Yemazuva ano yepamusoro yekudzvanya jekiseni inotora komputa chirongwa chekudzora maitiro.Iyo inoshongedzerwa nemaseti akawanda eakawanda-nhanho jekiseni zvirongwa zvinogona kudzokororwa nemusoro.Ese majekiseni majekiseni “anoraswa akanyanya kudzvanywa majekiseni”, uye akashongedzerwa ane pressure yekubatanidza machubhu, anogona kuongorora nekubaya mushonga panguva imwe chete.Iyo ine mabhenefiti epamusoro otomatiki uye yakakwirira kunyatso.Inogona kugadzirisa jekiseni chiyero pamadiro zvichienderana nezvikamu zvakasiyana uye zvakasiyana pathological properties.Inogona kukurumidza jekiseni musiyano mumiririri mutsinga uye tsinga, izvo anoparadzirwa siyana tsinga ropa.Panguva imwechete yejekiseni, inogona kuita CTA scanning kuti ivandudze kuongororwa kwezvirwere.
1. Nzira yekushanda
Mukamuri yekurapisa yeCT, shandisa sirinji ine 2ml kuyamwa 2ml ye0.9% NaCl solution, wozobatanidza catheter inopinza, shandisa G18-22 IV catheter ye venipuncture, sarudza midziyo yakakora, yakatwasuka uye elastic yeradial tsinga yegumbo repamusoro. , the basilic vein, uye median cubital vein seIV catheter yekubaya, zvigadzirise zvakanaka mushure mekubudirira.Uye woshandisa sirinji ine 2ml kuyamwa 1ml ye0.1% meglumine diatrizoate difference agent kuburikidza nejekiseni remutsinga.Tarisa mhinduro dzebvunzo 20 maminetsi gare gare, Negative reaction: hapana kupfupika kwechipfuva, kusvotwa, urticaria, rhinitis, uye yakajairika ruvara uye zviratidzo zvakakosha zvichaiswa mukamuri yekuongororwa kweCT.Kamuri yekuongorora yeCT iPhilips 16 row spiral CT, yakanyanya kudzvanywa CT jekiseni yeShenzhen Antmed Co., Ltd., inobaya mushonga weOssurol.(1) Usati washanda, batidza switch yemagetsi uye isa inoraswa high pressure sirinji (masirinji maviri).Sirinji A inofema 200ml yeiodofol media, uye sirinji B inofema 200ml ye0.9% sodium chloride solution.Batanidza majekiseni maviri nechubhu yenzira nhatu, buritsa mweya musirinji nechubhu, wozobatanidza nekatheta yemurwere.Mushure mekunge ropa radhonzwa zvakanaka zvakare, isa jekiseni musoro pasi kuitira kumira.(2) Zvinoenderana nehuremu hwakasiyana hwemurwere uye nzvimbo dzakasiyana dzakakwidziridzwa dzekuongorora, kubata chirongwa kunoitwa pachiratidziro cheLCD kuseta huwandu hwakazara uye kuyerera kwejekiseni rejekiseni uye jekiseni resaline repamusoro-soro sirinji.Huwandu hwejekiseni reiodoform 60-200 ml, huwandu hwe0.9% sodium chloride solution ndeye 80-200 ml, uye jekiseni re3 - 3.5 ml/s.Mushure mekunge chirongwa chapera, mushandisi wekutarisa anoburitsa murairo wekutanga jekiseni.Chekutanga, iodoform media inobayiwa, sukurudza zvakare ne 0.9% sodium chloride solution kusvika kuvheneka kwapera.

2. Kugadzirira pamberi peCTA scanning
Bvunza murwere kana ane nhoroondo yekusawirirana kune mamwe madhiragi, hyperthyroidism, hypertension, chirwere chemwoyo, chirwere cheshuga nephropathy, renal insufficiency, ropa risina kukwana, hypoalbuminemia nezvimwe zvinhu zvine ngozi ye angiography, uye tsanangura chinangwa nebasa rekuwedzera kuongorora. kumurwere nemhuri yake.Murwere anofanira kuva nedumbu risina chinhu kwemaawa mana asati avandudzwa kuongorora kuongorora, uye avo vakawana barium meal fluoroscopy kwemazuva matatu kusvika ku7 asi vasati vabudisa barium havabvumirwi kuve nedumbu uye pelvic scanning.Paunenge uchiita CTA scanning yechipfuva nedumbu, zvinodikanwa kubata mweya wako kudzikisa kana kudzivirira zvisiri stratification uye zvigadzirwa.Kudzidzira kufema kunofanirwa kuitwa pachine nguva uye kukumbirwa kubata mweya wako pakupera kwekufemerwa.
3. Ita basa rakanaka rekuchengetedza mupfungwa, uye zivisa kuvarwere kuti kumanikidzwa kwejekiseni yejekiseni yepamusoro yakakura kudarika kudzvinyirira kwemaoko, uye kukurumidza kunokurumidza.Mitsipa yeropa panzvimbo yejekiseni inogona kudonha, zvichikonzera kubuda kwemushonga wemvura, edema, kusanzwa, kurwadziwa, uye mamwe anogona kuita maronda uye tishu necrosis.Chechipiri, pakubaya jekiseni repamusoro-soro, pane njodzi inogona kuitika yekuti jekiseni catheter inodonha, zvichikonzera kubuda kwemushonga wemvura uye kurasikirwa kwedosi.Vashandi vanoyamwisa murwere vakaudzwawo kuti vaigona kunyatsosarudza mutsinga wakakodzera, kushanda zvakanyatsonaka, uye kusarudza rudzi rwakakodzera rwe IV catheter maererano nemurwere wevascular condition.Paunenge uchishandisa iyo high pressure injector, turnbuckles pakati pesirinji barrel uye piston bolt yakanga yakasimba, iyo nzira nhatu yekubatanidza chubhu yakanga yakanyatsobatanidzwa nesirinji uye zvose zvinopindirana zve IV catheter, uye musoro wetsono wakanyatsogadziriswa.Bvisa kutya kwemurwere, wana kushandira pamwe, uye pakupedzisira kumbira nhengo dzemhuri yemurwere kusaina fomu remvumo rine ruzivo rweCTA scanning.
