5.Epidural block: cov concentration ntau yog 0.15 ~ 0.3% tshuaj, ua ke nrog lidocaine hydrochloride, qhov siab tshaj plaws yog 0.3%, qhov ntau npaum li cas yog 40 ~ 50mg ib zaug, thiab qhov siab tshaj plaws yog 80mg.Subarachnoid block: nws cov tshuaj tov (1ml ntawm 1% tetracaine hydrochloride tov nrog 1ml ntawm 10% qabzib txhaj tshuaj thiab 1ml ntawm 3% ephedrine hydrochloride tov nrog chemicalbook) feem ntau yog siv.Qhov ntau npaum li cas yog 10mg ib zaug, 15mg yog qhov txwv, thiab 20mg yog qhov siab tshaj plaws.Nerve conduction thaiv: cov concentration yog 0.1% ~ 0.2%, qhov ntau npaum li cas yog 40 ~ 50mg ib zaug, thiab qhov siab tshaj plaws yog 100mg.Mucosal deg tshuaj loog: cov concentration yog 1%, ophthalmology siv 1% isotonic tov, otorhinolaryngology siv 1 ~ 2% tov, thiab qhov txwv ntawm ib zaug yog 40mg.
Daim ntawv thov
Qhov kev siv tshuaj loog hauv zos yog 10 npaug ntawm procaine, thiab cov nyhuv tuaj yeem kav ntev li 2 ~ 3H, nrog rau kev nkag mus tau zoo.Nws yog tsuas yog siv rau qhov chaw tshuaj loog ntawm qhov muag, qhov ntswg, caj pas thiab tso zis.Tom qab nqus tau, nws tuaj yeem ua rau convulsion, thiab tom qab ntawd tig mus rau kev nyuaj siab ua pa.Feem ntau, nws tsis yog siv rau tshuaj loog xws li infiltration thiab conduction.
