Crystalloid kua ua haujlwm kom nthuav dav intravascular ntim 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.
Vim li cas Crystalloids siv rau kev poob siab?
Teb: Crystalloid cov kev daws teeb meem tseem yog cov kua dej resuscitative xaiv rau cov neeg mob sepsis thiab septic shock. Balanced crystalloid solutions tuaj yeem txhim kho cov txiaj ntsig ntawm tus neeg mob thiab yuav tsum raug suav tias yog lwm txoj hauv kev rau 0.9% ib txwm saline (thaum muaj) hauv cov neeg mob sepsis.
Vim li cas Crystalloids nyiam tshaj colloids?
Crystalloids muaj cov molecules me me, yog pheej yig, siv tau yooj yim, thiab muab cov kua dej resuscitation tam sim ntawd, tab sis yuav ua rau oedema. Colloids muaj cov molecules loj dua, raug nqi ntau dua, thiab tuaj yeem muab cov ntim nrawm dua hauv qhov chaw intravascular, tab sis tuaj yeem ua rau muaj kev tsis haum tshuaj, ntshav txhaws, thiab lub raum tsis ua haujlwm.
Vim li cas peb thiaj muab Crystalloids?
Crystalloid cov ntsiab lus feem ntau yog siv los ua kom cov hlab ntshav ntim thaum nws txo qis. Qhov kev txo qis no tuaj yeem tshwm sim los ntawm hemorrhage, lub cev qhuav dej lossis poob dej thaum phais. Cov kua dej crystalloid feem ntau yog sodium chloride 0.9%, feem ntau hu ua saline 0.9%.
Koj muab dabtsi rauhypovolemic poob siab?
Isotonic crystalloid cov kev daws teeb meem feem ntau yog muab rau intravascular repletion thaum poob siab thiab hypovolemia. Cov tshuaj colloid feem ntau tsis siv. Cov neeg mob uas lub cev qhuav dej thiab txaus circulatory ntim feem ntau muaj dej dawb tsis txaus, thiab cov tshuaj hypotonic (xws li, 5% dextrose hauv dej, 0.45% saline) yog siv.
