Kungani Nasolabial unxantathu blue ulimi okwesibhakabhaka noma izindebe turning blue?

Odokotela of China lasendulo naseNdiya enamathiselwe obaluleke ngokukhethekile ukubhekana uphethwe. Kuvele kudokotela onolwazi oluthé, futhi namuhla ungenza sitholakele isimo sesikhumba, umbala walo, umswakama, iphethini semithambo, indawo kanye imibimbi ukujula, noma ukuphendula umbuzo kungani Nasolabial unxantathu okwesibhakabhaka. Ukuhlolwa inhlangano iqala ukuhlolwa lubonakaliswa, izici njalo, wesimethri futhi ingxenye izingxenye zayo ngazinye. Ngaphezu kwalokho, umbala ebalulekile isikhumba, khona edema noma ukuqubuka. Ngokwesibonelo, izinkinga isibindi noma reddening ephelezelwa ukukhathala amehlo. Uvalwe izindebe avaliwe mncane kungase kubonise nesifo (i isifo ukuvuvukala emathunjini ezinkulu). Kungenzeka ukuthi abanye balaba izimpawu particularities zomzimba womuntu, kodwa ukuze sixoshe ukwesaba, udinga kudokotela.

A uphawu izifo ezifana izinsana, ushintsho umbala lapho Nasolabial unxantathu okwesibhakabhaka. Lesi sifo libhekene okweqa 1% (ezingeni evamile) ka methemoglobin egazini, okuyinto ifomu oxidized ka-hemoglobin. I-hemoglobin - ayoni (elihlobene ne Fe2 +) amaprotheni uyakwazi reversibly ukusabela ne-oksijini ngokudlulisela yona ezicutshini zomzimba namaseli. I namachibi of Fe2 + ukuze Fe3 + kuholela ukwehla-hemoglobin okuhlushwa (ngokuguqula ukuze methemoglobin), kanye nokuntuleka oxygen umzimba, njengoba methemoglobin akakwazi ukuphakela amaseli zihlangana nomoya-mpilo izicubu. Lesi sifo kungaba ngenxa ukuntula azalwa naso we mina enzyme diaphorase futhi atholwe.

Methemoglobinemia kungenzeka ngenxa kokuthola exogenous oxidizing ejenti (isib benzocaine nemikhiqizo kamanyolo), ungakwazi ukwandisa izinga kumiswa methemoglobin izikhathi 1000. Okunye izimbangela zihlanganisa imithi elwa namagciwane zakudala (trimethoprim, sulphonamides futhi dapsone), ukubulala izinzwa engxenyeni ethile (prilocaine futhi articaine), metoclopramide noma reception nitrate (njengoba imithi, ukudla noma amanzi), eziguqulelwa nitrites, oxidizing athomu ensimbi e-hemoglobin. Abasengozini kakhulu abantwana abangaphansi kwezinyanga eziyisithupha. Uma blue ingane unxantathu Nasolabial, kubonisa yokushodelwa umoya emzimbeni wakhe.

Nokho, izinsana - akusiyo isizathu kuphela. unxantathu Nasolabial siluhlaza zinokukhubazeka inhliziyo, lapho, angene lwemithambo emithambo yegazi igazi ukushoda kwenzeka emzimbeni igazi elihlanzekile ukuthi wenza umsebenzi ethutha ezicutshini futhi emangqamuzaneni omzimba izakhi kanye nomoya-mpilo. Futhi kuholele yokushodelwa umoya emzimbeni isifo samaphaphu. Lokhu okhathazekile umsebenzi erythrocyte ukuba liyobamba i-oksijini emaphashini, lokuthumela ke ezicutshini lapho amasampuli kwenzeka-carbon dioxide futhi ukuzihlalela ke emaphashini. Kodwa kungakhathaliseki ukuthi iyini imbangela luhlaza bluish unxantathu Nasolabial kungenzeka, kungcono ubonane nodokotela.

Kuyinto Asikwazi ukushalazela izindebe okwesibhakabhaka, ikakhulukazi uma kuhambisana palpitations inhliziyo, ukukhwehlela, izinzipho bluish, nobunzima bokuphefumula, imfiva, noma uma isiguli iphonswe emlilweni. Isizathu esiyinhloko esenza izindebe babe blue - a cyanosis (central mehluko lapho ukuvula izindebe okwesibhakabhaka, futhi neuropathy - abathintekayo nemilenze). I umoya-mpilo owengeziwe egazini, ngakho-ke kuba bomvu futhi licace. igazi emithambo yegazi zibomvu amnyama ngombala ngenxa okuqukethwe encane oxygen. imithambo yegazi ngegazi emithambo yegazi, ngenxa izakhiwo optical kwesikhumba, avele blue. cyanosis Central kungenxa iziyaluyalu kwegazi noma nezinkinga emaphashini ukupholisa. Lesi sifo eba lapho ukugcwaliswa-mpilo ka lwemithambo yegazi kuyinto ≤ 85%. Izimbangela cyanosis kungaba inkinga nge isimiso sezinzwa esiyinhloko (ubuchopho ukopha, hypoxia palsy, izidakamizwa ukweqisa izidakamizwa), izifo zemigudu yokuphefumula nesifo (COPD, isifuba somoya, njll), inhliziyo (isib, ukukhubazeka), igazi (methemoglobinemia).

Ulimi futhi nesibuko okubonakala kuso isimo umzimba. Phakathi odokotela ongoti, okuyinto ngolimi angenza ukusazi ngokunembile isifo esikuphethe. On izinkinga kanye nezinso, kuvimbela ulimi okwesibhakabhaka. Uma obomvu umbala, kubonisa nezilonda noma izifo ezithile. Ulimi enamathela gastroenterologists nesithakazelo. Desquamation ka papillae kubonisa zegazi izifo igazi. Ezikhathini zasendulo, odokotela ngikholelwa ukuthi umzimba uyakwazi ukuxwayisa yezinkinga zempilo. Kwezokwelapha Oriental abe nolwazi ukuthi bathi isitho ngasinye yangaphakathi lihlotshaniswa angomunye ulimi, ngakho kukhona nokwanda ezindaweni ezithile ulimi. Ngokwesibonelo, impande ulimi ibonisa isimo emathunjini, futhi ichopho ulimi - isimo senhliziyo. uhlaka avamile ayilutho ulimi pink nge papillae abahlukene futhi nesibaya bushelelezi kubonisa isimo esihle emzimbeni.
