Uma kuqhathaniswa nomjovo wezandla wendabuko, umjovo wengcindezi ephezulu unezinzuzo zokuzenzakalela, ukunemba nokunye.Kancane kancane iye yashintsha indlela yokujova okwenziwa ngesandla futhi yaba ngomunye wemishini edingekayo yokuskena okuthuthukisiwe kwe-magnetic resonance (MR).Lokhu kudinga ukuthi silawule ubuchwepheshe bayo bokusebenza ukuze senze kahle kule nqubo.
1 Ukuhlinzwa komtholampilo
1.1 Inhloso evamile: Ukuskena kwe-MR okuthuthukisiwe kwezifo kufaka phakathi izimila, okusolakala ukuthi zinezilonda emkhathini noma izifo zemithambo.
1.2 Izinto zokusebenza nezidakamizwa: Isijovo esinengcindezi ephezulu esetshenziswa umnyango wethu i-ImaStar MDP MR injector ekhiqizwa yi-Antmed.Yakhiwe ngekhanda lomjovo, ikhompuyutha yokusingatha kanye nekhonsoli enesikrini sokuthinta esibukwayo.I-ejenti yokuqhathanisa ingeyasekhaya futhi ingenisiwe.Umshini we-MR iyi-3.0T superconducting yonke i-MR scanner ekhiqizwa yi-PHILIPS Company.
Inkampani Shenzhen Antmed Co., Ltd. I-ImaStar MRI Dual Head Contrast Media Delivery System:
1.3 Indlela yokusebenza: Vula isiphakeli sikagesi, beka iswishi yamandla ngakwesokudla sengxenye yegumbi lokusebenza endaweni ON.Ngemuva kokuthi ukuzihlola komshini sekuqediwe, uma imitha yenkomba yokucwayiza isesimweni sokulungele ukujovwa, faka isirinji ye-MR ephezulu yokucindezela ekhiqizwe i-Antmed], enesirinji engu-A, isirinji engu-B kanye neshubhu yokuxhuma ye-T enamathiselwe ngaphakathi. .Ngaphansi kwezimo eziqinile zokusebenza kwe-aseptic, phendulela ikhanda lomjovo phezulu, qaqa ikhava eyisivikelo ekugcineni kwesirinji, Chofoza inkinobho eya phambili ukuze uphushe ipiston iye phansi, bese udweba u-30~45 ml we-ejenti yokuqhathanisa eshubhu “A”. , kanye nenani likasawoti ovamile elisuka kushubhu elithi “B” liyalingana noma likhulu kunenani le-ejenti yokuqhathanisa.Phakathi nale nqubo, qaphela ukukhipha umoya kusipetu, ukuxhuma ishubhu lokuxhuma i-T nenaliti, futhi uqhube ukubhoboza kwe-venous ngemva kokukhathala.Kubantu abadala, jova u-0.2~0.4 ml/kg we-ejenti yokuqhathanisa, futhi ezinganeni, jova u-0.2~3 ml/kg we-ejenti yokuqhathanisa.Ijubane lomjovo ngu-2 ~ 3 ml/s, futhi wonke ajovwe emthanjeni wendololwane.Ngemuva kokubhoboza i-venous ngempumelelo, Vula i-KVO (gcina i-vein ivuliwe) ekhasini lasekhaya lesikrini ukuze uvimbele ukuvaleka kwegazi, buza indlela isiguli esisabela ngayo, bhekisisa indlela isiguli esisabela ngayo emuthini, uqede ukwesaba kwesiguli, bese uthumela isiguli ngokucophelela. uzibuthe uye endaweni yokuqala, sebenzisana nomsebenzisi, jova i-ejenti yokuqhathanisa kuqala, bese ujova usawoti ovamile, bese uskena ngokushesha.Ngemuva kokuskena, zonke iziguli kufanele zihlale imizuzu engama-30 ukuze zibheke ukuthi akukho yini ukungezwani komzimba ngaphambi kokuhamba.
2 Imiphumela
Ukubhoboza ngempumelelo kanye nomjovo wezidakamizwa kwenza ukuhlolwa kwe-MR okuthuthukisiwe kokuskena kuqedwe ngempumelelo ngokohlelo oluhleliwe, futhi kutholwe imiphumela yokuhlolwa kwezithombe ngenani lokuxilonga.
