Daim duab ntawm Contraindications thiab ciam teb: Tag Nrho -Kev Tswj Xyuas Txheej Txheem rau Kev Siv Tshuaj Kho Mob Zoo
Q&A Txoj Kev
Tau ntsib tus neeg mob leukemia uas nws cov platelets tsuas yog 20 × 10⁹ / L, tab tom ua cov pob txha pob txha biopsy ib kauj ruam kuaj mob tsim nyog lossis kev twv txiaj txaus ntshai? Thaum tus poj niam cev xeeb tub hauv nws lub peb hlis ntuj thib peb muaj cov cytopenia uas tsis tau piav qhia, cov txiaj ntsig thiab kev pheej hmoo ntawm kev kuaj ntshav biopsy hnyav li cas? Lub hauv paus ntawm kev nyab xeeb pob txha pob txha biopsy tswj yog nyob rau hauv navigating tus me me ciam ciam kab nruab nrab ntawm contraindications thiab hloov kho kev txiav txim.
Keeb Kwm Evolution
Qhov kev nkag siab ntawm cov pob txha pob txha biopsy txaus ntshai tau hloov zuj zus los ntawm qhov tsis zoo rau cov txheej txheem ua kom zoo. Cov txheej txheem thaum ntxov tau muab qhov tseem ceeb rau kev kuaj mob raws li lub hom phiaj tseem ceeb, nrog cov teeb meem feem ntau pom tias yog "tus nqi tsim nyog." Cov ntawv ceeb toom ntawm cov xwm txheej tsis zoo xws li los ntshav thiab kis kab mob tau nce hauv xyoo 1970s, ua rau muaj kev ua txhaum cai ntawm cov kab mob contraindications. Xyoo 1980s thiab 90s tau pom muaj kev tsim cov pov thawj- raws li qhov kev nyab xeeb rau kev ua haujlwm coagulation thiab cov platelet suav. Txij li thaum lub xyoo pua 21st, lub zog "Patient Safety" tau tsav kev tsim cov txheej txheem kev ntsuas kev pheej hmoo ntawm tus kheej rau cov neeg tshwj xeeb (xws li cov poj niam cev xeeb tub, menyuam yaus, cov neeg laus). Niaj hnub no, kev nyab xeeb yog internalized raws li ib feem tseem ceeb ntawm cov txheej txheem biopsy.
Cov ntaub ntawv pov thawj-Raws li Kev Ntsuam Xyuas ntawm Core Contraindications
1. Tsis muaj contraindications: Cov kab liab uas hla tsis tau
Uncorrected Severe Coagulopathy
Laboratory Threshold:International Normalized Ratio (INR) >1.5, lossis Activated Partial Thromboplastin Sijhawm (APTT) tshaj 1.5 npaug ntawm qhov txwv siab tshaj ntawm qhov qub.
Pathophysiology:Tsis muaj cov kab mob hauv lub cev tiv thaiv kom tsis txhob muaj cov kab mob thrombus zoo ntawm cov kab mob sib kis, ua rau muaj kev pheej hmoo los ntshav.
Txoj Cai Tswjfwm:Cov txheej txheem yuav tsum raug ncua. Nrog rau Hematology lossis Transfusion Tshuaj txhawm rau kho qhov tsis xws luag nrog ntshav ntshav, ntshav txhaws, lossis Vitamin K ua ntej rov ntsuas dua.
Active Kab mob ntawm qhov chaw Puncture
Risk:Cov txheej txheem tuaj yeem tsav cov tawv nqaij-colonizing cov kab mob mus rau hauv cov kab mob vascularized medullary heev, uas yuav ua rau tuag taus pyogenic osteomyelitis lossis sepsis.
Kev tswj hwm:Txwv tsis pub kiag li. Ib tug yuav tsum xaiv qhov contralateral sab (yog tias tsis muaj kev cuam tshuam) los yog ncua cov txheej txheem kom txog thaum tus kab mob no tau tswj tau thiab daim tawv nqaij zoo.
2. Cov txheeb ze Contraindications: Qhov hnyav hnyav ntawm qhov txaus ntshai vs
Thrombocytopenia
Kev txiav txim siab Matrix:
|
Platelet suav (× 10⁹ / L) |
Risk Level |
Lub tswv yim ua haujlwm |
|---|---|---|
|
>50 |
Tsawg |
Kev ua haujlwm niaj hnub; post-op compression rau 10 mins. |
|
20–50 |
Nruab nrab |
Ua kom ceev faj. Xav txog prophylactic platelet transfusion ua ntej-op; siv ib rab koob zoo (piv txwv li, 15G); ncua kev tshaj tawm -op compression rau 20–30 mins. |
|
<20 |
Siab |
Feem ntau zam. Yog tias kev kuaj mob sai sai (piv txwv li, xav tias mob ntshav qab zib mellitus), ua tam sim ntawd tom qab kev tso ntshav platelet los ntawm tus kws kho mob uas muaj kev paub dhau los. |
Lub cev xeeb tub lig (Tshwj xeeb peb lub hlis twg)
Risk:Feem ntau tsis los ntshav, tab sis qhov kev pheej hmoo ntawm cov txheej txheem tsis xis nyob yuav ua rau lub tsev me nyuam contractions. Txoj hauj lwm yooj yim ua rau muaj kev pheej hmoo loj thiab tsis xis nyob rau leej niam.
