Matenda osiyanasiyana m'magazi ali ndi poizoni, zinthu zotupa, maselo a mavairasi ndi zina. Pochotsa iwo, plasmapheresis amagwiritsidwa ntchito - ubwino ndi kupweteka kwa kugwiritsa ntchito njirayi kumakambidwa mobwerezabwereza ku chipatala. Asayansi ena amaumirira kuti zopanda pake zilibe ntchito, pamene madokotala ena amapereka zifukwa zamphamvu kuti ziwathandize.
Njira zazikulu zopangira plasmapheresis ndi kusungunula (nembanemba) ndi mphamvu (manual, centrifugation).
Zochita ndi kupweteka kwa membrane plasmapheresis
Njira imeneyi yochitira ndondomekoyi imaphatikizapo kusungunuka kwa magazi mosalekeza muzipangizo zamakono - zopaka pulasitiki. Kupyolera mu catheter, kuikidwa mu mitsempha 1 kapena 2 ya wodwala, magazi amatengedwa. Amagwiritsa ntchito mafotolo omwe amathira plasma ndi poizoni ndi maselo ena osokoneza bongo. Kuyeretsa magazi kumasakanikirana ndi isotonic yankho ndipo nthawi yomweyo kubwerera ku magazi. Pulasitiki yowonongeka imasonkhanitsidwa mu thumba losiyana la polyethylene ndipo imachotsedwa.
Ubwino wa membrane plasmapheresis:
- chitetezo;
- Kukonzekera kwa thupi physically normal ntchito ya mtima pa gawo lonse;
- liwiro (njirayi imakhala pafupifupi ola limodzi);
- kusakhala ndi zowawa zosasangalatsa;
- Gwiritsani ntchito njira yokhayo ya isotonic (biocompatible) ndi magazi a munthu.
Palibe zoperewera zazikulu m'mapulmapheresis opangidwa bwino. Nthawi zambiri, wodwalayo amatha kumva chizungulire, kupweteka pang'ono kwa miyendo , kufooka kapena kunyowa. Zizindikiro izi zimatha msanga paokha.
Mapindu ndi mavitamini a plasmapheresis ndi centrifugation
Njira yogwiritsira ntchito njirayi imaphatikizapo kusonkhanitsa kwa magazi, komwe kumayeretsedwa ndi mchere wambiri ndi antiticoagulants (plasmapheresis yachangu) kapena centrifugation mu firiji.
Chinthu chokhacho cha pulogalamuyi ndi zotsatira zofanana ndi njira ya membrane. Ndipo kuipa kwa mavitamini plasmapheresis ndi kwakukulu kwambiri:
- ndondomeko imatenga nthawi yaitali;
- sizingatheke kuti nthawi yomweyo muyeretse buku lalikulu la plasma;
- Pambuyo pazitsanzo za magazi m'pofunikira kuti mudziwe mankhwala osokoneza bongo kapena mankhwala osokoneza bongo;
- kumafuna magawo ambiri.
Ndikofunika kuzindikira kuti ubwino ndi chiopsezo cha mtundu uliwonse wa plasmapheresis ayenera kuyamba kukambirana ndi dokotala. Imeneyi ndi njira yaikulu yachipatala yomwe imachitika pamaso pa ziwonetsero zomveka, osati njira yokonzera magazi .
