Igazi elilahlwayo elingenamagciwanei-catheter ye-hemodialysiskanye nezesekeli Ezilahlwayo ezihlanzekilei-catheter ye-hemodialysisisakhiwo nokusebenza komkhiqizo kanye nokwakheka kwawo lo mkhiqizo wakhiwe ngesihloko esithambile, isihlalo esixhumanisayo, ishubhu yokwelula kanye nesokhethi yekhoni; I-catheter yenziwe nge-polyurethane yezokwelapha kanye ne-polycarbonate. Iyi-cavity eyodwa, i-cavity ephindwe kabili kanye ne-catheter ephindwe kathathu. Lo mkhiqizo usetshenziselwa ngokwezokwelapha i-hemodialysis kanye ne-infusion. Imininingwane imodeli i-cavity ephindwe kabili, i-cavity emithathu
Umhubhe womhubhe onejakethi ye-dacron

Njengoba umphakathi usugugile, umfutho wegazi ophakeme, isifo sikashukela, isifo senhliziyo (CHD) kanye neziguli ezihluleka ukwehluleka kwezinso zikhula, isimo semithambo yegazi sibi, i-autogenous arteriovenous internal fistula ikhuphuka kakhulu izehlakalo zezinkinga, zithinta kakhulu umphumela wokwelashwa kwe-dialysis wesiguli kanye nekhwalithi yokuphila, ngakho-ke thatha i-catheter noma i-catheter yebhande le-polyester isikhathi eside, ibilokhu isetshenziswa kabanzi emhlabeni, inzuzo yayo iwukuthi: I-catheter ihambisana kahle ne-biocompatibility, futhi i-catheter ingalungiswa ngokuqinile nesikhumba. Isikhwama sayo se-polyester singakha isithiyo esivaliwe samagciwane emhubheni ongaphansi komhlaba, sinciphise ukwenzeka kokutheleleka futhi sandise kakhulu isikhathi sokusetshenziswa.
Ukusetshenziswa nokugcinwa kwama-catheter e-hemodialysis

1. Ukunakekelwa nokuhlolwa kwama-catheter

1. Indawo yokukhipha isikhumba se-catheter

Ngaphambi nangemva kokusetshenziswa ngakunye, ukubonakala komthombo wesikhumba endaweni yokufaka ipayipi kufanele kuhlolwe ukuthi ubomvu, ukukhishwa, ubuthakathaka, ukopha kanye nokukhishwa kwe-exudation, njll. Uma kuyi-catheter yesikhashana, hlola ukuqina kwenaliti yokuthungwa. Uma kuyi-catheter yesikhathi eside, bheka ukuthi i-CAFF idonsiwe noma iphumile yini.

2. Ilunga langaphandle le-catheter

Kungakhathaliseki ukuthi kukhona ukuqhekeka noma ukuqhekeka, izinga lokuqina kwe-lumen, uma kutholakala ukugeleza kwegazi okwanele, kufanele kubikwe kudokotela ngesikhathi, futhi ukwakheka kwe-thrombus kanye ne-fibrin sheath ku-catheter kufanele kunqunywe nge-ultrasound, i-imaging kanye nezinye izindlela.

3. Izimpawu zesiguli

Kungakhathaliseki ukuthi izimpawu kanye nezinga lomkhuhlane, amakhaza, ubuhlungu kanye nezinye izikhalazo zokungakhululeki.

2. Inqubo yokusebenza koxhumano

1. Ukulungiselela

(1) Umshini wokuhlanza udlulile ekuzihloleni, ipayipi lokuhlanza uhlanziwe futhi lisesimweni sokulinda.

(2) Ukulungiselela: inqola yokwelapha noma ithileyi yokwelapha, izinto zokubulala amagciwane (iodophor noma i-chlorhexidine), izinto ezingenamagciwane (ithawula lokwelapha, i-gauze, isirinji, amagilavu okuhlanza, njll.).

(3) Isiguli kufanele sibekwe endaweni ekhululekile yokulala phansi, kanti isiguli esine-intubation entanyeni kufanele sigqoke imaski ukuze siveze indawo ye-intubation.

2. Inqubo

(1) Vula i-dressing yangaphandle ye-catheter ephakathi kwemithambo yegazi.

(2) Gqoka amagilavu.

(3) Vula ingxenye eyodwa kwezine yethawula lokwelapha elihlanzekile bese ulibeka ngaphansi kwe-catheter ene-lumen ephindwe kabili yomthambo ophakathi.

(4) Ukuhlanza ngesikulufo isivalo sokuvikela i-catheter, umlomo we-catheter kanye ne-catheter clamp izikhathi ezimbili ngokulandelana.

(5) Hlola ukuthi i-catheter clamp iboshiwe, susa i-nut, bese uyilahla. Beka i-catheter ehlanziwe ngamagciwane ohlangothini oluyi-1/2 lwethawula lokwelapha.

(6) Hlanza umlomo futhi ngaphambi kokusebenza.

(7) Isixazululo se-heparin esivala i-intracatheter esingu-2mL sipompelwe emuva ngesirinji esingu-2-5ml sabe sesicindezelwa ku-gauze.

(8) Hlola ukuthi kukhona yini amahlule ku-gauze. Uma kukhona amahlule, khipha u-1ml futhi bese ucindezela umjovo. Ibanga phakathi komjovo ne-gauze likhulu kune-10cm.

(9) Ngemva kokwahlulela ukuthi i-catheter ayithintekile, xhuma imithambo yegazi kanye nemibhobho yemithambo yegazi yokujikeleza kwegazi ngaphandle komzimba ukuze usungule ukujikeleza kwegazi ngaphandle komzimba.

3. Qeda umsebenzi wokuvala ipayipi ngemva kokuhlanza igazi

(1) Ngemva kokwelashwa nokubuyiselwa kwegazi, cindezela i-catheter clamp, bulala amagciwane e-arteriovenous catheter joint, bese unqamula i-joint ngepayipi lokujikeleza kwegazi.

(2) Hlanza amagciwane endaweni yokungena kwemithambo yegazi kanye nomthambo we-catheter ngokulandelana, bese ucindezela usawoti ojwayelekile ongu-10ml ukuze ugeze i-catheter ngendlela yokushaya kwenhliziyo. Ngemva kokubuka ngamehlo angenalutho, bekungekho zinsalela zegazi engxenyeni eveziwe ye-catheter, cindezela uketshezi lokuvala i-anticoagulant nge-pellet njengoba kuyalelwe udokotela. (3) Sebenzisa isivalo se-heparin esingenamagciwane ukuvala ukuvulwa kwepayipi le-arteriovenous kanye nezendlalelo ezimbili ze-gauze engcolile ukuze uyisonge. Kulungisiwe.

3. Ukushintsha i-dressing ye-catheter yemithambo ephakathi

1. Hlola ukuthi i-dressing yomile, igazi namabala.

2. Gqoka amagilavu.

3. Vula ibhandeji bese uhlola ukuthi kukhona yini ukopha, ukuphuma kwegazi, ukubomvu nokuvuvukala, ukulimala kwesikhumba kanye nokuchitheka kwe-suture endaweni lapho kufakwa khona i-catheter yemithambo ephakathi.

4. Thatha i-iodophor cotton swab bese uyijikelezisa ngokwewashi ukuze ubulale amagciwane endaweni lapho ipayipi lifakwe khona. Ububanzi bokubulala amagciwane buyi-8-10cm.

5. Namathisela i-closure yesilonda esikhumbeni endaweni lapho ipayipi libekwe khona, bese ubonisa isikhathi sokushintsha i-closure. Ukusetshenziswa nokugcinwa kwama-catheter
