Isingeniso
Ezweni lamadivayisi ezokwelapha,I-cannula ye-intravenous (IV)iyithuluzi elibalulekile elisetshenziswa ezibhedlela nasezikhungweni zezempilo ukuze kunikezwe uketshezi nemithi ngqo egazini lesiguli. Ukukhetha okulungileUsayizi we-IV cannulaKubalulekile ukuqinisekisa ukwelashwa okuphumelelayo kanye nenduduzo yesiguli. Lesi sihloko sizohlola izinhlobo ezahlukene zosayizi be-IV cannula, ukusetshenziswa kwazo, kanye nendlela yokukhetha usayizi ofanele izidingo ezithile zezokwelapha.I-TeamStandI-Corporation, umhlinzeki ohamba phambili we-imikhiqizo yezokwelapha elahlwayo, okuhlanganisa nama-cannula e-IV, ibilokhu ihamba phambili ekuhlinzekeni izixazululo ezisezingeni eliphezulu kochwepheshe bezokwelapha.
Izinhlobo ze-IV Cannula
Ama-cannula e-intravenous (IV) amadivayisi abalulekile ezokwelapha asetshenziselwa ukuletha uketshezi, imithi, noma izakhamzimba ngqo egazini lesiguli. Kuye ngesimo sezokwelapha, kusetshenziswa izinhlobo eziningana zama-cannula e-IV, ngalinye lisebenzela izinjongo ezithile. Ngezansi kunezinhlobo eziyinhloko:
1. I-Peripheral IV Cannula
I-Peripheral IV cannula iyindlela evame ukusetshenziswa ezibhedlela nasemakliniki. Ifakwa emithanjeni emincane yangaphandle, ngokuvamile ezingalweni noma ezandleni. Lolu hlobo lufanelekela ukwelashwa kwesikhashana, njengokuvuselela uketshezi, ama-antibiotic, noma ukuphathwa kobuhlungu. Kulula ukuyifaka nokuyikhipha, okwenza ifaneleke kakhulu ekusetshenzisweni okuphuthumayo nokuvamile.
2. I-Cannula Yomugqa Ophakathi IV
I-Central Line IV cannula ifakwa emthanjeni omkhulu, ngokuvamile entanyeni (umthambo wangaphakathi we-jugular), esifubeni (umthambo we-subclavian), noma esinqeni (umthambo we-femoral). Isihloko se-catheter siphelela ku-vena cava ephezulu eduze kwenhliziyo. Imigqa ephakathi isetshenziselwa ukwelashwa kwesikhathi eside (amasonto ambalwa noma inyanga), ikakhulukazi lapho kudingeka uketshezi oluningi, i-chemotherapy, noma ukudla okunempilo okuphelele (i-TPN).
3. Uhlelo lwe-Catheter oluvaliwe lwe-IV
Uhlelo lwe-catheter oluvaliwe, olwaziwa nangokuthi i-safety IV cannula, lwakhiwe ngethubhu yokwandisa enamathiselwe kusengaphambili kanye nezixhumi ezingenazinaliti ukuze kuncishiswe ingozi yokutheleleka kanye nokulimala kwenaliti. Luhlinzeka ngohlelo oluvaliwe kusukela ekufakweni kuya ekuphathweni koketshezi, okusiza ukugcina ukungazali kanye nokunciphisa ukungcola.
4. I-Midline Catheter
I-Midline catheter uhlobo lwedivayisi ye-peripheral IV efakwa emthanjeni ongakwesokunene futhi iqhubekele phambili ukuze inhloko ilale ngaphansi kwehlombe (ingafinyeleli emithanjeni ephakathi). Ifanele ukwelashwa kwesikhathi esiphakathi—ngokuvamile kusukela evikini elilodwa kuya kwamane—futhi ivame ukusetshenziswa lapho kudingeka ukufinyelela njalo kwe-IV kodwa umugqa ophakathi ungadingeki.

Ukusetshenziswa kosayizi be-IV Cannula
1. Umuthi Ophuthumayo:
- Ezimweni eziphuthumayo, ama-cannula amakhulu e-IV (14G kanye ne-16G) asetshenziselwa ukuletha uketshezi nemithi ngokushesha.
2. Ukuhlinzwa kanye ne-Anesthesia:
- Ama-cannula e-IV aphakathi nendawo (18G kanye no-20G) avame ukusetshenziswa ngesikhathi sokuhlinzwa ukuze kulondolozwe ibhalansi yoketshezi kanye nokunikeza i-anesthesia.
