Chirurgie ambulatoire de la cataracte sous anesthésie topique sans anesthésiste : comment simplifier les procédures sans iatrogénie ? by Quentin Duroi( )

2 editions published in 2020 in French and held by 3 WorldCat member libraries worldwide

Introduction: The Ambulatory Cataract Surgery Center (CACC) of the Bourges Hospital provides a fast-track procedure for cataract surgery under topical anesthesia without preoperative anesthetic evaluation or intraoperative anesthesia care. This study aims to evaluate the safety of this procedure and to assess the patient's satisfaction. Materials and methods: This is a prospective single center study including all the patients who underwent cataract surgery in the CACC between May and August 2018. Each patient was selected by the ophthalmologist during the preoperative evaluation. Interventions were performed under topical anesthesia without the presence of a nurse anesthetist nor anesthesiologist, the patient had not fasted, and no peripheral venous line was placed. Blood pressure was measured before intervention and oxygen saturation was monitored intraoperatively with pulse oximetry. In case of emergency, the hospital's medical emergency teamwas available to intervene. Incidence and nature of intraoperative adverse events and surgical complications were recorded. Patient satisfaction was scored using the Iowa Satisfaction with Anesthesia Scale (ISAS). Results: 651 cataract surgeries were performed in 500 patients. 614 surgeries were uneventful (94.3%). 30 intraoperative adverse events (4.6%) and 8 surgical complications were recorded (1.2%). All surgeries were successfully completed. No medical emergency team intervention was necessary. No hospital admittance was required in any case. Mean ISAS score was 5.7/6, indicating high patient satisfaction. Conclusion: Cataract surgery can be safely performed in our ambulatory center with high patient satisfaction, without the direct availability of anesthesia monitoring or care. Patients need to be selected during preoperative ophthalmic consultation but most of them can safely undergo surgery without the intervention of an anesthesiologist
Evaluation de la pertinence des transferts aux services d'urgences des personnes résidant en établissement d'hébergement pour personnes âgées dépendantes by Simon Thummel( )

Background: France is experiencing a steady increase in the number of residents living in nursing homes (NHs). Each year, 50% of these residents are hospitalized. Half of them in emergency department (ED). A part of these transfers to EDs are unjustified and not without consequences. The first aim of our study is to evaluate the proportion of inappropriate NH residents' transfers to EDs. Methods/design: An observational, prospective, cross-sectional and multicentric study was conducted between January and August 2019 in the 6 EDs of Indre-et-Loire county during 3 inclusion periods. A multidisciplinary expert panel determined the inappropriateness of each transfer to EDs. The results are expressed in gross values and in %. Expert agreement is assessed by Fleiss' kappa statistical measure. Results: 836 patients were included. Transfers were deemed inappropriate in 12 to 35% of cases and appropriate in 53 to 81% of cases according to the experts. Fleiss' Kappa score on the concordance of the different experts' answers concerning the relevance of transfers is slight with k = 0.28 with a significant p-value (p<0.0001). Conclusions: Too many transfers of NH residents to EDs remain inappropriate. There is a disparity of results among the experts reflecting a limitation of our study related to the subjective nature of relevance. In a society where demographic projections predict a continuing aging population and where EDs are regularly saturated, it would be interesting to identify and prevent factors predisposing to ED transfers and to consider a geriatric emergency pathway
Evaluation de la prise en charge médicalisée des anaphylaxies en préhospitalier par le SAMU 37 au jour des recommandations de la SFMU de 2016 : étude observationnelle rétrospective multicentrique sur 2 ans by Maxime Gobillard( )

The aim of this study was to assess if the medicalized management of anaphylaxis by the EMS of Indre-et-Loire (France), was consistent with the 2016 French Society for Emercency Medecine guidelines, and to identify clinical factors specific to serious patients not managed according to these guidelines. This retrospective descriptive multicentric observational study conducted in the Indre-et-Loire department (France) included all adults treated in 2018 and 2019 by the EMS of Indre-et-Loire's medicalized prehospital teams and presenting anaphylaxis. The initial characteristics of the patients and their treatment were compared by distinguishing between non-serious and serious allergies, and then, for the serious allergies group, by comparing the treatment that complied and that did not comply with the guidelines. This study included 78 patients, 57.6% of whom had serious allergies. Patients with severe allergy had more cardiovascular risk factors (p<0.01), non-asthmatic respiratory history (p<0.05), respiratory (p<0.01), digestive (p<0.05) and hemodynamic (p<0.001) signs than patients with non-serious allergy. Treatments prior to the arrival of EMS teams did not differ according to the severity of the allergy. Epinephrine was administered by EMS in 24.4% of patients included. Only 31.1% (n=14) of severe allergies received intramuscular epinephrine. Clinically, no difference was found between serious patients managed according to guidelines and those who did not, except for respiratory and hemodynamic signs (p<0.05). This study highlights a lack of adherence to guidelines in the pre-hospital management of anaphylaxis, with insufficient use of epinephrine for severe patients
Estimation du débit de filtration glomérulaire à la phase aiguë de l'état de choc : place des formules dynamiques by Maxime Desgrouas( )

