifiés que les déficits moteurs.NANTES-BU Médecine pharmacie (441092101) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF

Noninvasive ventilation use in French out-of-hospital settings : a preliminary national survey

OBJECTIVE: The objective of our study was to describe noninvasive ventilation (NIV) practices (pressure support ventilation and continuous positive airway pressure) in French out-of-hospital mobile intensive care units (SMUR) and their compliance with national consensus guidelines. METHOD: Online inquiry into practices of NIV among managers of French SMUR. Analyzed data include types of NIV devices and use of NIV. RESULTS: Upon 218 SMUR referenced within the SAMU de France database, 118 questionnaires (54%) were processed. Noninvasive ventilation equipment: 91% of the SMUR with at least one type of NIV device (continuous positive airway pressure only = 82%; pressure support ventilation only = 59%; both = 50%) but frequently not with recommended devices. Use of NIV: for acute cardiogenic pulmonary edema, practices were compliant with recommendations in 80% of cases, although there was still room for improvement. For other pathologies, practices were very heterogeneous, not always properly assessed, and frequently not compliant with recommendations. CONCLUSION: To conclude, NIV use in the out-of-hospital setting in France seems to meet current recommendations for acute cardiogenic pulmonary edema but not for other pathologies. This could be improved by the use of written procedures, conduction of further studies, and promotion of compliance through education

HTS insert magnet design study

International audienceFuture accelerator magnets will need to reach higher field in the range of 20 T. This field level is very difficult to reach using only Low Temperature Superconductor materials whereas High Temperature Superconductors (HTS) provide interesting opportunities. High current densities and stress levels are needed to design such magnets. YBCO superconductor indeed carries large current densities under high magnetic field and provides good mechanical properties especially when produced using the IBAD approach. The HFM EUCARD program studies the design and the realization of an HTS insert of 6 T inside a dipole of 13 T at 4.2 K. In the HTS insert, engineering current densities higher than 250 under 19 T are required to fulfill the specifications. The stress level is also very severe. YBCO IBAD tapes theoretically meet these challenges from presented measurements. The insert protection is also a critical because HTS materials show low quench propagation velocities and the coupling with the magnet makes the problem even more challenging. The magnetic and mechanical designs of the HTS insert as well as some protection investigation ways will be presented
