ʻO ka hopena o nā paipu endotracheal (ETTs) i hoʻopili ʻia me ka chlorhexidine (CHX) a me ke kalapona kālā (antiseptic ETTs) e kūʻē iā Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, Acinetobacter baumannii, a me Enterobacter aerogenes-e pili ana. ʻO ka pneumonia pili (VAP)], ua loiloi ʻia ma ke ʻano hoʻohālike ea.Hoʻokomo ʻia nā ETT Antiseptic a me nā ETT mana (unimpregnated) i loko o nā paipu moʻomeheu i hoʻopiha ʻia me ka media agar (model airway) i hoʻohaumia mua ʻia ma ka ʻili me 10(8) cfu/mL o ka mea hoʻāʻo i koho ʻia.Ma hope o ʻelima mau lā o ka incubation, ua hoʻoholo ʻia ka helu ʻana o nā kolo bacteria ma nā ʻāpana ETT āpau.Hoʻopili ʻia nā swabs o nā ʻaoʻao proximal a me nā ʻaoʻao o ka ʻāpana agar i nā kumu hoʻohālike antiseptic a me ka mana.Ua hoʻoholo ʻia ka pae mua a me ke koena CHX, (ʻelima mau lā ma hope o ka hoʻopili ʻana i ke kumu hoʻohālike).Ua hōʻike ʻia nā moʻomeheu o nā ETT antiseptic i ka noho ʻana e nā pathogens i hoʻāʻo ʻia mai ka 1-100 cfu/tube, i hoʻohālikelike ʻia me kahi kokoke i 10(6) cfu/tube no nā ETT mana (P <0.001).ʻO nā subcultures mai nā ʻaoʻao proximal a me nā ʻaoʻao mamao o ka ʻāpana agar i hōʻike liʻiliʻi a ʻaʻohe ulu i nā ETT antiseptic i hoʻohālikelike ʻia me nā ETT mana (P <0.001).ʻO ka nui o CHX i mālama ʻia i loko o nā ETT antiseptic ma hope o ʻelima mau lā o ka hoʻokomo ʻana he awelika o 45% o ka pae mua.Ua pale aku nā antiseptic ETT i ka noho ʻana o ka maʻi bacteria ma ke ʻano ea a mālama pū kekahi i ka nui o ka antiseptic.Hōʻike kēia mau hopena i ka hiki ke hoʻololi ʻia ka maikaʻi o nā antiseptic-impregnated ETTs i ka pale ʻana i ka ulu ʻana o nā pathogens bacteria e pili ana me VAP me nā mea ola like ʻole.Copyright 2004 The Hospital Infection Society
