Kuchenesa Ropa Chete Hemodialysis?

Munyaya yezveutano zvemazuva ano, izwi rekuti 'kucheneswa kweropa' rinowanzounza mupfungwa mifananidzo yevarwere vakapinzwa mumichina muchipatara, vachiitwa izvo zvinozivikanwa sehemodialysis. Zvisinei, kucheneswa kweropa ipfungwa yakafara zvikuru inobatanidza nzira dzakasiyana-siyana uye maitirwo, chimwe nechimwe chine chinangwa chayo chakasiyana uye kushandiswa.

Kutanga, ngatijekese kuti hemodialysis chii. Hemodialysis inzira inoshandiswa kunyanya kune varwere vane kutadza kweitsvo kwakanyanya. Mukuita uku, ropa remurwere rinotenderedzwa nemuchina unonzi dialyzer. Iyo dialyzer ine semipermeable membrane inosefa zvinhu zvinoraswa, yakawandisa mvura, uye chepfu kubva muropa. Ropa rakacheneswa iri rinobva radzorerwa mumuviri womurwere. Hemodialysis inowanzoitwa kakawanda pasvondo uye kurapwa kunoponesa hupenyu kune vanhu vazhinji vane chirwere chekupedzisira chetsvo.

Asi kucheneswa kweropa kunongopfuura chete hemodialysis. Imwe nzira yakadaro ndeye plasmapheresis. Plasmapheresis inosanganisira kupatsanura plasma kubva kumasero eropa. Plasma, ine masoja ekudzivirira chirwere, chepfu, nezvimwe zvinhu zvinokuvadza, inobviswa yotsiviwa neplasma itsva kana chinotsiva plasma. Iyi nzira inoshandiswa mukurapa kwakasiyana-siyana autoimmune kusagadzikana, senge Guillain-Barré syndrome, myasthenia gravis, uye lupus. Nekubvisa masoja ekudzivirira chirwere uye zvinhu kubva muplasma, plasmapheresis inogona kubatsira kuderedza kuzvimba nekuvandudza mamiriro emurwere.

Imwe nzira yekuchenesa ropa ndeye hemoperfusion. Muhemoperfusion, ropa remurwere rinopfuura nemukoramu izere neadsorbent zvinhu, zvakaita semarasha akabatidzwa kana resin. Nyaya iyi inosunga uye inobvisa chepfu nemishonga kubva muropa. Hemoperfusion inowanzoshandiswa muzviitiko zvekudarika zvinodhaka kana chepfu, sezvo inogona kukurumidza kubvisa zvinhu zvinokuvadza kubva muropa.

Kozoita continuous renal replacement therapy (CRRT). CRRT inzira yekuchenesa ropa iyo inoshandiswa muvarwere vanorwara zvakanyanya vane kukuvara kwakanyanya kweitsvo kana mamwe mamiriro anoda kuramba achibviswa kwetsvina uye mvura. Kusiyana nehemodialysis, iyo inoitwa muzvikamu zvakasiyana, CRRT inzira inoenderera inogona kumhanya kwemaawa kana mazuva. Izvi zvinobvumira kuwedzera kunyoro uye kugadzikana kubviswa kwemarara uye mvura, iyo inonyanya kukosha kune varwere vane hemodynamically kusagadzikana.

Pamusoro pemaitiro aya chaiwo, kune zvakare ari kubuda matekinoroji mumunda wekuchenesa ropa. Somuenzaniso, vamwe vatsvakurudzi vari kuongorora kushandiswa kwenanotechnology kugadzira nzira dzinoshanda uye dzakanangidzirwa dzekuchenesa ropa. Nanoparticles inogona kugadzirwa kuti inyatso kusunga uye kubvisa imwe chepfu kana utachiona kubva muropa, ichipa nzira yakasarudzika yekuchenesa ropa.

Zvakakosha kuziva kuti kunyange zvazvo nzira dzokuchenesa ropa dzichigona kunyatsoshanda pakurapa mamwe mamiriro ezvinhu, dzinouyawo nenjodzi. Zvinetso zvinogona kusanganisira kubuda ropa, utachiona, kusawirirana neropa, uye kuchinja kweBP. Naizvozvo, maitiro aya anowanzoitwa pasi pekutariswa kwepedyo kwevashandi vakadzidziswa zvehutano.

Mukupedzisa, kucheneswa kweropa ibasa rakaoma uye rakasiyana rinosanganisira zvakawanda kupfuura kungoita hemodialysis. Kubva kuplasmapheresis uye hemoperfusion kusvika kuCRRT uye teknolojia inobuda, kune nzira dzakasiyana-siyana dzinowanikwa kubatsira kubvisa zvinhu zvinokuvadza kubva muropa nekuvandudza hutano hwevarwere. Sezvo tsvakurudzo munharaunda iyi iri kuramba ichifambira mberi, tinogona kutarisira kuona dzimwe nzira itsva uye dzinoshanda dzekuchenesa ropa mune ramangwana, zvichipa tariro kune avo vanotambura nehupamhi hwezvirwere nemamiriro ezvinhu.
