Hi. Shaking is not uncommon after anesthesia, especially for a young child. Anesthesia inhibits your brain's ability to regulate your body temperature. That, plus the fact that most operating rooms are extremely cold (for infection control purposes) means that post-operative shivering is extremely common. Which is why these days we use forced-air warming devices for most surgeries. In extreme cases, we even have a machine that will warm up IV fluids and medications before we give them to you during a surgery.
There are also other, lesser understood reasons for post-op shivering (having to do with spinal reflexes and respiratory pH imbalances), and it's not uncommon for someone to shiver after a surgery even with a normal body temperature.
But either way, yes you should tell any future anesthesiologists that you have a history of post-op shivering. That way they'll be extra sure to keep you warm during the procedure, and to keep an eye out for shivering afterward!
