“How do you detox after general anesthesia?”

What is detox. You have functioning liver, kidneys and lung. They do the job for you.

Medication metabolized. Drink plenty of fluids and get good sleep.

I'm sorry, but I do not understand your question, or the basis for your question of a "detox" following general anesthesia. Medications used to accomplish general anesthesia have "built-in" clearance mechanisms. While those medications provide very powerful effects on the body (specifically the nervous system) to provide loss of sensation of pain or the provision of complete unconsciousness, they function in only a temporary manner. In general, there is no other substance that can be added to the body to "detox" anesthetic agents (which I'm interpreting to mean you are asking about a way to make anesthetic agents leave the body more rapidly). If you mean something different by your question, please re-ask in a different manner. I may be misunderstanding your question. But all anesthetic agents have only temporary effects in the body. They are specifically intended to have only short-term actions, and have actions that generally can be well controlled by the physician anesthesiologist or nurse anesthetist who is administering those substances.

Hi,

Generally, today’s anesthesia medications are broken down pretty rapidly in your body so you probably don’t have the need to detox. You will probably need to hydrate and rest after your procedure. 

Rest, plenty of water, no alcohol, no smoking, no drugs, plenty of fruits and vegetables, and multivitamins.
