Embolic Microspheres ndeye compressible hydrogel microspheres ine chimiro chenguva dzose, yakatsetseka pamusoro, uye saizi yakarongedzerwa, iyo inoumbwa semhedzisiro yekugadziriswa kwemakemikari pane polyvinyl doro (PVA) zvinhu.Embolic Microspheres ine macromer inotorwa kubva ku polyvinyl doro (PVA), uye ndeye hydrophilic, isingadzokeke, uye inowanikwa muhukuru hwakasiyana.Mushonga wekuchengetedza ndeye 0.9% sodium chloride solution.Iyo mvura yemukati yakazara polymerized microsphere ndeye 91% ~ 94%.Microspheres inogona kushivirira compression ye30%.
Embolic Microspheres inotarisirwa kushandiswa kumisa arteriovenous malformations (AVMs) uye hypervascular tumors, kusanganisira uterine fibroids.Nekuvharira kupihwa kweropa kunzvimbo yakatariswa, bundu kana malformation inoziya nenzara uye inoderera muhukuru.
Muchikamu chino, tinokuratidza nhanho dzakadzama dzemashandisiro eEmbolic Microspheres.
Kugadzirira zvinhu
Zvakakosha kugadzirira 1 20ml sirinji, 2 10ml majekiseni, 3 1ml kana 2ml majekiseni, nzira nhatu, chigero chekuvhiya, kapu isina utachiona, chemotherapy mishonga, embolic microspheres, musiyano midhiya, uye mvura yejekiseni.
Danho 1: Gadzira chemotherapy mishonga
Shandisa chigero chekuvhiya kuburitsa bhodhoro remushonga wemotherapeutic uye wodira mushonga wechemotherapeutic mukapu isina utachiona.
Rudzi uye chiyero chemishonga chemotherapeutic zvinoenderana nezvinodiwa zvekiriniki.
Shandisa mvura yejekiseni kuti uparadze chemotherapy mishonga, uye iyo yakakurudzirwa yekuisa inodarika 20mg/ml.
Amushure mekunge mushonga wechemotherapeutic wanyungudika zvakazara, mushonga wechemotherapeutic drug wakatorwa nesirinji ye10ml.
Danho 2: Kubviswa kwemishonga inotakura embolic microspheres
Iwo embolized microspheres akazununguswa zvizere, akapinzwa mujekiseni tsono kuenzanisa kudzvanywa mubhodhoro,uye bvisa mhinduro uye microspheres kubva mubhodhoro recillin ine 20ml sirinji.
Rega sirinji imire kwemaminitsi 2-3, uye mushure mokunge ma microspheres agara, iyo supernatant inodzingwa kunze kwemhinduro.
Nhanho 3: Isa mishonga yeChemotherapeutic muEmbolic Microspheres
Shandisa iyo 3 nzira stopcock kubatanidza sirinji ne embolic microsphere uye sirinji ine chemotherapy drug, teerera kune yakabatana zvakasimba uye mafambiro ekuyerera.
Sunda sirinji yemushonga wechemotherapy neruoko rumwe, wodhonza sirinji ine embolic microspheres nerumwe ruoko.Pakupedzisira, chemotherapy drug uye microsphere zvinosanganiswa mu 20ml sirinji, zunza sirinji zvakanaka, uye uisiye kwemaminitsi makumi matatu, zunza maminitsi mashanu ega panguva.
Danho 4: Wedzera musiyano midhiya
Mushure mokunge ma microspheres akatakurwa nemishonga ye chemotherapeutic kwemaminitsi makumi matatu, huwandu hwekugadzirisa hwakaverengwa.
Wedzera 1-1.2 nguva yevhoriyamu yekusiyanisa mumiririri kuburikidza nenhatu nzira stopcock, zunza zvakanaka uye rega kumira kwemaminitsi mashanu.
Nhanho yechishanu: Microspheres inoshandiswa mukuita kweTACE
Kuburikidza nenzira nhatu stopcock, jekiseni ingangoita 1ml yemamicrospheres musirinji ye1ml.
Ma microspheres akaiswa mu microcatheter ne pulsed injection.
Guides attentions:
Ndokumbira utarise kushandiswa kweaseptic.
Simbisa kuti mishonga yechemotherapeutic inonyungudika zvachose usati waisa mishonga.
Iko kusanganiswa kwechemotherapy zvinodhaka kuchakanganisa iyo dhizaini yekurodha maitiro, iyo yakanyanya kuwanda, iyo inokurumidza iyo adsorption chiyero, inokurudzirwa yekurodha zvinodhaka haisi pasi pe20mg/ml.
Mvura isina utachiona chete yejekiseni kana 5% glucose jekiseni inofanira kushandiswa kunyungudutsa chemotherapy mishonga.
Muyero wekunyungudika kwedoxorubicin mumvura isina utachiona hwejekiseni waimhanya zvishoma kudarika 5% jekiseni reglucose.
5% jekiseni reglucose rinonyungudutsa pirarubicin nekukurumidza zvishoma pane mvura isina utachiona yekubaya jekiseni.
Kushandiswa kweioformol 350 sepakati pekusiyanisa kwaive kwakanakira kumiswa kwemamicrospheres.
Kana ijekiseni mubundu kuburikidza ne microcatheter, jekiseni repulse rinoshandiswa, iro rinonyanya kubatsira kune microsphere suspension.
