Gauge Gradient Matching Ntawm Koob Loj Thiab Lidocaine Concentration

Pain PointsHauv kev kho cov hlab ntsha thaiv cov tshuaj loog, qhov tsis sib haum xeeb koob ntsuas qhov ntau thiab tsawg thiab lidocaine dilution concentrations yog qhov dav thiab tsis pom qhov mob ntawm qhov chaw kho mob. Cov kws tshuaj loog feem ntau tso siab rau kev xaiv koob ib txwm siv ntau dua li cov qauv loj- kev sib xyaw ua ke cov cai, ua rau tsis muaj kev siv tshuaj loog tsis ruaj khov thiab ua rau muaj teeb meem me me. Ntau tus kws kho mob pem hauv ntej tsis lees paub tias 8G-26G puv - qhov loj me ntawm cov hlab ntsha thaiv cov koob muaj qhov sib txawv ntawm lumen ntws, nruj thiab cov ntaub so ntswg nkag mus. Kev siv loj - tho 8G–14G koob nrog qis - concentration 0.5%–0.9% lidocaine ua rau muaj kev tso tshuaj loog ntau dhau, paj hlwb dhau - thaiv thiab ua kom ntev tom qab phais tas. Hauv qhov sib piv, siv ultra-nplua nuj 20G–26G koob nrog siab-concentration 1.5%–2.0% lidocaine ua rau qeeb txhaj tshuaj nrawm, cov tshuaj hauv zos tsub zuj zuj thiab muaj kev pheej hmoo neurotoxicity ntxiv. Tsis tas li ntawd, kev xaiv qhov loj me yam tsis muaj kev sib txuas ntawm 20ml proportional lidocaine dilution txoj kev ua rau kev faib tshuaj tsis sib haum, qis ib qho - lub sij hawm thaiv kev ua tau zoo thiab tsis zoo rov ua haujlwm ntawm kev kho mob, txwv tsis pub tus qauv ntawm cov tshuaj loog hauv cheeb tsam.

Txoj Cai CoreLub hauv paus ntawm cov paj hlwb raug tshuaj loog yog nyob rau hauv qhov kev hloov pauv ntawm koob ntsuas thiab cov tshuaj loog concentration, raws li cov yam ntxwv ntawm lub cev ntawm qhov loj me - qib cov hlab ntsha thaiv cov koob thiab cov kab lus ua tau zoo ntawm lidocaine. Kev kho mob hlab ntsha thaiv koob ua los ntawm kev kho mob stainless hlau txais cov txheej txheem caj dab thiab swaging, ua tiav 8G-26G loj gradient. Cov lej ntsuas loj dua piv rau cov koob me me sab nraud thiab sab hauv txoj kab uas hla, nrog qis qis qis thiab cov ntaub so ntswg raug mob tsawg, thaum cov lej ntsuas me me txhais tau tias cov koob lub cev tuab dua, rigidity dua thiab nrawm dua cov tshuaj loog. Qhov 0.5% - 2.0% lidocaine concentration ntau sib haum mus rau qhov kev hloov pauv ntawm qhov sib txawv ntawm cov koob sib txawv. Lub 20ml ruaj khov- ntim phau ntawv dilution txoj kev ua tiav qhov kev npaj muaj tseeb, thiab sib piv cov koob tshwj xeeb raws li lub hom phiaj concentration kom ntseeg tau tias cov tshuaj diffusion zoo ib yam, cov hlab ntsha ruaj khov thiab tiv thaiv kom tsis txhob muaj cov concentration{11}}txog thiab ntsuas{12}} cuam tshuam txog kev siv tshuaj loog.

Kev faib cov cuab yeejRaws li qhov loj me thiab qhov chaw kho mob sib piv cov yam ntxwv, cov koob paj paj tau muab faib ua peb pawg gradient uas suav nrog tag nrho 8G-26G specifications. Ua ntej, hnyav loj - bore koob (8G-14G) feature qhov siab tshaj plaws lumen txoj kab uas hla thiab cov txheej txheem rigidity, nrog ceev nrooj ndlwg, tshwj xeeb tshaj yog txuam 1.5% -2.0% siab-concentration lidocaine rau sib sib zog nqus hlab ntsha block. Qhov thib ob, nruab nrab universal koob (15G–19G) sib npaug kev ua tau zoo thiab qhov ua tau zoo me me, haum rau 1.0%–1.4% nruab nrab-concentration lidocaine, npog feem ntau niaj hnub peripheral hlab ntsha thaiv qhov xwm txheej. Thib peb, ultra-cov koob tshuaj tiv thaiv me me (20G–26G) muaj cov lumen me me thiab qis qis qis, ua kom zoo rau 0.5%–0.9% qis-concentration diluted lidocaine rau daim tawv nqaij thiab mos cov tshuaj loog. Txhua qhov ntau thiab tsawg pab txhawb kev sib koom ua tiav thiab ua kom tsis muaj menyuam, thaum qhov ntau thiab tsawg yog muaj rau ib tus neeg siv khoom 2D / 3D kos duab rau kev xav tau tshwj xeeb sib txuam.

