Air embolism - isifo esiyingozi

embolism esithi ukuqonda ukwakheka iyiphi ezihambayo amahlule ezinkulu noma yokulimala imithambo yegazi. Air embolism kuwumphumela kwema- i bubble air emgudwini wegazi. Lokhu bubble idluliswa eduze Umthambo, bese kuqhutshekwa ngokusebenzisa ezincane imithambo yegazi ukuthi ekugcineni unciphise ukuba ama-capillary. Ngesinye isikhathi esededelwe, emoyeni embolism amabhlogo umfula, kanjalo kokuma ukugeleza kwegazi ezindaweni ezihlukahlukene zomzimba. into enjalo ngokuvamile ebonwe okusheshayo indoda izigelekeqe ngemva ezijulile ulwandle diving phezu kwamanzi. Ngakho umzimba akakwazi ukubhekana ukuhoxiswa nitrogen okweqile kusukela igazi, futhi yakha air Bubbles kwezicubu futhi imithambo yegazi. Lezi Bubbles nitrogen kubangele decompression ukugula (decompression). Kuleli zinga, singenzeka ebulalayo, ikakhulukazi uma igesi bubble esikhulu singena imisipha yenhliziyo. Lapho lokhu kuvimbela ukugeleza igazi i-ventricle yangakwesokudla emaphashini. ngezinye izikhathi Arterial emoyeni embolism kwenzeka ngenxa dlula cardiopulmonary nezinye izinqubo kuhlinzwa e imithambo yegazi. Ukuvaleleka emoyeni Umthambo, kungase kubangele ukufa uma ukuvaleka nemithambo yegazi yenhliziyo futhi palsy.

Ngaphezu kwalokho embolism okwenzeka imithambo singenzeka futhi emithambo yegazi emoyeni embolism, okuyinto is phetho ukwethulwa air Bubbles ngemithambo yegazi. Iphinde uyingozi ekuphileni lesiguli, ngoba kungaba ukuvimba yamaphaphu ukugeleza kwegazi.

Izimpawu ze-air embolism ngesikhathi decompression yilezi:

- ubuhlungu emalungeni;

- ubuthaka nemilenze;

- isiyezi;

- ukukhathala ezinzima;

- ndikindiki futhi ukuluma emikhawulweni;

- ukuqubuka kwesikhumba futhi nokulahlekelwa ukwazi;

- ezimweni ezinzima - a ukukhubazeka okuphelele.

Ezimweni eziningi, izindawo elivela kuzo enkulu emoyeni emboli e imithambo cerebral uphela ngokushesha nokulahlekelwa ukwazi futhi ngokuvamile kubangela nokuquleka. Kuleli zinga, kungenzeka ube nesifo sohlangothi. Air embolism enhliziyweni noma yenhliziyo imithambo ukuthi ukondla inhliziyo kungabangela isifo senhliziyo. nezimbangela zayo futhi emboli omkhulu ezifundeni ezingu imithambo palsy.

Limelela ibe usongo olukhulu empilweni kanye embolism yamaphaphu - embolism ka imithambo yegazi elise emaphashini. Kubangela ezinzima esifubeni ubuhlungu kanye nezinkinga zokuphefumula. embolism yamaphaphu kungadalwa ukuvaleka okungazelelwe we yamaphaphu Umthambo embolism. Lesi simo kuyinto inkinga ezivamile futhi sina in iziguli umgudu wokuphefumula.

Embolus kungaba thrombus (igazi ihlule), kodwa futhi ngezinye izikhathi ingaba umthombo:

- amafutha (uma waphuka ahlukene isisindo umnkantsha amafutha ngezinye izikhathi lingena ngokusebenzisa izitsha kabana ukugeleza ukusakaza futhi clog imithambo yegazi endaweni indlela abaphila ezihlukahlukene kwezicubu, ikakhulukazi ubuchopho kanye ukukhanya; izidakamizwa embolism kwenzeka uma injected izixazululo oily intramuscularly noma phansi kwesikhumba at Ukungena okungahleliwe inalithi isitsha igazi);

- amniotic (fluid) uketshezi lapho ukhulelwe;

- nomzimba angaphandle (e izilonda);

- umnkantsha;

- izimuncagazi, ama-bacterium, izinsalela isimila esinomdlavuza.

Okungenzeka yokufa embolism yamaphaphu incike embolus, ubukhulu bayo kanye nenani ivinjiwe imithambo yamaphaphu. Isici esibalulekile iyinkinga yempilo lesiguli jikelele. Ngezinye izifo ezihlukahlukene sina kwamaphaphu futhi inhliziyo embolism iyona ayingozi kakhulu. Uma embolism kwenzeka main Umthambo yamaphaphu esiqwini, ukufa, zingaba khona ngaphakathi 1 ihora.

Balinganiselwa ku-50% azo zonke iziguli ezine-embolism yamaphaphu abangamkhonzi usizo ngesikhathi esifanele enikeziwe, kukhona kabusha embolism. Ngo-50% amacala, umuntu abuyele kulo mkhuba. enjalo okusongelayo ukuphila kwesiguli. Indlela ephumelela kunazo ukuthi kunciphisa amathuba ngiwela ogibeni lwezidakamizwa, ukusetshenziswa anticoagulants (izidakamizwa ukuthi ukunciphisa igazi ekunqandeni).

inkinga Ukuphuthuma embolism kubangelwa ngobucayi izifo okusezingeni eliphezulu iphesenti lokufa futhi nobunzima zokuxilonga yezinkinga enjalo.

Ukwelashwa kweziguli embolism wenziwa labagula. Uma usola ukuthi lesi sifo kudingeka esibhedlela ngokushesha isiguli.
