PICC: Nzira Yekubatsira Kurapwa Nemitsipa Kwenguva Refu

Kubva "kwete" Kupinda Kwemitsipa Yeropa"kusvika pa"kuboorwa kamwe chete kunovhura nzira" - nzira iyi iri kushandura mamiriro ekurapwa kwenguva refu kwemutsinga

Kune varwere vegomarara vari kurapwa chemotherapy, vanhu vanorwara zvakanyanya vanovimba nekudya kwenguva refu kwevabereki, uye avo vane zvirwere zvisingaperi zvinoda kurapwa kwenguva refu kwekudzivirira hutachiona, kuiswa muropa netsinga kunowanzoreva kudzokororwa kwetsinga dzeropa, kutsva kwakanyanya kwetsinga dzeropa, uye kunyange kuora mwoyo kwe "kusasara kwetsinga dzinosvikika." Nhasi, catheter yakatetepa inonzi PICC (inoiswa padivi penzira). Catheter yepakati) iri kuchinja chokwadi ichi chinyararire. Ichizivikanwa kwete se "nzira yehupenyu" chete, yave tekinoroji inokosha mukurapa kwemishonga yemazuva ano.

Katheta imwe chete inova sei "nzira yehupenyu"?

PICC i catheter refu, yakatetepa, inochinjika inopinzwa nemutsinga weropa (kazhinji muruoko rwepamusoro), ine muromo wayo pakupedzisira uri pachikamu chechitatu chezasi che superior vena cava kana cavoatrial junction (CAJ). Nzvimbo iyi ine kumhanya kweropa nekukurumidza mukufamba kweropa, ichideredza nekukurumidza mishonga yekurapa ine chemotherapeutic, maantibiotic, uye mishonga yekudya parenteral, nokudaro ichideredza zvakanyanya njodzi dze extravasation, phlebitis, thrombosis, uye hutachiona hune chekuita ne catheter. Zvidzidzo zvinoratidza kuti kutsauka kwemuromo we catheter kunogona kuwedzera njodzi ye thrombosis ne10-15% uye katatu njodzi yehutachiona hune chekuita ne catheter. Kunyatso shandiswa kwemuromo kunoratidza kubudirira uye kuchengetedzeka kwe "nzira iyi yehupenyu".

Zvichienzaniswa nepakati yechinyakare Catheter yemutsingas, PICC inopa mabhenefiti akanaka anosanganisira kugara kwenguva refu (kusvika pagore), njodzi shoma yekutapukirwa, uye nyore kuita mabasa ezuva nezuva. Chinonyanya kukosha ndechekuti inoderedza marwadzo ekuboorwa-boorwa kakawanda - semuenzaniso, varwere vegomarara vanowanzoda kuisirwa mutsinga katatu kusvika kana pasvondo; kuiswa kamwe chete kwePICC kunogona kutsigira nzira yese yekurapwa.

Kufambira mberi kwetekinoroji: kuita kuti "nzira yekubatsira" ive yakanyatsojeka uye yakangwara

Mumakore achangopfuura, matekiniki ePICC akachinja kubva pa "kuiswa panzvimbo isina kutariswa" kuenda ku "kutungamirirwa nemufananidzo" uye kubva pa "kusimbiswa kwemaitiro mushure mekuita" kuenda ku "kutungamira panguva chaiyo mukati mekuita." Kushandiswa kwetekinoroji ye electromagnetic navigation (kana magnetic tracking) kwakaunza nguva itsva yekuisa PICC nenzira chaiyo. Nekubatanidza kutungamira kwe ultrasound, electromagnetic tracking, uye intracavitary electrocardiography (IC-ECG), tekinoroji iyi inoratidza nzvimbo chaiyo uye nzira ye catheter pachiratidziro, zvichibvumira vashandi kugadzirisa kutadza kwetip panguva chaiyo panguva yekuita. Zvichienzaniswa ne X-ray yechipfuva mushure mekuisa, electromagnetic navigation inowana mukana wekutanga wekubudirira kusvika 100%, pasina kuratidzwa nemwaranzi, zvichiita kuti ive yakakodzera vana, vakwegura, vakadzi vane pamuviri, nevarwere vanorwara zvakanyanya.

Panguva imwe chete, zviratidzo zvePICC zviri kuramba zvichiwedzera. Kubva muna 2025, zvipatara zvakawanda muChina zvakabudirira kuita PICC placement kuburikidza ne inferior vena cava, zvichivhura nzira itsva yekupinda kune varwere vaimboonekwa se "vasina venous access" nekuda kwekuvharika kwevena cava kwakanyanya. Uyezve, kuwanikwa kwakapararira kwePICCs dzinopinza simba remajekiseni maviri emuviri (dual lumen PICCs) kunobvumira varwere kugamuchira mishonga miviri isingaenderane panguva imwe chete kuburikidza necatheter imwe chete uye zvakare kuedzwa kweCT kwakawedzerwa - kugona kwakakosha mukurapa kwakakwana kwevarwere vegomarara.

