hi


Many patients experience some shivering after a general anesthetic. This can also occur with epidural anesthesia. Occasionally the shivering is quite severe, with shaking movements. It cannot be controlled by voluntary effort and is obviously rather uncomfortable.


The reason shivering occurs after general anesthesia has to do with loss of body heat that occurs in a cold operating room, but is also related to resetting of the body’s thermostat which happens during anesthesia. Interestingly, shivering can occur after surgery even if your body temperature is normal.


The risk of shivering can be reduced (but not eliminated) by maintaining body temperature while you are in surgery. There are several ways to do this, which include special warming blankets, heating the intravenous fluids, and keeping the operating room at a higher temperature (surgeons do not enjoy this!)

A particular pain medication called meperidine (Demerol) has been shown to effectively control, or perhaps even prevent postoperative shivering, and your anesthesiologist might consider using this drug when you have your next surgery.

Don’t forget to mention this problem to your anesthesiologist before you have your surgery. It would be helpful if you could obtain the records of your previous anesthetic for his or her review.


Hope that helps!

Thank you so much, I really had terrible shaking for a few hours after my last 2 knee surgeries and all the heating blankets could not seem to get me warm. Thanks for your advise i will mention it to the anesthesiologist. Sally Dunn
