However, opioid-related side effects such as constipation, nausea, vomiting, and respiratory depression often accompany the use opioids. Many studies have evaluated the efficacy of nonopioids such as ketamine, lidocaine, naloxone, and magnesium as perioperative infusions to decrease postoperative pain and minimize the use of opioids after surgery. Infusions of the short-acting beta-blocker esmolol and the α2 agonist dexmedetomidine have also been investigated as adjuvants to reduce the postoperative opioid requirement. In this chapter, the results of the studies on infusions of ketamine, lidocaine, naloxone, esmolol, α2 agonists, and magnesium will be summarized, and recommendations on their clinical applicability as part of perioperative pain management will be made.
