Lactate yog tsim los ntawm feem ntau cov ntaub so ntswg hauv tib neeg lub cev, nrog rau qib siab tshaj plaws ntawm cov khoom muaj nyob hauv cov leeg. Raws li ib txwm muaj, lactate tshem tawm sai sai los ntawm lub siabnrog me me ntawm kev tshem tawm ntxiv los ntawm ob lub raum.
Lactate tshem tawm hauv lub cev li cas?
Lactate yog cleared los ntawm cov ntshav, feem ntau los ntawm lub siab, nrog raum (10-20%) thiab cov leeg pob txha ua li ntawd mus rau qib qis dua. Lub peev xwm ntawm lub siab kom haus lactate yog qhov concentration-dependant thiab nce zuj zus raws li qib ntshav lactatence.
Lactate metabolized nyob qhov twg?
ib hnub lactate ntau lawm hauv tus neeg noj qab haus huv yog qhov ntau (kwv yees li 20 mEq / kg / d), thiab qhov no feem ntau yog metabolized rau pyruvate hauv siab, ob lub raum, thiab, kom tsawg dua, hauv siab.
Puas lactate renally cleared?
Lub raum ib txwm muaj lub luag haujlwm tseem ceeb hauv lactate metabolism. Lub raum cortex zoo nkaus li yog lub luag haujlwm tseem ceeb ntawm lactate hauv lub cev tom qab lub siab. Nyob rau hauv cov xwm txheej ntawm exogenous hyperlactatemia, raum yog lub luag haujlwm rau kev tshem tawm 25-30% ntawm tag nrho cov lactate infused.
Dab tsi ua rau lactate nce siab?
Lactic acid qib nce siab dua thaum kev tawm dag zog lossis lwm yam mob-xws li lub plawv tsis ua haujlwm, mob hnyav (sepsis), lossis poob siab-txo qis ntawm cov ntshav thiab oxygen thoob plaws lub cev.
