|
Lidocaine |
Onset 3 mins.. Intense and longer CNS effect: drowsiness mental clouding,dysphoria,altered taste and tinnitus. Overdose:muscle twitching, convulsions, cardiac arrhythmia, fall in bp, coma , respiratory arrest |
|
|
|
Prilocaine |
Like lidocaine Onset 15 mins... Does not cause vasodialation. Lower CNS toxicity( high Vd and fast clearance) May cause Methaemoglobinemia.. |
|
|
|
Bupivacaine |
More lipophilic. Slow onset.. Epidural - painless delivery (also not affect fetus. Y?)
Prolong QT, induce ventricular tachycardia.. Highly cardiotoxic( trt: lipid emulsion infusion) |
Levobupivacaine : s enantiomer..less cardiotoxic |
|
|
Ropivacaine |
Long acting congener of bupi. Less cardiotoxic and CNS toxic Lower lipid soluble Differential block... sensory first |
|
|
|
Tetracaine (amethocaine) |
Highly lipid soluble PABA ester. More potent and MORE TOXIC( slow hydrolysis by plasma pseudocholinestrase... Contraindicated in Bronchoscopy |
|
|
|
Proparacaine(proxymetacaine) |
Opthlamic anasthetic |
|
