Vi vil gerne anerkende Rachel O'Connell og Jessica Lee for deres hjælp med dyreforsøg. Vi vil også gerne anerkende generalmajor General Harold Timboe, MD, MPH, US Army (Ret.), der har været en rådgiver og mentor for dette projekt.

Forsker ved hjælp af dyr, efterforskerne overholdt Animal Welfare Act forordninger og andre føderale vedtægterne om dyr og eksperimenter, der involverer dyr og principperne fastsat i den nuværende version af vejledningen til pleje og brug af forsøgsdyr af de nationale Forskningsråd. Denne undersøgelse protokollen blev godkendt ved University of Michigan institutionelle Animal Care og brug udvalg (IACUC). Forsøgene blev gennemført i overensstemmelse med alle bestemmelser og retningslinjer vedrørende dyrevelfærd...

I denne protokol fremhævet vi en hæmoragisk chok model i svin. Denne model har vist sig at være både pålidelige og reproducerbare16,17,18,19. Modeller ligner denne har været ansat i flere videnskabelige studier undersøger virkningerne af hæmoragisk chok på Dyrefysiologi16,20. Endvidere, denne model er også blevet brugt til at ...

Blødning er fortsat den dominerende årsag til forebyggelige dødsfald i patienter, der gennemgår traumatiske begivenheder, tegner sig for 90% af traume-relaterede dødsfald i den militære indstilling og 40% af post-traumatisk dødsfald blandt civilbefolkningen1, 2. selv om direkte pres kan behandle Komprimerbar blødning, ikke-Komprimerbar torso blødning er fortsat vanskelig at behandle og kan være dødbringende uden lynhurtig hæmostatisk kontrol. Den historiske tilgang af genoplivning torakotomi eller laparotomi med aorta cross-fastspænding har vist sig for at være meget invasive3,4. Dette indgreb kræver også en kompleks udvalg algoritme til at afgøre kandidatur af patienter, der har gennemgået en traumatisk fornærmelser5.
I de seneste år har der været en genopblussen af interesse i en tidligere beskrevne tilgang — genoplivning endovaskulære ballon okklusion af aorta (REBOA)6,7,8. Selvom REBOA har fået tillagt en kortsigtet overlevelse fordele i blødning, udgør en langvarig komplet okklusion af aorta under ballon inflationen alvorlige bekymringer, der omfatter irreversibel ende-orgel iskæmi9,10. I et forsøg på at overvinde denne potentielle sygelighed, er alternative endovaskulære strategier til at styre blødning ved at blive udtænkt. En sådan strategi, der har set en stigende opmærksomhed er en delvis okklusion af aorta11,12. Tanken om delvis aorta ballon okklusion frembyder perfusion af vaskulære senge distalt for webstedet af okklusion, forbedret fysiologisk proksimale aorta kort og en gradvis afterload reduktion efter ballon deflation. Disse ændringer i parametre er ønskede ændringer af de fysiologiske egenskaber af et blødende dyr. Før denne metode oversættelse til mennesker, komplet og delvis aorta ballon okklusion katetre er blevet stærkt testet i svin modeller af hæmoragisk chok11,12,13.
Svin har været anvendt i studier medfører hæmoragisk chok i mange år. De fleste af de nuværende forståelse af Patofysiologi af hæmoragisk chok er afledt af undersøgelser, der har udnyttet dyremodeller, herunder svin. Deres fysiologi og homeostatiske svar i fastsættelsen af patologiske volumen udtynding følgende blødning, navnlig vedrørende blod blodpropper og hjerte-kar-svar, har været veldokumenteret og er ligesom dem i mennesker14. Svin modeller af hæmoragisk chok giver også muligheder for at undersøge behandling strategier for hæmoragisk stød og andre traumatiske skader.
I denne undersøgelse viser vi en klinisk realistisk model af hæmoragisk chok i svin at evaluere endovaskulære behandling strategier, herunder fuldstændig og delvis aorta ballon okklusion. Vi hypotesen om, at en delvis okklusion af aorta resulterer i en bedre fysiologisk og laboratorium profil i forhold til en komplet okklusion af aorta hos svin undergår en kontrolleret fast volumen blødning.
Vi havde til formål at sammenligne de fysiologiske virkninger af delvise og fuldstændige aorta okklusion som en behandling blødende chok i en svin model. Delvis aorta okklusion blev opnået ved hjælp af en selektiv aorta ballon okklusion i traumer (SABOT) kateter (figur 1). SABOT kateteret er en to-ballon system, der tillader intra-luminale blodgennemstrømning, hvilket giver en delvis aorta flow til de vaskulære senge distalt for okklusion. Komplet aorta okklusion blev opnået ved hjælp af en enkelt-ballon aorta okklusion kateter (fxCODA) (figur 1). Behandlingsgrupper blev randomiseret til at gennemgå genoplivning aorta okklusion enten med den fuldstændige eller delvise aorta ballon okklusion katetre (n = 2/gruppe).
De vigtigste trin i modellen omfatter induktion af anæstesi og intubation, vedligeholdelse af anæstesi, instrumentering, 35% TBV blødning (20 min. alt; halvdelen over de første 7 min, og halvdelen over de resterende 13 min), aorta ballon okklusion og fuldblod genoplivning (60 min af okklusion; 20% fuldblod genoplivning i løbet af de sidste 20 min af okklusion), intensivbehandling overvågning (240 min) med hæmodynamiske observation og eutanasi med væv høst. Figur 2 viser modellen anvendes i dette eksperiment.

