Raws li tus neeg muag khoom ntawmabsorbable hemostatic hais, Kuv nquag nug txog qhov sib txawv ntawm peb cov khoom thiab lwm yam hemostatic agents ntawm lub khw. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov kws kho mob, cov neeg teb thawj zaug, thiab cov tib neeg npaj rau xwm txheej ceev. Cia kuv rhuav nws rau koj raws li cov ntaub ntawv pov thawj kho mob thiab kev ua tau zoo.
Dab tsi yog Hemostatic Agents?
Hemostatic agents yog cov khoom siv los txo cov ntshav. Lawv raug siv rau hauv ntau qhov chaw - los ntawm cov txheej txheem phais mus rau kev sib ntaus sib tua tshuaj thiab kev pab thawj zaug hauv tsev. Hemostatic agents tuaj yeem muab faib ua peb pawg:
Tus neeg sawv cev- Siv ncaj qha rau qhov chaw los ntshav
Cov neeg ua haujlwm zoo- Cov tshuaj noj hauv qhov ncauj lossis txhaj tshuaj los cuam tshuam rau lub cev lub cev
Mechanical agents- Cov khoom siv zoo li tourniquets uas lub cev ua rau cov ntshav ntws
Hnub no, peb yuav tsom mus rauabsorbable hemostatic hais, ib hom tshuaj pleev xim hemostatic uas muaj qhov tshwj xeeb zoo.
Dab tsi yog Absorbable Hemostatic Particles?
Absorbable hemostatic haisyog cov ntaub ntawv zoo granulated tsim los rau kev siv ncaj qha rau qhov chaw los ntshav. Lawv cov yam ntxwv tseem ceeb yog tias lawv maj mam nqus los ntawm lub cev dhau lub sijhawm - feem ntau nyob rau hnub rau lub lis piam - tshem tawm qhov xav tau kev phais tshem tawm. Cov cuab yeej no ua rau lawv muaj txiaj ntsig tshwj xeeb hauv kev phais mob thiab kev kub ntxhov.
Rau qhov kev xaiv txhim khu kev qha thaum muaj xwm txheej ceev, xav txog peb Diatomite Hemostatic Granules rau Kev Kub Ntxhov.
Yuav Ua Li Cas Absorbable Hemostatic Particles Ua Haujlwm
Lub mechanism ntawmabsorbable hemostatic haisyog zoo -cov ntaub ntawv. Thaum cov khoom no nkag mus rau hauv cov ntshav, lawv:
Ua kom pom tseeb ntawm cov ntshav txhaws- Cov khoom muab ib thaj chaw loj heev uas ua rau lub ntuj tsim los ua kom muaj zog
Tsim ib gel-zoo li matrix- Cov gel no cuam tshuam cov platelets thiab cov qe ntshav liab, txhawb kev tsim cov ntshav sai
Ua kom txoj kev coagulation- Qee cov formulations muaj cov ntaub ntawv xws li diatomite los yog chitosan uas nquag txhim kho cov hlab ntshav
Qhov kev ua ntawm lub cev thiab biochemical ua kom ua tiav hemostasis hauv feeb, txawm tias nyuaj los ntshav.
Sib piv Absorbable Hemostatic Particles nrog rau lwm yam Hemostatic Agents
1. Tsis yog-Absorbable Hemostatic Agents
Tsis yog- cov neeg ua haujlwm nqus tau muaj xws li cov ntaub qhwv ib txwm siv, cov ntaub qhwv paj rwb, thiab qee cov ntaub qhwv uas yuav tsum tau ceev ceev. Thaum ua tau zoo rau cov los ntshav me, lawv yuav tsum tau muab tshem tawm tom qab hemostasis - thiab kev tshem tawm tuaj yeem cuam tshuam cov hlab ntsha tshiab, uas tuaj yeem ua rau rov- los ntshav.
