ReviewRemifentanil-induced hyperalgesia: the current state of affairs.
Remifentanil-induced hyperalgesia (RIH) is a part of a general opioid-induced hyperalgesia (OIH) syndrome, seemingly resulting from abrupt cessation of continuous remifentanil infusion at rates equal or exceeding 0.3 mcg/kg/min. The intricate mechanisms of its development are still not completely understood. ⋯ Several ways of prevention and management have been suggested, such as slow withdrawal of remifentanil infusion, the addition of propofol, pretreatment with or concomitant administration of ketamine, buprenorphine, cyclooxygenase-2 inhibitors (NSAIDs), methadone, dexmedetomidine. In clinical and animal studies, these strategies exhibited varying success, and many are still being investigated.

This review article explores the evidence regarding sugammadex (MSD Australia) and its potential interaction with hormonal contraceptives. The impact of recent clinical trials and review articles is examined. ⋯ Strong clinical evidence to support or refute claims of a significant impact of sugammadex on contraceptive efficacy in women on contraception is lacking. The existing evidence does not suggest a basis for concern regarding the impact of sugammadex on contraception in the perioperative setting.
