Isitofu sangoku soxinzelelo oluphezulu samkela indlela yokulawula inkqubo yekhompyuter.Ixhotyiswe ngeeseti ezininzi zeenkqubo zokutofa zamanqanaba amaninzi ezinokucengcelezwa.Zonke iisirinji ezinenaliti “ziyisirinji ezilahlwayo ezinoxinzelelo oluphezulu”, kwaye zixhotyiswe ngeetyhubhu ezidibanisa uxinzelelo, ezinokuskena kwaye zitofe iyeza ngaxeshanye.Ineenzuzo ze-automation ephezulu kunye nokuchaneka okuphezulu.Iyakwazi ukulungelelanisa izinga lokutofa ngokuthanda ngokweenxalenye ezahlukeneyo kunye neempawu ezahlukeneyo ze-pathological.Inokuthi ifake ngokukhawuleza i-agent echaseneyo kwi-arteries kunye ne-veins, esasazwa kwimithambo yegazi eyahlukeneyo.Ngexesha elifanayo lokutofa, inokwenza ukuskena kwe-CTA ukuphucula izinga lokuxilongwa kwezifo.
1. Indlela yokusebenza
Kwigumbi lokunyanga le-CT, sebenzisa i-2ml yesirinji ukufunxa i-2ml ye-0.9% yesisombululo se-NaCl, emva koko udibanise i-catheter ene-intravenous, sebenzisa i-G18-22 IV catheter ye-venipuncture, khetha izitya ezityebileyo, ezithe tye kunye ne-elastic ze-radial vein yelungu eliphezulu. , i-basilic vein, kunye ne-median cubital vein njenge-catheter ye-IV ye-puncture, ilungise ngokufanelekileyo emva kokuphumelela.Emva koko sebenzisa i-2ml yesirinji ukufunxa i-1ml ye-0.1% ye-meglumine diatrizoate i-agent echaseneyo ngenaliti emithanjeni.Jonga iziphumo zovavanyo emva kwemizuzu engama-20, Ukusabela okungalunganga: akukho kuqina kwesifuba okwethutyana, isicaphucaphu, i-urticaria, i-rhinitis, ibala eliqhelekileyo kunye neempawu ezibalulekileyo ziya kufakwa kwigumbi loviwo lweCT.Igumbi loviwo lwe-CT yi-Philips 16 row spiral CT, i-CT injector yoxinzelelo oluphezulu lwe-Shenzhen Antmed Co., Ltd., efaka i-Ossurol yeziyobisi.(1) Ngaphambi kokuba usebenze, vula iswitshi yamandla kwaye ufake iisirinji ezilahlwayo zoxinzelelo oluphezulu (iisirinji ezimbini).Isirinji A iphefumlela i-200ml ye-iodofol media, kunye nesirinji B iphefumlela i-200ml ye-0.9% yesisombululo se-sodium chloride.Xhuma iisirinji ezimbini kunye netyhubhu yokudibanisa iindlela ezintathu, ukhuphe umoya kwisirinji kunye netyhubhu, uze udibanise ne-catheter ye-intravenous yesigulane.Emva kokuba igazi litsalwe kakuhle kwakhona, beka intloko yesitofu phantsi ukuze ulinde.(2) Ngokobunzima obahlukeneyo besigulana kunye neendawo ezahlukeneyo zokuskena ezongeziweyo, inkqubo yokuchukumisa iqhutywa kwiscreen seLCD ukuseta isixa esipheleleyo kunye nesantya sokuhamba kwesisombululo senaliti kunye nenaliti ye-saline yesirinji yoxinzelelo oluphezulu.Isixa esipheleleyo sejoyi ye-iodoform yi-60-200 ml, inani elipheleleyo le-0.9% yesisombululo se-sodium chloride ngu-80-200 ml, kunye nesantya sokujova ngu-3 - 3.5 ml / s.Emva kokuba inkqubo igqityiwe, umqhubi wokuskena uya kukhupha umyalelo wokuqalisa inaliti.Okokuqala, i-iodoform media injected, hlambulula kwakhona nge-0.9% yesisombululo se-sodium chloride de ukuskena kugqitywe.

