Daim ntawv thov ntawm Echogenic koob nyob rau hauv lub regional tshuaj loog thiab paj hlwb Blocks

Txhim kho Precision thiab kev nyab xeeb hauv Brachial Plexus, Lumbar Plexus, thiab Fascial Plane Blocks

Ultrasound-kev coj noj coj ua hauv cheeb tsam tshuaj loog (USGRA) yog lub peev xwm tseem ceeb ntawm kev siv tshuaj loog niaj hnub no, thiab qhov pom ntawm rab koob ncaj qha cuam tshuam nrog kev thaiv kev ua tiav thiab kev nyab xeeb ntawm tus neeg mob. Ib txwm siv cov koob txhaj tshuaj hauv interscalene, supraclavicular, axillary brachial plexus, thiab erector spinae / transversus thoracis dav hlau blocks nquag ploj thaum cov kaum sab xis tshaj 30 degree. Cov neeg ua haujlwm raug yuam kom "rov qab-infer"rab koobtxoj hauj lwm los ntawm kev tshaj tawm - txhaj tshuaj hypoechoic fluid kis, muaj kev pheej hmoo ntawm kev txhaj tshuaj intravascular hauv zos tshuaj loog, txhaj tshuaj intraneural, lossis pneumothorax.

Siv echogenic koob (tshwj xeeb tshaj yog 22G / 21G / 20G, ntev 50–100 mm nrog micro-etching los yog coatings), lub ncej thiab cov lus qhia raws li lub teeb dawb linear hyperechoic teeb liab thoob plaws. Cov kws kho mob tshuaj loog tuaj yeem soj ntsuam lub sijhawm tiag tiag: ① seb qhov kev nkag mus rau hauv qhov kev sib txawv ntawm cov hlab ntsha / pleura; ② qhov deb ntawm qhov taub mus rau lub hom phiaj paj hlwb; ③ bevel orientation kom meej perineural es tsis yog txhaj tshuaj intraneural. Cov kev tshawb fawb tau lees paub tias cov koob echogenic tau txais txiaj ntsig ntau dua qhov taw qhia thiab lub ntsej muag pom ntawm qhov tob tob ntawm 30℃-60℃piv rau cov koob zoo tib yam, nrog cov neeg ua haujlwm zoo dua qhov kev nplij siab thiab cov qhab nia zoo ntawm cov duab -tshwj xeeb rau cov neeg nyob hauv luv luv lawv txoj kev kawm nkhaus.

Clinical xyaum cov ntsiab lus tseem ceeb:

Hauv - txheej txheem dav hlau ua ke nrog echogenic koob muab cov txiaj ntsig zoo- puv - koob pom kev pom tseeb qhov tob; tawm - ntawm - dav hlau tsuas yog qhia cov lus hla hla - seem dot, tab sis tseem ua haujlwm tsis pom kev.

Echogenic block koob feem ntau feature encrypted etched calibration rings nyob rau hauv 20 mm ntawm lub ntsis, tshwm li intermittent kaj me ntsis nyob rau hauv ultrasound los pab qhov tob kwv yees.

Qee lub tuam txhab muab echogenic block koob nrog cov paj hlwb muaj peev xwm (electrostimulating echogenic koob), combining electrophysiological localization nrog ultrasound visualization rau dual navigation -zoo tagnrho rau tob plexus blocks los yog rog neeg mob.

Lus Cim: Cov txheej txheej muaj zog heev tuaj yeem ua rau "lub hnub qub-tail artifacts" obscuring nyob ib sab hypoechoic neural qauv; nce tuaj yeem tsim nyog txo qis lossis etched hom xaiv los txo cov khoom qub.

Nrog rau kev loj hlob ntawm cov cuab yeej siv ultrasound hauv cov tsev kho mob hauv cov tsev kho mob hauv cov tsev kho mob, cov chaw ua haujlwm nrog cov koob echogenic block koob tau dhau los ua tus txheej txheem kev tswj hwm thiab kev qhia kev teeb tsa hauv tshuaj loog, txo qis kev tsis txaus siab ntawm paj hlwb thiab txhim kho cov neeg mob siab.