Tswv yim:Nyiam qhov Anterior Superior Iliac Spine (ASIS), tso cai rau tus neeg mob pw hauv ib sab lossis ib nrab- txoj haujlwm tsis tu ncua. Yuav tsum muaj kev txiav txim siab sib koom ua ke- ua los ntawm pab pawg neeg ntau yam (Hematology, Obstetrics) thiab npaj rau kev cuam tshuam xwm txheej ceev.
Tag Nrho -Txoj Kev Tswj rau Kev Ua Haujlwm Zoo
Ua ntej -operative "Safety Checklist"
Qhia Kev Pom Zoo:Kev piav qhia ntxaws txog kev pheej hmoo (los ntshav, kis kab mob, mob, perforation) thiab tau txais kev tso cai sau ntawv.
Lab tshuaj xyuas: Yuav tsum tshuaj xyuas tib -hnub CBC thiab coagulation profiles.
Kev lees paub ntawm qhov chaw:Palpate lub Posterior Superior Iliac Spine (PSIS); siv ultrasound rau localization nyob rau hauv cov neeg mob rog rog, tsis txhob phais nti los yog muaj kab mob.
Intra{0}}kev ua haujlwm "Risk Mitigation Techniques"
Kev tswj ntshav ntshav:Tsim nyog periosteal infiltration anesthesia (nrog rau cov tshuaj diluted epinephrine); siv cov ntse, hom- koob tshiab los txo cov ntaub so ntswg.
Pain Management: "Kev txhaj tshuaj qeeb qeeb, Kev nkag mus sai"-Kev txhaj tshuaj loog qeeb qeeb, kev nkag mus sai ntawm lub cortical, thiab cov qauv tau txais sai.
Tiv thaiv "Los ntawm-thiab-Los ntawm":Teeb qhov tob limiters; siv ultrasound los saib xyuas qhov tob tob hauv lub sijhawm tiag -, tshwj xeeb tshaj yog rau cov neeg mob nyias.
Tshaj tawm -operative "Strict Monitocol Protocol"
Compression:Siv lub zog ruaj khov rau ntawm qhov chaw tsawg kawg 15 feeb tom qab siv cov hnav khaub ncaws, saib xyuas kom muaj zog oozing.
Immobilization:Qhia tus neeg mob so hauv txaj rau 2-4 teev; zam qhov hnyav- bearing ntawm sab punctured rau 24 teev.
Kev kawm:Muab cov lus qhia tso tawm kom meej meej txheeb xyuas cov cim kev phom sij (ua npaws, mob hnyav, tsis muaj zog los ntshav) thiab kev tswj hwm lawv.
Ua raws li-: Xov tooj ua raws- nce ntawm 24–48 teev kom paub meej tias tsis muaj kev los ntshav qeeb lossis kis kab mob.
Standardized teb rau cov teeb meem
Local Hematoma:Feem ntau. Me hematomas daws spontaneously; Kev nthuav dav sai sai yuav tsum tau kuaj xyuas ultrasound thiab tejzaum nws tso dej los yog kev phais.
Kab mob:Tsis tshua muaj tab sis hnyav. Yuav tsum muaj kab lis kev cai tam sim ntawd ntawm kev tso tawm thiab empiric broad -spectrum tshuaj tua kab mob.
Neurovascular Injury:Tsis tshua muaj tab sis muaj kev puas tsuaj loj. Ua kom pom tseeb lub hom phiaj nruj anatomical thiab zam dhau - nkag mus rau sab hauv thiab nqes.
Xaus
Kev tswj xyuas kev nyab xeeb ntawm cov pob txha pob txha biopsy yog ib qho txuj ci- coj los ntawm cov pov thawj tshawb fawb thiab kev paub txog kev kho mob - ntawm kev txheeb xyuas, ntsuas, sib txuas lus, thiab tswj kev pheej hmoo. Nws ua kom ntseeg tau tias rab koob, uas yog tus yuam sij rau kev kuaj mob, ua haujlwm tshaj plaws raws li kev tiv thaiv kev nyab xeeb rau tus neeg mob.
