When patients undergo surgery with a peripheral nerve block, they often experience a sudden return of pain once the local anesthetic wears off. This is known as rebound pain. Managing this transition is a major hurdle for patient comfort and recovery.
Researchers looked at data from 2,130 adults to see which medications worked best. They found that intravenous dexamethasone had the highest probability of reducing the occurrence of rebound pain. Other options, like perineural dexamethasone and perineural dexmedetomidine, were found to be the best at delaying the start of that pain and extending the time before a patient needed rescue medication.
While these findings are promising, the evidence is not perfect. The certainty of the data ranged from very low to moderate. Additionally, because researchers could not consistently measure things like patient satisfaction or sleep quality, those specific factors remain unclear. Talk to your doctor about these options to see if they fit your specific surgical plan.
