Kana zvasvika kune dialysis, kusarudza yakakodzeraAV fistula tsonoinokosha. Izvi zvinoita sezvidikimudziyo wekurapainoita basa rakakosha mukuona kuchengetedzwa kwemurwere, kunyaradzwa, uye kurapa kwakanaka. Ungave uri murapi, mutarisiri wehutano, kana maneja wezvekurapa, unonzwisisa nzira yekusarudza kwayofistula tsono ye dialysiskwakakosha.
Muchikamu chino, tichaongorora kuti AV fistula tsono chii, nei ichikosha, uye 9 zvinhu zvikuru zvekufunga nezvazvo pakusarudza imwe. Tichabatawo masaizi akajairwa seAV fistula tsono 15G, 16G, uye 17G kubatsira kutungamira sarudzo yako.
Chii chinonzi anAV Fistula Tsono?
An arteriovenous (AV) fistula tsono inyanzvi ye dialysis inoshandiswa kuwana ropa remurwere kuburikidza ne arteriovenous fistula panguva.hemodialysis. Iyo AV fistula inobatanidza nekuvhiya pakati petsinga netsinga, kazhinji iri muruoko, iyo inobvumira kubuda kweropa kwakakwira kunodiwa kuitira dialysis inoshanda.
Iyo AV fistula tsono inopinzwa mufistula kuti ibudise ropa kuti icheneswe yozoidzosera kumuviri. Idzi tsono dzakakoshazvekurapamunzvimbo dze dialysis uye muzvipatara, uye kusarudza iyo chaiyo haisi yekungoenderana nemidziyo - ndeye kugadzirisa mhedzisiro yemurwere.

9 Zvinhu Zvikuru Pakusarudza KodzeroAV Fistula Tsono
1. Needle Gauge
Iyo tsono gauge inosarudza dhayamita yetsono uye inokanganisa zvakananga kuyerera kweropa. Saizi dzakajairika dzinosanganisira:
AV fistula tsono 15G: Inopa dhayamita yakakura, inobvumira kukwira kweropa kuyerera. Inonyanya kushandiswa kuvarwere vakuru vane fistula yakakura.
AV fistula tsono 16G: Saizi yakasiyana-siyana kuyera kuyerera mwero uye kunyaradza kwemurwere.
AV fistula tsono 17G: Diki dhayamita, yakakodzera varwere vevana kana avo vane tsinga dzisina kusimba.
Kusarudza geji chaiyo kunosanganisira kutarisa mamiriro etsinga yemurwere, kuyerera kweropa, uye chirongwa chekurapa.
Tafura 1. Kufananidza geji uye kuyerera kweropa
| Kuyerera kweropa (BFR) | Inokurudzirwa tsono geji |
| <300 ml/min | 17 gauge |
| 300-350 ml / min | 16 geji |
| > 350-450 ml/min | 15 geji |
| >450 ml/min | 14 geji |
2. Kureba kwetsono
Urefu ndechimwe chinhu chinokosha. Tsono dzinowanzo kuwanikwa mukureba kubva pa25mm kusvika 38mm. Kureba kwetsono kunofanira kukwana kusvika kumadziro efistula pasina kureba, izvo zvinogona kukonzera kukanganisa. Kureba kwetsono kwakakodzera kunonatsiridza kupinza kwechokwadi uye kunoderedza kusagadzikana.
Tafura 2. Kufananidza urefu hwetsono maererano nekure kune ganda
| Kureba kweganda | Inokurudzirwa urefu hwetsono |
| <0.4 masendimita pazasi peganda | 3/4" uye 3/5" ye fistulas |
| 0.4-1 cm kubva paganda | 1″ kune fistulas |
| ≥1 cm kubva pamusoro peganda | 1 1/4" ye fistulas |
3. Bevel Dhizaini
The bevel ndiyo inorereka mupendero wetsono. Iyo bevel dhizaini yakanyanya kupinza inogona kukonzera kukuvadzwa kumadziro efistula, nepo bevel rakanyanya kusimba rinogona kukonzera kunetsa kubaya ganda. Iyo yakanaka bevel dhizaini ichasiyana kune mumwe nemumwe zvichienderana nehukuru uye mamiriro efistula yavo. Mhando dzakajairika dzinosanganisira:
Short bevel: Zviri nyore kudzora, zvishoma zvishoma kubvarura tishu
Yakareba bevel: Yakapinza uye inobvumira kupinda kwakapfava, asi ingangoda humwe hunyanzvi
Kusarudza bevel rakakodzera kunogona kuderedza zvakanyanya kurwadziwa kwemurwere uye matambudziko panguva ye cannulation.
