Crystalloid kua muaj nuj nqi txhawm rau nthuav cov ntim hauv cov hlab ntsha yam tsis muaj kev cuam tshuam ion concentration lossis ua rau cov kua dej tseem ceeb hloov ntawm intracellular, intravascular, thiab interstitial chaw. Hypertonic cov kev daws teeb meem xws li 3% cov tshuaj ntsev ntsev muaj cov kua qaub ntau dua li cov uas pom hauv tib neeg cov ntshav.
Crystalloids thiab colloids ua haujlwm li cas?
Crystalloids kua xws li cov kua qaub ib txwm muaj qhov sib npaug ntawm cov electrolyte thiab nthuav tag nrho cov khoom ntim ntxiv. Colloid solutions (dav dav faib rau hauv cov kua hluavtaws xws li hetastarch thiab ntuj xws li albumin) ua kom lub siab oncotic siab thiab yog li nthuav ntim ntawm oncotic luag.
Crystalloids ua haujlwm hauv lub cev li cas?
Crystalloid cov kev daws teeb meem yog isotonic plasma ntim expanders uas muaj electrolytes. Lawv tuaj yeem ua kom lub ntim ntim tsis hloov pauv cov tshuaj sib npaug hauv cov hlab ntsha. Qhov no yog vim lawv cov khoom isotonic, txhais tau tias lawv cov khoom nyob ze rau cov ntshav ncig hauv lub cev.
YCrystalloids yog dab tsi?
Crystalloid tej zaum yuav xa mus rau: Ib yam khoom uas, thaum yaj, tsim cov tshuaj muaj tseeb thiab muaj peev xwm dhau los ntawm cov ntaub ntawv semipermeable. Lawv tau sib cais los ntawm colloids thaum lub sij hawm lim ntshav.
Crystalloid solutions yog dab tsi?
Crystalloid kev daws, uas muaj dej-soluble electrolytes suav nrog sodium thiab chloride, tsis muaj proteinsthiab insoluble molecules. Lawv raug cais los ntawm tonicity, yog li cov isotonic crystalloids muaj tib tus nqi ntawm cov electrolytes li cov ntshav.
