People sometimes stretch the word in writing: a loud, busy city can “anaesthetize” you, meaning it dulls your feelings — but that is picture-language, not the hospital use. Though actually, the medical verb is about stopping feeling on purpose and under control, not about making someone vaguely sleepy. After a local anaesthetic you are still awake; after a general one you are not.

People sometimes stretch the word in writing人們在寫作裡有時候會把這個字用得更寬： a loud, busy city can “anaesthetize” you一座吵鬧繁忙的城市可以'anaesthetize'你， meaning it dulls your feelings意思是讓你的感覺變遲鈍—— but that is picture-language, not the hospital use但這是比喻用法，不是醫院裡的用法。 Though actually其實， the medical verb is about stopping feeling on purpose and under control醫學上的這個動詞說的是刻意、可控制地讓感覺停止， not about making someone vaguely sleepy而不是讓人模模糊糊地想睡。 After a local anaesthetic you are still awake打了局部麻醉之後你還是醒著， after a general one you are not打了全身麻醉就不是了。
