Intshayelelo
Kulawulo lwesifo sezintso esikwinqanaba lokugqibela (ESRD) kunye nokulimala kwezintso okukhawulezileyo (AKI),idayaliza—edla ngokubizwa ngokuba “zintso zokwenziwa”—yintliziyo engundoqoisixhobo sezonyangookususa ubuthi kunye nolwelo olugqithisileyo egazini. Ichaphazela ngokuthe ngqo ukusebenza kakuhle konyango, iziphumo zesigulana, kunye nomgangatho wobomi. Kubanikezeli beenkonzo zempilo, ukukhetha i-dialyzer efanelekileyo kukulinganisela phakathi kweenjongo zonyango, ukhuseleko lwesigulana, kunye neendleko. Kwizigulana kunye neentsapho, ukuqonda umahluko phakathi kweentlobo ze-dialyzer kubanceda bathathe inxaxheba ekwenzeni izigqibo kunye.
Eli nqaku lichaza iindidi eziphambili zee-dialyzers, iimpawu zazo zobugcisa, kunye namaqhinga okukhetha asebenzayo asekelwe kwizikhokelo zanamhlanje ezifana ne-KDIGO.
Ulwahlulo oluPhambili lweeDialyzers
Ii-dialyzers ze-hemodialysis zanamhlanje zinokuhlulwahlulwa ngokwemilinganiselo emine ephambili: izinto ze-membrane, uyilo lwesakhiwo, iimpawu zokusebenza, kunye nezinto eziqwalaselwa ngumguli.
1. Ngezinto zeMembrane: Zendalo vs. Zenziweyo
Iinwebu ezisekwe kwi-cellulose (zendalo)
Zenziwe ngokwesiko ngee-cellulose derivatives ezifana ne-cuprophane okanye i-cellulose acetate, ezi membrane zibiza kancinci kwaye zifumaneka ngokubanzi. Nangona kunjalo, azinazo ii-biocompatibility ezilinganiselweyo, zinokubangela ukusebenza kwe-complement, kwaye zinokubangela umkhuhlane okanye i-hypotension ngexesha le-dialysis.
IiNkumba ezenziwe ngobuchule (ezisebenza kakuhle)
Yenziwe ngeepolymers ezikumgangatho ophezulu ezifana ne-polysulfone (PSu), i-polyacrylonitrile (PAN), okanye i-polymethyl methacrylate (PMMA). Ezi membrane zibonelela ngobukhulu be-pore elawulwayo, ukususwa okuphezulu kwe-molecule ephakathi, kunye nokuhambelana okuphezulu kwezinto eziphilayo, ukunciphisa ukudumba kunye nokuphucula ukunyamezela kwezigulane.
2. NguYilo lweSakhiwo: I-Hollow Fiber vs. Flat Plate
IiDialyzer zeFiber ezingenanto(≥90% yokusetyenziswa kweklinikhi)
Iqulethe amawaka ee-capillary fibers ezintle ezinomphezulu omkhulu (1.3–2.5 m²) kunye nomthamo ophantsi wokuzilungiselela (<100 mL). Zibonelela ngokucoceka okuphezulu ngelixa zigcina ukuhamba kwegazi okuzinzileyo.
IiDayalizi zePlate eSicaba
Azisetyenziswa rhoqo namhlanje, ezi zineendawo ezincinci ze-membrane (0.8–1.2 m²) kunye nomthamo ophezulu we-priming. Zigcinelwe iinkqubo ezikhethekileyo ezifana nokutshintshiselana kwe-plasma kunye ne-dialysis.
3. Ngokweempawu zokusebenza: I-Flux ephantsi vs. I-Flux ephezulu vs. I-HDF-Optimized
IiDialyzers zeFlux eziphantsi (LFHD)
I-Ultrafiltration coefficient (Kuf) <15 mL/(h·mmHg). Ngokuyintloko susa izinto ezincinci ezinyibilikayo (urea, creatinine) ngokusasazeka. Ixabiso layo liphantsi, kodwa ine-middle-molecule clearance encinci (β2-microglobulin <30%).
IiDialyzers zeFlux ephezulu (HFHD)
I-Kuf ≥15 mL/(h·mmHg). Vumela ukususwa kweemolekyuli ezinkulu ngendlela eguquguqukayo, kunciphisa iingxaki ezifana ne-dialysis-related amyloidosis kunye nokuphucula iziphumo zentliziyo.
IiDialyzers ezithile zeHemodiafiltration (HDF)
Yenzelwe ukususwa kwetyhefu ekwi-molecule ephakathi kunye ne-protein-bound toxin, idla ngokudibanisa ii-membranes zokwenziwa ezikwaziyo ukungena ngokukhawuleza kunye nee-adsorption layers (umz., ii-activated carbon coatings).
4. Ngokweprofayili yesigulana: Umntu omdala, umntwana, ukhathalelo olubalulekileyo
Iimodeli eziQhelekileyo zabantu abadala: ii-membranes eziyi-1.3–2.0 m² kuninzi lwezigulane zabantu abadala.
Iimodeli zabantwana: ii-membranes eziyi-0.5–1.0 m² ezinomthamo ophantsi wokuzilungiselela (<50 mL) ukuze kuthintelwe ukungazinzi kwe-hemodynamic.
Iimodeli zoNyango oluBalulekileyo: Iingubo ezithintela ukugabha kwegazi kunye nomthamo ophantsi kakhulu wokugabha igazi (<80 mL) wonyango oluqhubekayo lokutshintshwa kwezintso (CRRT) kwizigulana ze-ICU.
