Aug 09, 2026
Spinal anesthesia yog ib qho kev siv tshuaj loog uas siv ntau tshaj plaws hauv kev kho mob niaj hnub no, suav nrog kev phais mob hauv plab, pelvic, qis qis thiab perineal phais. Txawm li cas los xij, cov txheej txheem lumbar puncture ib txwm tau ntev tau cuam tshuam los ntawm ntau qhov chaw kho mob uas cuam tshuam rau tus neeg mob kev nyab xeeb thiab rov qab ua haujlwm tom qab. Qhov teeb meem tseem ceeb tshaj plaws yog qhov tshwm sim ntau ntawm kev sib tsoo- muaj feem cuam tshuam, suav nrog cauda equina paj hauv paus raug mob, tom qab- mob taub hau dural, mob meningeal, mob nraub qaum thiab txawm tias mob hlwb hernia hauv siab - cov neeg mob uas muaj kev pheej hmoo siab. Ntau lub tsev kho mob tseem ceeb tseem siv tsis yog - tus qauv puncture koob thiab cov txheej txheem ua haujlwm tsis tu ncua, ua rau muaj kev cuam tshuam qis qis qis, urinary disorders thiab mob tsis tu ncua tom qab phais hauv qee tus neeg mob. Tsis tas li ntawd, qhov tsis sib haum xeeb ntawm rab koob tshwj xeeb thiab qhov tsis tsim nyog ntawm rab koob tsim feem ntau ua rau cov kua cerebrospinal ntau dhau thiab cov ntaub so ntswg puas, ua rau tus neeg mob lub sijhawm mus pw hauv tsev kho mob ntev thiab ua rau muaj kev kho mob hnyav ntxiv. Cov teeb meem siv tau sai sai no yuav tsum tau ua qauv, siab -kev ua tau zoopov tseg spinal anesthesia koobkom optimize tag nrho cov puncture thiab tshuaj loog txheej txheem.
Lub hauv paus ntsiab lus ua haujlwm ntawm cov koob txhaj tshuaj loog uas siv tau yog siv los ntawm kev siv tshuab neuraxial puncture tsawg heev. Ua los ntawm siab -kev kho mob zoo stainless hlau, rab koob lub cev nta du nto thiab cov qauv tsim, uas tuaj yeem nkag mus rau ntawm daim tawv nqaij, cov ntaub so ntswg subcutaneous thiab ligament txheej kom ncav cuag qhov chaw subarachnoid. Tom qab ua tiav kev sib tsoo, cov neeg ua haujlwm kho mob tuaj yeem txhaj tshuaj loog sib npaug mus rau hauv tus txha caj qaum los thaiv cov leeg txha caj qaum, yog li ua tiav cov tshuaj loog hauv cheeb tsam thiab tshem tawm qhov mob phais. Sib txawv ntawm cov koob txhaj tshuaj uas siv tau rov qab siv tau, cov khoom siv pov tseg tag nrho kom tsis txhob hla - kis kab mob los ntawm kev tua kab mob tsis tiav ntawm cov cuab yeej kho mob rov qab. Tus qauv siv lub cev tuab thiab ntev tsim tuaj yeem tswj tau qhov tob thiab lub kaum ntse ntse, txo cov ntaub so ntswg tearing thiab paj hlwb puas tsuaj, thiab txhim kho kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm ntawm tus txha caj qaum.
Cov koob tshuaj loog uas siv tau siv tau yog feem ntau cais raws li koob tip hom, gauge loj thiab koob lub cev ntev, ua tiav cov khoom lag luam kom hloov mus rau ntau qhov chaw kho mob. Nyob rau hauv cov nqe lus ntawm kev tsim koob, muaj ob lub ntsiab lus tseem ceeb: Quincke Point thiab Pencil Point. Lub Quincke Point nrog ntse bevel yog haum rau ceev ceev ntawm cov ntaub so ntswg txheej txheej, thaum Pencil Point nrog blunt rounded tip minimizes dural trauma thiab ho txo qhov tshwm sim ntawm postoperative mob taub hau. Hais txog koob ntsuas, cov khoom lag luam npog 16G txog 27G tag nrho- qhov tshwj xeeb loj, nrog cov qauv ntsuas loj (16G-19G) rau cov neeg mob tuab adipose thiab cov kab mob tsis yooj yim, thiab cov koob ntsuas me me (22G-27G) rau kev phais me me thiab cov neeg mob rhiab heev. Tus qauv koob ntev yog 90mm, thiab qhov ntev customized tuaj yeem tsim tau raws li kev xav tau kev phais tshwj xeeb, tag nrho npog cov neeg laus thiab cov menyuam yaus kev soj ntsuam daim ntawv thov scenarios. Txhua qhov tshwj xeeb sib raug rau cov xim xim ruaj khov, ua kom yooj yim rau kev txheeb xyuas sai thiab siv cov qauv siv los ntawm cov neeg ua haujlwm kho mob.