4. Kuchengetedza panguva yekuongorora kweCTA
1).Kudzivirirwa kwekudonha kwemushonga wemvura: kana scanner ichifamba, iyo yekubatanidza chubhu haifanirwe kusvinwa kana kudhonzwa, uye chikamu chekupinza hachifanirwe kubonderana kudzivirira kubuda kwemushonga wemvura.Mushure mekutemerwa kwenzvimbo yekuongorora, mukoti anofanirwa kutarisa kuiswa kwetsono yekatheter mutsinga zvakare, jekiseni 10 ~ 15ml ye0.9% sodium chloride solution pasi pekumanikidzwa kuri pakati nepakati kuti aone kana yakatsetseka, bvunza murwere zvakare chero kusagadzikana kwakadai sekurwadziwa kwekuzvimba uye palpitation, uye kupa mazano epfungwa kunyaradza murwere kuti vashandi vezvokurapa vachakuteerera kubva pakutanga kusvika pakuguma kwekuongorora, kuitira kuti vagone kurarama nekuongorora uye kubvisa kushushikana uye kutya.Panguva yejekiseni remushonga, mukoti anofanira kunyatsocherechedza chiso chemurwere, kubuda kwezvinodhaka, kusawirirana kwezvinodhaka, nezvimwewo. Kana pakaitika tsaona, jekiseni uye kuvheneka zvinofanira kumbomiswa chero nguva.
2) Kudzivirira jekiseni remhepo: Kupera kusina kunaka kunotungamira kumhepo embolism.Air embolism idambudziko rakakomba panguva yeCTA scanning, izvo zvinogona kutungamirira kurufu rwevarwere.Ngwarira panguva yekushanda.Yese mainterfaces anofanirwa kusimbiswa kuti adzivise kupatsanurwa pasi pekumanikidza kwakanyanya.Pamberi pejekiseni, mweya uri mumajekiseni maviri, nzira nhatu dzekubatanidza machubhu uye tsono dzecatheter dzinofanirwa kubviswa.Panguva yejekiseni, musoro wejekiseni unodzika pasi, zvekuti mamwe mabhuru madiki anoyangarara kusvika kumuswe wesirinji.Huwandu hwejekiseni hushoma pane huwandu hwemushonga wakafemerwa uye 0.9% sodium chloride mhinduro.1 ~ 2ml yemushonga wemvura unofanirwa kuramba uri mujekiseni kudzivirira mweya kubva pakudzvanywa mutsinga dzeropa remurwere panguva yejekiseni repamusoro.
3) Kudzivirirwa kwehutachiwana hwemuchinjikwa muchipatara: murwere mumwe, tsono imwe uye imwe majekiseni maviri anofanira kuwanikwa paunenge uchiita CTA scanning, uye sterile operation musimboti inofanira kunyatsoteverwa.
4) Chiziviso mushure mekuongorora
a.Mushure mekuongorora, kumbira murwere kuti azorore muimba yekucherechedza, chengetedza catheter ye intravenous kwe 15 ~ 30min, uye ibudise kunze mushure mokunge pasina kukanganisa.Imba yekurapisa yeCT inofanirwa kugadzirirwa nemushonga wekutanga uye nemidziyo yekubatsira yekutanga.Kana iwe uchinzwa usina kunaka, enda kuna chiremba pakarepo kudzivirira kuitika kwekunonoka anaphylaxis nemigumisiro yakaipa.Murwere akarayirwawo kunwa mvura yakawanda kuti akurudzire kubuda kwemufananisi wekusiyanisa nekukurumidza uye kuderedza kukanganisa kwakashata kune itsvo.
b.MuCTA scanning, kunyangwe kushandiswa kweiyo high pressure jekiseni kune dzimwe njodzi, yakachengeteka, yakavimbika uye inogona kuita yakasarudzika basa rekiriniki nematanho akakodzera ekudzivirira kudzivirira njodzi.Izvo zvinofanirwa kune yemazuva ano CT room mukoti.Vashandi vehukoti mukamuri yeCT vanofanirwa kuve nehunhu hwakasimba uye hwakakomba kana vachishanda.Vanofanira kutevedzera maitiro ekushanda epamusoro-soro majekiseni panguva yekushanda.Vanofanira kudzokorodza kutarisa zvakawanda zvinongedzo senge kusveta zvinodhaka, kupera simba, puncture uye kugadzirisa kuti vaone kuti ndezvechokwadi.Iyo jekiseni dose, chiyero chekuyerera uye inoenderera nguva jekiseni inofanirwa kuve yakarurama.Kuti uve nechokwadi chekuti varwere vanopedza bvunzo dzeCTA.Kushandiswa kwejekiseni yepamusoro-soro mukuongorora kwekufungidzira kunogona kuvandudza kukwanisa kwezvipembenene zviduku uye nyaya dzakaoma, kupa vanachiremba chirwere chekuongorora chirwere uye kusiyanisa kuongororwa nheyo, kuvandudza kurongeka kwekuongororwa kwechirwere, uye kupa humwe hutano hwakakwana hwekurapa kwekliniki kuongororwa uye kurapwa.
Kuti uwane rumwe ruzivo nezve zvigadzirwa nemasevhisi edu, ndapota taura nesu painfo@antmed.com.
