Zotsatira za machubu a endotracheal (ETTs) opangidwa ndi chlorhexidine (CHX) ndi silver carbonate (antiseptic ETTs) motsutsana ndi Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, Acinetobacter baumanniter, ndi Engenesgenes-aerorganiter chibayo chogwirizana (VAP)], adawunikidwa munjira ya labotale.Ma Antiseptic ETTs ndi control ETTs (osanalowedwe) adayikidwa m'machubu achikhalidwe odzazidwa theka ndi agar media (model ya airway) yomwe idayipitsidwa kale ndi 10(8) cfu/mL yamoyo woyesedwa wosankhidwa.Pambuyo pa masiku asanu a incubation, chiwerengero cha mabakiteriya pamagulu onse a ETT chinatsimikiziridwa.Masamba a proximal ndi distal malekezero a agar thirakiti mu antiseptic ndi njira zowongolera anali osakhazikika.Miyezo yoyamba ndi yotsalira ya CHX, (masiku asanu pambuyo pa kuikidwa mu chitsanzo) adatsimikiziridwa.Zikhalidwe za antiseptic ETTs zimavumbulutsa koloni ndi tizilombo toyambitsa matenda omwe anayesedwa kuyambira 1-100 cfu/chubu, poyerekeza ndi pafupifupi 10(6) cfu/chubu cha ma ETTs owongolera (P <0.001).Ma subcultures ochokera ku malekezero akutali ndi akutali a thirakiti la agar adawonetsa kukula pang'ono kapena kusakhalapo kwa antiseptic ETTs poyerekeza ndi ma ETT owongolera (P <0.001).Kuchuluka kwa CHX yosungidwa mu ETTs yophatikizika pambuyo pa masiku asanu atayikidwa inali pafupifupi 45% ya mlingo woyamba.Ma Antiseptic ETTs adalepheretsa kukhazikika kwa mabakiteriya munjira yapanjira komanso kusunga ma antiseptic ambiri.Zotsatirazi zimasonyeza kuti mphamvu ya ETTs yopangidwa ndi antiseptic-impregnated ETTs poletsa kukula kwa tizilombo toyambitsa matenda okhudzana ndi VAP akhoza kusiyana ndi zamoyo zosiyanasiyana.Copyright 2004 The Hospital Infection Society