Qhov zoo ntawm absorbable hemostatic hais:Tsis xav tau kev tshem tawm. Cov khoom no tau txais kev nyab xeeb los ntawm lub cev, txo qhov kev pheej hmoo ntawm kev cuam tshuam ntawm cov ntshav txhaws thiab los ntshav los ntshav.
2. Cov kab mob hemostatic
Cov neeg ua haujlwm hauv lub cev (xws li tranexamic acid lossis desmopressin) yog siv los ntawm qhov ncauj lossis tso ntshav thiab ua haujlwm thoob plaws lub cev. Lawv tuaj yeem ua neej nyob -txuag hauv cov xwm txheej zoo li hemophilia lossis kev raug mob loj tab sis muaj kev pheej hmoo suav nrog:
Muaj kev pheej hmoo ntawm thromboembolic cov xwm txheej (cov ntshav txhaws hauv cov hlab ntsha sib sib zog nqus, lub ntsws, lossis lub hlwb)
Muaj peev xwm ua xua
Xav tau kev saib xyuas kev kho mob thiab kev suav tshuaj
Qhov zoo ntawm absorbable hemostatic hais:Lawv muab kev ua haujlwm hauv cheeb tsam nkaus xwb ntawm qhov chaw los ntshav, nrog tsawg heev kom tsis muaj kev nqus dej. Qhov no txo cov kev pheej hmoo ntawm kev mob tshwm sim.
3. Mechanical Hemostatic Agents (Tourniquets)
Tourniquets are highly effective in controlling life-threatening extremity bleeding but must be used with caution. Prolonged tourniquet application (typically >2 teev) tuaj yeem ua rau:
Ischemic cov ntaub so ntswg puas
Ntshai raug mob
Compartment Syndrome
Limb poob hauv cov xwm txheej hnyav
Qhov zoo ntawm absorbable hemostatic hais:Lawv txhawb nqa ntuj clotting yam tsis muaj kev cuam tshuam cov ntshav ntws mus rau cov ntaub so ntswg noj qab haus huv. Lawv tsis ua rau ischemia lossis siab - cuam tshuam txog kev puas tsuaj.
Qhov zoo ntawm Absorbable Hemostatic Particles
Raws li cov ntaub ntawv kho mob thiab cov qauv tsim khoom, cov txiaj ntsig tseem ceeb suav nrog:
| Feature | Tau txais txiaj ntsig |
|---|---|
| Absorbability | Tsis tas yuav tsum tau phais mob los yog tshem tawm |
| Yooj yim ntawm kev thov | Yooj yim sprinkle- ntawm cov txheej txheem, haum rau kev siv thaum muaj xwm ceev |
| Biocompatibility | Tsis tshua muaj kev pheej hmoo ntawm kev ua xua lossis txawv teb chaws lub cev teb |
| Ntau yam | Siv tau rau kev phais mob, kev raug mob raug mob, thiab los ntshav me |
| Kev ua hauv zos | Tsis muaj kev phiv tshwm sim |
Cov pov thawj kho mob txhawb nqa Absorbable Hemostatic Particles
Ntau tus phooj ywg- cov kev tshawb fawb tshuaj xyuas tau ntsuas qhov ua tau zoo ntawmabsorbable hemostatic hais. Kev tshawb fawb luam tawm hauv cov ntawv xov xwm xws li covPhau ntawv Journal of Trauma and Acute Care SurgerythiabBiomaterialstau qhia tias:
Absorbable hemostatic particles ua tiav hemostasis sai dua li cov ntaub qhwv ntsej hauv ob qho tib si tsiaj qauv thiab kev sim tib neeg
Cov txheej txheem nqus tau ua tiav hauv 4-8 lub lis piam yam tsis muaj qhov mob loj lossis adhesions
Cov khoom no muaj txiaj ntsig zoo txawm tias nyob rau hauv cov neeg mob uas mob me mus rau nruab nrab coagulopathies
