Pramipexole-responsive acute restless arms syndrome after surgery under general anesthesia: Case report and literature review.

We reported a case of acute restless arms syndrome occurring after colorectal surgery under general anaesthesia. This case was also compared with other cases of restless legs/arms syndromes occurring in a perioperative context through a literature review. As the restless legs syndrome, the restless arms syndrome can be exacerbated by perioperative procedures and improved with pramipexole from the first day of treatment. This case reinforces the idea that the restless arms syndrome seems to be subsumed along with the restless legs syndrome, and is a further argument to use the diagnosis term "restless limb syndrome" for the restlessness of any limb with clinical features similar to the restless legs syndrome.
