Pazvirwere zvakasiyana-siyana muropa pane zvinhu zvinosvibisa, zvinokonzera kupisa, masero ezvirwere nezvimwe zvivako zvepabonde. Kuti uzvibvise, plasmapheresis inoshandiswa - zvinobudirira uye nhamo yekushandisa nzira iyi zvinogara zvichikurukurwa munharaunda yezvokurapa. Vamwe masayendisiti vanomiririra kusabatsiri kwekombiyuta iyi, apo vamwe vanachiremba vanopa nharo dzakasimba mukuda kwekubudirira kwayo.
Iyo nzira huru yekuita plasmapheresis inosvina (membrane) uye inokonzera (bhuku, centrifugation).
Pros uye hutano hwe membrane plasmapheresis
Iyi nzira yekuita iyo nzira inotora kuendesa kushandiswa kweropa mune zvigadzirwa zvakasiyana-plasti filters. Kuburikidza ne catheter, yakagadzirirwa mune 1 kana 2 mapupa emurwere, ropa rinotorwa. Iyo inomhanya kuburikidza nemafuta ekudzivirira anogadzika plasma ane chepfu uye mamwe masero anorwara. Kunatswa ropa rinosanganiswa ne isotonic solution uye rinodzokera zvakare kuropa rega. Iyo plasma yakasanganiswa inounganidzwa mune imwe saga ye polyethylene uye inobviswa.
Kubatsirwa kwemuviri memaplasmapheresis:
- kuchengeteka;
- kugadziriswa kwehupenyu hwehupenyu hwepanyama panguva yose yerongwa;
- kukurumidza (iyo nzira inotora nguva inenge awa);
- kusavapo kwekunzwa kusingafadzi;
- Shandisa chete isotonic solution (biocompatible) uye ine ropa revanhu.
Izvo hazvina kushaya kukwana kwakakonzerwa nemaaplasmapheresis. Muzviitiko zvisingawanzoitiki, murwere angave ane ruzivo, kunetseka kwemaviko, kushaya simba kana kunetseka. Zviratidzo izvi zvinokurumidza kupera pachavo pachavo.
Pros uye zvinotapira plasmapheresis uye centrifugation
Izvo zvinogadzirisa nzira yehutano zvinosanganisira kuunganidza ropa, iyo inonatswa nekugadziriswa mumidziyo ne anticoagulants (plasmapheresis bhuku) kana kuti centrifugation mufiriji.
Iyo chete inobatsira yekombiyuta iyi ndiyo inokanganisa yakafanana neyemagetsi nzira. Uye kusagadzikana kwekugadzirisa plasmapheresis kwakawanda zvikuru:
- iyo inotora nguva refu;
- hazvibviri kuchenesa kamwechete guru re plasma;
- mushure mokunge ropa rakataridzirwa zvakakosha kuunza maitiro ekuisa ropa kana kuti mishonga yemupiro;
- inoda nguva dzakawanda.
Zvakakosha kucherechedza kuti zvinobudirira uye zvakanakira zvepi zvimwe zvakasiyana zve plasmapheresis zvinofanira kutanga zvakurukurwa nachiremba. Iyi ndiyo chirongwa chakakomba chezvechirwere chakaitwa pamberi pezviratidzo zvakajeka, uye kwete nzira yekuchenesa ropa .
