Introduction
The effect of anesthesia usually wears off within 1 to 3 hours, depending on the type of anesthetic and individual differences. If a standard local anesthetic is used and the patient is in good health, the numbness typically subsides within 1 to 2 hours; however, if a long-acting general anesthetic is administered, it may take 2 to 3 hours to wear off. It is advisable to avoid sudden strenuous activities, keep the body warm to promote blood circulation, and pay attention to bodily sensations during recovery.
Generally, anesthetics wear off within 1 to 3 hours, depending on the type of anesthetic used and individual factors. If a standard local anesthetic is used and the person is in good health, the effect usually wears off within 1–2 hours; however, if a long-acting general anesthetic is administered, it may take 2–3 hours to wear off. Specific details are as follows:
If a conventional local anesthetic such as lidocaine is used, which involves local anesthesia, and the individual is healthy, the body absorbs the drug more quickly. Typically, within 1–2 hours after injection, the anesthetic is absorbed and metabolized, and its effects gradually diminish.
If a long-acting general anesthetic such as ropivacaine or bupivacaine is used, and the individual is elderly or has impaired liver or kidney function, metabolism of the anesthetic may be slower, potentially prolonging the duration of action. In such cases, the anesthetic effect generally wears off after 2–3 hours.
In daily life, one should avoid sudden strenuous activity, maintain body warmth to promote blood circulation, and pay attention to bodily sensations.
