Arteriovenous (AV) fistula tsonokuita basa rakakosha muhemodialysis, mushonga unochengetedza upenyu kune varwere vane itsvo kusashanda zvakanaka. Idzi tsono dzinoshandiswa kuwana ropa remurwere kuburikidza neAV fistula, kubatanidza kwakagadzirwa nekuvhiyiwa pakati petsinga netsinga, zvichiita kuti ropa rifambe zvakanaka panguva yedialysis. Ichi chinyorwa chichaongorora mashandisirwo, zvakanakira, saizi, uye mhando dzeAV fistula tsono kuti ipe tarisiro yakazara yeiyi yakakosha mudziyo wekurapa.
Kushandiswa kweAV Fistula Needles muHemodialysis
Iyo tsono yeAV fistula yakagadzirirwa chaizvo varwere vari kuita hemodialysis. Iyo AV fistula, yakagadzirwa muruwoko rwemurwere, inoshanda senzvimbo yenguva refu yekuwana nzira yedialysis. Panguva yehemodialysis, tsono yeAV fistula inopinzwa mufistula, zvichiita kuti ropa riyerere richibuda mumuviri richipinda mumushini wedialysis, uko rinosefa rodzorerwa kumurwere.
Basa rekutanga retsono iyi nderekupa mukana uye wakavimbika wevascular mukana wekubvumira kuyerera kweropa kwakaringana, izvo zvakakosha kuti dialysis process ibvise muchetura uye mvura yakawandisa kubva muropa nemazvo. Kuiswa kweAV fistula tsono kunoda kunyatso uye kutarisirwa, sezvo kuiswa kusina kunaka kunogona kukonzera matambudziko, akadai sekupinda (apo tsono inopinda mumadziro emudziyo weropa), kubuda ropa, kana utachiona.
Zvakanakira zveAV Fistula Needles
AV fistula tsono dzinopa zvakati wandei zvakanakira mumamiriro ehemodialysis, kunyanya kana ichishandiswa neyakagadzirwa uye yakachengetedzwa fistulas. Zvimwe zvakakosha zvinobatsira zvinosanganisira:
1. Kuvimbika Kuwana Kuyerera Kweropa: AV fistula tsono dzakagadzirirwa kupa kugadzikana, kwenguva refu yevascular access. Iyo fistula inobvumira kukwira kweropa kuyerera, izvo zvakakosha pakuita dialysis inoshanda. Kushandisa tsono idzi kunopa mukana wakakodzera muropa uye kunobatsira kuchengetedza kunaka kwechikamu chedialysis.
2. Kuderedza Ngozi yeKutapukirwa: Kuenzaniswa nenechepakati venous catheters(CVCs) inoshandiswa padialysis, AV fistula tsono dzinoisa njodzi yakaderera yehutachiona. Sezvo AV fistula inogadzirwa kubva mutsinga dzeropa remurwere, njodzi yehutachiona senge bacteremia inoderera zvakanyanya.
3. Kuwedzera Kusimba: Iyo AV fistula pachayo inogara yakasimba uye inogara kwenguva refu yevascular access kupfuura dzimwe nzira, dzakadai semagadzirirwo emagetsi kana CVCs. Yakabatanidzwa neakanyatsogadzirwa AV fistula tsono, iyi nzira yekuwana inogona kushandiswa kwemakore, kuderedza kudiwa kwekudzokororwa kwekuvhiya.
4. Kuvandudzwa Kwekuyerera Kweropa: AV fistula tsono, yakasanganiswa nefistula ine utano, inobvumira kubuda kweropa zviri nani panguva yedialysis. Izvi zvinovandudza kushanda kweiyo dialysis process, zvichitungamira kucheneswa kwechepfu kubva muropa.
5. Yakaderedzwa Kuvhara Ngozi: Sezvo AV fistula inobatanidza zvisikwa pakati pe arteri uye mutsinga, ine ngozi yakaderera yekuvhara kana ichienzaniswa nedzimwe nzira dzekugadzira. AV fistula tsono inogona kushandiswa nguva dzose pasina matambudziko anowanzobatanidzwa nedzimwe nzira dzekuwana.
Tsono dzeAV fistula dzinouya muhukuru hwakasiyana, kazhinji hupimwa negeji, iyo inotara dhayamita yetsono. Saizi dzinonyanya kushandiswa muhemodialysis dzinosanganisira 14G, 15G, 16G uye 17G.
Nzira yekusarudza saizi dzetsono dzeAV Fistula Needle?
Yakakurudzirwa tsono geji | Kuyerera kweropa | Color |
17G | <300ml/min | Pink |
16G | 300-350ml / min | Girinhi |
15G | 350-450ml / min | Yero |

3/4" uye 3/5" | <0.4cm pazasi peganda |
1″ | 0.4-1cm kubva pamusoro peganda |
1 1/4" | > 1cm kubva pamusoro peganda |
Mhando dzeAV Fistula Needles
Mhando dzinoverengeka dzeAV fistula tsono dziripo, dzakagadzirirwa kusangana nezvinodiwa zvakasiyana zvevarwere vedialysis. Mhando dzinogona kusiyana mukugadzira uye maficha, kusanganisira nzira dzekuchengetedza uye nyore kuisa.
1. Kubva Pazvinhu
AVF tsono dzinowanzo gadzirwa kubva kuzvinhu zviviri zvikuru: simbi nepurasitiki.
a) Metal Needles: Metal AVF tsono ndiyo inonyanya kushandiswa muhemodialysis. Kune mhando mbiri dzesimbi tsono dzinobva pane cannulation tekinoroji:
Tsono Dzakapinza: Mupendero wakapinza, unoshandiswa mukugadzira tambo manera.
Blunt Needles: Edge yakatenderedza, inoshandiswa mubhatani gomba cannulation.
b) Tsono dzepurasitiki: Inoshandiswa kune yakadzika tsinga.
2. Kubva pane Safety Features
tsono dzeAVF dzakaiswawo muchikamu zvichienderana nekuvapo kwenzira dzekuchengetedza, dzakagadzirirwa kuchengetedza varwere nevashandi vehutano kubva mukukuvadzwa netsaona kana kusvibiswa. Kune marudzi maviri akakosha:
Disposable AVF Needles: Aya ndiwo akajairwa AVF tsono pasina mamwe maficha ekuchengetedza.
Chengetedzo AVF Tsono: Yakagadzirwa neakavakirwa-mukati ekuchengetedza masisitimu, chengetedzo AVF tsono dzakashongedzerwa kuti dzidzivirire kana kudzoreredza tsono mushure mekushandisa.
Mhedziso
AV fistula tsono chikamu chakakosha chehemodialysis process, ichipa yakavimbika vascular kuwana kune varwere vanoda kurapwa kwekutadza kweitsvo. Kushandiswa kwavo muhemodialysis kunogonesa kufamba kweropa, zvichiita kuti zvive nemigumisiro yakanaka yedialysis. Nehukuru hwakasiyana nemhando, kusanganisira kuchengetedza uye mabhatani sarudzo, tsono idzi dzinopa nyaradzo, kusimba, uye chengetedzo kune vese varwere nevarapi vehutano. Kusarudza saizi yetsono yakakodzera uye mhando zvichienderana nemamiriro emurwere kwakakosha kuve nechokwadi chekubudirira dialysis chiitiko.
