How to prevent Complex Regional Pain Syndrome from occurring postsurgically?
Although trial data is conflicting, vitamin C 500 mg daily for 50 days is a low-risk intervention that may reduce the prevalence of CRPS in patients who had wrist fractures or lower limb injuries. Some use vitamin C to prevent CRPS after carpal tunnel syndrome surgery. In patients with a previous history of CRPS, perioperative stellate ganglion block or IV mannitol may reduce the recurrence rate of CRPS.
