Qhov sib txawv tseem ceeb ntawm crystalloids thiab colloids yog tias cov colloids muaj ntau cov molecules loj dua li ntawm crystalloids.
Crystaloid thiab colloid cov kev daws teeb meem muaj txiaj ntsig zoo rau kev kho mob. Yog li, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm crystalloids thiab colloids thiaj li txiav txim siab thaum twg siv cov kev daws teeb meem no. Thaum xav txog lawv cov chemistry, raws li qhov loj ntawm cov molecules lawv muaj, muaj qee qhov sib txawv ntawm crystalloids thiab colloids.
YCrystalloids yog dab tsi?
Crystalloid yog ib yam khoom uas peb tuaj yeem ua kom crystallize. Cov no yog aqueous daws ntawm ntsev, minerals los yog lwm yam dej-soluble tshuaj. Saline, uas yog aqueous tov ntawm sodium chloride, yog crystalloid. Txij li thaum lawv muaj me me molecules, lawv tuaj yeem dhau los ntawm tag nrho cov cell membranes thiab nkag mus rau hauv cov hlwb. Thaum peb txhaj cov tshuaj rau cov ntshav, lawv tawm ntawm cov hlab ntsha thiab xa mus sai sai. Peb tuaj yeem khaws cia rau hauv chav tsev kub thiab lawv tuaj yeem muaj cov electrolytes lossis tsis yog electrolytes. Vim yog cov laj thawj no, cov tshuaj crystalloid muaj txiaj ntsig zoo hauv tshuaj.
Daim duab 01: Dej ntsev los yog dej ntsev
Lawv yog ib qho tseem ceeb xws li ntim expanders, ua ib qho nruab nrab los muab cov electrolytes tsis txaus rau lub cev, thiab lwm yam. Qhov zoo ntawm cov tshuaj crystalloid yog tias lawv pheej yig, yooj yim khaws cia, muaj lub neej ntev, siv tau zoo, tsawg. kev mob tshwm sim, yooj yim los npaj thiab npaj tau yooj yim; kuj, muaj ntau yam formulations muaj. Txawm li cas los xij, kev siv cov kua dej crystalloid ntau dhau rau kev kho mob tuaj yeem ua rau peripheral thiab pulmonary oedema.
Dab tsi yog Colloids?
Colloidal tov yog homogeneous sib tov, tab sis nws tuaj yeem ua tau zoo ib yam (piv txwv li, mis nyuj, pos). Cov khoom hauv cov tshuaj colloidal yog qhov loj me me (loj dua li cov molecules) thaum piv rau cov khoom hauv cov kev daws teeb meem thiab kev ncua lossis crystalloids. Tab sis zoo li cov khoom hauv cov kev daws teeb meem, lawv tsis pom qhov muag liab qab, thiab peb tsis tuaj yeem lim siv cov ntawv lim. Peb npe cov khoom nyob rau hauv ib tug colloid li cov khoom dispersed, thiab cov dispersing nruab nrab yog analogous rau hnyav nyob rau hauv ib tug tov.
Daim duab 02: Mis yog Colloid
Raws li cov khoom tawg thiab qhov nruab nrab, muaj ntau hom colloids. Piv txwv li, yog hais tias ib tug gas disperses nyob rau hauv ib tug kua nruab nrab, lub resulting colloid yog 'ua npuas ncauj' (piv txwv li, whipped cream). Yog tias ob lub kua ua ke, lub colloid yog ib qho emulsion (piv txwv li, mis nyuj). Ntshav kuj yog ib qho colloid. Cov khoom xa tawm hauv qhov nruab nrab colloidal tsis nyob hauv yog tias nws tseem tshuav. Colloidal daws yog translucent los yog opaque. Qee lub sij hawm peb tuaj yeem cais tawm cov khoom hauv colloid los ntawm centrifugation lossis coagulation. Piv txwv li, cov proteins hauv cov mis nyuj coagulate thaum peb muab cua sov los yog peb ntxiv cov kua qaub.
Feem ntau, peb siv cov tshuaj colloid xws li hetastarch, dextran, plasma protein daws, thiab lwm yam hauv kev kho mob science. Txij li thaum lawv tseem tshuav nyob rau hauv cov hlab ntsha, colloids muaj txiaj ntsig zoo dua los siv rau kev nthuav dav cov hlab ntshav ntau dua li crystalloids. Txawm li cas los xij, kev siv ntau dhau ntawm colloids tuaj yeem ua rau muaj kev phiv xws li peripheral thiab pulmonary edema thiab plawv tsis ua haujlwm.
Qhov txawv ntawm Crystalloids thiab Colloids yog dab tsi?
Crystalloids hais txog ib yam khoom uas peb tuaj yeem crystallize thaum colloids xa mus rau cov tshuaj uas muaj cov khoom tawg thiab qhov nruab nrab dispersing. Raws li qhov sib txawv tseem ceeb ntawm crystalloids thiab colloids, peb tuaj yeem hais tias lawv txawv ntawm ib leeg raws li qhov loj me; colloids muaj molecules loj dua li crystalloids ua. Tsis tas li ntawd, muaj lwm qhov sib txawv ntawm crystalloids thiab colloids. Qhov ntawd yog, peb tuaj yeem khaws cov crystalloids ntawm chav sov thaum peb tsis tuaj yeem khaws cov colloids ntawm chav sov.
Summary – Crystalloids vs Colloids
Crystaloids thiab colloids yog ob lo lus uas peb siv los sau npe ob hom tshuaj uas muaj cov khoom. Qhov sib txawv ntawm crystalloids thiab colloids yog tias cov colloids muaj ntau cov molecules loj dua li ntawm crystalloids.
