Kupu Whakataki
I roto i te whakahaere i te mate whatukuhu wāhanga whakamutunga (ESRD) me te whara whatukuhu whakapeka (AKI), ko temīhini tātari toto—e kiia ana ko te "whatukuhu horihori"—koinei te uhotaputapu hauorae tango ana i ngā paitini me te wai nui i roto i te toto. Ka pā tika ki te whai huatanga o te maimoatanga, ngā putanga o te tūroro, me te kounga o te oranga. Mō ngā kaiwhakarato hauora, ko te whiriwhiri i te dialyzer tika he taurite i waenga i ngā whāinga haumanu, te haumaru o te tūroro, me te utu. Mō ngā tūroro me ngā whānau, ko te mārama ki ngā rerekētanga i waenga i ngā momo dialyzer ka āwhina i a rātou ki te whai wāhi ki te whakatau tahi.
Ka wetewetehia e tēnei tuhinga ngā kāwai matua o ngā dialyzer, ō rātou āhuatanga hangarau, me ngā rautaki whiriwhiri mahi e ahu mai ana i ngā aratohu hou pēnei i a KDIGO.
Te Whakarōpūtanga Matua o ngā Dialyzers
E whā ngā āhuatanga matua o ngā taputapu dialysis hou: te rauemi o te membrane, te hoahoa hanganga, ngā āhuatanga mahi, me ngā whakaaro motuhake ki te tūroro.
1. Mā te Rauemi Kiriuhi: Taiao vs. Hanganga
Ngā kiriuhi (taiao) e hangai ana ki te cellulose
He mea hanga mai i ngā matū cellulose pēnei i te cuprophane, te cellulose acetate rānei, he iti te utu, ā, he whānui te wātea o ēnei kiriuhi. Heoi, he iti noa te hototahitanga ki te koiora, ka taea te whakaoho i te whakahohenga o ngā tāpiringa, ā, ka pāngia pea e te kirika, te whakaheke toto rānei i te wā o te dialysis.
Ngā Kiriuhi Hanga (Mahinga-Teitei)
He mea tito mai i ngā pūmua kounga teitei pērā i te polysulfone (PSu), te polyacrylonitrile (PAN), te polymethyl methacrylate (PMMA) rānei. Ka tukuna e ēnei kiriuhi he rahi o ngā pore kua whakahaeretia, he nui ake te whakawātea i te ngota waenga, me te hototahitanga pai ake, ka whakaiti i te mumura me te whakapai ake i te manawanui o te tūroro.
2. Mā te Hoahoa Hanganga: Muka Kohao vs. Pereti Papatahi
Ngā Dialyzer muka tuwhera(≥90% o te whakamahinga haumanu)
Kei roto ngā mano tini o ngā muka capillary angiangi me te horahanga mata nui (1.3–2.5 m²) me te iti o te rōrahi whakatō (<100 mL). Ka whakaratohia e rātou he whakawāteatanga tino whai hua me te pupuri tonu i te rere o te toto pumau.
Ngā Dialyzer Pereti Papatahi
He onge te whakamahinga o ēnei i ēnei rā, he iti ake ngā wāhi kiriuhi (0.8–1.2 m²) me ngā rahinga whakapūmau nui ake. He mea rāhui ēnei mō ngā tikanga motuhake pēnei i te whakawhiti plasma me te dialysis.
3. Mā ngā Āhuatanga Mahi: Rerenga Iti vs. Rerenga Teitei vs. HDF-Arotau
Ngā Dialyzer Rere Iti (LFHD)
Tauwehenga tātaritanga-rahi (Kuf) <15 mL/(h·mmHg). Tangohia ngā matū iti (urea, creatinine) mā te tohatoha. He iti te utu, engari he iti noa te whakakorenga o te ngota waenga (β2-microglobulin <30%).
Ngā Dialyzer Rere Teitei (HFHD)
Kuf ≥15 mL/(h·mmHg). Tukua te whakakorenga convective o ngā ngota nui ake, ka whakaiti i ngā raruraru pēnei i te amyloidosis e pā ana ki te dialysis me te whakapai ake i ngā putanga cardiovascular.
Ngā Dialyzers Motuhake mō te Hemodiafiltration (HDF)
I hangaia mō te tango i te paitini waenga-ngota me te paitini here-pūmua, he maha ngā wā ka whakakotahi i ngā kiriuhi hangai uruhanga-teitei me ngā paparanga mimiti (hei tauira, ngā paninga waro whakahohe).
4. Mā te Kōtaha Tūroro: Pakeke, Tamariki, Manaaki Tino Pai
Ngā Tauira Pakeke Paerewa: 1.3–2.0 m² ngā kiriuhi mō te nuinga o ngā tūroro pakeke.
Tauira Tamariki: 0.5–1.0 m² ngā kiriuhi me te iti o te rōrahi whakapūmau (<50 mL) hei karo i te kore pumau o te toto.
Ngā Tauira Tiaki Tino Hira: Ngā paninga ārai toto me te iti rawa o te rahinga whakatō (<80 mL) mō te whakaora whakakapinga whatukuhu tonu (CRRT) i ngā tūroro ICU.
