Raws li qee tus neeg uas xav paub txog tshuaj, koj tuaj yeem tau dhau qhov kev qhia "tetracaine"Thiab xav txog nws qhov kev tsis sib haum xeeb. Tetracaine yog ib lub zej zog sedative tsis tu ncua siv hauv kev ua haujlwm sib txawv kom ua rau lub cev tsis meej pem hauv cheeb tsam ntawm lub cev. Kev nkag siab txog nws qhov kev puas tsuaj yog qhov ceev heev rau nws lub koom haum tsim nyog thiab tsim nyog.
Tetracaine yog dab tsi?
Tetracaineyog ib lub zej zog sedative muaj qhov chaw nrog chav kawm ntawm ester-hom sedatives. Nws ua haujlwm los ntawm kev cuam tshuam cov paj hlwb hauv lub cev, ua rau lub sijhawm luv luv ntawm kev hnov qab hauv qhov chaw uas nws siv los yog infused. Qhov kev tuag no txo qis kev tsim txom thiab kev tsis txaus siab thaum ua haujlwm lossis rau kev pab cuam tsis tu ncua ntawm kev mob me me thiab tingling.
Tetracaine yog siv tau nyob rau hauv ntau lub ntsiab lus, nrog rau cov tshuaj pleev ib ce, tshuaj pleev, gels, thiab cov lus teb rau kev siv ophthalmic (qhov muag qhov muag). Nws tseem raug qhia los ntawm kev txhaj tshuaj rau cov leeg txha caj qaum, thaj chaw paj hlwb, thiab qee yam kab mob.
Ib yam li nrog rau txhua yam tshuaj, tetracaine yuav tsum tau siv los ntawm kev tswj hwm ntawm cov kev pabcuam kho mob uas muaj peev xwm los lav qhov kev ntsuas raug cai thiab lub koom haum, nrog rau kev txwv kev twv txiaj ntawm qhov xwm txheej lossis kev cuam tshuam.
Solubility ntawm Tetracaine
Lub dissolvability ntawm ib yam khoom alludes rau nws lub peev xwm mus disintegrate nyob rau hauv ib tug dissolvable, xws li dej los yog cawv. Nyob ntawm tus accounttetracaine, nws yog sparingly hnyav nyob rau hauv dej tab sis ntau dissolvable nyob rau hauv cawv. Cov cuab yeej no yog qhov tseem ceeb rau nws qhov kev nthuav dav rau hauv cov qauv ntsuas sib txawv, piv txwv li, qhov muag tee, tshuaj cawm, thiab cov lus teb rau kev haus dej.
Tej yam cuam tshuam rau solubility
Kub: raws li txoj cai dav dav, kev sib cais yuav nyob rau hauv kev nce ntxiv nrog rau qhov kub thiab txias rau feem ntau cov khib nyiab hauv cov kua ua kua. Txawm li cas los xij, qhov kev sib raug zoo no tuaj yeem hloov pauv mus rau qhov tshwj xeeb ntawm cov khoom thiab cov kev sib cais. Rau tetracaine, nws qhov kev sib cais tuaj yeem nce ntxiv nrog qhov kub thiab txias, txawm li cas los xij nws yuav tsis yog qhov muaj txiaj ntsig zoo ntxiv vim nws txuag cov kuab tshuaj hauv dej.
Siab: Dissimilar rau gases, kev hloov hauv siab tsis tu ncua negligibly cuam tshuam rau lub dissolvability ntawm cov khoom nyob rau hauv cov kua. Hauv qhov no, ntau yam kev ntxhov siab tej zaum yuav tsis cuam tshuam rau kev daws teeb meem ntawm tetracaine hauv paus.
Dissolvable: Qhov kev txiav txim siab ntawm dissolvable enormously cuam tshuam cov solvency ntawm ib yam khoom. Tetracaine yog yaj ntau dua hauv cov kuab tshuaj ntuj xws li ethanol thiab chloroform sib piv nrog dej. Ntau cov kuab tshuaj tuaj yeem siv los tswj cov kev sib cais ntawm tetracaine raws li daim ntawv thov zoo tagnrho.
PH: Lub pH ntawm qhov kev npaj tuaj yeem cuam tshuam qhov hnyav ntawmtetracaine. Hloov cov pH tuaj yeem hloov kho qhov xwm txheej ionization ntawm cov khoom sib txuas, raws li cuam tshuam rau nws qhov kev sib cais. Piv txwv li, tetracaine hydrochloride yog hnyav dua li tetracaine puag vim tias muaj cov tshuaj chloride.
Molecule Size: Cov molecule loj ntawm cov kua nplaum tuaj yeem cuam tshuam nws cov kuab tshuaj. Finely hmoov tetracaine tuaj yeem tawg sai dua qhov sib piv nrog cov khoom loj dua vim tias thaj av nthuav dav nkag mus rau kev sib txuas lus nrog cov khoom tawg.
