2024 Tus sau: Michael Samuels | [email protected]. Kawg hloov kho: 2023-12-16 01:44
Peb feem ntau dav siv cov txheej txheem rau plawv catheterization koom nrog kev nkag mus los ntawm femoral, radial, lossis brachial cov leeg , nrog kev nkag mus rau lub brachial cov leeg feem ntau tau los ntawm kev txiav tawm mus kom ze thiab lwm tus los ntawm txoj hauv kev percutaneous.
Hauv qhov no, cov hlab ntsha twg siv rau coronary angiography?
Hauv ib plawv catheterization cov txheej txheem, kws kho mob tso lub raj tso rau hauv cov hlab ntshav hauv koj lub puab tais (hlab ntsha femoral) lossis hauv koj lub dab teg ( radial hlab ntsha ). Tom qab ntawd lub catheter yog threaded los ntawm koj cov hlab ntsha mus rau koj lub plawv.
Ib sab saum toj no, lub plawv catheterization loj npaum li cas? Cov kev pheej hmoo cuam tshuam nrog catheterization suav nrog: kev tsis haum tshuaj rau cov khoom sib txawv lossis cov tshuaj siv thaum lub sijhawm txheej txheem. los ntshav, kis kab mob, thiab ua pob rau ntawm raj qhov chaw ntxig. ntshav txhaws, uas yuav ua rau ib tug plawv tawm tsam, mob stroke, lossis lwm yam loj teeb meem.
Tsis tas li ntawd paub, yuav ua li cas lub plawv cath qhia?
Mob plawv yog ua kom paub seb koj puas muaj kab mob ntawm tus kab mob plawv cov leeg, li qub coronary ( plawv ) cov hlab ntsha. Thaum ua cov txheej txheem, lub siab thiab cov ntshav ntws hauv koj plawv tau ntsuas. Coronary angiography (PDF) ua tiav thaum lub sijhawm mob catheterization.
Puas yog koj tsaug zog thaum lub plawv catheterization?
Plawv catheterization feem ntau yog ua nyob rau hauv tsev kho mob thaum koj yog tsaug zog , tab sis sedated. Cov txheej txheem feem ntau ua los ntawm kws kho plawv. Koj yuav tau txais tshuaj los pab koj so los ntawm IV nyob rau hauv koj txhais caj npab, thiab ib qho tshuaj loog hauv zos kom loog ntawm qhov chaw uas lub koob txhaj (hauv puab tais, caj npab, lossis caj dab).

Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha capillaries?
Piav qhia: Cov hlab ntshav nqa ntshav nyob hauv siab los ntawm lub plawv mus rau cov kabmob thiab cov nqaij. Lawv cov phab ntsa feem ntau yog tuab dua li cov leeg. Capillaries yog qhov sib txuas ntawm cov hlab ntsha thiab cov leeg thiab me me heev, Cov ntaub so ntswg qee zaum pom tawm thiab rov nco qab los ntawm cov qog ntshav thiab rov qab los rau cov leeg ntshav
Dab tsi yog qhov txawv ntawm qhov mob hlab ntsha tawg thiab mob hlab ntsha tawg stasis?
Arterial ulcers tsim los ntawm kev puas tsuaj rau cov hlab ntsha vim tsis muaj cov ntshav ntws mus rau cov ntaub so ntswg. Venous ulcers tsim los ntawm kev puas tsuaj rau cov hlab ntsha uas tshwm sim los ntawm cov ntshav tsis txaus rov qab mus rau lub plawv. Tsis zoo li lwm qhov txhab, cov ceg mob no tuaj yeem siv sijhawm ntau lub hlis los kho, yog tias lawv zoo txhua lub sijhawm
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
