Ne paniquez pas en cas d'\u00e9chec de la st\u00e9rilisation.<br><strong>I. Chargement non conforme<\/strong><br>Un chargement incorrect entrave la circulation de la vapeur. Les articles st\u00e9rilis\u00e9s ne doivent pas \u00eatre trop serr\u00e9s ni trop entass\u00e9s. Lors de leur disposition, veillez \u00e0 les empiler en quinconce, en alternant les rang\u00e9es, afin de laisser des espaces qui facilitent la circulation de la vapeur.<br><strong>Mesures d'am\u00e9lioration :<\/strong><br>St\u00e9rilisez les articles de m\u00eame type dans le m\u00eame autoclave. Lorsque vous st\u00e9rilisez des articles de types diff\u00e9rents dans le m\u00eame autoclave, placez les paquets de pansements sur la couche sup\u00e9rieure et les paquets m\u00e9talliques sur la couche inf\u00e9rieure ;<br>Placez autant que possible les objets susceptibles de produire des gouttelettes d'eau sur la couche inf\u00e9rieure ;<br>Utilisez des paniers de st\u00e9rilisation pr\u00e9vus \u00e0 cet effet pour le chargement, n\u2019empilez pas les articles et veillez \u00e0 laisser un espace d\u2019au moins 2 centim\u00e8tres entre chaque paquet ;<br>Les plateaux d'instruments chirurgicaux doivent \u00eatre pos\u00e9s \u00e0 l'horizontale, les paquets en tissu \u00e0 la verticale et les bassines chirurgicales en biais ;<br>Les articles emball\u00e9s dans du papier ou du plastique doivent \u00eatre plac\u00e9s \u00e0 la verticale dans des paniers ou sur des \u00e9tag\u00e8res.<br><strong>II. Choix de param\u00e8tres de st\u00e9rilisation inappropri\u00e9s<\/strong><br>La m\u00e9thode de st\u00e9rilisation choisie n'est pas adapt\u00e9e. En particulier pour les objets \u00e0 st\u00e9riliser pr\u00e9sentant des structures complexes, ainsi que pour les dispositifs m\u00e9dicaux externes, les implants, les conteneurs rigides et les emballages surdimensionn\u00e9s ou trop lourds, il convient de respecter les param\u00e8tres de st\u00e9rilisation indiqu\u00e9s par le fabricant.<br><strong>Mesures d'am\u00e9lioration :<\/strong><br>Respectez le mode d'emploi du fabricant \u2014 St\u00e9rilisez en suivant les param\u00e8tres de st\u00e9rilisation indiqu\u00e9s par le fabricant ;<br>Pour la premi\u00e8re st\u00e9rilisation des dispositifs m\u00e9dicaux externes \u2014 Tester les param\u00e8tres de st\u00e9rilisation ;<br>Inspecter le st\u00e9rilisateur une fois par an \u2014 V\u00e9rifier les param\u00e8tres de st\u00e9rilisation ;<br>Lors de la st\u00e9rilisation de certains micro-organismes difficiles \u00e0 st\u00e9riliser, il est n\u00e9cessaire de prolonger la dur\u00e9e de st\u00e9rilisation de mani\u00e8re appropri\u00e9e. Par exemple, pour st\u00e9riliser l'agent pathog\u00e8ne responsable de la maladie de la vache folle (enc\u00e9phalopathie spongiforme bovine) et les prions, il faut prolonger la dur\u00e9e de st\u00e9rilisation.<br><strong>III. Pr\u00e9traitement inad\u00e9quat des articles st\u00e9rilis\u00e9s<\/strong><br>Un nettoyage inefficace, qui nuit \u00e0 la p\u00e9n\u00e9tration de l'agent st\u00e9rilisant ;<br>D\u00e9montage insuffisant des instruments m\u00e9talliques ;<br>Mat\u00e9riaux d'emballage qui emp\u00eachent la vapeur de passer ;<br>les emballages de st\u00e9rilisation dont les dimensions, le poids ou la densit\u00e9 sont excessifs ;<br><strong>Mesures d'am\u00e9lioration :<\/strong><br>Effectuer un nettoyage efficace conform\u00e9ment aux exigences relatives aux articles st\u00e9rilis\u00e9s et respecter le mode d'emploi ou le guide fourni par le fabricant ;<br>D\u00e9monter les instruments m\u00e9talliques si n\u00e9cessaire ;<br>Pour les emballages herm\u00e9tiques, il convient de choisir des mat\u00e9riaux tels que les sacs en papier et les sacs en papier et plastique ;<br>Le poids des trousses d'instruments ne doit pas d\u00e9passer 7 kg, et celui des trousses de pansements ne doit pas d\u00e9passer 5 kg ;<br><strong>IV.

Cela cr\u00e9e les conditions propices \u00e0 la p\u00e9n\u00e9tration de micro-organismes ext\u00e9rieurs, ce qui peut entra\u00eener une contamination des articles st\u00e9rilis\u00e9s.<br><strong>Mesures d'am\u00e9lioration :<\/strong><br>Renforcer la formation du personnel ;<br>Veillez \u00e0 ce que le st\u00e9rilisateur soit pr\u00eat avant la st\u00e9rilisation et respectez les consignes de chargement appropri\u00e9es ;<br>Emballez les diff\u00e9rents articles s\u00e9par\u00e9ment ;<br>S\u00e9chez les objets st\u00e9rilis\u00e9s ;<br>V. \u00c9vacuation insuffisante de l'air froid<br>La temp\u00e9rature de la vapeur dans un st\u00e9rilisateur \u00e0 vapeur sous pression d\u00e9pend non seulement de la pression, mais aussi du degr\u00e9 de saturation de la vapeur. Si l'air froid pr\u00e9sent dans le st\u00e9rilisateur n'est pas enti\u00e8rement \u00e9vacu\u00e9, il est impossible d'obtenir de la vapeur satur\u00e9e, ce qui nuit \u00e0 la capacit\u00e9 de p\u00e9n\u00e9tration de la vapeur \u00e0 haute pression.<br><strong>Mesures d'am\u00e9lioration :<\/strong><br>R\u00e9glez l'altitude ;<br>Lors de la st\u00e9rilisation des d\u00e9chets, versez environ 300 \u00e0 500 ml d'eau dans le sachet de st\u00e9rilisation afin d'\u00e9viter la pr\u00e9sence de r\u00e9sidus d'air \u00e0 l'int\u00e9rieur de celui-ci ;<br>Lors de la st\u00e9rilisation d'une grande quantit\u00e9 d'articles, prolongez de mani\u00e8re appropri\u00e9e la dur\u00e9e de soufflage d'air froid ;<br>Lors de la st\u00e9rilisation de r\u00e9cipients herm\u00e9tiques munis d'un couvercle, il convient \u00e9galement d'ouvrir ou de desserrer ces couvercles avant la st\u00e9rilisation ;<br>L'autoclave Zealway est \u00e9quip\u00e9 d'un syst\u00e8me de commande intelligent dot\u00e9 de fonctions performantes.
