Bone Marrow Blood Puncture Koob
Dec 08, 2022
Subcutaneous thiab subperiosteal kua. Feem ntau ua rau yog subcutaneous thiab subperiosteal kua extravasation ntawm qhov chaw puncture, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm pressurized infusion los yog daim ntawv thov ntev. Lub exosmosis ntawm irritating kua uas muaj sodium bicarbonate tej zaum yuav ua rau lub zos o los yog kis kab mob nyob rau hauv me me, los yog ua rau cov ntaub so ntswg necrosis nyob rau hauv mob hnyav. Lub sijhawm no, IO yuav tsum raug txiav tawm thiab kev siv lub zog hauv zos tuaj yeem ua tau. Qhov tshwm sim ntawm lub zos cellulitis thiab subcutaneous abscess tshwm sim los ntawm infusion extravasation thiab infiltration yog 0.7 feem pua . Cov kua dej extravasation kuj tuaj yeem tshwm sim hauv cov pob txha raug mob nrog cortical fractures, thiab cov pob txha cuam tshuam yuav tsum tsis txhob punctured.
Cov pob txha tawg. Tsawg heev.
Lwm yam. Cov no suav nrog cov ntawv ceeb toom ntawm kev nkag mus rau hauv lub cev nrog mediastinitis, subperiosteal infusion, pob txha pob txha raug mob, intraarticular misplacement, kab mob hauv zos, pin loosening, pin breakage, me nyuam mos loj hlob phaj raug mob, sepsis, thiab muaj peev xwm muaj roj embolism.
Raws li histological thiab radiological hloov ntawm cov pob txha pob txha tom qab infusion, hypertonic kua yuav ua rau cov pob txha pob txha necrosis thiab fibrin deposition, thiab nce periosteum cov tshuaj tiv thaiv. Kev soj ntsuam histological ntawm cov tsiaj sim nrog qhov tsis zoo tshwm sim tau pom tias sternal trabeculae thiab cov pob txha pob txha muaj roj tsis raug puas tsuaj, tab sis cov hlwb hematopoietic tau ploj mus lossis poob qis dua 1 ~ 2 hnub tom qab kev txhaj tshuaj, thiab 2 ~ 6 lub lis piam tom qab txhaj tshuaj, cov pob txha kuaj ntawm qhov chaw txhaj tshuaj pom tau tias lub oligocytic cheeb tsam tau hloov los ntawm cov ntaub so ntswg fibrous, thiab cov kev hloov saum toj no tsuas yog pom nyob rau hauv txoj kab uas hla ntawm 0.6 cm ntawm qhov chaw txhaj tshuaj. Tsis muaj kev ua haujlwm lossis cov pov thawj histological ntawm pulmonary embolism, thiab cov teebmeem ntawm lub cev tsis zoo.
