Piv txwv li, vancomycin puas tau dialyzed?

Vim vancomycin muaj qhov hnyav molecular ntawm kwv yees li 1500 Da, nws tsuas yog tshem tawm los ntawm cov pa hemodialysis, uas tso cai rau kev siv sijhawm ntev heev (piv txwv li, ib koob tshuaj txhua lub lis piam). Txawm li cas los xij, ntau dua permeability (high flux) daim nyias nyias, xws li polysulfone, ntshiab 25-50% ntawm cov tshuaj.

Tsis tas li ntawd, hom kab mob dab tsi uas vancomycin kho? Vancomycin . Vancomycin yog ib qho tshuaj tua kab mob siv rau kho ib tus lej kab mob kab mob .
