Metabolism time of anesthetics: if it is general anesthesia, most drugs are metabolized in half, usually, half of the anesthetic drugs are metabolized within one day, and it takes about 3 to 4 days for the anesthetic drugs to be completely metabolized. Due to individual differences in physical condition, metabolism may vary, and it may take up to 7 days to be completely metabolized. If it is local anesthesia, the metabolism time of the anesthetic drug in the human body is shorter, about 2 to 3 hours. The metabolism of anesthetic drugs does not affect normal physiological activities, and drinking plenty of water can promote the metabolism of anesthetic drugs.

There are three general methods of administering anesthetics: the first is local anesthesia, the second is epidural anesthesia, and the third is inhalation general anesthesia. Depending on the different methods of anesthesia, the metabolism time of the drugs also varies. Generally, local anesthesia is administered, such as partial infiltration anesthesia is needed for tooth extraction or partial incisions, and the drug used is lidocaine. The metabolism of the anesthetic drug in local anesthesia can be completed in 30 minutes.

　 　 　In the case of epidural anesthesia, it is feasible during appendicitis surgery, subcutaneous tissue surgery, or short-term surgery. The metabolism rate and time are about six hours. During general anesthesia, such as major surgery or major trauma, it is necessary to perform general inhalation anesthesia, and the metabolism of anesthetic drugs requires 24 hours. However, the actual time may vary slightly depending on the individual’s physical condition.

Generally, antibiotics are metabolized in the human body for the most part within a week, but if they are used for a long time or with unique types of antibiotics, the metabolism time may be longer. When women use antibiotics, it is first necessary to confirm whether they are pregnant or have any plans for pregnancy recently. The use of antibiotics during pregnancy is very strict, and it is necessary to have a confirmed disease and use the most basic antibiotics, selecting the minimum effective dose. If antibiotics are used during the period of preparing for pregnancy, they also need to be strictly controlled, and some antibiotics that are easier to metabolize and have a shorter half-life should be selected. When antibiotics are used without knowing the pregnancy status, it needs to be determined according to the type of antibiotic and the duration of use.
