Microspheres za Embolic ni microspheres za hydrogel zishobora gukubanywa zifite ishusho isanzwe, ubuso bworoshye, n'ingano igenwa, zikorwa bitewe n'impinduka mu bya shimi ku bikoresho bya polyvinyl alcohol (PVA). Microspheres za Embolic zigizwe na macromer ikomoka kuri polyvinyl alcohol (PVA), kandi zikunda amazi, ntizishobora gukurwamo, kandi ziboneka mu bunini butandukanye. Umuti wo kubungabunga ni 0.9% ya sodium chloride. Amazi ya microsphere yuzuye polymer ni 91% ~ 94%. Microspheres zishobora kwihanganira gukuba kwa 30%.
Uduce twa Embolic Microspheres tugamije gukoreshwa mu gukuraho ubumuga bw'imitsi itera imitsi (AVM) n'ibibyimba by'imitsi itera amaraso menshi, harimo n'udukoko twa fibroids two mu mura. Mu kubuza amaraso kugera aho agenewe, ikibyimba cyangwa ubumuga burabura intungamubiri kandi bugagabanuka mu bunini.
Muri iyi nkuru, turakwereka intambwe zirambuye ku buryo bwo gukoresha Embolic Microspheres.
Gutegura ibicuruzwa
Ni ngombwa gutegura seringi 1 ya mililitiro 20, seringi 2 za mililitiro 10, seringi 3 za mililitiro 1 cyangwa 2, imikasi yo kubaga, igikombe cya sterile, imiti ya chimiotherapie, embolic microspheres, contrast media, n'amazi yo gutera.
Intambwe ya 1: Gushyiraho imiti ya chimiotherapie
Koresha imikasi yo kubaga kugira ngo ukuremo icupa ry'umuti uvura kanseri hanyuma usuke umuti uvura kanseri mu gikombe kitarimo umwanda.
Ubwoko n'ingano y'imiti ivura indwara za chimiotherapeutic biterwa n'ibyo ikeneye mu buvuzi.
Koresha amazi mu gutera inshinge kugira ngo ushongeshe imiti ya chimiotherapie, kandi igipimo cyagenwe ni kirenga 20mg/ml.
ANyuma y'uko umuti wa chimiotherapeutic ushongeshejwe burundu, umuti wa chimiotherapeutic wakuwemo hakoreshejwe seringe ya mililitiro 10.
Intambwe ya 2: Gukuramo utunyangingo tw’imitsi dutwara imiti
Uduce duto twashyizwemo imyobo twazungurutswe neza, dushyirwa mu rushinge rwa syringe kugira ngo umuvuduko w'icupa ungane,hanyuma ukuremo umuti n'udupira duto mu icupa rya cillin ukoresheje seringe ya mililitiro 20.
Reka syringe ihagarare iminota 2-3, hanyuma iyo mikorosifero zimaze guhagarara, supernatant isunikwa iva mu gisubizo.
Intambwe ya 3: Shyira imiti ya Chimotherapeutic muri Embolic Microspheres
Koresha uburyo butatu bwa stopcock kugira ngo uhuze syringe na microsphere ya embolic na syringe n'umuti wa chimiotherapie, witondere isano iri hagati yayo neza n'icyerekezo cy'inzira.
Sunika syringe y'imiti ya chimiotherapie n'ukuboko kumwe, hanyuma ukure syringe irimo mikorosfero za embolic n'ukuboko kumwe. Amaherezo, umuti wa chimiotherapie n'imikorosfero bivangwa muri syringe ya mililitiro 20, uzunguze syringe neza, hanyuma ubirekere iminota 30, ubizunguze buri minota 5 muri icyo gihe.
Intambwe ya 4: Ongeraho uburyo bwo gutandukanya ibintu (contrast media)
Nyuma y'uko imiyoboro mito yuzuyemo imiti ivura indwara za chimiotherapeutic mu gihe cy'iminota 30, ingano y'umuti yarabazwe.
Ongeraho inshuro 1-1.2 z'ingano y'ikintu gitandukanya ibintu ukoresheje stopcock y'inzira eshatu, uzunguze neza hanyuma ureke bihagarare iminota 5.
Intambwe ya 5: Mikorosfero zikoreshwa muri gahunda ya TACE
Unyuze muri stopcock y'inzira eshatu, shyiramo mikorosferi zigera kuri 1ml muri syringe ya 1ml.
Utu duce duto twashyizwe muri microcatheter hakoreshejwe uburyo bwa pulsed injection.
Iyobora abantu kwita ku byo umuntu ashaka:
Nyamuneka menya neza ko imikorere y'ibinyabutabire idafite aside.
Emeza ko imiti ivura indwara za chimiotherapeutic yashongeshejwe burundu mbere yo kuyishyiramo.
Ubwinshi bw'imiti ya chimiotherapie buzagira ingaruka ku musaruro w'imiti, uko umubare wayo wiyongera, niko umuvuduko wayo wihuta, ubwinshi bw'imiti busabwa ntabwo buri munsi ya 20mg/ml.
Amazi yanduye yo guterwa mu gutera cyangwa gutera isukari ya 5% ni yo yonyine agomba gukoreshwa mu gushonga imiti ya chimiotherapie.
Igipimo cyo gushonga kwa doxorubicin mu mazi yanduye mu gutera cyari cyihuta gato kuruta 5% by'inshinge za glucose.
Gutera 5% bya glucose bishongesha pirarubicin vuba gato kurusha amazi yanduye yo guterwa.
Gukoresha ioformol 350 nk'uburyo bwo kugereranya ibintu byafashije cyane mu guhagarika microspheres.
Iyo utewe muri iki kibyimba ukoresheje microcatheter, uterwa pulse injection, ibyo bikaba byoroshye cyane kugira ngo microsphere suspension irusheho kuba nziza.
