I-Central venous catheter (CVCs)kanye nama-catheter aphakathi nendawo afakwe nge-peripheral (I-PICCs) zingamathuluzi abalulekile emithini yesimanje, asetshenziselwa ukuletha imithi, imisoco, nezinye izinto ezibalulekile ngqo egazini. I-Shanghai Teamstand Corporation, umphakeli ochwepheshe kanye nomkhiqizi weimishini yezokwelapha, inikeza zombili izinhlobo zama-catheter. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-catheter kungasiza ochwepheshe bezokunakekelwa kwempilo ukuthi bakhethe idivayisi elungele iziguli zabo.
Iyini i-CVC?
A I-Central Venous Catheter(i-CVC), eyaziwa nangokuthi umugqa omaphakathi, iyishubhu elide, elincanyana, eligobekayo elifakwe ngomthambo osentanyeni, esifubeni, noma okhalweni futhi liqhubekele emithanjeni emaphakathi eduze kwenhliziyo. Ama-CVC asetshenziselwa izinhloso ezahlukahlukene, kufaka phakathi:
- Ukuphatha imithi: Ikakhulukazi leyo ecasulayo emithanjeni ye-peripheral.
- Ukunikeza ukwelashwa kwe-intravenous (IV) yesikhathi eside: Okufana ne-chemotherapy, i-antibiotic therapy, kanye nokudla okuphelele komzali (TPN).
- Ukuqapha ingcindezi ye-venous emaphakathi: Ezigulini ezigula kakhulu.
– Ukudweba igazi ukuze lihlolwe: Lapho kudingeka amasampula njalo.
CVCsingaba nama-lumens amaningi (iziteshi) ezivumela ukuphathwa kanyekanye kwemithi ehlukene. Ngokuvamile zenzelwe ukusetshenziswa kwesikhathi esifushane ukuya esimaphakathi, ngokuvamile kufika emavikini ambalwa, nakuba ezinye izinhlobo zingasetshenziswa isikhathi eside.
Yini i-PICC?
I-Peripherally Inserted Central Catheter (PICC) iwuhlobo lwe-catheter emaphakathi efakwa ngomthambo ojikelezayo, ngokuvamile engxenyeni engenhla, futhi iqhubeke kuze kube yilapho ichopho lifinyelela umthambo omkhulu eduze kwenhliziyo. Ama-PICC asetshenziselwa izinjongo ezifanayo nama-CVC, okuhlanganisa:
- Ukufinyelela kwe-IV yesikhathi eside: Imvamisa ezigulini ezidinga ukwelashwa okunwetshiwe okufana nokwelashwa ngamakhemikhali noma ukwelashwa kwemithi elwa namagciwane isikhathi eside.
- Ukunikeza imithi: Idinga ukulethwa endaweni eyodwa kodwa isikhathi eside.
- Ukudweba igazi: Ukunciphisa isidingo sezinti yenaliti eziphindaphindiwe.
Ama-PICC ngokuvamile asetshenziswa isikhathi eside kunama-CVC, ngokuvamile ukusuka emavikini ambalwa ukuya ezinyangeni. Awahlaseli kancane kunama-CVC njengoba isayithi lawo lokufaka lisemthanjeni oseduze kune-central.
Umehluko Obalulekile Phakathi kwe-CVC ne-PICC
1. Isayithi Lokufaka:
- I-CVC: Ifakwe emthanjeni ophakathi nendawo, ngokuvamile entanyeni, esifubeni, noma enqenqemeni.
– I-PICC: Ifakwe emthanjeni osemngceleni osengalweni.
2. Inqubo Yokufaka:
- I-CVC: Ivamise ukufakwa endaweni yesibhedlela, ngokuvamile ngaphansi kwe-fluoroscopy noma isiqondiso se-ultrasound. Ivamise ukudinga izimo eziyinyumba kakhudlwana futhi iyinkimbinkimbi kakhulu.
– I-PICC: Ingafakwa eduze kombhede noma endaweni yesiguli esingalalisiwe, ngokuvamile ngaphansi kokuqondiswa kwe-ultrasound, okwenza inqubo ingabi yinkimbinkimbi futhi ihlasele.
3. Isikhathi Sokusetshenziswa:
- I-CVC: Ngokuvamile ihloselwe ukusetshenziswa okufushane kuya kwesikhathi esimaphakathi (kufika emavikini ambalwa).
- I-PICC: Ilungele ukusetshenziswa isikhathi eside (amasonto kuya ezinyangeni).
4. Izinkinga:
- I-CVC: Ingozi ephezulu yezinkinga ezifana nokutheleleka, i-pneumothorax, ne-thrombosis ngenxa yendawo emaphakathi ye-catheter.
- I-PICC: Ingozi ephansi yezinye izinkinga kodwa isaphethe izingozi ezifana ne-thrombosis, ukutheleleka, nokuvala i-catheter.
5. Induduzo Yesiguli Nokuhamba:
- I-CVC: Ingakhululeka kancane ezigulini ngenxa yendawo yokufaka kanye namandla okuvinjelwa kokunyakaza.
- I-PICC: Ngokujwayelekile inethezekile futhi ivumela ukuhamba okukhulu kweziguli.
Isiphetho
Womabili ama-CVC nama-PICC amathuluzi ezokwelapha abalulekile ahlinzekwa yi-Shanghai Teamstand Corporation, ngalinye linikeza izidingo ezithile ngokusekelwe esimweni sesiguli kanye nezidingo zokwelashwa. Ama-CVC ngokuvamile akhethelwa ukwelashwa nokuqapha okujulile kwesikhashana, kuyilapho ama-PICC ethandwa ukwelashwa kwesikhathi eside nokunethezeka kwesiguli. Ukuqonda lo mehluko kubalulekile ukuze abahlinzeki bezokunakekelwa kwempilo benze izinqumo ezinolwazi futhi banikeze ukunakekelwa okungcono kakhulu kweziguli zabo.
