Kuyini ukushaqeka hypovolemic?

Shock ibizwa ngokuthi isimo esibucayi, lapho ngokucijile encishisiwe isitho perfusion, okungukuthi zonke, ikakhulukazi ezithweni ezibalulekile kukhona in a state of ukuntuleka komoya-mpilo.

Esinye sezizathu simo ubhekwa: a lesion esibuhlungu, ukusha, ukulahlekelwa igazi, isifo buthakathaka abukhali umsebenzi senhliziyo esilimele, hit allergen emzimbeni, okuyinto phambilini batiswe.

izinhlobo ukushaqeka

Kuye izizathu, okwaphumela asathuthuka lokhu isimo, ungakhetha izinhlobo eziningana:

1. ukushaqeka hypovolemic;

2. kuhlasimulise noma ubuhlungu;

3. Burn;

4. anaphylactic;

5. ezithathelwanayo kanye anobuthi;

6. cardiogenic;

7. Isango.

ukushaqeka hypovolemic

Lolu hlobo lwe-isimo esibucayi eba avame. Ngenxa yalesi sizathu, kuyafaneleka ubuka incazelo ngokuningiliziwe. ukushaqeka Hypovolemic kubangelwa i Ukushoda okukhulu kwabantu afundwa umthamo wegazi. Ngenxa encishisiwe ukubuya emithambo yegazi enhliziyweni futhi kwenzeka ukwehla zamabanga okukhipha inhliziyo.

Izimbangela ngqo lolu hlobo isimo esiphuthumayo kukhona ukopha (zangaphakathi nezangaphandle); ukulahlekelwa uketshezi izifo ezithathelwanayo. Ukwehlisa umthamo wegazi futhi kungase kubangelwe ekuqongeleleni uketshezi ngaphakathi komgodi ongaphakathi kwamathumbu ngesikhathi peritonitis, kuhlasimulise umonakalo izicubu zomzimba ezithambile.

ukushaqeka Hypovolemic e izifo ezithathelwanayo eba ngenxa degitratatsionnym syndrome, ngokuvamile izifo emathunjini, okungukuthi, ukudla okunobuthi, salmonellosis, ikholera nokunye. Nokho, lokhu akusho ngaso sonke isikhathi kwenzeke. Uma impatho ukutheleleka emathunjini waqala ngendlela esifike ngesikhathi, isimo esibucayi ezinjalo ngeke ukuthuthukisa.

Ukuze uqonde kangcono ukuthi yini ukushaqeka hypovolemic, kubalulekile ukuba sicabangele pathogenesis sokuthuthuka. Ukuthuthukiswa Its zingahlukaniswa izigaba ezintathu:

1. yokuntuleka afundwa umthamo wegazi;

2. ukusebenza kohlelo nozwela-adrenal;

3. ngqo ukwethusa.

In the isinyathelo sokuqala umzimba womuntu azizwa umthamo woketshezi ukushoda egazini esiboniswa ngincipha ukugeleza emithambo yegazi ukuze inhliziyo, encishisiwe ingcindezi emaphakathi. Ngenxa yalokho lezi zinqubo kuyehla okukhipha inhliziyo. Phakathi kwehora lokuqala e-capillary ivame uketshezi interstitial, futhi ngaleyo ndlela kunciphisa ivolumu wemboni intercellular.

Ngo esigabeni sesibili, uhlelo baroreceptor ukushukuma reflex, okuyinto iqhubezela ohlelweni onozwela-adrenal. Ngenxa yalokho, it kwandisa uketshezi we catecholamines: noradrenaline enyuka ngokuphindwe kayishumi, i-adrenalin - emakhulwini.

Ngesikhathi esifanayo kukhona ukuncipha nozwela ithoni imithambo yenhliziyo futhi arteriole, oluhilela ukwanda ikhono ukunciphisa infarction futhi inhliziyo palpitations. Bese kukhona yinye kwegazi. Esigabeni sesithathu, oqala ngokungabi bikho kokwelashwa, okuholela hypovolemia nokunwetshiwe eba ukwehla ziphikelele perfusion.

ukushaqeka Hypovolemic kubonakala emtholampilo njalo encane ishayela; ongaphakeme -systolic blood pressure; wehlise enkabeni ingcindezi emithambo yegazi; Cold, zinomswakama cyanotic okhanyayo ngisho isondo nangemabula; okwehlisa ka igazi ligeleze embhedeni nail; oliguria.

Uma uneminye izimpawu ukushaqeka hypovolemic kufanele axhumane ngokushesha ne sikhungo yezokwelapha ukuze uthole usizo. Ungacabangi ukuthi isimo esinjalo ingakwazi iboshiwe. Ukuze ugcine umuntu, kungcono ushayele nabasebenza ambulense, namanje at the stage of zokuthutha uzoqala ukunikeza usizo lokuqala. Kuleli zinga, ngisho ukubambezeleka kancane lalingabiza umuntu ekuphileni kwabo.
