Imishini yezokwelaphadlala indima ebalulekile emkhakheni wezokunakekelwa kwempilo ngokusiza ekuhlinzeni nasekulapheni okuhlukahlukene.Phakathi kwemishini eminingi yezokwelapha,izinaliti ze-arteriovenous fistulabathole ukunakwa okusabalele ngenxa yeqhaza labo elibalulekile kuhemodialysis.Osayizi bezinaliti ze-AV fistula njenge-15G, 16G ne-17G baziwa kakhulu kulesi simo.Kulesi sihloko, sizohlola amasayizi ahlukene nezici zezinaliti ze-AV fistula kanye nokubaluleka kwazo emkhakheni wezokwelapha.
Izinaliti ze-AV Fistula zenzelwe ukudala i-arteriovenous fistula, ebaluleke kakhulu ezigulini ezihlolwa nge-hemodialysis.Lezi zinaliti zisebenza njengemigudu phakathi kwegazi nomshini wokucofa amanzi, zikhipha ukungcola kanye noketshezi oluningi emzimbeni.Enye yezinto ezibalulekile okufanele uzicabangele lapho ukhetha i-anAV inaliti ye-fistulausayizi ofanele wokuqinisekisa ukusebenza kahle nokunethezeka kwesiguli.
Osayizi bezinaliti ze-AV fistula ezisetshenziswa kakhulu yi-15G, 16G, kanye ne-17G.U-“G” ubhekisela kugeji, okubonisa ububanzi benaliti.Izinombolo zegeji ephansi zihambisana nosayizi bezinaliti ezinkulu.Ngokwesibonelo, iI-AV Fistula Needle 15Ginobubanzi obukhulu uma kuqhathaniswa nezinketho ze-16G ne-17G.Ukukhetha ubukhulu benaliti kuncike ezicini eziningana, okuhlanganisa ubukhulu bemithambo yesiguli, ukushutheka kalula, nokugeleza kwegazi okudingekayo ukuze kusetshenziswe i-dialysis ephumelelayo.
I-AV fistula inaliti engu-15G inobubanzi obukhulu futhi ivame ukusetshenziswa ezigulini ezinemithambo ewugqinsi.Lo sayizi uvumela amazinga aphezulu okugeleza kwegazi ngesikhathi se-dialysis, okuvumela ukukhishwa kwemfucuza okuphumelelayo nokwandisa ukusebenza kahle kokuhlinzwa.Nokho, ukufaka izinaliti ezinkulu kungaba inselele futhi kungase kubangele ukungakhululeki kwezinye iziguli.
Kubantu abanemithambo entekenteke kakhulu, izinaliti ze-AV fistula 16G ne-17G zivame ukusetshenziswa.Lezi zinaliti ezinobubanzi obuncane kulula ukuzifaka, okudala umuzwa ongemuhle ezigulini.Nakuba ukugeleza kwegazi kungase kube ngaphansi kancane uma kuqhathaniswa nenaliti engu-15G, kusanele ukudayela okusebenzayo ezimweni eziningi.
Ngaphezu kosayizi,izinaliti ze-arteriovenous fistulazinezici eziningana ezithuthukisa ukusebenza kwazo.Isici esiyinhloko i-bevel yenaliti, ebhekisela kuphuzu eline-angle.I-engeli nokucija kwe-bevel kudlala indima ebalulekile ekufakeni kalula nasekunciphiseni ukuhlukumezeka kwezicubu zesiguli.Izinaliti ezinama-bevel aklanywe ngokucophelela zithuthukisa ulwazi oluphelele lochwepheshe bezempilo neziguli.
Ukwengeza, izinaliti ze-AV fistula zivame ukuqukatha izindlela zokuphepha zokuvimbela ukulimala kwenaliti ngengozi futhi zikhuthaze ukulawula ukutheleleka.Lezi zici zokuphepha zihlanganisa izindlela ezihlehliswayo noma ezivikelayo ezivala inaliti ngemva kokusetshenziswa, ngaleyo ndlela kuncishiswe ubungozi bezingozi ezihlobene nezinaliti.
Esinye isici esibalulekile okufanele sicatshangelwe yikhwalithi yezinto zenaliti.Izinaliti ze-AV fistula ngokuvamile zenziwe ngensimbi engagqwali noma ezinye izinto ezihambisana ne-biocompatible zebanga lezokwelapha.Ukukhethwa kwezinto kuqinisekisa ukuqina kwenaliti nokuhambisana nomzimba wesiguli, kunciphisa ukusabela okubi okungaba khona.
Kafushane, inaliti ye-AV fistula iyithuluzi lezokwelapha elibalulekile elisetshenziswa ngesikhathi sokuhlaziywa kwe-hemodialysis.Ukukhetha usayizi ofanelekile, njengenaliti ye-AV fistula 15G, 16G, noma i-17G, kuncike kuzici nezidingo zesiguli ngasinye.Inalithi ye-15G ivumela ukugeleza kwegazi okuphezulu, kuyilapho izinaliti ze-16G ne-17G zifaneleka kangcono ezigulini ezinemithambo ebuthakathaka.Kungakhathaliseki ukuthi zingakanani, lezi zinaliti zihlanganisa izici ezifana nemiklamo e-beveled nezindlela zokuphepha ukuze kuthuthukiswe ukusebenza kwazo nokuqinisekisa ukuphepha kwesiguli.Izinga lezinto zenaliti libalulekile futhi ekuhlinzekeni ngamadivaysi ezokwelapha athembekile futhi ahambisanayo.Njengoba ubuchwepheshe benaliti ye-AV fistula buqhubeka nokuthuthuka futhi buthuthuka, ochwepheshe bezokunakekelwa kwempilo banganikeza ukunakekelwa okungcono futhi bathuthukise ulwazi oluphelele lweziguli ezihlolwa nge-hemodialysis.
