Umphumela wamashubhu e-endotracheal (ETTs) afakwe i-chlorhexidine (CHX) ne-silver carbonate (i-antiseptic ETTs) ngokumelene ne-Staphylococcus aureus, i-S. aureus engamelana ne-methicillin (MRSA), i-Pseudomonas aeruginosa, i-Acinetobacter baumanniter ehambisana ne-Engenesgenes-aerorganiter inyumoniya ehlobene (VAP)], yahlolwa ngemodeli yendlela yomoya yaselabhorethri.Ama-ETT e-Antiseptic kanye nama-ETT okulawula (angamithiswanga) afakwe kumashubhu esiko agcwele ingxenye ye-agar media (imodeli yendlela yomoya) ayengcoliswe ngaphambili ngo-10(8) cfu/mL wento ekhethiwe yokuhlola.Ngemuva kwezinsuku ezinhlanu zokufukamela, izibalo zekholoni yebhaktheriya kuzo zonke izingxenye ze-ETT zanqunywa.Ama-swabs wemikhawulo esondelene ne-distal yepheshana le-agar kumamodeli e-antiseptic kanye nokulawula ayenziwe ngaphansi kwe-subcultured.Amazinga e-CHX okuqala nasele, (izinsuku ezinhlanu ngemuva kokufakwa kumodeli) anqunywa.Amasiko ama-ETT abulala amagciwane embule ukwenziwa kwekholoni ngamagciwane ahloliwe asukela ku-1-100 cfu/ithubhu, uma kuqhathaniswa ne-10(6) cfu/ishubhu yokulawula ama-ETT (P <0.001).Ama-Subcultures avela emaphethelweni aseduze nakude epheshana le-agar abonise ukukhula okuncane noma okungekho kuma-ETT amagciwane uma kuqhathaniswa nama-ETT okulawula (P <0.001).Inani le-CHX eligcinwe kuma-ETT amagciwane ngemva kwezinsuku ezinhlanu zokufakelwa laliyisilinganiso sama-45% wezinga lokuqala.Ama-ETT e-Antiseptic avimbele ukuhlangana kwebhaktheriya kumodeli yendlela yomoya futhi agcina amanani abalulekile we-antiseptic.Le miphumela ikhombisa ukuthi ukuphumelela kwe-ETTs efakwe isinqamuleli esibulalayo ekuvimbeleni ukukhula kwamagciwane ahlobene ne-VAP angase ahluke ngezinhlobonhlobo zezinto eziphilayo.Copyright 2004 The Hospital Infection Society
