Nov 21, 2022
Nerve block yog ib txoj kev siv tshuaj loog hauv tsev kho mob thiab tseem siv tau los kho qee yam kab mob.
Nws feem ntau suav nrog cov paj hlwb (ulnar paj hlwb, femoral paj, thiab lwm yam), paj hlwb plexus (brachial plexus, cervical plexus, thiab lwm yam) thiab ganglion (stellate ganglion) block.
Cov yam ntxwv zoo ib yam yog: txhaj tshuaj loog hauv zos nyob ib ncig ntawm cov hlab ntsha (plexus), ib ntus thaiv cov hlab ntsha impulses, tsis hnov qab ib ntus thiab / lossis lub cev muaj zog hauv thaj chaw innervated, analgesia thiab nqaij so rau kev phais, lossis kev kho mob.
Vim qhov sib txawv ntawm qhov chaw anatomical thiab kev faib tawm, cov teeb meem thiab kev tsis zoo tshwm sim los ntawm cov hlab ntsha (plexus) thaiv nyob rau hauv ntau qhov chaw kuj txawv.
Vim tias qhov chaw thiab qhov chaw ntawm cov hlab ntsha (plexus) tsis yooj yim rau kev txheeb xyuas qhov tseeb ntawm lub cev, qhov puncture feem ntau yog raws li kev soj ntsuam, yog li qhov kev vam meej ntawm cov tshuaj loog uas muaj kev paub tsawg dua yog qhov tsawg, thiab qhov tshwm sim ntawm cov teeb meem tseem ceeb heev. , tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm rov qab nrhiav kev sib txawv thiab rov puncture. Nws feem ntau yuav ua rau muaj kev puas tsuaj rau cov ntaub so ntswg ib puag ncig, xws li los ntshav los ntawm cov hlab ntsha puas, hematoma thiab compression ntawm ib puag ncig cov ntaub so ntswg thiab lub cev, los yog punctured pleura uas ua rau pneumothorax, ntsws puas, thiab tshuaj loog hauv zos lom thiab lwm yam teeb meem loj.
Txhawm rau txhim kho txoj kev vam meej ntawm cov hlab ntsha (plexus) thaiv thiab txo qhov tshwm sim ntawm cov teeb meem, ntau xyoo ntawm kev tshawb fawb soj ntsuam tau ua tiav, xws li kev xaiv cov ntsiab lus puncture raws li qhov chaw phais thaum lub sij hawm brachial plexus block, siab thiab Txoj hauv kev qis ntawm cov leeg nqaij sulcus, subclavian mus kom ze, cov txheej txheem subcoracoid, txheej txheem paracoracoid, thiab coracoid brachial qhov chaw mus kom ze. Qhov chaw ntawm qhov chaw ntawm thawj tav, ntau qhov kev txhaj tshuaj ntawm ib qho kev txhaj tshuaj, thiab txuas ntxiv lossis ntau qhov thaiv kev sib xyaw ua ke, thiab lwm yam. Cervical plexus block tau ua los ntawm kev hloov kho C4 transversal one-point method, siab lub taub hau puncture ntawm intermuscular sulcus thiab lwm yam. Nyob rau hauv xyoo tas los no, qhov chaw ntawm lub paj hlwb (plexus) nrog neurostimulator tau siv hauv tsev kho mob thiab qee qhov kev paub tau txais. Cov txheej txheem no yuav pab tau kom txhim kho qhov ua tau zoo ntawm kev sib tsoo, tab sis cov teeb meem tshuaj loog tseem tshwm sim ib ntus. Qhov ua rau muaj teeb meem xws li kev ua haujlwm tsis zoo lossis kev ua haujlwm tsis raug, kev xaiv tsis raug ntawm kev sib tsoo thiab qhov txawv txav ntawm tus neeg mob lub cev.
