    National audienceIntroduction Le dĂ©pĂŽt de sang du dĂ©chocage du CHU de Rennes est un dĂ©pĂŽt d’urgence oĂč seule l’urgence vitale justifie l’utilisation des produits sanguins labiles (PSL) stockĂ©s. L’objectif de cette Ă©valuation des pratiques professionnelles Ă©tait de caractĂ©riser les PSL dĂ©livrĂ©s par ce dĂ©pĂŽt en 2013 ainsi que la population transfusĂ©e. La pertinence d’utilisation de ces PSL a Ă©galement Ă©tĂ© analysĂ©e. Patients et mĂ©thode Deux groupes d’experts, cliniciens et hĂ©movigilant, ont Ă©valuĂ© la pertinence d’utilisation des PSL du dĂ©pĂŽt Ă  partir de critĂšres cliniques, biologiques et des dĂ©lais de transfusion. RĂ©sultats Cent vingt-deux PSL (112 CGR et 10 PFC) ont Ă©tĂ© transfusĂ©s Ă  49 patients, d’ñge moyen 55 ans, majoritairement de sexe masculin (69 %). Les indications principales Ă©taient le polytraumatisme et l’hĂ©morragie digestive. Lors de la dĂ©cision transfusionnelle, l’Hemocue moyen Ă©tait de 7,7 ± 2,4 g.dL−1 et 85 % des patients prĂ©sentaient des signes de choc (Tableau 1). Le taux de mortalitĂ© (25 %) et le nombre moyen de PSL transfusĂ©s dans les 24 heures (10 CGR, 10 PFC et 2 CP) tĂ©moignaient de la gravitĂ© des patients. Le dĂ©lai moyen entre l’admission du patient et la transfusion du premier PSL du dĂ©pĂŽt Ă©tait de 61 minutes. Pour 62 % des patients, l’hĂ©moglobinĂ©mie post-transfusionnelle Ă©tait > Ă  10 g.dL−1. L’utilisation des PSL Ă©tait pertinente dans 75 % des cas mais le choix du phĂ©notype RhĂ©sus des CGR n’était pertinent que dans 35 % des cas. Conclusion Le nombre important de transfusions par excĂšs nĂ©cessite la mise en place d’un programme d’optimisation de la quantitĂ© de CGR transfusĂ©s par patient. Une sensibilisation des prescripteurs sur la ressource prĂ©cieuse en CGR O RH-1 est nĂ©cessair

    International audienceBackground and Aims: A risk of tracheal mucosa injury induced by subglottic suctioning has been raised. Therefore, this prospective randomized study aims to compare the effect of continuous suctioning of subglottic secretions versus intermittent suctioning of subglottic secretions (CSSS vs. ISSS) secretions on tracheal mucosa in front of the suctioning port of the endotracheal tube.Patients and Methods: Patients requiring intubation or reintubation in Intensive Care Unit with an expected ventilation duration > 24 h were eligible. Participants received CSSS at -20 mmHg or ISSS at -100 mmHg during 15 s and no suction during 8 s. The effect on tracheal mucosa in front of the suction port was assessed after intubation (T0) and before extubation (T1) using bronchoscopy. Tracheal mucosa damages were graded into five categories (no injury, erythema, edema, ulceration, or necrosis). The occurrence (no injury observed at T0 but present at T1) or the worsening (injury observed at T0 exacerbating at T1) was studied.Results: Seventy-three patients were included and 53 patients (CSSS, n = 26 and ISSS, n = 27) were evaluable on the primary endpoint. The occurrence or worsening of tracheal mucosal damages did not differ between the two groups (CSSS, n = 7 [27%] vs. ISSS, n = 5 [17%], P = 0.465). Daily average volume of suctioned secretion was higher with ISSS (74 ± 100 ml vs. 20 ± 25 ml, P < 0.001). Impossibility to aspirate was higher with CSSS (0.14 ± 0.16 per day vs. 0.03 ± 0.07 per day, P < 0.001).Conclusions: Our results suggest that tracheal mucosal damages did not differ between CSSS and ISSS. The aspirated volume was higher and impossibility to aspirate was lower with ISSS.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT01555229
