Review Meta AnalysisAn evidence based systematic review of remifentanil associated opioid-induced hyperalgesia.
Therapeutic opioid use continues to grow, with greater than a fivefold increase in usage of fentanyl-based products over a 10-year period. Opioids are known for their side-effect profile, including bradycardia and respiratory depression; questions remain, however, regarding lesser known side effects such as opioid-induced hyperalgesia (OIH). ⋯ There is conflicting evidence regarding the existence of remifentanil OIH. Outcomes evaluating measures of hyperalgesia frequently conclude that remifentanil OIH exists, while those evaluating opioid consumption do not. Therefore, remifentanil does induce a degree of hyperalgesia, but we do not believe that it reaches a level of clinical significance that requires prevention. If a significant concern for the development of remifentanil OIH is suspected, we suggest using the least possible effective dose of remifentanil as the primary prevention strategy.
