Yog vim li cas nasolabial daim duab peb sab xiav xiav tus nplaig los yog daim di ncauj xiav xa?

Cov kws kho mob ntawm ancient Tuam Tshoj thiab Is Nrias teb txuas tshwj xeeb tseem ceeb mus fim cov mob. Ib tug tej kws kho mob, thiab niaj hnub no yuav ua rau ib tug mob ntawm daim tawv nqaij mob, nws cov xim, ya raws, vascular txawv, qhov chaw thiab qhov tob ntawm wrinkles, los yog mus rau teb rau lo lus nug yog vim li cas lub nasolabial daim duab peb sab xiav. Soj ntsuam qhov chaw pib nrog ib tug kev soj ntsuam ntawm nws kev hais lus, kev nta, symmetry thiab kev faib ua feem ntawm nws cov neeg qhov chaw. Nyob rau hauv tas li ntawd, tseem ceeb heev xim ntawm daim tawv nqaij, muaj cov edema los sis tawm pob. Piv txwv li, lub siab teeb meem los yog reddening nrog qaug zog ntawm ob lub qhov muag. Nruj nreem kaw nyias daim di ncauj yuav qhia mob plab (ib tug inflammatory kab mob ntawm txoj hnyuv loj). Nws yog tau hais tias ib co ntawm cov tej yam tshwm sim yog tus particularities ntawm tib neeg lub cev, tab sis nyob rau hauv thiaj li yuav dispel ntshai, koj yuav tsum sab laj nrog ib tug kws kho mob.

Ib tug kos npe rau ntawm tej kab mob raws li cov me nyuam mos, yog ib tug hloov nyob rau hauv cov xim thaum lub nasolabial daim duab peb sab xiav. Tus kab mob no yog yus muaj los ntawm ntau tshaj ntawm 1% (ib txwm theem) ntawm methemoglobin nyob rau hauv cov ntshav, uas yog ib qho oxidized daim ntawv ntawm hemoglobin. Hemoglobin - ferrous (txuam nrog Fe2 +) protein muaj peev xwm ntawm reversibly reacting nrog cov pa thiab hloov nws mus rau hauv lub cev nqaij thiab lub hlwb. Cov oxidation ntawm Fe2 + mus Fe3 + ua rau ib tug txo nyob rau hauv hemoglobin concentration (los ntawm hloov nws mus rau methemoglobin), thiab tsis muaj kev oxygen nyob rau hauv lub cev, vim methemoglobin yog tsis muaj peev xwm mus muab lub hlwb nrog rau oxygen thiab cov ntaub so ntswg. Tus kab mob no yuav ua tau vim congenital tsis muaj peev xwm ntawm cov enzyme diaphorase kuv thiab mas yuav kis tau.

Methemoglobinemia zaum yuav tshwm sim raws li ib tug tshwm sim uas tau txais exogenous oxidizing agents (e.g., benzocaine thiab nitrates), yuav ua rau kom tus nqi ntawm tsim ntawm methemoglobin 1000 lub sij hawm. Lwm yam ua rau muaj xws li classic tshuaj tua kab mob (trimethoprim, sulphonamides thiab dapsone), lub zos anesthetics (prilocaine thiab articaine), metoclopramide los yog txais tos nitrate (raws li ib tug tshuaj, khoom noj khoom haus los yog cov dej), uas yog hloov dua siab tshiab rau nitrites, oxidizing hlau atoms nyob rau hauv hemoglobin. Tshwj xeeb yog lam tau lam ua yog cov me nyuam nyob rau hauv rau lub hlis. Yog hais tias ib tug me nyuam nasolabial daim duab peb sab xiav, nws qhia tias ib tug tsis muaj oxygen nyob rau hauv nws lub cev.