Kev muaj cov tshuaj co-solvents los yog Surfactants: Ntxiv cov kuab tshuaj los yog cov tshuaj surfactants tuaj yeem txhim kho qhov kev sib cais ntawm tetracaine los ntawm kev ua haujlwm rau solubilize cov compound hauv cov khoom tawg. Cov tshuaj ntxiv no tuaj yeem cuam tshuam lub zog ntawm lub cev thiab ua haujlwm ntawm cov dispersibility ntawm tetracaine atoms nyob rau hauv lub dissolvable.
Daim ntawv thov thiab kev siv
Local tshuaj loog:Tetracainefeem ntau yog siv los ua ib qho tshuaj loog hauv zos rau loog thaj tsam ntawm lub cev thaum cov txheej txheem kho mob xws li kev phais me, kev kho hniav, suturing, thiab kev cuam tshuam dermatological. Nws ua haujlwm los ntawm kev thaiv cov hlab ntsha impulses, yog li tshem tawm ib ntus kev hnov mob hauv qhov chaw tsom.
Tshuaj pleev ib ce: Tetracaine feem ntau yog tsim los rau hauv cov tshuaj pleev ib ce, tshuaj pleev, thiab gels rau kev kho mob thiab khaus khaus cuam tshuam nrog cov tawv nqaij me me, sunburns, kab tom, thiab kub kub me. Cov tshuaj pleev cov tshuaj no muab cov kev mob hauv zos uas tsis tas yuav muaj cov txheej txheem cuam tshuam.
Kev Siv Tshuaj Kho Mob: Tetracaine yog siv hauv ophthalmology ua cov tshuaj pleev qhov muag kom loog ntawm qhov muag (cornea thiab conjunctiva) ua ntej qee qhov kev kuaj qhov muag, cov txheej txheem, lossis kev phais. Nws pab txo qhov tsis xis nyob thiab txo qis reflex tearing thaum cov kev cuam tshuam no.
Spinal Anesthesia: Tetracaine, nrog rau lwm cov tshuaj loog hauv zos, tuaj yeem siv los ntawm kev txhaj tshuaj txha caj qaum (intrathecal lossis epidural) txhawm rau txhawm rau txhawm rau tshuaj loog hauv cheeb tsam rau cov txheej txheem phais uas muaj feem rau hauv plab, plab plab, lossis qis qis. Spinal anesthesia muab loog loog thiab cov leeg nqaij so hauv qis ib nrab ntawm lub cev.
Regional tshuaj loog:Tetracainetuaj yeem ua haujlwm rau cov hlab ntsha hauv cheeb tsam txhawm rau tshuaj loog thaj chaw loj ntawm lub cev, xws li cov ceg tawv lossis lub cev, rau kev phais lossis kev tswj xyuas qhov mob. Cov hlab ntsha no koom nrog kev txhaj tshuaj tetracaine ze rau cov hlab ntsha tshwj xeeb los thaiv kev hnov qab hauv cheeb tsam sib thooj anatomical.
Labor Analgesia: Tetracaine, ua ke nrog lwm cov tshuaj loog hauv zos thiab opioids, yuav siv tau rau epidural analgesia thaum lub sij hawm cev xeeb tub thiab yug me nyuam los muab qhov mob nyem yam tsis muaj kev poob ntawm cov leeg nqaij lossis kev nco qab. Epidural anesthesia pab cov niam tswj kev mob hnyav thaum tseem ceeb toom thiab koom nrog hauv kev yug menyuam.
Diagnostic Procedures: Tetracaine tej zaum yuav ua hauj lwm raws li ib tug tshuaj loog tshuaj pleev ib ce rau tej yam kev kuaj mob, xws li endoscopies, bronchoscopies, thiab catheterizations, kom txo tau qhov tsis xis nyob thiab pab cov neeg mob kev koom tes nyob rau hauv cov kev kuaj no.
Xaus
Hauv kev xaus,tetracaineyog ib qho khoom siv tshuaj muaj txiaj ntsig dav siv los ua tshuaj loog hauv zos rau nws lub peev xwm los ua kom qaug zog ib ntus hauv qee qhov chaw ntawm lub cev. Nws cov ntawv thov nthuav dav ntau yam kev kho mob, suav nrog kev phais, kho hniav, dermatology, ophthalmology, obstetrics, thiab kev tswj qhov mob. Tetracaine tuaj yeem muab tshuaj los ntawm cov tshuaj pleev ib ce, tshuaj kho qhov muag, lossis kev txhaj tshuaj, nyob ntawm qhov kev npaj siv thiab lub hom phiaj anatomical site. Kev nkag siab txog nws cov solubility, yam cuam tshuam rau solubility, thiab ntau yam kev siv yog qhov tseem ceeb rau cov kws kho mob kom ua kom zoo dua nws siv thiab ua kom cov neeg mob kev nplij siab thiab kev nyab xeeb thaum lub sij hawm kho mob.
