Kev tsim tawm lossis txo qis kev siv ntawm cov kab mob lactic acid ua rau txo qis cov kua qaub-puag hauv lub cev. Qhov no "acidification" provokes loj pathological mob - lactic acidosis.

Cov lactate ntau dhau los qhov twg los?

Cov dej qabzib metabolism yog cov txheej txheem ua haujlwm nyuaj, txoj haujlwm tsis yog tsuas yog los ntawm lub cev nrog "lub zog", tab sis kuj koom nrog "kev ua pa ntawm lub hlwb."

Nyob hauv kev cuam tshuam ntawm biochemical catalysts, cov piam thaj molecule decomposes thiab tsim ob pyruvic acid lwg me me (pyruvate). Nrog cov pa oxygen txaus, pyruvate dhau los ua cov khoom siv rau feem ntau cov kev ua tiav metabolic hauv lub cell. Thaum muaj pa oxygen tshaib plab, nws hloov mus ua lactate. Qhov me me ntawm nws yog qhov tsim nyog rau lub cev, lactate xa rov qab rau daim siab thiab hloov pauv rov qab mus rau kua nplaum. Cov ntaub ntawv no cov xaiv yaam khoom ntawm glycogen.

Nquag, qhov piv ntawm pyruvate thiab lactate yog 10: 1, nyob hauv qab ntawm lwm yam sab nraud, qhov sib npaug tuaj yeem hloov mus. Muaj ib qho mob uas yuav txo tau txoj sia - lactic acidosis.

Qhov tseeb uas ua rau muaj kev nce siab ntawm cov tshuaj lactic acid muaj xws li:

  • cov ntaub so ntswg hypoxia (ua kom lub cev tsis haum, lom carbon dioxide lom, mob hnyav txaus, qaug dab peg);
  • tsis muaj ntaub so ntswg oxygen starvation (lom nrog methanol, cyanides, biguanides, lub raum / nplooj siab tsis ua haujlwm, oncology, mob hnyav, mob ntshav qab zib mellitus).

Ib qho kev nce qib tseem ceeb ntawm cov qib lactic acid hauv lub cev yog qhov mob uas yuav tsum tau ua rau lub tsev kho mob sai. Txog li 50% ntawm cov neeg uas pom tau yog tuag!

Ua rau Cov Mob Ntshav Qab Zib Lactic Acidosis

Lactic acidosis yog ib qho mob tsis tshua muaj tshwm sim, ntau dua li ib nrab ntawm cov tshaj tawm hais tias tshwm sim hauv cov neeg mob ntshav qab zib.
Hyperglycemia ua rau qhov tseeb tias cov piam thaj hauv ntshav ntau tshaj yog hloov mus rau lactic acid. Insulin deficiency cuam tshuam kev hloov pauv ntawm pyruvate - qhov uas tsis muaj lub ntuj catalyst ua rau kev nce hauv cov synthesis ntawm lactate. Pheej mob ua rau lub cev ua rau lub hlwb ntev dua ntawm cov hlwb, ua rau muaj teeb meem ntau yam (mob raum, mob siab, hlab plawv) uas ua rau lub cev muaj zog ua rau lub plab nqus tau.

Kev faib tawm ntau ntawm cov kev tawm tsam ntawm cov kab mob lactic acidosis tshwm sim hauv cov neeg uas tau noj tshuaj hypoglycemic. Niaj hnub nimno biguanides (metformin) tsis ua rau kom muaj kev sib txuam ntau ntxiv ntawm cov kab mob lactic acid hauv lub cev, txawm li cas los xij, yog tias muaj ntau qhov kev ua kom mob (kis tus kab mob, mob, mob lom, haus cawv, haus dej cawv ntau dhau ntawm lub cev) tshwm sim, lawv tuaj yeem pab ua kom muaj kab mob.

Cov tsos mob ntawm tus kab mob lactic acidosis hauv ntshav qab zib

Daim duab dav dav ntawm kev nthuav qhia yog tib yam li nrog ntshav qab zib kom ntau
Kev nkees nkees, tsis muaj zog, nkees nkees, nyob rau hauv cov ceg ntawm lub plab yog pom, xeev siab, ntuav feem ntau yuav ntuav. Lactic acidosis yog qhov txaus ntshai vim tias nws loj hlob sai sai hauv ob peb teev. Tom qab cov tsos mob uas nquag muaj ntshav qab zib, zawv plab, ntuav, thiab tsis meej pem tshwm sim sai heev. Tib lub sijhawm, tsis muaj lub cev ketone hauv cov zis, tsis muaj ntxhiab tsw ntawm acetone.

