Ama-catheters asezingeni eliphakeme (CVCs)kanye nama-catheters afakwe emaphakathi (Ipikshanaamathuluzi abalulekile emithini yesimanje, esetshenziselwa ukuletha imithi, izakhamzimba, nezinye izinto ezibalulekile ngqo egazini. I-Shanghai TeamStandtandtandtandtandtation Corporation, umphakeli ochwepheshe kanye nomenzi weAmadivayisi wezokwelapha, ihlinzeka ngezinhlobo zombili zama-catheters. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-catheters kungasiza abachwepheshe bezempilo bakhethe idivaysi efanelekile yeziguli zabo.
Yini i-CVC?
A I-catheter yaseVenous Centrac(CVC), eyaziwa nangokuthi umugqa ophakathi nendawo, yi-tube ende, eguquguqukayo, eguquguqukayo efakwe ngomthambo entanyeni, esifubeni, noma ku-groin bese ethuthuka emithanjeni emiphakathi eseduze nenhliziyo. Ama-CVC asetshenziselwa izinhloso ezahlukahlukene, kufaka phakathi:
- Ukuphatha imishanguzo: Ikakhulu lezo ezicasulayo emithanjeni ephelele.
- Ukuhlinzeka nge-Intravenous yesikhathi eside (iv) ukwelashwa: okufana ne-chemotherapy, ukwelashwa okulwa namagciwane, kanye nenani lokudla kwabazali (i-TPN).
- Ukuqapha i-Central Venous Pressure: Ezigulini ezigula kakhulu.
- Ukudweba igazi ukuze kuhlolwe: lapho kudingeka isampula njalo.
Ama-CVCUngaba nama-lumens amaningi (iziteshi) ezivumela ukuphathwa ngasikhathi sinye izindlela zokwelapha ezahlukahlukene. Ngokuvamile zihloselwe ukufushane kokusetshenziswa okuphakathi nendawo, imvamisa kuze kube amasonto ambalwa, yize ezinye izinhlobo zingasetshenziswa isikhathi eside.
Iyini i-picc?
I-catheter ephakathi nendawo efakiwe (i-PICC) iwuhlobo lwe-catheter enkabeni efakwe ngomthambo we-peripheral, imvamisa engalweni engenhla, futhi yathuthuka kuze kube yilapho ithiphu lifinyelela emveni omkhulu eduze kwenhliziyo. Ama-PICC asetshenziselwa izinhloso ezifanayo nama-CVC, kufaka phakathi:
- Ukufinyelela okuhlala isikhathi eside kwe-IV: kaningi ezigulini ezidinga ukwelashwa okunwetshiwe njengokuphathwa kwama-chemotherapy noma isikhathi eside se-antibiotic.
- Ukuphatha imishanguzo: lokho kudinga ukulethwa maphakathi nenkathi yesikhathi eside.
- Ukudweba Igazi: Ukunciphisa isidingo sezinti eziphindaphindwayo.
Ama-PICC asetshenziswa ngokujwayelekile isikhathi eside kune-CVCS, imvamisa kusuka emavikini ambalwa kuya ezinyangeni. Ayihlaseli kangako kune-CVCS njengoba isayithi labo lokufaka liseveini ephelele kunokuba i-Central One.
Umehluko Osemqoka phakathi kwe-CVC ne-PICC
1. Indawo yokufaka:
- I-CVC: Ifakwe kwithambo eliphakathi, imvamisa entanyeni, esifubeni, noma ku-groin.
- I-PICC: Kufakwe emthanjeni we-peripheral engalweni.
2. Inqubo yokufaka:
- I-CVC: Ngokuvamile ifakwe endaweni elungiselelwe esibhedlela, imvamisa ngaphansi kwe-fluoroscopy noma ukuholwa kwe-ultrasound. Ngokuvamile kudinga izimo ezinyumba ngokwengeziwe futhi kuyinkimbinkimbi ngokwengeziwe.
- I-PICC: Ingafakwa embhedeni noma ekuhlelweni okungekho embhedeni, imvamisa ngaphansi kokuholwa kwe-ultrasound, okwenza inqubo ibe yinkimbinkimbi futhi ihlasele.
3. Isikhathi sokusetshenziswa:
- I-CVC: Ngokuvamile okuhloswe ngawo okufushane ekusetshenzisweni kwesikhathi esiphakathi (kuze kube amasonto ambalwa).
- I-PICC: Ilungele ukusetshenziswa kwesikhathi eside (amasonto kuya ezinyangeni).
4. Izinkinga:
- CVC: Ingozi ephezulu yezinkinga ezifana nokutheleleka, i-pneumothorax, kanye ne-thrombosis ngenxa yendawo ephakathi nendawo ye-catheter.
- I-PICC: Ingozi ephansi yezinkinga ezithile kepha isaqhubeka nezingozi ezifana ne-thrombosis, ukutheleleka, kanye ne-catheterclusion.
5. Induduzo yesineke nokuhamba:
- I-CVC: ingahle ibe ntofontofo ezigulini ngenxa yesayithi lokufaka kanye nethuba lokuvinjelwa kokunyakaza.
- I-PICC: Ngokuvamile kukhululekile ngokwengeziwe futhi kuvumela ukuhamba okukhulu kweziguli.
Ukugcina
Womabili ama-CVCs nama-PICC angamadivayisi abalulekile wezokwelapha anikezwe yiShanghai TeamStrate Inhlangano, ngayinye esebenza ngezidingo ezithile ngokususelwa esimweni sesiguli kanye nezidingo zokwelashwa. Ama-CVC akhethelwa ngokwezifiso zokwelashwa okunesikhathi esifushane nokuqapha, kanti ama-PICC athandwa ngokwelashwa isikhathi eside kanye nenduduzo yesiguli. Ukuqonda lokhu kwehluka kubalulekile kubahlinzeki bezokunakekelwa kwempilo ukwenza izinqumo ezinolwazi futhi banikeze ukunakekelwa okungcono kweziguli zabo.