Txawm li cas los, cov me nyuam mos - nws tsis yog tus tsuas yog vim li cas. Nasolabial daim duab peb sab yog xim xiav nrog lub plawv tsis xws luag, thaum twg, vim mus rau hauv lub arterial venous ntshav tsis txaus tshwm sim nyob rau hauv lub cev ntawm ntshiab ntshav uas ua cov kev ua ntawm kev thauj mus cov ntaub so ntswg thiab hlwb ntawm lub cev ntawm cov as-ham thiab oxygen. Tsis tas li ntawd ua rau ib tug tsis muaj oxygen nyob rau hauv lub cev pulmonary kab mob. Qhov no disturbed muaj nuj nqi ntawm erythrocytes mus ntes pa nyob rau hauv lub ntsws, shipping nws mus rau cov ntaub so ntswg nyob rau hauv uas sampling tshwm sim ntawm cov pa roj carbon dioxide thiab cais nws nyob rau hauv ob lub ntsws. Tab sis txawm qhov ua rau xiavlus Hawj txawm nyob rau hauv lub nasolabial daim duab peb sab tej zaum yuav, yuav tsum tau nrog ib tug kws kho mob.

Nws yog tsis yooj yim sua rau las mees cov kob xiav daim di ncauj, tshwj xeeb tshaj yog yog hais tias nws yog nrog los ntawm lub plawv palpitations, hnoos, blue tes, teeb meem ua tsis taus pa, kub taub hau, los yog yog hais tias tus neeg mob raug pov rau hauv qhov hluav taws kub. Lub ntsiab yog vim li cas yog vim li cas ob daim di ncauj twb xiav - ib tug cyanosis (central txim hluav taws xob thaum txoj siav xiav daim di ncauj, thiab peripheral - cuam tshuam nqua). Qhov ntau oxygen hauv cov ntshav, ces nws yog redder thiab brighter. Venous ntshav yog tsaus liab nyob rau hauv cov xim vim lub me me cov ntsiab lus ntawm cov pa. Cov hlab ntsha nrog venous ntshav, vim tus kho qhov muag khoom ntawm daim tawv nqaij, yuav tshwm sim xiav. Central cyanosis yog vim lub plawv mob los yog mob ntsws cua teeb meem. Tus kab mob muaj thaum lub oxygen saturation ntawm arterial ntshav yog ≤ 85%. Cov ua rau cyanosis yuav ua tau ib qho teeb meem nrog lub hauv paus poob siab system (hlwb hemorrhage, cerebral hypoxia, tshuaj overdose), ua pa kab mob (COPD, mob hawb pob, thiab lwm yam), lub plawv (eg, tsis xws luag), ntshav (methemoglobinemia).

Lus tseem yog ib daim iav xav hauv lub xeev ntawm tus kab mob. Ntawm cov kws kho mob yog tshwj xeeb, uas nyob rau hauv cov lus ntawm yuav ua tau ib tug muaj tseeb kuaj mob. Nyob rau cov teeb meem nrog rau ob lub raum, tiv thaiv xiav tus nplaig. Yog hais tias cov xim liab, nws qhia tias mob los yog kab mob. Tus nplaig txheej xav gastroenterologists. Desquamation ntawm papillae qhia hematologists rau cov ntshav kab mob. Nyob rau hauv ancient sij hawm, cov kws kho mob ntseeg tau hais tias lub cev muaj peev xwm ceeb toom rau noj qab haus huv tej teeb meem. Nyob rau hauv oriental tshuaj muaj kev txawj ntse uas hais tias txhua internal hloov yog txuam nrog ib tug cheeb tsam ntawm cov lus, thiaj li muaj ib qho kev nce nyob rau hauv tej qhov chaw ntawm cov lus. Piv txwv li, cov hauv paus hniav ntawm tus nplaig qhia cov xwm txheej ntawm cov hnyuv, thiab lub ntsis ntawm tus nplaig - ib tug mob ntawm lub plawv. Tsis tu ncua ntaem daj liab tus nplaig nrog cov papillae thiab du quav qhia ib tug zoo ntawm lub cev.
