Mitundu ya Dialyzer ndi Kusankha Kwachipatala: Buku Lokwanira

Chiyambi

Poyang'anira matenda a impso otsiriza (ESRD) ndi kuvulala kwa impso mwadzidzidzi (AKI),choyezera dializa—nthawi zambiri amatchedwa “impso yopangira”—ndiye mazikochipangizo chachipatalazomwe zimachotsa poizoni ndi madzi ochulukirapo m'magazi. Zimakhudza mwachindunji magwiridwe antchito a chithandizo, zotsatira za wodwala, komanso moyo wabwino. Kwa opereka chithandizo chamankhwala, kusankha chida choyenera cha dialyzer ndi mgwirizano pakati pa zolinga zachipatala, chitetezo cha wodwala, ndi mtengo wake. Kwa odwala ndi mabanja, kumvetsetsa kusiyana pakati pa mitundu ya dialyzer kumawathandiza kutenga nawo mbali popanga zisankho zofanana.

Nkhaniyi ikufotokoza magulu akuluakulu a ma dialyzer, luso lawo, ndi njira zothandiza zosankhira pogwiritsa ntchito malangizo amakono monga KDIGO.

Kugawa Magulu Aakulu a Ma Dialyzer

Ma dialyzer amakono a hemodialysis amatha kugawidwa m'magulu anayi akuluakulu: zinthu za nembanemba, kapangidwe ka kapangidwe kake, makhalidwe a ntchito, ndi zinthu zomwe wodwala amaganizira.

1. Ndi Zida za Membrane: Zachilengedwe vs. Zopangidwa

Ma nembanemba Ochokera ku Cellulose (Achilengedwe)
Zopangidwa mwachikhalidwe kuchokera ku zinthu zopangidwa ndi cellulose monga cuprophane kapena cellulose acetate, ma nembanemba awa ndi otsika mtengo ndipo amapezeka kwambiri. Komabe, ali ndi biocompatibility yochepa, angayambitse kuyambika kwa complement, ndipo angayambitse malungo kapena hypotension panthawi ya dialysis.

Ma nembanemba Opangidwa (Ogwira Ntchito Kwambiri)
Yopangidwa ndi ma polima apamwamba kwambiri monga polysulfone (PSu), polyacrylonitrile (PAN), kapena polymethyl methacrylate (PMMA). Ma nembanemba awa amapereka kukula kwa ma pore olamulidwa, kutseguka kwapakati kwa mamolekyulu, komanso kuyanjana kwabwino kwa biochemical, kuchepetsa kutupa ndikuwonjezera kulolerana kwa odwala.

2. Ndi Kapangidwe ka Kapangidwe: Ulusi Wopanda Chingwe vs. Mbale Yathyathyathya

Zoyezera Ulusi Wopanda Chopondapo(≥90% ya momwe amagwiritsidwira ntchito kuchipatala)
Muli ulusi wa capillary wambirimbiri wokhala ndi malo akuluakulu (1.3–2.5 m²) komanso mphamvu yochepa yopangira madzi (<100 mL). Amapereka mpweya wabwino kwambiri komanso kusunga kayendedwe ka magazi kokhazikika.

Zoyezera Ma Dialyzer a Flat Plate
Masiku ano, izi sizigwiritsidwa ntchito kawirikawiri, zili ndi malo ang'onoang'ono a nembanemba (0.8–1.2 m²) komanso ma priming voliyumu apamwamba. Zimasungidwa kuti zigwiritsidwe ntchito mwapadera monga kuphatikizana kwa plasma ndi dialysis.

3. Ndi Makhalidwe Ogwira Ntchito: Kutsika Kwambiri poyerekeza ndi Kutsika Kwambiri poyerekeza ndi Kukhazikika kwa HDF

Ma Dialyzer Otsika a Flux (LFHD)
Choyezera cha Ultrafiltration (Kuf) <15 mL/(h·mmHg). Choyamba, chotsani zinthu zazing'ono zosungunulira (urea, creatinine) kudzera mu kufalikira. Zotsika mtengo, koma ndi clearance yochepa ya mamolekyulu apakati (β2-microglobulin <30%).

Ma Dialyzer Othamanga Kwambiri (HFHD)
Kuf ≥15 mL/(h·mmHg). Lolani kuti mamolekyu akuluakulu atuluke mosavuta, kuchepetsa mavuto monga amyloidosis yokhudzana ndi dialysis komanso kukonza zotsatira za mtima ndi mitsempha yamagazi.

Ma Dialyzer Odziwikiratu a Hemodiafiltration (HDF)
Yopangidwira kuchotsa poizoni wapakati pa molekyulu ndi mapuloteni ambiri, nthawi zambiri kuphatikiza ma nembanemba opangidwa omwe amatha kulowa mosavuta ndi zigawo zolowetsa madzi (monga, zokutira za kaboni zoyambitsidwa).

4. Mbiri ya Wodwala: Wamkulu, Ana, Chisamaliro Chofunikira

Ma Model Okhazikika a Akuluakulu: Nembanemba ya 1.3–2.0 m² kwa odwala ambiri akuluakulu.

Ma Model a Ana: 0.5–1.0 m² nembanemba yokhala ndi priming voliyumu yochepa (<50 mL) kuti apewe kusakhazikika kwa hemodynamic.

Zitsanzo Zosamalira Odwala Odwala: Zophimba zoletsa magazi kutuluka magazi ndi voliyumu yotsika kwambiri (<80 mL) ya chithandizo chokhazikika cha impso (CRRT) mwa odwala a ICU.