Cov txheej txheem kev ua haujlwm tau zoo yog qhov tseem ceeb los txo cov teeb meem kev sib tsoo thiab txhim kho kev siv tshuaj loog. Ua ntej ua haujlwm, cov neeg ua haujlwm kho mob yuav tsum xaiv cov koob txhaj tshuaj raws li tus neeg mob lub hnub nyoog, qhov hnyav, lub cev thiab hom kev phais, thiab nruj me ntsis xyuas cov khoom ntim kev ncaj ncees thiab lub sijhawm kom tsis muaj menyuam. Thaum lub sijhawm ua haujlwm, tus neeg mob tau muab tso rau hauv tus qauv lateral decubitus los yog zaum puncture txoj hauj lwm kom nthuav tawm lub lumbar intervertebral qhov chaw. Lub koob txhaj tshuaj yog ntxig maj mam nyob rau hauv nruab nrab ntawm tib neeg lub cev kom tsis txhob muaj qhov sib txawv ntawm qhov nruab nrab, tiv thaiv kev raug mob rau cauda equina paj hauv paus. Tom qab paub meej tias muaj kev vam meej subarachnoid puncture los ntawm cerebrospinal kua outflow, tshuaj loog yog txhaj ntawm ib tug uniform ceev. Tom qab ua haujlwm, rab koob yog rub tawm maj mam, thiab qhov chaw puncture yog compressed thiab bandaged kom zoo. Cov neeg mob tau qhia kom tuav lub supine txoj hauj lwm rau lub sij hawm teem tseg kom txo tau cov kua cerebrospinal to thiab tsis txhob intracranial siab fluctuation.
Ntau xyoo ntawm kev siv tshuaj kho mob tau txheeb xyuas qhov tseeb tias daim ntawv thov kev siv cov koob txhaj tshuaj txha caj qaum tuaj yeem txo qhov tshwm sim ntawm ntau yam teeb meem. Cov ntaub ntawv kho mob qhia tau hais tias kev siv Pencil Point koob tuaj yeem txo qhov tshwm sim tom qab- mob taub hau dural puncture ntau dua 80% piv nrog cov tsoos ntse - cov koob taub hau, thiab cov txheej txheem midline puncture yuav luag tsis tuaj yeem rov qab los ntawm cauda equina paj hlwb raug mob. Qhov tsim nyog xaiv ntawm koob ntsuas yog qhov tseem ceeb rau kev nyab xeeb ntawm kev phais: cov koob zoo tshaj 25G yog qhov zoo dua rau kev phais mob sab nraud tsawg kawg nkaus kom txo tau cov ntaub so ntswg puas tsuaj, thaum cov koob tuab hauv qab 20G yog qhov tsim nyog rau ntev - lub sij hawm phais txoj kev phais kom ntseeg tau tias kev txhaj tshuaj zoo. Tsis tas li ntawd, kev ua haujlwm nruj aseptic thoob plaws tag nrho cov txheej txheem yog tus yuam sij rau kev tiv thaiv kab mob meningeal thiab txha caj qaum osteomyelitis, thiab kev soj ntsuam ua ntej intracranial siab yuav tsum tau ua rau siab - cov neeg mob pheej hmoo kom tsis txhob muaj mob qog nqaij hlav hauv hlwb.
Hauv cov ntsiab lus, cov koob tshuaj loog uas siv tau pov tseg tau daws qhov mob tseem ceeb ntawm kev phais mob lumbar puncture xws li cov teeb meem siab, kev nyab xeeb tsis zoo thiab cov qauv qis los ntawm cov khoom siv tau zoo, cov qauv tsim thiab cov yam ntxwv tsis zoo. Raws li cov cuab yeej siv kho mob tseem ceeb rau kev siv tshuaj loog, nws cov txheej txheem kev faib tawm thiab cov qauv kev ua haujlwm zoo heev txhim kho tag nrho qib ntawm kev kho mob neuraxial tshuaj loog. Nrog rau kev txhim kho txuas ntxiv ntawm cov qauv kev kho mob, kev ua kom tsawg tsawg, kev nyab xeeb thiab tus qauv siv tshuaj loog tau dhau los ua qhov kev txhim kho tseem ceeb.
Nrhiav rau pem hauv ntej rau kev txhim kho kev lag luam, cov chaw tsim khoom siv kho mob yuav tsum ua kom zoo dua cov khoom lag luam, txhim kho cov khoom tsim kho tus kheej ntau dua rau cov pab pawg tshwj xeeb xws li cov neeg mob rog thiab cov neeg laus. Cov tsev kho mob yuav tsum ntxiv dag zog rau cov txheej txheem kev cob qhia ntawm cov neeg ua haujlwm kho mob, koom ua ke cov qauv xaiv cov qauv thiab kev ua haujlwm tshwj xeeb. Kev lag luam yuav tsum tau txhawb nqa qhov nrov tshaj plaws ntawm -kev ua tau zoo Pencil Point koob, ua kom tshem tawm cov cuab yeej siv rov qab rov qab, thiab txuas ntxiv txhim kho kev nyab xeeb, kev nplij siab thiab kev ua qauv ntawm kev kho mob txha caj qaum.
