Introduction and Role of Lidocaine Base:
1.Lidocaine base is a fast-acting local anesthetic suitable for infiltration, block and topical anesthesia, Epinephrine vasoconstricts arteries, flexible bleeding and also delays the resorption of lidocaine, almost doubling the duration of anaesthesia.
2.Lidocaine base can relieve the pain of post-herpetic neuralgia (complication of herpes zoster), and can also treat temporary tinnitus. Although it can not be used as the main product of treatment, it can also play a certain therapeutic role.
3.In addition, inhaled lidocaine can also be used as a peripheral antitussive (cough suppressant) to reduce cough reflexes because it reduces the incidence of cough and any tracheal damage that may occur during anesthesia.
4.Lidocaine base and ethanol, ammonia and acetic acid have also been shown to be effective in treating jellyfish spasms, both to paralyze affected areas and to prevent further punctate cell excretion.
