Hauv kev xaus, cov khoom siv hluav taws xob ntau zaus yog cov cuab yeej tseem ceeb thiab muaj zog hauv cov txheej txheem phais niaj hnub no, tab sis qhov muaj peev xwm rau kev kub hnyiab thaum lawv siv tsis tuaj yeem raug saib xyuas.
Txhawm rau tiv thaiv cov kab mob no, yuav tsum tau ua ntau yam kev ntsuas. Cov neeg ua haujlwm kho mob, cov neeg ua haujlwm kho mob, thiab txhua tus neeg koom nrog hauv cov txheej txheem phais yuav tsum muaj kev nkag siab tob txog qhov ua rau kub hnyiab no thiab kev tiv thaiv. Los ntawm nruj me ntsis raws li cov tswv yim tiv thaiv, qhov tshwm sim ntawm kub hnyiab los ntawm high-frequency electrosurgical units tuaj yeem txo qis. Qhov no tsis tsuas yog ua kom muaj kev nyab xeeb ntawm cov neeg mob thaum lub sijhawm phais tab sis kuj tseem ua rau muaj kev vam meej ntawm cov txheej txheem phais, txhim kho tag nrho cov kev ua tau zoo thiab kev ua tau zoo ntawm kev kho mob phais. Nyob rau hauv lub neej yav tom ntej, kev tshawb fawb txuas ntxiv thiab kev txhim kho hauv kev tsim thiab kev siv cov khoom siv hluav taws xob ntau zaus yuav tsum tau ua kom muaj kev nyab xeeb ntxiv rau kev phais thiab cov txiaj ntsig ntawm tus neeg mob.