3. Udokotela Wezingane kanye Nodokotela Abakhulile:
- Ama-cannula amancane e-IV (22G kanye no-24G) asetshenziswa ezinsaneni, ezinganeni, kanye neziguli ezindala ezinemithambo ethambile.
Indlela Yokukhetha Usayizi We-IV Cannula Ofanele
Ukukhetha usayizi we-IV cannula ofanele kudinga ukucatshangelwa ngokucophelela isimo sesiguli kanye nezidingo zezokwelapha:
1. Khetha Usayizi we-IV Cannula kanye nombala ngokuya ngeminyaka
| Amaqembu | Osayizi be-IV Cannula abanconyiwe | |
| Izinsana kanye nezinsana ezisanda kuzalwa (unyaka ongu-0-1 ubudala) | 24G (ophuzi), 26G (onsomi) | Imithambo mincane kakhulu yezingane ezisanda kuzalwa. Ama-cannula amancane ayathandwa. |
| Izingane (iminyaka eyi-1-12 ubudala) | 22G (oluhlaza okwesibhakabhaka), 24G (ophuzi) | Imithambo iba mikhulu njengoba ikhula, i-22G kanye ne-24G zivame ukusetshenziswa |
| Intsha (iminyaka engu-13-18 ubudala) | 20G (opinki), 22G (oluhlaza okwesibhakabhaka) | Imithambo yentsha ivaliwe kubantu abadala, i-20G ne-22G ziyafaneleka. |
| Abantu abadala (abaneminyaka engu-19+ ubudala) | 18G (oluhlaza okotshani), 20G (opinki), 22G (oluhlaza okwesibhakabhaka) | Kwabantu abadala, ukukhethwa kosayizi we-iv cannula kuyahlukahluka kuye ngezinqubo kanye nosayizi wemithambo. Osayizi abavame ukusetshenziswa kakhulu yi-18G, 20G, 22G. |
| Iziguli Ezikhulile (ezineminyaka engu-60+ ubudala) | 20G (opinki), 22G (oluhlaza okwesibhakabhaka) | Njengoba imithambo yegazi ingase ibe buthakathaka kakhulu njengoba ikhula, ubukhulu be-cannula obufanele bubaluleke kakhulu ukuze kuncishiswe ukungakhululeki kanye nengozi yezinkinga. Ama-cannula asukela ku-20 kuya ku-22 gauge avame ukusetshenziswa. |
Ezinye Izinto Ezibalulekile Ezibalulekile Okumelwe Zicatshangelwe
Ukucabangela ubukhulu bemithambo yeziguli kuyisiqalo esiwusizo kodwa kunezici ezengeziwe okufanele uzicabangele lapho ukhetha ubukhulu be-cannula ye-IV efanele:
Izimo zezokwelapha zesiguli:Kunezimo ezithile ezingase zithinte ukukhethwa kosayizi we-cannula. Isibonelo, iziguli ezinemithambo ebuthakathaka zingadinga usayizi omncane.
Okuhlangenwe nakho kochwepheshe bezempilo:Indlela yokufaka kanye nolwazi lochwepheshe nakho kudlala indima ebalulekile.
Uhlobo lokwelashwa nge-IV:Uhlobo loketshezi kanye nemithi enikezwayo kuthinta ukukhetha usayizi
Izinhlobo ezidumile ze-IV Cannula
1. i-IV Cannula elahlwayo
2. i-cannula yokuphepha ye-IV
3. I-IV Cannula ene-injection port
Isiphetho
Ama-cannula e-IV angamathuluzi abalulekile ekunakekelweni kwezempilo kwesimanje, okwenza ochwepheshe bezokwelapha bakwazi ukunikeza uketshezi nemithi ngqo egazini lesiguli. I-Shanghai Team Stand Corporation, umhlinzeki odumile wemikhiqizo yezokwelapha elahlwayo, kufaka phakathi ama-cannula e-IV, izibophezele ekuhlinzekeni izixazululo ezisezingeni eliphezulu kubahlinzeki bezempilo emhlabeni jikelele. Lapho ukhetha usayizi we-cannula ye-IV ofanele, kubalulekile ukucabangela ubudala besiguli, isimo, kanye nezidingo ezithile zezokwelapha ukuqinisekisa imiphumela yokwelashwa efanele kanye nenduduzo yesiguli. Ngokuqonda izinhlobo ezahlukene zeUsayizi we-cannula ye-IVkanye nezicelo zabo, ochwepheshe bezokwelapha bangathuthukisa ikhono labo lokunikeza ukunakekelwa kweziguli okuphumelelayo nokuphumelelayo.