2. Amalungiselelo phambi kokuskena kweCTA
Buza isigulana ukuba sinayo nayiphi na imbali yokwaliwa kwamanye amayeza, i-hyperthyroidism, uxinzelelo lwegazi, isifo sentliziyo, isifo seswekile, ukusilela kwezintso, umthamo wegazi owaneleyo, i-hypoalbuminemia kunye nezinye izinto ezinobungozi obuphezulu be-angiography, kwaye uchaze injongo kunye nendima yokuskena okuphuculweyo. kwisigulana kunye nosapho lwakhe.Isigulana kufuneka sibe nesisu esingenalutho kwiiyure ezi-4 phambi kovavanyo oluphuculweyo lokuskena, kwaye abo baye bafumana i-barium meal fluoroscopy iintsuku ezi-3 ukuya kwezi-7 kodwa abazange bakhuphe i-barium abavumelekanga ukuba babe nesisu kunye ne-pelvic scanning.Xa usenza iskena se-CTA yesifuba kunye nesisu, kuyafuneka ukuba ubambe umoya wakho ukuze unciphise okanye uthintele ukungacwangciswanga kunye nezinto zakudala.Uqeqesho lokuphefumula kufuneka lwenziwe kwangaphambili kwaye ucelwe ukuba ubambe umoya wakho ekupheleni kokuphefumlelwa.
3. Yenza umsebenzi omhle wokunyamekela kwengqondo, kwaye uqalise kwizigulane ukuba uxinzelelo lwe-injection ye-injector yoxinzelelo oluphezulu lungaphezu koxinzelelo lokutyhala isandla, kwaye isantya sikhawuleza.Imithambo yegazi kwindawo yokutofa inokuwohloka, ibangele ukuvuza iyeza elingamanzi, ukudumba, ukuba ndindisholo, iintlungu, kwaye ezinye zinokukhula zibe sisilonda kunye ne-necrosis yezicubu.Okwesibini, xa utofa isitofu soxinzelelo oluphezulu, kukho ingozi enokubakho yokuba i-catheter yenaliti iya kuwa, okukhokelela ekuvuzeni kweyeza elingamanzi kunye nokulahleka kwedosi.Abasebenzi bobuhlengikazi besigulane baxelelwe kwakhona ukuba banokukhetha ngokucophelela i-vein efanelekileyo, basebenze ngokucophelela, kwaye bakhethe uhlobo olufanelekileyo lwe-catheter ye-IV ngokweemeko ze-vascular yesigulane.Xa usebenzisa i-injector yoxinzelelo oluphezulu, i-turnbuckles phakathi kwe-syringe barrel kunye ne-piston bolt yayiqinile, i-tube yokudibanisa yeendlela ezintathu yayidibaniswe ngokuqinileyo kunye ne-syringe kunye nazo zonke i-interfaces ze-catheter ye-IV, kunye nentloko yenaliti yayilungiswe ngokufanelekileyo.Ukuphelisa uvalo lwesigulana, fumana intsebenziswano, kwaye ekugqibeleni ucele amalungu osapho lwesigulana ukuba asayine ifomu yemvume enolwazi yokuskena iCTA.
4. Izilumkiso ngexesha lokuhlolwa kweCTA
1).Ukuthintela ukuvuza kweyeza elimanzi: xa iskena sihamba, ityhubhu yokudibanisa ayiyi kucudiswa okanye itsalwe, kwaye inxalenye yokubhoboza ayiyi kungqubana ukuze kuthintelwe ukuvuza kweyeza elimanzi.Emva kokumiselwa kweziko lokuskena, umongikazi kufuneka ahlole ukubekwa kwenaliti ye-catheter kwi-vein kwakhona, i-10 ~ 15ml ye-0.9% yesisombululo se-sodium chloride phantsi koxinzelelo oluphakathi ngesandla ukuze ubone ukuba ilungile, buza isigulane kwakhona nayiphi na. ukungonwabi njengeentlungu zokudumba kunye nokubetha, kwaye unike iingcebiso zengqondo ukuthuthuzela isigulane ukuba abasebenzi bezonyango baya kukunika ingqalelo ukususela ekuqaleni ukuya ekupheleni kokuskena, ukuze bakwazi ukumelana lula noviwo kunye nokuphelisa ukuxinana kunye noloyiko.Ngexesha lokutofa kwechiza, umongikazi kufuneka aqwalasele inkangeleko yobuso besigulana, ukuvuza kwechiza, ukuguquguquka kweziyobisi, njalo njalo. Ukuba kukho ingozi, inaliti kunye nokuskena kufuneka kuphazamiseke nangaliphi na ixesha.
