Ndi chitukuko cha chithandizo chamankhwala padziko lonse lapansi, makina oletsa ululu, ma ventilators ndi zida zina zakhala zida zachipatala zodziwika bwino m'zipatala.Zida zoterezi nthawi zambiri zimakhudzidwa ndi tizilombo toyambitsa matenda, makamaka mabakiteriya a Gram-negative (kuphatikizapo Acinetobacter baumannii, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Pseudomonas syringae, Klebsiella pneumoniae, Bacillus subtilis, etc.);Mabakiteriya a gram-positive (kuphatikiza Corynebacterium diphtheriae, Streptococcus pneumoniae, Streptococcus haemolyticus, coagulase-negative Staphylococcus ndi Staphylococcus aureus, etc.) mafangasi (kuphatikiza Candida, bowa wa filamentous, bowa wofanana ndi yisiti, yeast of yeast).

Kafukufuku wokhudzana ndi mafunso omwe adafunsidwa adachitidwa ndi Perioperative Infection Control Branch ya Chinese Society of Cardiothoracic and Vascular Anesthesia kumapeto kwa 2016, ndi ogona okwana 1172 omwe adachita nawo bwino, 65% omwe anali ochokera ku zipatala zamaphunziro apamwamba m'dziko lonselo, ndi zotsatira zake. adawonetsa kuti kuchuluka kwa anthu omwe sanapatsidwe mankhwala ophera tizilombo komanso nthawi zina kupha tizilombo toyambitsa matenda mkati mwa makina opangira opaleshoni, ma ventilator, ndi zida zina kunali kopitilira 66%.

Kugwiritsa ntchito zosefera zolowera kupuma kokha sikumalekanitsa kufala kwa tizilombo toyambitsa matenda mkati mwa zida komanso pakati pa odwala.Izi zikuwonetsa kufunikira kwachipatala pakupha tizilombo toyambitsa matenda ndi kutsekereza mkati mwa zida zachipatala kuti tipewe kutenga matenda osiyanasiyana komanso kupititsa patsogolo ntchito zachipatala.

Pali kusowa kwa miyezo yofananira yokhudzana ndi njira zophera tizilombo toyambitsa matenda komanso kutseketsa mabakiteriya amkati mwa makina, chifukwa chake ndikofunikira kupanga zofananira.

Mapangidwe amkati a makina opangira opaleshoni ndi ma ventilators ayesedwa kuti akhale ndi mabakiteriya ambiri a tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda, ndipo matenda a nosocomial omwe amayamba chifukwa cha kuipitsidwa kwa tizilombo toyambitsa matenda akhala akudetsa nkhawa kwa nthawi yaitali.

Kupha tizilombo toyambitsa matenda mkati mwake sikunathetsedwa bwino.Ngati makinawo atsekedwa kuti aphedwe ndi tizilombo toyambitsa matenda pambuyo pa ntchito iliyonse, pali zovuta zoonekeratu.Kuphatikiza apo, pali njira zitatu zophera tizilombo toyambitsa matenda, imodzi ndi kutentha kwambiri komanso kuthamanga kwambiri, ndipo zida zambiri sizingaphatikizidwe ndi tizilombo pa kutentha kwakukulu komanso kuthamanga kwambiri, zomwe zingayambitse kukalamba kwa payipi ndi malo osindikizira, zomwe zimakhudza kutsekeka kwa mpweya. za zowonjezera ndikuwapangitsa kuti asagwiritsidwe ntchito.Zina ndi disinfection ndi njira yothetsera disinfection, komanso chifukwa cha disassembly pafupipafupi kumayambitsa kuwonongeka kwa zolimba, pamene disinfection wa ethylene oxide, komanso ayenera kukhala ndi masiku 7 kusanthula kuti amasulidwe zotsalira, adzachedwa ntchito, kotero izo. osafunidwa.

Poganizira zofunikira zachangu pakugwiritsa ntchito kuchipatala, m'badwo waposachedwa wazinthu zovomerezeka: YE-360 mndandanda wa anesthesia kupumira dera makina ophera tizilombo toyambitsa matenda.
