Izixhobo zonyangodlala indima ebalulekileyo kwicandelo lokhathalelo lwempilo ngokuncedisa kuqhaqho olwahlukeneyo kunye nonyango. Phakathi kwezixhobo ezininzi zonyango,iinaliti ze-arteriovenous fistulabaye bafumana uqwalaselo olubanzi ngenxa yendima yabo ebalulekileyo kwihemodialysis. Iisayizi zenaliti ze-AV ze-fistula ezifana ne-15G, i-16G kunye ne-17G zithandwa kakhulu kule meko. Kule nqaku, siza kuhlolisisa ubukhulu obuhlukeneyo kunye neempawu zeenaliti ze-AV ze-fistula kunye nokubaluleka kwazo kwinkalo yonyango.
Iinaliti ze-AV Fistula zenzelwe ukudala i-arteriovenous fistulas, ebaluleke kakhulu kwizigulane ezihamba nge-hemodialysis. Ezi naliti zisebenza njengemibhobho phakathi kwegazi kunye nomatshini we-dialysis, ngokufanelekileyo ukususa iimveliso zenkunkuma kunye nolwelo olugqithisileyo emzimbeni. Enye yeengqwalasela eziphambili xa ukhetha iinaliti ye-AV ye-fistulaubungakanani obufanelekileyo bokuqinisekisa ukusebenza kakuhle kunye nokuthuthuzelwa kwesigulane.
Ezona zisetyenziswa ngokuqhelekileyo iisayizi zenaliti ze-AV fistula yi-15G, 16G, kunye ne-17G. "G" ibhekisa kwigeyiji, ebonisa ububanzi benaliti. Amanani egeyiji esezantsi ahambelana nobungakanani benaliti ezinkulu. Umzekelo, iInaliti ye-AV Fistula 15Ginobubanzi obukhulu xa kuthelekiswa ne-16G kunye ne-17G iinketho. Ukukhethwa kobungakanani benaliti kuxhomekeke kwizinto eziliqela, kuquka ubungakanani bemithambo yesigulana, ukuyifaka lula, kunye nokuhamba kwegazi okufunekayo ukuze kwenziwe uhlaziyo olusebenzayo.
Inaliti ye-AV fistula 15G inobukhulu obukhulu kwaye isoloko isetyenziswa kwizigulana ezinemithambo engqingqwa. Lo bungakanani buvumela amazinga aphezulu okuhamba kwegazi ngexesha le-dialysis, ukuvumela ukususwa kwenkunkuma ngokufanelekileyo kunye nokwandisa ukusebenza kakuhle kotyando. Nangona kunjalo, ukufaka iinaliti ezinkulu kunokuba ngumceli mngeni kwaye kunokubangela ukungakhululeki kwezinye izigulana.
Kubantu abanemithambo eethe-ethe ngakumbi, iinaliti ze-AV fistula 16G kunye ne-17G ziqhele ukusetyenziswa. Ezi naliti ezincinci ze-diameter zilula ukuzifaka, ukudala amava angaphantsi kwezigulane. Nangona ukuhamba kwegazi kunokuba ngaphantsi kancinci xa kuthelekiswa nenaliti ye-15G, isanele kwi-dialysis esebenzayo kwiimeko ezininzi.
Ukongeza kubukhulu,iinaliti ze-arteriovenous fistulazineempawu ezininzi eziphucula ukusebenza kwazo. Uphawu oluphambili yi-bevel yenaliti, ebhekisela kwincam ye-angled. I-angle kunye nobukhali be-bevel badlala indima ebalulekileyo ekufakeni lula kunye nokunciphisa ukuxhatshazwa kwizicubu zesigulane. Iinaliti ezinee-bevels eziyilwe ngononophelo ziphucula amava ewonke kubasebenzi bezempilo kunye nezigulana.
Ukongeza, iinaliti ze-AV fistula zihlala ziqulethe iindlela zokhuseleko zokuthintela ukwenzakala kwinaliti ngengozi kunye nokukhuthaza ulawulo losulelo. Ezi mpawu zokhuseleko ziquka izixhobo ezirhoxiswayo okanye ezikhuselayo ezivala inaliti emva kokusetyenziswa, ngaloo ndlela zinciphisa umngcipheko weengozi ezinxulumene nenaliti.
Enye into ebalulekileyo ekufuneka iqwalaselwe ngumgangatho wezinto yenaliti. Iinaliti ze-AV ze-fistula zenziwe ngentsimbi engenasici okanye ezinye izinto ezihambelana ne-biocompatible zonyango. Ukukhethwa kwezinto eziphathekayo kuqinisekisa ukuqina kweenaliti kunye nokuhambelana nomzimba wesigulane, ukunciphisa ukusabela okubi okunokwenzeka.
Isishwankathelo, inaliti ye-AV fistula sisixhobo esibalulekileyo sonyango esisetyenziswe ngexesha le-hemodialysis. Ukukhetha ubungakanani obufanelekileyo, njenge-AV fistula inaliti 15G, 16G, okanye i-17G, kuxhomekeke kwiimpawu zesigulane kunye neemfuno. Inaliti ye-15G ivumela ukuhamba kwegazi okuphezulu, ngelixa iinaliti ze-16G kunye ne-17G zilungele kangcono izigulane ezineemitha ezibuthathaka. Kungakhathaliseki ubungakanani, ezi naliti zibandakanya iimpawu ezifana noyilo lwe-beveled kunye neendlela zokhuseleko zokuphucula ukusebenza kwazo kunye nokuqinisekisa ukhuseleko lwesigulane. Umgangatho wezinto zenaliti nazo zibalulekile ekuboneleleni ngezixhobo zonyango ezithembekileyo nezihambelanayo. Njengoko iteknoloji yenaliti ye-AV ye-fistula iqhubeka nokuqhubela phambili kunye nokuphucula, abaqeqeshi bezempilo banokubonelela ngononophelo olungcono kunye nokuphucula amava apheleleyo kwizigulane ezihamba nge-hemodialysis.
