I had 4 hour brain surgery. How long does take for all of the effects of anesthesia to go away?

In brief: See below

Usually the effects of anesthesia are gone within three days.
There is a concern, with the extremes of age, that there may be some effects on cognitive ability with prolonged anesthesia. Talk to your anesthesiologist if you are continuing to have symptoms. Remember these may also be related to the type of surgery you had. Good luck.

In brief: Quick

Assuming there were no complications most of the effects should be gone in 24 hours.
If excessive amount of benzodiazepines was used it could be a few days longer. If you are concerned, contact your anesthesia provider. Most side effects you see after major surgery could be related to surgery itself or narcotic use.

In brief: It depends

This will depend on the type of anestheti given however short-acting a esthetics are typically used.
All effects should be gone by the following day. There can still be sleep disturbances and other side effects of pain medications.

In brief: Surgical Post Op

This is a question best answered by your surgery team they know what specific anesthesia was used and at what doses.
Any answer here would be pure speculation.
