hypovolemic mantha

Mtundu wa boma ovuta akufotokozera zambiri. Pachifukwa chimenechi, tiyenera kuyang'ana pa kulongosola mwatsatanetsatane. mantha Hypovolemic amayamba ndi kusowa wokonda kufalitsidwa magazi buku. Chifukwa cha kuchepa venous kubwerera ku mtima ndipo amapezeka kuchepa sekondale linanena bungwe mtima.

Zimayambitsa mwachindunji mtundu wa boma mwamsanga ndi kukha mwazi (onse kunja ndi mkati); imfa ya madzimadzi ku matenda opatsirana. Kuchepetsa voliyumu ya magazi komanso zotsatira zake kudzikundikira madzimadzi mu zonse m'mimba pa peritonitis, zoopsa minofu zofewa kuwonongeka.

Hypovolemic mantha matenda opatsirana akufotokozera chifukwa syndrome degitratatsionnym, nthawi zambiri matenda matumbo, ndicho poyizoni chakudya, salmonellosis, kolera, ndi zina zotero. Komabe, sikuti zonse zichitike. Ngati mankhwala a matenda matumbo anayamba m'nthawi yake, monga kudwala mwakayakaya bbwino.

Kumvetsetsa zimene hypovolemic mantha, m'pofunika kuganizira pathogenesis wa chitukuko. chitukuko akhoza kugawidwa mu magawo atatu:

1. Kusowa kwa kufalitsidwa magazi buku;

2. kutsegula kwa dongosolo wachifundo-adrenal;

3. mwachindunji kudabwitsa.

Mu ndime yoyamba thupi la munthu amamva madzimadzi buku kuchepa mu m'magazi kuti kukuonetsedwa kucheperachepera otaya venous mtima, yafupika kuthamanga kwambiri. Chifukwa cha njira izi yafupika linanena bungwe mtima. Pa ola loyambirira mu capillaries amamuchititsa madzimadzi interstitial, chotero amachepetsa buku la gawo intercellular.

Mu gawo lachiwiri, baroreceptor reflex kukondoweza, amene chimathandiza chifundo-adrenal dongosolo. Chifukwa, izo kumawonjezera katulutsidwe wa makatekolamaini: noradrenaline kuchuluka tenfold, zikuwonjezereka masiku ano - mu mazana.

Pa nthawi yomweyo pali kuchepetsa mitsempha wachifundo kamvekedwe, mtima ndi arterioles, amene kumatanthauza kuwonjezeka mu mphamvu kuchepetsa infarction ndi mtima palpitations. Ndiyeno pali centralization kufalitsidwa. Mu gawo lachitatu, limene limayamba pakalibe chithandizo, chifukwa mu hypovolemia yaitali akufotokozera kulimbikira kuchepa perfusion.

mantha Hypovolemic akuwonekera kukomoka pafupipafupi yaing'ono zimachitika; otsika systolic magazi; ndichepe mu kuthamanga chapakati venous; Cold, chinyezi, wotumbululuka cyanotic ngakhale nsangalabwi gudumu; liwiro la magazi ndi msomali kama; oliguria.

Ngati muli zizindikiro zilizonse kakasi hypovolemic ayenera yomweyo kulankhula ndi malo zamankhwala. Musaganize kuti boma akhoza mosadalira padokopo. Kuti apulumutse munthu, ndi bwino kuitana anthu oyendetsa za ambulansi, amene akadali pa siteji ya mayendedwe adzayamba kupereka thandizo. Mmenemonso, ngakhale akuchedwa pang'ono zingawatayitse munthu moyo wawo.