4. Nyaya Yetsono
Tsono zvinhu zvinokanganisa zvese kushanda uye kuchengetedzwa kwemurwere. Tsono dzesimbi dzepamusoro-soro dzinonyanya kuwanda nekuda kwesimba radzo, kupinza, uye biocompatibility. Aseptic Fistula tsono dzinofanirwa kugadzirwa zvemhando yepamusoro, zvekurapa-giredhi zvinhu kuderedza njodzi yekutapukirwa. Izvo zvakakosha kuti usarudze tsono kubva kune ane mukurumbira av fistula tsono anogadzira kuti ave nechokwadi chekuchengetedza uye kusimba.
5. Kutenderera Hub Tsono
Inotenderera hub tsono inobvumira 360-degree kutenderera pasina kubvisa tsono kubva panzvimbo yayo. Iyi ficha inonyanya kubatsira mukudzikisa tubing kinks uye kuchinjika kune murwere kufamba panguva yedialysis zvikamu. Inovandudzawo nyaradzo uye inorerutsa kugadzirisa panguva yekurapa.
6. Mapapiro eKubata Kwakachengeteka
WingedAV fistula tsonokupa kuwedzera kugadzikana uye kubata. Aya mapapiro e butterfly anoshanduka anobvumira vanochengeta kuchengetedza tsono zviri nyore uye kupa kubata zviri nani panguva yekuisa. Mapapiro anonyanya kubatsira kune vanozvirova-cannulata uye anobatsira kuderedza kuburitswa netsaona panguva yedialysis.
7. Nzira dzekudzivirira Ropa Kudzokera shure
Kudzivirira kubuda kweropa kwakakosha kune kuchengetedzwa kwemurwere. Dzimwe AV fistula tsono dzakagadzirwa nemavharuvhu enzira imwe kana nzira dzemukati dzinoderedza njodzi yekudzokera shure, zvichibatsira ku:
Dzivirira kuvhara muchubhu
Chengetedza kusabereka
Kuvandudza dialysis kushanda zvakanaka
Ichi chimiro chinova chakanyanya kukosha mumasesheni akareba edialysis kana nevarwere vane dambudziko rekugwamba.
8. Needle Retraction Mechanism
Nzira dzemazuva ano dzekudzosa tsono dzakagadzirirwa kusimbisa kuchengetedzwa nekudzikisa njodzi yekukuvara kwetsono mushure mekushandisa. Matanho aya anongodzoreredza tsono mune inodzivirira casing post-cannulation, ichiva nechokwadi chekuchengetedza murwere uye muchengeti.
Tsono dzinodzokororwa dziri kuwedzera kuve dzakajairwa muzvirongwa zvekiriniki nekuda kwekuteerera kwavo neanopinza mitemo yekuchengetedza.
9. Rongedza Kunyaradza Murwere
Pakupedzisira, yakanakisa AV fistula tsono ndiyo inowedzera kunyaradza kwemurwere. Kupinza kwetsono, kupeta, kona yekuisa, uye kunyange kurongedza ergonomics zvese zvinopa kune chiitiko chese. Iyo yakatsetseka, isingarwadze dialysis sesheni inotungamira kune yakakwira kuteedzera kwemurwere uye nemhedzisiro iri nani nekufamba kwenguva.
Sei Iyo Yakarurama Fistula Needle Inokosha?
Kusarudza iyo fistula tsono chaiyo yedialysis haingori sarudzo yehunyanzvi-inobata zvakananga hutano hwemurwere uye nyaradzo. Heino chikonzero nei zvakakosha:
Inovandudza dialysis kushanda zvakanaka:Saizi chaiyo yetsono uye dhizaini inosimudzira yakakwana yekuyerera kweropa.
Zvinoderedza matambudziko:Tsono dzakanyatsosarudzwa dzinoderedza kushungurudzika, kupinza, uye kugwamba.
Kunowedzera kuchengeteka:Zvimiro senge nzira dzekudzosera uye anti-backflow dhizaini inodzivirira varwere nevashandi.
Inowedzera kunyaradza:Tsono iri nyore kuisa uye inokonzeresa kusagadzikana kudiki inowedzera kuvimba nemurwere uye kuda kugara uchirapwa.
Nehemodialysis kuve kurapwa kwenguva refu, kutsigira hupenyu, zvese zvine basa. Ndosaka makiriniki nevashandi vehutano vachifanira kuisa nguva mukusarudza iyo dialysis tsono yenyaya yega yega.
Mhedziso
Muchidimbu, theAV fistula tsonochinopfuura chishandiso chete-chinhu chakakosha mukuunza kuchengetedza uye kunoshanda kwekuchengetedza dialysis. Kubva pakukura kwegeji uye zvinhu kusvika kumaitiro ekudzoreredza uye kunyaradza kwemurwere, ese maficha anoita basa.
Ungave uri kusarudza pakati peAV fistula tsono 15G, 16G, kana 17G, funga zvinhu zvipfumbamwe zvakurukurwa pamusoro apa kuti uite sarudzo ine ruzivo. Nekuita izvi, haungonatsiri mhedzisiro yekiriniki chete asi zvakare unovandudza zvakanyanya ruzivo rwemurwere dialysis.