I-2) Ukuthintela inaliti yomoya: Ukukhupha okungafanelekanga kuya kukhokelela kwi-air embolism.I-Air embolism yingxaki enkulu ngexesha lokuskena kwe-CTA, enokukhokelela ekufeni kwezigulana.Qaphela ngexesha lokusebenza.Zonke i-interfaces kufuneka ziqiniswe ukuze zithintele ukuhlukana phantsi koxinzelelo oluphezulu.Ngaphambi kokutofa, umoya kwiisirinji ezimbini, iityhubhu zokudibanisa iindlela ezintathu kunye neenaliti zecatheter kufuneka zikhutshwe.Ngexesha lokutofa, intloko yenaliti iba phantsi, ukuze amaqamza amancinci adada ukuya emsileni wesirinji.Isixa sokutofa singaphantsi komthamo weyeza elifakwe ngaphakathi kunye ne-0.9% yesisombululo se-sodium chloride.I-1 ~ 2ml yeyeza elimanzi kufuneka lihlale kwisirinji ukukhusela umoya ukuba ungacinezeleki kwimithambo yegazi yesigulane ngexesha lokutofa koxinzelelo oluphezulu.
I-3) Ukuthintela ukusuleleka kwisibhedlele esibhedlele: isigulane esinye, inaliti enye kunye neesirinji ezimbini kufuneka zifezekiswe xa kusenziwa ukuskena kwe-CTA, kwaye umgaqo wokusebenza oyinyumba kufuneka ulandelwe ngokungqongqo.
4) Isaziso emva kokuskena
a.Emva kokuskena, cela isigulana ukuba siphumle kwigumbi loqwalaselo, gcina i-catheter emithanjeni kangange-15 ~ 30min, kwaye uyikhuphe emva kokuba kungekho mpendulo igwenxa.Igumbi lonyango lwe-CT kufuneka lilungiswe kunye neyeza lokuqala kunye nezixhobo zoncedo lokuqala.Ukuba uziva ungaphilile, yiya kugqirha ngokukhawuleza ukukhusela ukwenzeka kokulibaziseka kwe-anaphylaxis kunye nemiphumo emibi.Isigulane saphinda sayalelwa ukuba sisele amanzi amaninzi ukukhuthaza ukukhutshwa kwe-agent echaseneyo ngokukhawuleza kunye nokunciphisa ukusabela okubi kwintso.
b.Kwi-CTA yokuskena, nangona ukusetyenziswa kwe-injector yoxinzelelo oluphezulu kunemingcipheko ethile, ikhuselekile, ithembekile kwaye inokudlala indima ekhethekileyo yekliniki kunye nemilinganiselo yokukhusela efanelekileyo yokuphepha ingozi.Kuyimfuneko kubuhlengikazi begumbi leCT langoku.Abasebenzi abongikazi kwigumbi leCT kufuneka babe nesimo sengqondo esingqongqo kunye nesinzulu xa besebenza.Kufuneka bathobele iinkqubo zokusebenza ze-injection ephezulu yoxinzelelo ngexesha lokusebenza.Kufuneka bajonge ngokuphindaphindiweyo amakhonkco amaninzi afana nokufunxa iziyobisi, ukukhupha, ukubhoboza kunye nokulungiswa ukuqinisekisa ukuba achanekile.Idosi yokutofa, isantya sokuhamba kunye nexesha lokutofa okuqhubekayo kufuneka lichaneke.Ukuqinisekisa ukuba izigulane zilugqiba ngempumelelo uviwo lweCTA.Ukusetyenziswa kwe-injector yoxinzelelo oluphezulu ekuhlolweni kwemifanekiso kunokuphucula amandla omgangatho wezilonda ezincinci kunye namatyala anzima, ukubonelela oogqirha ngokuxilongwa kwesifo kunye nesiseko sokuxilongwa, ukuphucula ukuchaneka kokuxilongwa kwesifo, kunye nokubonelela ngesiseko sonyango oluchanekileyo lokuxilongwa kwekliniki kunye nonyango.