3 Ingxoxo
3.1 Ubuhle bomjovo wengcindezi ephezulu: Umjovo wengcindezi ephezulu uklanyelwe ngokukhethekile umjovo we-ejenti yokuqhathanisa ngesikhathi sokuskena okuthuthukisiwe kwe-MR ne-CT.Ilawulwa ikhompuyutha enezinga eliphezulu lokuzenzakalela, ukunemba nokwethembeka, kanye nemodi yomjovo eguquguqukayo.Isivinini somjovo, umthamo womjovo, kanye nesikhathi sokulibaziseka kokuskenina singasethwa ngokuya ngezidingo zokuhlolwa.
3.2 Izinyathelo zokuqapha zobuhlengikazi ngokusebenzisa umjovo onomfutho ophezulu
3.2.1 Ubuhlengikazi Bengqondo: Ngaphambi kokuhlolwa, qala ngokungenisa inqubo yokuhlolwa kanye nezimo ezingase zibe khona esigulini, ukuze kuncishiswe ukungezwani kwaso, futhi uvumele isiguli sizilungiselele ngokwengqondo nangokomzimba ukubambisana nokuhlolwa.
3.2.2 Ukukhethwa kwemithambo yegazi: Umjovo we-high pressure unomfutho ophezulu kanye nesivinini somjovo osheshayo, ngakho-ke kuyadingeka ukukhetha imithambo ewugqinsi, eqondile enomthamo wegazi owanele kanye nokunwebeka okuhle okungelula ukuvuza.Imithambo emalungeni, izona ze-venous, i-vascular bifurcations, njll. kufanele igwenywe.Imithambo evame ukusetshenziswa umthambo wesandla ongemuva, umthambo wengalo ongaphezulu, kanye nomthambo wendololwane ophakathi.Kubantu asebekhulile, labo abalashwa ngamakhemikhali isikhathi eside kanye nokulimala kabi kwemithambo yegazi, ngokuvamile sikhetha ukujova izidakamizwa ngomthambo wesifazane.
3.2.3 Ukuvimbela ukungezwani komzimba: Njengoba i-MR yokuhlukanisa iphephile kune-CT umehluko we-CT, ukuhlolwa kokungezwani komzimba ngokuvamile ayenziwa, futhi imithi yokuvimbela ayidingeki.Zimbalwa kakhulu iziguli ezinesicanucanu, ukuhlanza, ikhanda elibuhlungu kanye nomkhuhlane endaweni yomjovo.Ngakho-ke, kuyadingeka ukubuza umlando wokungezwani nesiguli kanye nesimo sokubambisana kwesiguli.Umuthi wezimo eziphuthumayo uhlale utholakala, uma kwenzeka.Ngemuva kokuskena okuthuthukisiwe, isiguli ngasinye sishiywa ukuze sibhekwe imizuzu engama-30 ngaphandle kokusabela okubi.
3.2.4 Ukuvinjelwa kwe-air embolism: I-air embolism ingaholela ezinkingeni ezinkulu noma ngisho nokufa kweziguli, okufanele kusingathwe ngokuqapha.Ngakho-ke, ukucophelela komqhubi, ukuqapha kanye nokusebenza okujwayelekile kuyisiqinisekiso esiyisisekelo sokunciphisa i-air embolism kuze kube nokwenzeka okungenani.Lapho umpompa ama-ejenti wokuqhathanisa, ikhanda lomjovo kufanele libe phezulu ukuze amabhamuza akwazi ukunqwabelana ekugcineni kwesirinji ecijile ukuze asuswe kalula, Lapho ujova, ikhanda lomjovo kufanele libe phansi ukuze amabhamuza amancane antante oketshezini futhi abekwe ekugcineni. wesirinji.
3.2.5 Ukwelashwa kokuvuza okuphakathi nendawo: Uma ukuvuza okuphakathi nendawo kungelashwanga kahle, kungase kubangele i-necrosis yendawo kanye neminye imiphumela emibi.Ukuvuza okuncane kungase kungelashwa noma isisombululo se-magnesium sulfate esingu-50% sizosetshenziselwa ukuminyanisa okumanzi kwendawo ngemva kokuba ihlo yenaliti livaliwe.Uma kuvuza kanzima, isitho esisohlangothini oluvuzayo kufanele siphakanyiswe kuqala, bese kuthi u-0.25% weProcaine usetshenziselwe ukuvala iringi yasendaweni, bese kusetshenziswa isisombululo se-magnesium sulfate esingu-50% ekuminyaniseni okumanzi kwendawo.Isiguli sizotshelwa ukuthi singasebenzisi i-compress yasendaweni, futhi singalulama sibe kwesijwayelekile esikhathini esingangesonto.
