Plasmapheresis: chii icho, zvinoitwa sei uye zvinogona kuitika matambudziko

Zvemukati

• Chii ichochi
• Zvinoitwa sei
• Zvinogona kuitika maplasmapheresis

Plasmapheresis imhando yekurapa inoshandiswa kunyanya kana paine zvirwere umo mune kuwedzera kwehuwandu hwezvinhu zvinogona kukuvadza hutano, senge mapuroteni, enzymes kana antibodies, semuenzaniso.

Nekudaro, plasmapheresis inogona kukurudzirwa pakurapa kweTrombotic Thrombocytopenic Purpura, Guillain-Barré Syndrome uye Myasthenia Gravis, chiri chirwere chemuviri chinoratidzirwa nekufambira mberi kwekurasikirwa kwemhasuru basa nekuda kwekugadzirwa kwe autoantibodies.

Maitiro aya anovavarira kubvisa izvo zvinhu zviripo muplasma kuburikidza neiyo filtration maitiro. Plasma inoenderana neinenge gumi muzana yeropa uye ine mapuroteni, glucose, zvicherwa, mahormone uye zvinogwamba, semuenzaniso. Dzidza zvakawanda nezve zvinoumba ropa uye mashandiro azvo.

Chii ichochi

Plasmapheresis maitiro anovavarira kusefa ropa, kubvisa izvo zvinhu zviripo muplasma uye kudzorera iyo plasma kumuviri pasina izvo zvinhu zviri kukonzera kana kuenderera chirwere.

Nekudaro, maitiro aya anoratidzwa ekurapa kwezvirwere zvinoitika nekuwedzera kwezvimwe zvikamu zveplasma, zvakadai semasoja ekudzivirira chirwere, albinin kana zvinogwamba, zvakadai se:

• Lupus;
• Myasthenia gravis;
• Akawanda myeloma;
• Waldenstrom's macroglobulinemia;
• Guillain-Barré chirwere;
• Multiple sclerosis;
• Thrombotic thrombocytopenic purpura (PTT);

Kunyangwe plasmapheresis iri kurapwa kwakanyanyisa pakurapa kwezvirwere izvi, zvakakosha kuti munhu arambe achirapa mushonga unoratidzwa nachiremba, sezvo mashandiro eiyi nzira isingatadzise kugadzirwa kwezvinhu zvine chekuita nechirwere ichi.

Ndokunge, mune zvechirwere che autoimmune, semuenzaniso, plasmapheresis inosimudzira kubviswa kweakawandisa autoantibodies, zvisinei kugadzirwa kwea antibodies hakuna kuoma mitezo, uye munhu wacho anofanira kushandisa mishonga yekuzvidzivirira sekutungamira kwachiremba.

Zvinoitwa sei

Plasmapheresis inoitwa pachishandiswa catheter inoiswa mune jugular kana yevakadzi turakiti uye chikamu chega chega chinotora avhareji yemaawa maviri, izvo zvinogona kuitwa zuva nezuva kana mamwe mazuva, sekuraira kwachiremba. Zvichienderana nechirwere chiri kurapwa, chiremba anogona kukurudzira zvimwe kana zvishoma zvikamu, nezvikamu zvinomwe zvinowanzo kuratidzwa.

Plasmapheresis kurapwa kwakafanana nehemodialysis, umo ropa remunhu rinobviswa uye plasma inopatsanurwa. Iyi plasma inoitwa mafirita, umo izvo zvinhu zviripo zvinobviswa uye iyo isina chinhu-plasma inodzoserwa mumuviri.

Maitiro aya, zvisinei, anosefa zvinhu zvese zvirimo muplasma, zvese zvinobatsira uye zvinokuvadza, uye nekudaro, huwandu hwezvinhu zvinobatsira hunotsiviwa nekushandisa bhegi replasma idzva rakapihwa kubhengi reropa rechipatara, kudzivirira matambudziko munhu.

Zvinogona kuitika maplasmapheresis

Plasmapheresis inzira yakachengeteka, asi senge chero imwe nzira inoparadza, ine njodzi, iyo huru iri:

• Kuumbwa kwehematoma panzvimbo yehutachiona hwekuwana;
• Njodzi yehutachiona panzvimbo ine venous yekuwana saiti;
• Ngozi yakakwira yekubuda ropa, nekuda kwekubviswa kweyekuvhara zvinhu zviripo mu plasma;
• Njodzi yekuchinja kweropa, senge semaitiro ekusagadzikana nemapuroteni aripo muplasma yakaiswa.

Nekudaro, kuve nechokwadi chekuti pane njodzi shoma yezvinetso, zvakakosha kuti maitiro aya aitirwe nehunyanzvi akadzidziswa uyo anoremekedza mamiriro ehutsanana ane chekuita nekuchengetedza murwere. Uye zvakare, zvakakosha kuti kuwedzerwa plasma nyowani kunoitwawo, nenzira iyi zvinokwanisika kuvimbisa kuti izvo zvinhu zvakakosha pakuita kwakanaka kwemuviri zviriwo muhuwandu hwakakwana.
