Cov nyhuv ntawm cov hlab ntsha endotracheal (ETTs) impregnated nrog chlorhexidine (CHX) thiab silver carbonate (antiseptic ETTs) tiv thaiv Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, Acinetobacter baumannier nrog rau cov kab mob Enterobacter. Related pneumonia (VAP)], raug soj ntsuam nyob rau hauv ib qho kev kuaj pa kab mob.Antiseptic ETTs thiab tswj ETTs (unimpregnated) tau muab tso rau hauv kab lis kev cai raj ib nrab-sau nrog agar media (airway model) yav dhau los kis ntawm qhov chaw nrog 10 (8) cfu / mL ntawm cov kab mob uas tau xaiv.Tom qab tsib hnub ntawm incubation, cov kab mob colony suav rau txhua ntu ETT tau txiav txim siab.Swabs ntawm proximal thiab distal kawg ntawm agar ib ntsuj av nyob rau hauv antiseptic thiab tswj qauv tau subcultured.Cov theem pib thiab seem CHX, (tsib hnub tom qab cog hauv cov qauv) tau txiav txim siab.Kab lis kev cai ntawm cov tshuaj tua kab mob ETTs tau nthuav tawm cov kab mob los ntawm kev kuaj kab mob xws li 1-100 cfu / raj, piv nrog kwv yees li 10 (6) cfu / raj rau kev tswj hwm ETTs (P <0.001).Subcultures los ntawm qhov sib thooj thiab qhov kawg ntawm cov kab mob agar pom qhov tsawg lossis tsis muaj kev loj hlob ntawm cov tshuaj tua kab mob ETTs piv nrog cov tswj ETTs (P <0.001).Tus nqi ntawm CHX khaws cia hauv cov tshuaj tua kab mob ETTs tom qab tsib hnub ntawm kev cog qoob loo yog qhov nruab nrab ntawm 45% ntawm thawj theem.Antiseptic ETTs tiv thaiv kab mob colonization nyob rau hauv cov pa qauv thiab tseem khaws cov tshuaj tua kab mob tseem ceeb.Cov txiaj ntsig no qhia tau hais tias qhov ua tau zoo ntawm cov tshuaj tua kab mob-impregnated ETTs hauv kev tiv thaiv kev loj hlob ntawm cov kab mob pathogens uas cuam tshuam nrog VAP tuaj yeem sib txawv nrog cov kab mob sib txawv.Copyright 2004 Lub Tsev Kho Mob Infection Society