2 editions published in 2020 in French and held by 3 WorldCat member libraries worldwide

Introduction. Les formules statiques d'estimation du débit de filtration glomérulaire (DFG) ne sont pas utilisables chez les patients de réanimation. La place des formules dynamiques, qui prennent en compte le temps écoulé entre deux mesures de créatinine, est à évaluer. Notre objectif était de déterminer la formule dynamique ayant le plus faible biais par rapport à la clairance du iohexol chez les patients de réanimation en état de choc. Matériels et Méthodes. Il s'agit d'une analyse ancillaire de l'étude multicentrique Ioxrea, comparant à la 24e heure l'estimation du DFG par les formules dynamiques à la clairance du iohexol, avec ou sans correction de la créatinine selon le volume de distribution et le poids idéal théorique, chez des patients en insuffisance circulatoire. Résultats. Nous avons évalué 3 formules statiques (Cockroft et Gault, MDRD, CKD-EPI), la clairance urinaire de la créatinine et 8 formules dynamiques (Jelliffe, Bouchard, Chen, Chiou et Hsu, Moran et Myers, Yashiro, Seelhamer, Brater). Trente-neuf versions de ces différentes formules après application des facteurs correctifs ont été testées chez 57 patients. La formule de Moran et Myers corrigée par le volume de distribution et le poids idéal théorique présentait la meilleure précision à 19,6 mL/min/1,73m2, un coefficient de corrélation à 0,69, un biais moyen de 11,6 mL/min/1,73m2 (limites d'agrément : -49,6 ; 72,7). Discussion. Les formules dynamiques d'estimation du DFG peuvent sous-estimer ou surestimer le DFG de manière importante. La correction de la créatininémie et du volume de distribution ne sont pas suffisants pour rendre ces formules fiables. Conclusion. On ne peut pas évaluer le DFG des patients en état de choc par des formules dynamiques
Etude de facteurs physiques et physiologiques influant sur la cinétique des aérosols médicamenteux by Pierre François Dequin( Book )

Nous avons étudié les paramètres permettant d'optimiser la nébulisation dans deux modèles : la mucoviscidose et la ventilation mécanique. Nous avons tout d'abord montré que le marquage isotopique d'un aérosol d'amikacine ne modifiait pas son comportement physique et permettait donc d'étudier son devenir dans l'organisme. In vivo, nous avons montré que la masse déposée dans le poumon était corrélée à la fraction inhalée et tendait à être inversement corrélée à la concentration en P. aeruginosa dans les sécrétions bronchiques, puis que la masse éliminée dans les urines était effectivement corrélée à celle déposée dans le poumon, ce qui suggère la possibilité d'évaluer de façon non invasive et non irradiante la masse d'aminoglycoside déposée dans le poumon par nébulisation. En modélisant in vitro des conditions de ventilation mécanique, nous avons montré que la rentabilité de la nébulisation de fénotérol était moins bonne que celle de l'administration par aérosol-doseur, suggérant un effet plateau dans la courbe dose-réponse au fénotérol en ventilation mécanique, l'effet global mesuré par ailleurs sur les résistances totales du système respiratoire étant d'amplitude comparable. Nous avons ensuite comparé, à FiO2 et volume courant identiques, l'influence d'un mélange air-oxygène et hélium-oxygène sur les caractéristiques d'un aérosol de salbutamol généré par deux nébuliseurs pneumatiques de type différent. Nous avons montré que la masse inhalable était influencée significativement par le type de nébuliseur, par la durée d'ouverture du système de nébulisation et, de façon plus marginale, par le type de gaz, l'hélium augmentant effectivement la masse inhalable avec le moins performant des nébuliseurs et pour un temps d'ouverture plus long. Le choix du nébuliseur s'est donc avéré dans ce modèle plus important que le gaz utilisé pour la ventilation
