What are the reported uses of lidocaine in medical practice according to the chapter on local anaesthesia?

Lidocaine is used in medical practice primarily as a local anaesthetic for procedures such as dental surgery, minor surgical operations, and intravenous regional anaesthesia. Additionally, it serves as an antidysrhythmic agent and is reported to treat premature ejaculation when applied topically before intercourse.

Lidocaine is one of the most commonly used local anaesthetics due to its rapid onset and intermediate duration of action. It is frequently employed in dental procedures and various minor surgical interventions. Beyond its anaesthetic properties, lidocaine is also utilized intravenously as an antidysrhythmic. An interesting application is its use in treating premature ejaculation, where it is sprayed on the penis to desensitize receptors and delay ejaculation.