complete and partial aortic occlusion for the treatment of hemorrhagic shock in swine

Blødning er fortsat den hyppigste årsag til forebygges dødsfald i traumer. Endovaskulære forvaltning af ikke-Komprimerbar torso blødning har været på forkant med traumebehandlingen i de seneste år. Da komplet aorta okklusion udgør alvorlige bekymringer, har begrebet delvis aorta okklusion fået en stigende opmærksomhed. Vi præsenterer her, en stor dyremodel af hæmoragisk chok at undersøge virkningerne af en roman delvis aorta okklusion ballonkateter og sammenligne det med et kateter, der virker på princippet om fuldstændig aorta okklusion. Svin er bedøvede og instrumenteret for at gennemføre kontrollerede fast volumen blødning, og hæmodynamiske og fysiologiske parametre overvåges. Efter blødning, aorta ballon okklusion katetre er indsat og oppustede i supraceliac aorta i 60 min, hvor dyrene modtager fuldblod genoplivning som 20% af total blodvolumen (TBV). Efter ballon deflation, dyrene bliver overvåget i intensivbehandling omgivelser for 4 h, hvorunder de får væske genoplivning og vasopressors efter behov. Delvis aorta ballon okklusion under ballon inflationen påvist forbedret distale gennemsnitlige arteriel pres (MAPs), faldt markører af iskæmi og faldt væske genoplivning og vasopressor brug. Som svin fysiologi og homeostatiske svar efter blødning har været veldokumenteret og er ligesom dem i mennesker, et svin hæmoragisk kan chok model bruges til at teste forskellige behandling strategier. Ud over behandling af blødning, er aorta ballon okklusion katetre blevet populære for deres rolle i hjertestop, hjerte- og vaskulære kirurgi og andre højrisiko elektive kirurgiske procedurer.

Hæmodynamiske og fysiologiske parametre:
KORTET faldt straks efter blødning (tal 3A - 3D). Fasen i inflationen ballon oplevet dyr i gruppen komplette okklusion en højere proksimale kort i forhold til dyr i gruppen delvis okklusion (tal 3A og 3B). Den gennemsnitlige distale kort under ballon inflationen var højere i gruppen delvis okklusion i forhold til gruppen...
