Can anesthesia cause shaking?

I am a 29 year old female. I heard of someone getting the shakes after having anesthesia. I want to know if anesthesia can cause shaking?

Yes. It's called shivering. It's due to the body trying to increase your body temperature because of the hypothermia produced by anesthesia and surgery.
Yes, but rare.
Usually shaking after anesthesia is due to body’s temperature drop during surgery, particularly longer cases. Shaking is body’s way of warming up.

From Christopher Creighton
Yes...fairly common side effect. It’s short-lived and easily treated with a small dose of Demerol.
Tremors after anesthesia are uncommon. The reason that they occur is not known, but they are usually easily treated with intravenous medications.
Yes, it can. As anesthesia works on the central nervous system, it affects the hypothalamus. Upon emergence from anesthesia, the hypothalamus awakens and can cause patients to shiver in the recovery room.
Hope that answers your question.

Yes. General anesthesia results in a state of poikilothermia, i.e., a state in which body temperature approaches room temperature. So, post-op shivering can be minimized by keeping the patient warm during surgery with modalities such as forced-air warming blankets and minimizing exposed body parts. Also, a dose of Demerol prior to emergence can inhibit post-op shivering.