Ruku Hōhonu ki ngā Momo Matua o te Dialyzer
Ngā kiriuhi pūtau taiao
Ngā Āhuatanga: He utu whaitake, kua roa e whakamahia ana, engari kāore i te tino hototahi ki ngā āhuatanga koiora; he nui ake te mōrearea o ngā tauhohenga mumura.
Whakamahinga Hauora: He pai mō te tautoko wā poto, mō ngā wāhi rānei e aro nui ana ki te utu.
Ngā Kiriuhi Mahi-Teitei Hangahanga
Polysulfone (PSu): He rauemi dialyzer rere nui noa iho, e whakamahia whānuitia ana i roto i te hemodialysis rere nui me te HDF.
Polyacrylonitrile (PAN): E mōhiotia ana mō te kaha o te mimiti o ngā paitini e herea ana ki te pūmua; he mea whai hua mō ngā tūroro e pāngia ana e te hyperuricemia.
Polymethyl Methacrylate (PMMA): Te tango i te matū matūriki taurite puta noa i ngā rahi ngota ngota, e whakamahia ana i roto i ngā mate tākihi mate huka, i ngā mate wheua-kohuke rānei.
Te Whakataurite i te Kōwhiringa Dialyzer ki ngā Horopaki Hauora
Horopaki 1: Hemodialysis Tiaki i roto i te ESRD
E taunakitia ana: He mīhini tātari wairewa teitei (hei tauira, PSu).
Pūtake: E tautoko ana ngā rangahau roa me ngā aratohu a KDIGO i ngā kiriuhi rere-rahi mō ngā putanga pai ake o te ngakau me te pākia o te tinana.
Horopaki 2: Tautoko mō te Whara Whatukuhu Whakapeka (AKI)
E taunakitia ana: He cellulose iti te rere, he dialyzer hangai utu iti rānei.
Whakamārama: Ko te rongoā wā poto e arotahi ana ki te whakakorenga o ngā matū iti me te taurite o ngā wai; ko te whai huatanga o te utu te mea nui.
Okotahi: Mō te sepsis, te mumura rānei o te AKI, whakaarohia ngā dialyzers tere-rerenga hei tango i te cytokine.
Horopaki 3: Hemodialysis Kāinga (HHD)
E taunakitia ana: He mīhini tātari muka tuwhera, he iti te mata, me te whakapūmau aunoa.
Pūtake: He māmā ake te whakatakotoranga, he iti ake te hiahia mō te nui o te toto, ā, he pai ake te haumaru mō ngā taiao tiaki-whaiaro.
Horopaki 4: Hemodialysis Tamariki
E taunakitia ana: Ngā dialyzer hangai iti-rahi kua whakaritea, hototahi ki te koiora (hei tauira, PMMA).
Pūtake: Te whakaiti i te ahotea mumura me te pupuri i te pumau o te toto i te wā e tipu ana.
Horopaki 5: Ngā Tūroro ICU Tino Mate (CRRT)
E taunakitia ana: Ngā dialyzer hangai kua pania ki te rongoā ārai toto, he iti te rahinga, i hangaia mō te rongoā tonu.
Pūtake: Ka whakaiti i te mōrearea o te toto me te pupuri tonu i te whakawātea whai hua i roto i ngā tūroro kāore i te pumau.
Ngā Auahatanga o te Hangarau Dialyzer ā-Mārama
Whakapai ake i te Hototahitanga Koiora: Ngā kiriuhi kore-endotoxin me ngā paninga endothelial i ahu mai i te koiora hei whakaiti i te mōrearea o te mumura me te toto totoka.
Ngā Dialyzer Atamai: Te aroturukitanga whakawātea ipurangi me te whakahaere ārai toto e hangai ana ki te raupaparorohiko mō te arotautanga rongoā wā-tūturu.
Ngā Whatukuhu Horihori Ka Taea te Mau: Ngā kiriuhi muka tuwhera ngāwari e taea ai te dialysis kawe, 24-hāora te nekenekehanga mō te tūroro.
Ngā Rauemi Hoa-Taiao: Te whakawhanaketanga o ngā kiriuhi pirau (hei tauira, te waikawa polylactic) hei whakaiti i ngā para hauora.
Whakamutunga
Ehara i te mea he whakatau hangarau noa iho te whiriwhiri i tētahi taputapu dialyzer hemodialysis—he whakaurunga o te āhua o te tūroro, ngā whāinga maimoatanga, me ngā whakaaro ōhanga. Ko ngā tūroro ESRD te hunga e tino whai hua ana mai i ngā taputapu dialyzer tere-rahi hei whakaiti i ngā raruraru mō te wā roa. Tērā pea ka aro nui ngā tūroro AKI ki te utu me te ngāwari. Me whai taputapu kua whakaritea pai mō ngā tamariki me ngā tūroro tiaki nui. I te whanaketanga o te auahatanga, ka mōhio ake, ka haumaru ake, ka tata ake hoki ngā taputapu dialyzer o āpōpō ki te mahi tūturu o te tākihi—ka whakapai ake i te oranga me te kounga o te oranga.