Lactic acid coma yog ib qho txaus ntshai tshaj plaws, qhov kwv yees ntawm txoj kev tawm ntawm nws yog qhov tsis zoo!
Yog tias qhov kev sim ntsuas ntawm qhov pom ntawm qhov txiav txim siab ketoacidosis thiab ntshav qabzib tsuas qhia tias muaj suab thaj ntau, thaum muaj mob nqaij, koj yuav tsum hu rau lub tsheb thauj neeg mob tam sim ntawd! Yog tias koj tsis ua dab tsi thiab sim ua kom tsis txhob tus mob tus kheej, tom qab ntawd qhov kev txo qis hauv ntshav siab, ua pa tsis tshua muaj thiab tsis muaj suab nrov, ua txhaum ntawm lub plawv lub plawv, yuav ua raws li tsis nco qab.

Qhov sib txawv tseem ceeb ntawm cov kab mob lactic acidosis thiab ketoacidosis lossis hyperglycemia hnyav yog qhov muaj mob ntawm cov leeg, uas feem ntau piv nrog txhaws cov leeg ntawm cov kis las.

Kev Kho Mob hyperlactatacidemia

Kev kuaj mob ntawm cov kab mob lactic acidosis tsuas yog ua tau nrog rau kev kuaj sim. Ua ntej tshaj plaws, lawv sim ua kom pom qhov txawv acidosis. Ntsig qib lactate los ntawm 5.0 mmol / L thiab ph tsawg dua 7.25 tso cai rau koj kom ntseeg tau cov tshuaj lactic acid lom ntawm lub cev. Muaj qib kua qaub-qib pib hauv qab 6.8 yog qhov tseem ceeb.
Kev kho mob muaj nyob hauv kev kho kom rov qab ua kom muaj kua qaub-puag, kom tshem tawm cov teeb meem hyper hypercemia
  1. Yog tias ph qis dua 7.0, txoj hauv kev los cawm tus neeg mob tsuas yog mob hemodialysis - ntshav ntxuav.
  2. Txhawm rau tshem tawm cov pa roj carbon ntau dhau, yuav tsum ua kom lub ntsws tsis txhob tawg.
  3. Hauv cov teeb meem me, nrog lub sijhawm mus rau cov kws tshaj lij, cov dej ntws tawm nrog cov tshuaj alkaline (sodium bicarbonate, trisamine) tau txaus. Tus nqi tswj hwm yog nyob ntawm lub hauv siab txhaws. Thaum koj cov metabolism hauv kev ua kom zoo dua, koj tuaj yeem pib txo qis koj cov ntshav kev ntshav siab. Rau qhov no, ntau yam qauv rau kev tswj cov kua nplaum nrog insulin tuaj yeem siv. Raws li txoj cai, qhov no yog 2-8 units. nrog ceev ntawm 100-250 ml / h.
  4. Yog hais tias tus neeg mob muaj lwm yam cuam tshuam nrog cov kab mob lactic acidosis (lom, ntshav liab), lawv txoj kev kho yog nqa tawm raws li lub ntsiab cai classical.
Nws yuav luag tsis yooj yim sua los muab cov kev pabcuam ua ntej rau cov cim ntawm lactic acidosis. Txhawm rau txo cov kua qaub ntawm cov ntshav sab nraum lub tsev kho mob yuav tsis ua haujlwm. Alkaline ntxhia dej thiab dej qab zib cov kev daws teeb meem yuav tsis coj mus rau qhov txiaj ntsig yam xav tau. Nrog rau kev ntsuas ntshav qis los yog kev poob siab, kev siv tshuaj dopamine tsuas tsim nyog. Nws yog ib qho tsim nyog kom ntseeg tau tias cov cua ntws ntau tshaj plaws, thaum tsis muaj lub ncoo pa hauv ncoo lossis lub nqus pa, koj tuaj yeem qhib lub vaum vaum thiab qhib txhua lub qhov rais.

Tus mob txhawm rau kom rov zoo los ntawm lactic acidosis yog neeg pluag. Txawm tias kev kho mob kom tsim nyog thiab nkag mus cuag sijhawm rau cov kws kho mob tsis tuaj yeem lav tias yuav cawm tau txoj sia. Yog li, cov neeg mob ntshav qab zib, tshwj xeeb tshaj yog cov uas siv cov tshuaj metformin, yuav tsum mloog zoo rau lawv lub cev thiab khaws lawv cov piam thaj hauv cov hom phiaj.
