Hemodialysis
Hemodialysis, tseem hu ua lub raum dag lossis lim ntshav, yog cov thev naus laus zis thev naus laus zis. Nws siv lub hauv paus ntsiab lus ntawm semipermeable daim nyias nyias los tshem tawm ntau yam teeb meem thiab ntau dhau cov khoom pov tseg thiab cov khoom siv hluav taws xob ntau dhau ntawm lub cev los ntawm kev sib kis, yog li ua kom huv cov ntshav thiab kho cov dej, electrolyte, thiab acid -base imbalances. [1] Lub semipermeable membrane siv hauv hemodialysis yog 10-20 micrometers tuab, nrog qhov nruab nrab qhov pore loj ntawm 3 nanometers. Yog li ntawd, nws tsuas yog tso cai rau me me molecules nrog ib tug molecular hnyav ntawm tsawg tshaj li 15,000 thiab ib co medium-qhov loj qhov me molecules hla mus, thaum loj molecules nrog ib tug molecular hnyav dua 35,000 tsis tuaj yeem hla. Yog li, cov proteins, pyrogens, kab mob, kab mob, thiab cov qe ntshav tsis tuaj yeem hla. Cov zis feem ntau yog dej, thiab hloov lub raum nrog lub raum dag, cov dej ntau yuav tsum tau tawm ntawm cov ntshav. Lub raum khoom siv tsuas tuaj yeem siv osmotic siab thiab ultrafiltration siab kom tshem tawm cov dej ntau dhau. Lub raum dag siv, piv txwv li, cov cuab yeej hemodialysis, txhua yam muaj cov haujlwm no, yog li tswj hwm cov ntshav zoo thiab kom muaj nuj nqis kom ze rau lub xeev lub cev.
Peritoneal Dialysis
Peritoneal dialysis siv lub peritoneum ua ib tug semi-permeable membrane. Lub ntiajteb txawj nqus quab yuam cov dialysate npaj rau hauv tus neeg mob lub peritoneal kab noj hniav los ntawm ib tug catheter. Qhov no tsim cov concentration gradient ntawm solutes thoob plaws lub peritoneum, ua rau cov kuab tshuaj nrog ntau dua concentrations txav mus rau qis concentrations (diffusion); dej txav ntawm sab hypotonic mus rau sab hypertonic (osmosis). Los ntawm kev hloov pauv peritoneal dialysate tsis tu ncua, cov khoom lag luam metabolic pov tseg, co toxins, thiab electrolyte imbalances raug tshem tawm.
Colonal Dialysis
Colonal dialysis yuav tsum tau txhaj cov dej lim rau hauv txoj hnyuv rau kev ntxuav thiab tshem tawm cov co toxins, ua kom qhov chaw sib cuag ntawm lub plab hnyuv thiab tshuaj. Cov tshuaj tshwj xeeb yog tom qab ntawd txhaj tshuaj, tso cai rau nws kom nqus tau ntau yam co toxins los ntawm lub plab mucosa thiab tshem tawm sai. Thaum kawg, kev npaj tshuaj suav tshuaj tshwj xeeb yog infused thiab khaws cia, qhov twg cov kab mob colonic absorbs cov khoom xyaw nquag, muab cov txiaj ntsig kho rau lub raum thiab txo cov co toxins xws li creatinine, urea nitrogen, thiab uric acid.
