How long after general anesthesia is it completely out of your system?

Depends on drugs: General anesthesia isn't just one medication--it's a combination. Some induce sleep, some (like the anesthesia gases) maintain sleep, some relax muscles, some relieve pain, etc. Each is metabolized at a different rate. In general, you can expect them to vanish within 6-8 hours, but it will take longer if the kidneys or liver don't work well. Don't drive within 24 hours of having anesthesia. ...Read more

How long before general anesthesia is out of your system?

It depends : On what was used, how long it was used for and how well the patients body metabolizes and clears the medication. For most modern anesthetics, the majority of the medication will clear within a few hours. Some people can have prolonged residual effects. ...Read more

How long after general anesthesia do I need to abstain from breastfeeding?

Depends: It depends on what agents are used for the general anesthesia. The best resource is to ask the anesthesiologist who is sedating you. If you received propofol then it is recommended that you "pump and dump" for 48 hrs after the sedation. Inhaled anesthetics should be out of the system fairly quickly. Pain medications and anxiolytics have different half-lives depending on which is used. ...Read more

Does general anesthesia have a long-term effect on the memory after the operation?

Rarely: There is evidence to suggest that rarely general anesthesia can result in long-term memory loss. This is mostly found in very elderly patients having major operations such as heart surgery and joint replacement. Millions of patients have had general anesthesia with no problems whatsoever in the postoperative period. Younger patients typically wake up feeling exactly the same as before. ...Read more

How long do the effects of general anesthesia last after the srugery is over?

Several hours.: Most patients are awake almost immediately after anesthesia. However, the effects last several hours making the patient's sleepy and groggy. Often patients have no memory of being in recovery room, and this is the lingering effects of the anesthesia. This situation is compounded by the pain medications/narcotics that you will have after the surgery. ...Read more

Another thought: Many lactation consultants are now instructing patients that there is no need to pump and dump from one exposure to general anesthesia. The amount that makes it to the milk is extremely small. Personnel preference must be respected however. There is no harm in dumping for 24 hrs. I agree though have a talk with your anesthesiologist. ...Read more

How long will I be sleepy for after general anesthesia?

Depends: Depending on the surgery, you will wake up right after the surgery is done. As for the drowsiness well....some people claim they are ready to rock and roll right after and some people say it took them a full month to regain their sleep cycle. Hopefully the former and not the latter. ...Read more
