NS muaj 154 mM Na+ thiab Cl-, nrog qhov nruab nrab pH ntawm 5.0 thiab osmolarity ntawm 308 mOsm / L. LR cov tshuaj muaj qhov nruab nrab pH ntawm 6.5, yog hypo-osmolar (272 mOsm / L), thiab muaj cov electrolytes zoo sib xws (130 mM Na+, 109 mM Cl- , 28 mM lactate, thiab lwm yam) rau ntshav; Yog li, nws tau suav hais tias yog ib qho ntxiv physiologically tshaj kua dua NS.
Vim li cas koj thiaj siv LR hloov NS?
Qee qhov kev tshawb fawb qhia tias lactated Ringer's yuav nyiam tshaj li cov ntsev ib txwm rau hloov cov kua dej ploj hauv cov neeg mob raug mob. Tsis tas li ntawd, ib txwm saline muaj cov ntsiab lus chloride ntau dua. Qhov no tuaj yeem ua rau lub raum vasoconstriction, cuam tshuam rau cov ntshav ntws mus rau ob lub raum.
Puas yog saline ib txwm zoo ib yam li lactated ringers?
Lactated ringers thiab ib txwm saline yog ob hom kua-hloov cov khoom. Lawv yog ob qho tib si crystalloid daws. … Lactated ringers thiab ib txwm saline kuj yog ob qho tib si isotonic daws.
LR puas kim dua NS?
Tus nqi sib txawv ntawm ib liter ntawm saline thiab liter ntawm lactated ringers (LR) yog li 25 xees. Saline yog keeb kwm yog cov kua dej siv dav tshaj plaws, tab sis qhov ntawd tsis ua pov thawj tias nws yog qhov zoo tshaj plaws.
Lactated Ringer siv rau dab tsi?
Lactated Ringer's txhaj tshuaj yog siv los hloov cov dej thiab electrolyte poob rau cov neeg mob uas muaj ntshav tsawg lossis ntshav siab. Nws kuj yog siv los ua tus neeg sawv cev alkalinizing, uas nce qib pH ntawmlub cev.
