Why Do We Feel Cold and Shiver After Anesthesia?
Many patients say the first thing they remember after an operation is shivering.
It is very common, and in most cases not dangerous.
Why does it happen?
During anesthesia:
- Body temperature can fall
- Temperature regulation can be temporarily affected
- The operating room can be cool
- Shivering can appear as the body tries to return to its normal temperature
Is it dangerous?
Usually not. In some respects it shows that the body's normal defence mechanism is working. Excessive shivering can be treated.
How is it treated?
- Warming blankets
- Forced-air warming systems
- Medication where needed
Is it more common in children?
Yes. Children lose body heat more quickly, which is why temperature management during surgery matters a great deal in their case.
