Teko ea methylene putsoa - Moriana
Teko ea methylene putsoa - Moriana

Teko ea methylene putsoa ke teko ea ho fumana mofuta kapa ho phekola methemoglobinemia, lefu la mali.

Mofani oa tlhokomelo ea bophelo o thatela lebanta le tiileng kapa cuff ea khatello ea mali letsohong la hau le kaholimo. Khatello e etsa hore methapo e ka tlasa sebaka seo e tlale mali.

Letsoho le hloekisoa ka sebolaea likokoana-hloko (sebolaya-mafu). Ho kenngoa nale ka mothapong oa hau, hangata haufi le bokahare ba setsoe kapa morao oa letsoho. Phala e tšesaane, e bitsoang catheter, e kenngoa mothapong. (Sena se ka bitsoa IV, se bolelang ho kenella methapong). Ha tube e ntse e lula, nale le li-tournique lia tlosoa.

Phofo e botala bo lefifi e bitsoang methylene blue e kena ka har'a mothapo oa methapo. Mofani oa thepa o sheba kamoo phofo e fetolang ntho e maling e bitsoang methemoglobin ho ba hemoglobin e tloaelehileng.

Ha ho boitokiso bo khethehileng bo hlokehang bakeng sa tlhahlobo ena.

Ha nale e kentsoe ho hula mali, batho ba bang ba utloa bohloko bo itekanetseng. Ba bang ba ikutloa feela ho hlaba kapa ho hlaba. Kamora moo, ho kanna ha ba le ho longoa kapa ho longoa hanyenyane. Haufinyane sena sea fela.


Ho na le mefuta e 'maloa ea liprotheine tse tsamaisang oksijene maling. E 'ngoe ea tsona ke methemoglobin. Tekanyo e tloaelehileng ea methemoglobin maling hangata e 1%. Haeba boemo bo phahame, o ka kula hobane protheine ha e na oksijene. Sena se ka etsa hore mali a hau a shebahale a le sootho ho fapana le a bofubelu.

Methemoglobinemia e na le lisosa tse 'maloa, tseo bongata ba tsona e leng liphatsa tsa lefutso (bothata ba liphatsa tsa hau tsa lefutso). Teko ena e sebelisetsoa ho khetholla phapang lipakeng tsa methemoglobinemia e bakoang ke khaello ea protheine e bitsoang cytochrome b5 reductase le mefuta e meng e fetisoang ke malapa (a futsitsoeng). Ngaka ea hau e tla sebelisa liphetho tsa tlhahlobo ena ho u thusa ho tseba kalafo ea hau.

Ka tloaelo, methylene blue e theola lebelo la methemoglobin maling kapele.

Mekhahlelo e tloaelehileng ea boleng e ka fapana hanyane hara lilaboratori tse fapaneng. Li-lab tse ling li sebelisa litekanyo tse fapaneng kapa li leka liteko tse fapaneng. Bua le mofani oa hau ka moelelo oa sephetho sa hau sa liteko.

U ka ba le mofuta o sa tloaelehang oa methemoglobinemia haeba tlhahlobo ena e sa theole mali a methemoglobin haholo.


Ha ho na kotsi e kholo ea ho nkuoa mali a hau. Methapo le methapo li fapana ka boholo ho tloha ho motho e mong ho ea ho o mong le ho tloha lehlakoreng le leng la 'mele ho ea ho le leng. Ho kenya IV ho ka ba thata ho uena kapa ho ngoana oa hau ho feta batho ba bang.

Likotsi tse ling tse amanang le mofuta ona oa tlhahlobo ea mali li nyane, empa li ka kenyelletsa:

  • Ho tsoa mali a mangata
  • Ho akheha kapa ho ikutloa o le hlooho e boima
  • Li-punctures tse ngata ho fumana methapo
  • Hematoma (mali a bokellanang ka tlasa letlalo a bakang matetetso)
  • Tšoaetso (kotsi e nyane neng kapa neng ha letlalo le robehile, empa menyetla ea tšoaetso e eketsa nako e telele IV e lula ka mothapong)