Dziwani Zambiri Zokhudza Mitundu Yaikulu ya Dialyzer

Maselo achilengedwe a Cellulose

Zinthu zake: Zotsika mtengo, zokhazikika bwino, koma sizigwirizana ndi thupi; chiopsezo chachikulu cha kutupa.

Kugwiritsa Ntchito Pachipatala: Koyenera chithandizo cha kanthawi kochepa kapena m'malo omwe mtengo wake ndi womwe umakhala wofunika kwambiri.

Ma nembanemba Ogwira Ntchito Kwambiri

Polysulfone (PSu): Chipangizo chodziwika bwino cha dialyzer chokhala ndi flux yambiri, chomwe chimagwiritsidwa ntchito kwambiri mu hemodialysis yothamanga kwambiri komanso HDF.

Polyacrylonitrile (PAN): Imadziwika kuti imayamwa kwambiri poizoni womangika ndi mapuloteni; imathandiza kwa odwala omwe ali ndi hyperuricemia.

Polymethyl Methacrylate (PMMA): Kuchotsa bwino mankhwala osungunuka m'thupi m'maselo akuluakulu, nthawi zambiri amagwiritsidwa ntchito pa matenda a impso a shuga kapena matenda a mafupa ndi mchere.

Kufananiza Kusankha kwa Dialyzer ndi Zochitika Zachipatala

Chitsanzo 1: Kukonza Hemodialysis mu ESRD

Zoyenera: Chojambulira chopangidwa ndi flux yapamwamba (monga PSu).

Chifukwa: Maphunziro a nthawi yayitali ndi malangizo a KDIGO amathandizira kuti ma nembanemba azikhala ndi mphamvu zambiri kuti pakhale zotsatira zabwino za mtima ndi kagayidwe kachakudya.

Chitsanzo Chachiwiri: Chithandizo cha Kuvulala Kwambiri kwa Impso (AKI)

Zoyenera: Cellulose yotsika kapena dialyzer yopangidwa ndi ndalama zochepa.

Chifukwa: Chithandizo cha kanthawi kochepa chimayang'ana kwambiri pakuchotsa madzi m'thupi ndi kuyeretsa bwino; kugwiritsa ntchito bwino ndalama ndikofunikira.

Chosiyana: Mu sepsis kapena kutupa kwa AKI, ganizirani zoyezera mpweya wambiri kuti muchotse cytokine.

Chitsanzo Chachitatu: Kuyeretsa Magazi Pakhomo (HHD)

Zoyenera: Chojambulira cha ulusi wopanda kanthu chokhala ndi malo ang'onoang'ono okhala ndi priming yokha.

Chifukwa: Kukhazikitsa kosavuta, kufunikira kwa magazi ochepa, komanso chitetezo chabwino m'malo odzisamalira.

Chitsanzo 4: Kuyeretsa magazi kwa ana

Zoyenera: Zoyeretsera zoyeretsera zopangidwa zopangidwa ndi anthu ochepa, zomwe zimagwirizana ndi chilengedwe (monga PMMA).

Chifukwa: Kuchepetsa kupsinjika kwa kutupa ndi kusunga kukhazikika kwa hemodynamic panthawi yomera.

Chitsanzo 5: Odwala a ICU Odwala Kwambiri (CRRT)

Zoyenera: Ma dialyzer opangidwa ndi anticoagulant, otsika voliyumu, omwe amapangidwira chithandizo chopitilira.

Chifukwa: Amachepetsa chiopsezo cha kutuluka magazi pamene akusunga njira yothandiza yochotsera magazi mwa odwala osakhazikika.

Zochitika Zamtsogolo mu Ukadaulo wa Dialyzer

Kugwirizana kwabwino kwa thupi: Ma nembanemba opanda endotoxin ndi zokutira za endothelial zomwe zimapangidwa ndi bio kuti achepetse kutupa ndi zoopsa zotsekeka kwa magazi.

Smart Dialyzers: Kuwunika kolowera mkati mwa intaneti komanso kuwongolera kochokera ku algorithm yoletsa magazi kuundana kuti mugwiritse ntchito bwino nthawi yeniyeni.

Impso Zopangidwa Zovalidwa: Ma nembanemba osinthika a ulusi woboola omwe amalola dialysis kunyamulika, maola 24 kuti wodwala azitha kuyenda.

Zipangizo Zosamalira Kuteteza Kuchilengedwe: Kupanga nembanemba zomwe zimawola (monga polylactic acid) kuti zichepetse zinyalala zachipatala.

Mapeto

Kusankha chida choyezera magazi m'thupi (hemodialysis dialyzer) si chisankho chaukadaulo chokha—ndi kuphatikiza mkhalidwe wa wodwala, zolinga za chithandizo, komanso kuganizira zachuma. Odwala a ESRD amapindula kwambiri ndi zida zoyezera magazi m'thupi zomwe zimathamanga kwambiri kuti achepetse mavuto a nthawi yayitali. Odwala a AKI amatha kusankha mtengo ndi kuphweka. Ana ndi odwala omwe ali ndi matenda ofunikira amafunika zida zokonzedwa bwino. Pamene luso likupita patsogolo, zida zoyezera magazi m'mawa zidzakhala zanzeru, zotetezeka, komanso zoyandikana ndi ntchito yachilengedwe ya impso—kukweza moyo ndi moyo wabwino.
