Hemostatic hnav khaub ncaws pab kom tsis txhob los ntshav. Lawv txhawb lub cev hemostasis. Cov hnav khaub ncaws no siv cov khoom tshwj xeeb los tswj cov ntshav poob sai. Nws yog ib qho tseem ceeb kom paub tias hemostatic ua haujlwm li cas. Cov kws kho mob thiab lwm tus yuav tsum tswj cov ntshav.
Ntsiab Cai
Hemostatic hnav khaub ncawspab nres los ntshav sai. Lawv siv cov ntaub ntawv tshwj xeeb uas ua rau lub cev ua rau cov hlab ntsha sai dua li kev hnav khaub ncaws li niaj zaus. Ntau hom kev hnav khaub ncaws hemostatic, xws li chitosan thiab kaolin, ua haujlwm hauv lawv tus kheej txoj hauv kev los tswj ntshav. Qhov no ua rau lawv tseem ceeb heev hauv kev kub ntxhov thiab kev phais. Paub tias cov ntaub ntawv hemostatic ua haujlwm li cas tuaj yeem ua rau kev kho mob zoo dua. Nws tseem tuaj yeem cawm txoj sia los ntawm kev ua kom cov ntshav tau kho sai thiab zoo.
Hemostatic Dressings Txheej txheem cej luam
Hemostatic Dressings yog dab tsi?
Hemostatic dressings yog cov khoom kho mob tshwj xeeb uas pab kom tsis txhob los ntshav. Lawv siv cov khoom siv tshuaj hemostatic siab heev los pab lub cev tsim cov hlab ntsha. Cov hnav khaub ncaws no ua haujlwm sai dua li cov ntaub qhwv lub qhov txhab. Lawv tsis yog nyob ntawm lub cev ntawm tus kheej txheej txheem. Cov tshuaj hemostatic hauv cov khaub ncaws no sib xyaw nrog cov ntshav kom tsis txhob los ntshav sai.
Muaj peb hom kev hnav khaub ncaws hemostatic. Txhua hom ua haujlwm sib txawv:
| Qeb | Lawv ua haujlwm li cas |
|---|---|
| Factor concentrators | Tshem cov dej tawm ntawm cov ntshav thiab ua kom cov hlwb thiab cov protein ntau dua |
| Cov tshuaj mucoadhesive | Lo rau ntawm qhov txhab thiab thaiv cov ntshav |
| Procoagulant supplementors | Ntxiv cov khoom ua kom muaj kuab paug rau ntawm qhov txhab |
Cov tshuaj pleev hemostatic no siv rau ntau qhov kev raug mob. Lawv pab kho qhov txhab uas los ntshav ntau.
Yuav Ua Li Cas Hemostatic Dressings Ua Haujlwm
Kev hnav khaub ncaws hemostatic siv cov khoom siv tshuaj hemostatic los pab kom ntshav khov sai. Lawv ua haujlwm los ntawm kev siv ob qho tib si lub cev thiab tshuaj. Qee cov neeg ua haujlwm rub dej tawm ntawm cov ntshav, ua rau nws tuab dua thiab pab ua kom khov. Lwm cov neeg ua haujlwm lo rau ntawm qhov txhab thiab kaw nws kom tsis txhob los ntshav. Qee qhov kev hnav khaub ncaws ntxiv ntau yam ua rau lub qhov txhab, uas yuav pab tau txawm tias tus neeg muaj teeb meem hauv plab.
Cov khoom siv tshuaj hemostatic no ua haujlwm zoo dua li kev hnav khaub ncaws niaj hnub. Piv txwv li, chitosan thiab alginate- cov ntaub ntawv raws li tuaj yeem nqus ntshav hauv vib nas this xwb. Kev hnav khaub ncaws tsis tu ncua siv sijhawm ntev dua los ua qhov no. Kev nrawm nrawm yog qhov tseem ceeb heev hauv kev kho mob vim tias txhua qhov thib ob tseem ceeb. Cov ntaub ntawv hemostatic raug xaiv rau lawv lub peev xwm los ntshav sai thiab nyab xeeb. Cov neeg sawv cev no yog siv ob qho tib si thaum muaj xwm txheej ceev thiab phais mob los pab kom tsis txhob los ntshav.
