| Kev pab thawj zaug |
Yog hais tias cov tshuaj no nkag mus rau hauv lub qhov muag, tshem tawm ib qho kev sib cuag lo ntsiab muag ib zaug thiab irrigate tam sim ntawd rau tsawg kawg yog 15 feeb, qee zaus nqa lub hau sab sauv thiab qis dua. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no cuam tshuam rau ntawm daim tawv nqaij, tshem cov khaub ncaws tsis huv thiab ntxuav tam sim nrog xab npum thiab dej. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no tau nqus tau lawm, tshem tawm ntawm qhov raug, pib ua pa cawm siav (siv kev ceev faj thoob ntiaj teb, suav nrog daim npog qhov ncauj resuscitation) yog ua tsis taus pa thiab CPR yog tias lub plawv nres. Hloov tam sim ntawd mus rau qhov chaw kho mob. Thaum cov tshuaj no tau nqos lawm, mus kho mob. Muab dej ntau thiab ua kom ntuav. Tsis txhob ua rau tus neeg tsis nco qab ntuav. Kev soj ntsuam kho mob tau pom zoo rau 24 48 teev tom qab ua pa ntau dhau, vim tias pulmonaryedema tuaj yeem ncua sijhawm. Raws li kev pab thawj zaug rau pulmonary edema, kws kho mob lossis kws kho mob tau tso cai yuav txiav txim siab siv tshuaj corticosteroid. |
| khaws cia |
Xim Code-Red: Flammability Hazard: Khaws rau hauv qhov chaw cia cov kua hluav taws xob los yog lub txee tso cai kom deb ntawm qhov hluav taws kub thiab cov khoom siv corrosive thiab reactive. Tiv thaiv kev puas tsuaj rau lub cev. Ua ntej nkag mus rau hauv qhov chaw kaw qhov chaw uas cov tshuaj no tuaj yeem tshwm sim, xyuas kom paub tseeb tias tsis muaj cov khoom tawg. Sab nraud detached cia yog nyiam. Ua ntej ua haujlwm nrog butylmethacrylate koj yuav tsum tau kawm txog nws txoj kev tuav thiab khaws cia. Khaws rau hauv cov thawv kaw nruj nreem nyob rau hauv qhov chaw txias, zoo-ventilated kom deb ntawm cov ntaub ntawv tsis sib xws saum toj no thiab los ntawm lub teeb thiab cua sov. Butyl methacrylate yuav tsum tau khaws cia hauv tub yees thiab inhibited nrog 10-ppmhydroquinone monomethylether. Cov thawv hlau uas cuam tshuam txog kev hloov pauv ntawm cov tshuaj no yuav tsum tau ua hauv av thiab sib txuas. Nruas yuav tsum tau nruab nrog tus kheej-kaw li qub, lub tshuab nqus tsev bungs, thiab nplaim taws ntes. Siv cov cuab yeej thiab cov cuab yeej uas tsis muaj teeb meem, tshwj xeeb tshaj yog thaum qhib thiab kaw cov ntim ntawm cov tshuaj no. Qhov chaw ntawm qhov hluav taws kub, xws li haus luam yeeb thiab qhib nplaim taws, yog txwv tsis pub siv cov tshuaj no, tuav, lossis khaws cia rau hauv ib qho uas yuav ua rau muaj hluav taws kub lossis tawg. |
