Formation par la simulation : étude-pilote sur l’accueil des parents par une équipe de réanimation pédiatrique

Abstract: Resume Contexte Les formations par la simulation sont progressivement integrees dans les cursus de formation des soignants en reanimation. Il existe peu de formations a la communication avec les familles. But Cette etude-pilote a evalue l’impact d’une formation incluant un protocole d’accueil des parents d’un enfant admis en reanimation pediatrique (PAPER) sur les pratiques professionnelles. Materiels et methodes La formation durait 3 mois et comprenait 3 parties : des apports theoriques, une seance de simulation et un focus group . Lors de la session de simulation, une equipe pluri-professionnelle de 3 soignants (medecin, infirmiere, aide-soignante) devait appliquer un PAPER compose de 3 sequences : accueil et habillage par l’aide-soignante, entretien medical en binome medecin/infirmiere, accompagnement dans la chambre en binome infirmiere/aide-soignante. L’enfant etait simule par un mannequin (SimBaby™, Laerdal) et les parents par des acteurs. L’objectif principal de cette etude-pilote etait de mesurer le taux de changement des pratiques professionnelles un an apres la fin de la formation. Resultats Un an plus tard, tous les soignants ( n = 15) reconnaissaient avoir change leurs pratiques professionnelles et estimaient que ces changements etaient attribuables pour moitie a la formation suivie. De nouvelles pratiques comme l’accueil en binome dans une salle dediee ou une courte entrevue avec les parents avant de prendre en charge l’enfant etaient appliquees « toujours » ou « si possible ». Conclusion Cette etude-pilote a montre que la formation avait permis de modifier a un an la moitie des pratiques professionnelles d’accueil des parents d’un enfant admis en reanimation pediatrique.

Relevance of volatile metabolome in animal-derived products to reveal a food chain contamination by hexabromocyclododecane

Abstract: The flame retardant Hexabromocyclododecane (HBCD) is part of the critical emerging contaminants. The diet is the major route of human exposure to HBCD and consumers may be exposed through a single food intake at very high doses. The only way to guarantee their food safety given the unpredictable isolated cases of high contamination is to propose frequent and large-scale controls, yet the current reference analytical methods are economically inconceivable. Alternative approaches based on targeted quantification of livestock's exposure markers to pollutants are proposed. Among the compounds assumed as potential markers, the volatile organic compounds (VOCs) are particularly promising. Based on animal test involving laying hens contaminated or not by HBCD through their feed, the present study demonstrates the relevance of using solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) for profiling VOCs in animal-derived products and for determining the markers of HBCD exposure. The volatile fingerprints of egg yolk and liver allowed the different animal groups to be clearly discriminated and volatile markers of HBCD exposure to be pointed out. The analysis of these markers could enable to reveal systematically suspect samples on market and to guide further analyses to confirm and possibly explain the contamination.

Radiation and circuit model of a planar resonator element with shorting via

Abstract: We propose the study of a planar quasi-lumped resonator element. It is composed of a shorting via, modelled as a parallel inductance and a very short open-ended microstrip line, modelled as a capacitance. We discuss the physical parameter influences of the resonator, which offer a path to control its radiation characteristic. A circuit model with closed-form expressions of the radiation resistance and the unloaded quality factor is presented. The discontinuity influences of the shorting via and the open-ended microstrip borders are discussed. The experimental and theoretical results verify the proposed circuit model. A radiation model based on the results of electromagnetic simulations has also been proposed.

Étude de la reproductibilité du procédé de stérilisation et proposition d’un protocole de requalification des stérilisateurs

Abstract: Unlike EN 554, and since the publication of ISO 17665-1 standard, the user of autoclaves may use methods other than those indicated in the guidelines. Outsourcing the requalification of sterilizers by an external service provider and after observing from the previous requalification reports that the thermometric data seemed reproducible, we decided to propose and validate a validation method for the reproducibility of the sterilization process. This is to exempt from the study of the repeatability of the EN 554 standard in future requalifications. Reproducibility was studied with the sensors of the sterilization service and from the production cycles. This study was carried out in three parts. First, we checked whether our sensors were reliable. Then we evaluated the sterilization process fidelity of each sterilizer. Finally, we compared our measurements performed by the service sensors with the measurements performed by the service provider during the requalifications of the previous years. This work leads us to describe a new protocol of requalification of our sterilizers.