Kubva pakurapa chirwere kusvika pakuchengetedza hupenyu: kuchengetedza kwesainzi kunovaka nhoo yekuchengetedza

Kunyangwe PICC ichigona kuramba iripo kwenguva yakareba, haitombo "kukanganwa." Kugadziriswa kwakajairika, kwenguva dzose ndiko kwakakosha pakuwedzera hupenyu hwecatheter uye kuderedza matambudziko. Sekureva kwe2025 Expert Consensus on Clinical Maintenance of Intravenous Catheters yakapihwa neChinese Nursing Association, kugadziriswa kwePICC kunofanirwa kutevedzera mutemo wekuti "kamwe chete pamazuva manomwe", unoitwa nenyanzvi dzehutano dzakadzidziswa pasi pemamiriro asina utachiona, kusanganisira kuchinja mapfekero, kupukuta puru, uye kuchinja chivharo. Kugadziriswa kwakajairika kunogona kuderedza matambudziko ane chekuita necatheter neinopfuura 60%.

Kuti pave nedambudziko, maekisesaizi ekupomba maoko ekubata catheter (katatu kusvika katanhatu pazuva, ka25-30 nguva imwe neimwe) zvakaratidzwa kuti zvinovandudza kutenderera kweropa munharaunda uye zvinoderedza njodzi yethrombosis nehutachiona. Varwere vanofanirawo kuongorora nzvimbo yakaboorwa zuva nezuva kuti vaone kutsvuka, kuzvimba, kana exudate, uye vaone shanduko pakureba kwecatheter yekunze. Kana denderedzwa reruoko rwekubata catheter rikawedzera neanopfuura 2 cm zvichienzaniswa nerutivi rwemberi, tembiricha yemuviri ichikwira pamusoro pe38 °C, kana kuiswa kwacho kwakaoma, chiremba anofanira kutsvaga rubatsiro rwechimbichimbi.

Kupfuura tekinoroji: kunetseka kwakadzama nezvehupenyu hwemunhu

Ongororo yakaitwa muna 2025 yakaburitswa muPakistan Journal of Medical Sciences yakaratidza kuti pakati pevarwere vegomarara 119 vane PICC placement, huwandu hwezvinetso hwaive 11.2% chete muboka rekucherechedza raigamuchira ruremekedzo pamwe chete nekuyamwisa kwakavakirwa pauchapupu, zvichienzaniswa ne26.4% muboka rekurapa remazuva ose. Kuseri kwenhamba idzi kune chokwadi chiri nyore asi chakadzama: kunyangwe catheter iri diki, inokanganisa zvakanyanya manzwiro emuviri emurwere uye mamiriro epfungwa.

Mumwe murwere wegomarara rezamu akapihwa femoral PICC (nzira yepamusoro pemabvi) pakutanga akazeza uye akanetseka nezvenzira itsva yekuisira, asi pakupedzisira akawana rugare rwepfungwa runouya nekuisirwa zvinyoro nyoro uye akawanazve chivimbo mukurapwa kwake. Muzvipatara zvakawanda uye munzvimbo dzekuchengetwa kumba, "nzira yehupenyu" yePICC ine zvakawanda kupfuura basa remuviri rekupa mishonga netsinga - inoratidza ushingi hwemurwere hwekurwisa chirwere, kutevedzera kurapwa, uye tariro yekupora.

Kubva pa "nzira yehupenyu" kuenda ku "muitiro wekutarisira"

Nekuburitswa kwemagwaro emitemo akadai se2025 Expert Consensus on Clinical Maintenance of Intravenous Catheters, the Guidelines for the Use of Power injectable PICCs in Contrast-enhanced CT, uye Neonatal Bedside Ultrasound-guided PICC Insertion Guidelines, kushandiswa kwekiriniki kwetekinoroji yePICC kwapinda munguva itsva yekuenzanisa, kunyatsojeka, uye hunyanzvi hwakagadziriswa. Kubva kumadhipatimendi ekenza kusvika kumayuniti ekuchengetedza varwere zvakanyanya, kubva kuvacheche kusvika kune vakwegura, kubva pakuisirwa mishonga nguva dzose kusvika kuCT inokurudzirwa, PICC iri kutamba basa rakakosha munzvimbo dzakasiyana-siyana dzekiriniki.

Sezvakataurwa nenyanzvi munyaya iyi, “PICC haisi nzira yekuisira ropa kwenguva refu chete - inzira inochengetedza hupenyu zvechokwadi.” Kune avo vanoida zvakanyanya, katheta iyi diki, inofamba kubva paruoko ichienda pedyo nemoyo, inodzivirira chinyararire kurova kwemoyo kwetariro.

Chiziviso: Chinyorwa ichi ndechekuzivisa vanhu nezvekurapa chete uye hachisi zano renyanzvi rezvekurapa. Ndapota garai muchitevera zvirongwa zvekuongorora chirwere uye zvekurapa zvinopihwa nachiremba wenyu ari kurapa.
