Amadivayisi ezokwelaphazidlala indima ebalulekile emkhakheni wezokunakekelwa kwempilo ngokusiza ekuhlinzeni nasekuphatheni okuhlukahlukene. Phakathi kwamadivayisi amaningi ezokwelapha,izinaliti ze-fistula ezitholakala emithanjeni yegazibathole ukunakwa kabanzi ngenxa yendima yabo ebalulekile ku-i-hemodialysisOsayizi bezinaliti ze-AV fistula njenge-15G, 16G kanye ne-17G bathandwa kakhulu kulesi simo. Kulesi sihloko, sizohlola osayizi abahlukene kanye nezici zezinaliti ze-AV fistula kanye nokubaluleka kwazo emkhakheni wezokwelapha.
Izinaliti ze-AV Fistula zenzelwe ukudala i-arteriovenous fistula, ezibalulekile ezigulini ezihlinzwa nge-hemodialysis. Lezi zinaliti zisebenza njengemigudu phakathi kwegazi nomshini wokuhlanza igazi, zisusa ngempumelelo imfucuza kanye noketshezi oluningi emzimbeni. Enye yezinto ezibalulekile okufanele uzicabangele lapho ukhetha i-Inaliti ye-AV fistulausayizi ofanele ukuqinisekisa ukusebenza kahle kanye nenduduzo yesiguli.
Osayizi bezinaliti ze-AV fistula ezisetshenziswa kakhulu yi-15G, 16G, kanye ne-17G. U-“G” ubhekisela ku-gauge, okubonisa ububanzi benaliti. Izinombolo ze-gauge eziphansi zihambisana nosayizi bezinaliti ezinkulu. Isibonelo,Inaliti ye-AV Fistula 15Ginobubanzi obukhulu uma kuqhathaniswa nezinketho ze-16G kanye ne-17G. Ukukhetha usayizi wenalithi kuncike ezintweni eziningana, okuhlanganisa usayizi wemithambo yesiguli, ukulula kokufakwa, kanye nokugeleza kwegazi okudingekayo ukuze kuhlanjululwe kahle igazi.
Inaliti ye-AV fistula engu-15G inobubanzi obukhulu futhi ivame ukusetshenziswa ezigulini ezinemithambo emikhulu. Lobu bukhulu buvumela amazinga aphezulu okugeleza kwegazi ngesikhathi sokuhlanza igazi, okuvumela ukususwa kwemfucuza okuphumelelayo kanye nokwandisa ukusebenza kahle kokuhlinzwa. Kodwa-ke, ukufaka izinaliti ezinkulu kungaba nzima kakhulu futhi kungabangela ukungakhululeki kwezinye iziguli.
Kubantu abanemithambo ebuthakathaka kakhulu, izinaliti ze-AV fistula ezingu-16G kanye no-17G zivame ukusetshenziswa. Lezi zilini ezincane ezinobubanzi kulula ukuzifaka, okudala umuzwa omncane wokungena ezigulini. Nakuba ukugeleza kwegazi kungase kube phansi kancane uma kuqhathaniswa nenaliti engu-15G, kusanele ekuhlanzeni igazi okusebenzayo ezimweni eziningi.
Ngaphezu kosayizi,izinaliti ze-fistula ezitholakala emithanjeni yegazizinezakhiwo eziningana ezithuthukisa ukusebenza kwazo. Isici esibalulekile yi-bevel yenaliti, ebhekisela encazelweni egobile. I-engeli kanye nokubukhali kwe-bevel kudlala indima ebalulekile ekufakweni kalula nasekunciphiseni ukulimala kwezicubu zesiguli. Izinaliti ezine-bevels eziklanywe ngokucophelela zithuthukisa ulwazi oluphelele kochwepheshe bezempilo kanye neziguli.
Ngaphezu kwalokho, izinaliti ze-AV fistula zivame ukuqukatha izindlela zokuphepha zokuvimbela ukulimala kwenaliti ngengozi nokukhuthaza ukulawulwa kokutheleleka. Lezi zici zokuphepha zifaka phakathi izindlela ezihoxiswayo noma zokuvikela ezimboza inalithi ngemva kokusetshenziswa, ngaleyo ndlela kunciphisa ingozi yezingozi ezihlobene nenalithi.
Esinye isici esibalulekile okufanele sicatshangelwe yikhwalithi yezinto zenaliti. Izinaliti ze-AV fistula zivame ukwenziwa ngensimbi engagqwali noma ezinye izinto ezihambisana ne-biochemical zezinga lezokwelapha. Ukukhethwa kwezinto kuqinisekisa ukuqina kwenaliti nokuhambisana nomzimba wesiguli, kunciphisa ukusabela okubi okungenzeka.
Ngamafuphi, inaliti ye-AV fistula iyithuluzi elibalulekile lezokwelapha elisetshenziswa ngesikhathi se-hemodialysis. Ukukhetha usayizi ofanele, njengenaliti ye-AV fistula engu-15G, 16G, noma i-17G, kuncike ezicini nasezidingweni zesiguli ngasinye. Inaliti ye-15G ivumela ukugeleza kwegazi okuphezulu, kuyilapho izinaliti ze-16G kanye ne-17G zifaneleka kangcono iziguli ezinemithambo ebuthakathaka. Kungakhathaliseki usayizi, lezi zinaliti zifaka izici ezifana nemiklamo egobile kanye nezindlela zokuphepha zokuthuthukisa ukusebenza kwazo nokuqinisekisa ukuphepha kwesiguli. Ikhwalithi yezinto zenaliti nayo ibalulekile ekuhlinzekeni ngamadivayisi ezokwelapha athembekile nahambisanayo. Njengoba ubuchwepheshe bezinaliti ze-AV fistula buqhubeka nokuthuthuka, ochwepheshe bezempilo banganikeza ukunakekelwa okungcono futhi bathuthukise ulwazi oluphelele lweziguli ezihlinzwa nge-hemodialysis.
