Nyhuv ntawm lub hnub poob ntawm cov ntshav lactate concentration

- Nov 28, 2017-

Qhov concentration ntawm lactic acid nyob rau hauv cov ntshav yuav muaj kev cuam tshuam cov kev mob ntawm lub cev, thiab nws yog ib qho tseem ceeb rau kev tshawb nrhiav cov nyhuv ntawm cov lactic acid, lactic acidosis thiab kev soj ntsuam cov yeeb tshuaj. Yog hais tias nruj heev, yuav tsum kos ntshav arterial ntsuas, tab sis lub ntsej muag tiag tiag qhia tseeb tias cov ntshav lactic acid concentration ntawm arterial ntshav thiab venous ntshav tsis muaj qhov sib txawv. Nws tau raug pov thawj tias ntshav concentration ntawm cov ntshav lactic acid yuav tsis muaj cuam tshuam los ntawm cov ntshav ntawm lub tourniquet nyob rau hauv 9Os. Txawm li cas los xij, cov ntshav lactic acid concentration nce obviously tom qab lub sij hawm kaw tau noj tshaj 120s. Qhov no yog vim qhov nruj ntawm lub tsho tiv thaiv zoo rau lub cev mus rau lub cev, qhov kev venous puv yog obviously cov neeg kawm ntawv, tsuas yog thaiv cov venous reflux, tiam sis tsis cuam tshuam rau cov hlab ntsha, cov nqaij ntshiv ntawm cov nqaij ntshiv tseem nyob tsis tseg, lub sij hawm luv luv venous maj nce mus deb, qhov siab ntawm qib siab, cov ntshav khiav ntawm perfusion tseem tswj cov qib siab, lub koom haum tsis tshwm sim rau cov hypoxia cuab. Yog li ntawd, ntev li ntev raws li lub ligation ntawm tourniquet yog tsim nyog, tom qab lub tourniquet yog tus yuam sij rau kom tiav cov ntshav extraction sai li sai tau. Raws li lub ntsej muag soj ntsuam, tom qab tourniquet, cov ntshav siv zog siv ua haujlwm tiav hauv 90s. Yog li, rau cov neeg laus, rog, mob loj, lub cev qhuav dej, tsis muaj ntshav hlab ntsha, tsis tshua muaj ntshav siab, thiab lwm cov neeg mob, vim tias qhov teeb meem ntawm kev siv ntshav, cov ntshav qis tsis zoo, cov ntshav lactic acid concentration nrhiav tau tied ntshav, kom txo tau qhov mob ntawm cov neeg mob, txo qhov nyuaj ntawm kev ua haujlwm.