Hemostasis thiab txheej txheem clotting
Ntuj hemostasis hauv lub cev
Hemostasis yog li cas lub cev nres los ntshav tom qab raug mob. Lub cev siv ob peb kauj ruam los tiv thaiv cov hlab ntsha thiab cov ntaub so ntswg. Thaum koj raug mob, koj lub cev ua haujlwm nrawm kom tsis txhob poob ntshav. Cov lus hauv qab no qhia covcov kauj ruam ntawm ntuj hemostasis:
| Kauj ruam Number | Kauj ruam npe | Kev piav qhia |
|---|---|---|
| 1 | Vascular Spasm | Cov hlab ntsha me me kom pab txo qis ntshav. |
| 2 | Platelet Plug Tsim | Platelets lo ua ke thiab ua kom nrawm nrawm ntawm lub nkoj tawg. |
| 3 | Coagulation | Fibrin threads ua rau cov platelet ntsaws ruaj khov thiab tsim cov ntshav khov. |
Txhua kauj ruam siv cov khoom tshwj xeeb hemostatic hauv lub cev. Platelets thiab proteins ua haujlwm ua ke los kaw qhov txhab. Cov txheej txheem txhaws ntshav nres ntau dua thiab ua kom cov ntaub so ntswg kom tsis txhob raug mob. Kev hnav khaub ncaws hemostatic tuaj yeem pab cov kauj ruam no los ntawm kev ua cov platelets los ua ke thiab pib coagulation cascade. Qee cov ntaub ntawv ua rau muaj kev cuam tshuam rau lub qhov txhab, uas pab lub cev kom tsis txhob los ntshav zoo.
Vim li cas Rapid Hemostasis yog qhov tseem ceeb
Tsis txhob los ntshav sai yog qhov tseem ceeb heev hauv kev kho mob. Kev ua sai sai tuaj yeem cawm tau txoj sia thiab nres teeb meem loj. Yog tias cov ntshav tsis nres sai sai, tuaj yeem ua rau cov ntshav poob ntau dua thiab lub cev puas tsuaj. Cov kev tshawb fawb qhia tau hais tias tso tseg los ntshav sai dua qhov qis duapheej hmoo ntawm teeb meemxws li mob raum, sepsis, thiab lub cev tsis ua haujlwm. Cov npe hauv qab no qhia tias yuav ua li cas tshwm sim yog tias hemostasis qeeb:
Kev tuag ntau dua hauv cov neeg mob raug mob
Muaj teeb meem ntawm lub cev
Kev poob ntshav ntau dua thiab tsis muaj oxygen rau hauv lub cev
Muaj teeb meem ntxiv xws li ARDS thiab sepsis
Kev siv cov khoom hemostatic sai sai yog qhov tseem ceeb thaum muaj xwm txheej ceev. Ntau tshaj 30% ntawm cov neeg uas tuag los ntawm kev raug mob los ntshav ntau dhau. Hauv cov tub rog, yuav luag ib nrab ntawm cov neeg raug mob xav tau hemostasis zoo dua thiab phais sai. Ntau tus neeg tuag ua ntej kev pab tuaj txog, yog li yuav tsum tau ceev cov ntshav ntawm qhov chaw. Hemostatic hnav khaub ncaws thiab cov ntaub ntawv tseem ceeb rau kev tso ntshav thiab pab cov neeg mob kom zoo.
Hom Hemostatic Dressings
Kev hnav khaub ncaws hemostatic raug txheeb xyuas raws li lawv tso tseg los ntshav. Txhua hom ua haujlwm ntawm nws tus kheej los pab hemostasis thiab tswj los ntshav. Cov ntaub ntawv muaj zog no yog siv hauv kev phais thiab kho qhov txhab.