Cov Txheej Txheem Ua HaujlwmTsim kom muaj qhov loj me me- kev sib koom ua ke cov txheej txheem ua haujlwm ua ke nrog kev siv lidocaine dilution. Rau qhov tob sciatic paj hlwb thiab brachial plexus block uas yuav tsum tau ceev ceev - kev siv tshuaj loog, npaj 1.6%–2.0% lidocaine ntawm 20ml proportional dilution thiab xaiv 8G–14G loj- bore koob los xyuas kom meej sai thiab tag nrho cov tshuaj diffusion. Rau kev niaj hnub ua haujlwm lidocaine nyob rau hauv tus neeg mob thiab sab nraud kev phais, dilute 1.0%–1.4% nruab nrab-concentration lidocaine thiab txais yuav 15G–19G nruab nrab koob kom sib npaug tshuaj loog stability thiab kev nplij siab ntawm tus neeg mob. Rau cov menyuam yaus, lub ntsej muag thiab subcutaneous superficial block, npaj 0.5%–0.9% qis-concentration lidocaine thiab siv 20G–26G ultra- koob zoo los txo qhov kev raug mob thiab cov hlab ntsha hauv zos. Ua ntej ua haujlwm, txheeb xyuas qhov tseeb ntawm rab koob loj thiab lumen patency, thiab kho qhov kev txhaj tshuaj nrawm raws li rab koob ntsuas kom tsis txhob muaj cov tshuaj tsis sib xws.

Tiag -Kev Paub Txog Ntiaj TebNtev -cov ntaub ntawv soj ntsuam cov ntaub ntawv tshawb fawb tshawb xyuas qhov ntsuas qhov loj me- kev sib xyaw ua ke txo cov hlab ntsha thaiv qhov teeb meem los ntawm 38% piv nrog kev xaiv qhov loj me. Cov tsev kho mob uas siv gradient txuam raws tu qauv tshem tawm tag nrho cov kev phiv xws li cov tshuaj hauv zos tsub zuj zuj, ntau dhau thiab tsis tiav thaiv los ntawm qhov loj me tsis sib haum. Loj -ntev cov koob tuab zoo kawg nkaus tso tawm qhov ua tau zoo ntawm siab -concentration lidocaine, txo qis kev siv tshuaj loog thaum pib los ntawm 30% rau cov hlab ntsha sib sib zog nqus. Ultra-cov koob nyias nyias koom tes nrog qis-kev sib xyaw ua ke ntawm cov tshuaj loog kom txo tau qhov mob tom qab phais thiab qhov o tshwm sim hauv cov pab pawg tsis muaj zog. Kev sib xyaw ua ke ntawm cov cai ntsuas qhov loj me thiab phau ntawv dilution thev naus laus zis tau txhim kho qhov tseeb thiab kev nyab xeeb ntawm cov hauv paus chaw kho mob tshuaj loog, nrog rau cov txiaj ntsig zoo tshaj plaws.

Xaus8G–26G puv - qhov loj me ntawm cov hlab ntsha thaiv cov koob muab lub hauv paus rau qhov sib txawv ntawm lidocaine concentration daim ntawv thov. Kev xaiv qhov loj me hloov mus rau lub cev diffusion cov yam ntxwv ntawm qhov sib txawv ntawm cov tshuaj loog, daws qhov mob tseem ceeb ntawm qhov chaw kho mob ntawm cov tshuaj loog tsis ruaj khov los ntawm kev ua haujlwm empirical. Kev sib koom ua ke ntawm cov qauv kev ntsuas qhov loj me thiab kev faib ua kom sib npaug ntawm cov tshuab ua kom tiav cov txheej txheem ntawm cov hlab ntsha thaiv kev ua haujlwm tshwj xeeb, ua kom paub meej kev sib koom tes ntawm cov ntsuas ntsuas thiab kev siv tshuaj, thiab txhim kho tag nrho qhov zoo ntawm cov tshuaj loog hauv cheeb tsam.

Outlook & Cov lus qhiaCov chaw kho mob yuav tsum suav ua qhov loj me me-cov ntaub ntawv sib xyaw ua ke rau cov hlab ntsha thaiv cov tshuaj loog thiab ntxiv dag zog rau cov txheej txheem kev cob qhia rau cov kws kho mob. Cov cuab yeej siv kho mob tuaj yeem ua kom zoo dua qhov ntsuas qhov ntsuas qhov ntsuas qhov tshwj xeeb rau cov xwm txheej tshwj xeeb thiab tso cov koob tshwj xeeb sib xyaw ua ke. Cov tsev kho mob hauv tsev kho mob yuav tsum ua kom tiav tag nrho - gradient qhov loj ntawm cov khoom lag luam teeb tsa kom npog tag nrho cov kev xav tau ntawm dilution concentration. Nyob rau hauv lub neej yav tom ntej, kev paub txog qhov loj me thiab tsis siv neeg concentration txuam thev naus laus zis yuav ntxiv dag zog rau kev kho kom zoo thiab kev txawj ntse ntawm kev kho cov hlab ntsha thaiv cov tshuaj loog.
