ReviewMagnesium as an adjuvant to postoperative analgesia: a systematic review of randomized trials.
Randomized trials have reached different conclusions as to whether magnesium is a useful adjuvant to postoperative analgesia. ⋯ These trials do not provide convincing evidence that perioperative magnesium may have favorable effects on postoperative pain intensity and analgesic requirements. Perioperative magnesium supplementation prevents postoperative hypomagnesemia and decreases the incidence of postoperative shivering. It may be worthwhile to further study the role of magnesium as a supplement to postoperative analgesia, since this relatively harmless molecule is inexpensive, and the biological basis for its potential antinociceptive effect is promising.

Randomized Controlled Trial Comparative StudyAn evaluation of a single dose of magnesium to supplement analgesia after ambulatory surgery: randomized controlled trial.
Previous studies have suggested that magnesium may be a useful adjuvant to postoperative analgesia. ⋯ In patients undergoing ambulatory ilioinguinal hernia repair or varicose vein operations under general anesthesia supplemented with other analgesic adjuvants, pretreatment with IV magnesium sulfate 4 g has no impact on postoperative pain and analgesic consumption.

Randomized Controlled Trial Comparative StudyMultimodal analgesia to prevent propofol-induced pain: pretreatment with remifentanil and lidocaine versus remifentanil or lidocaine alone.
Propofol is well-known for its pain on injection. Premixture with lidocaine or pretreatment with remifentanil reduces injection pain. A multimodal approach might offer additional mitigation of propofol injection pain. ⋯ The combination of two different analgesic modalities, remifentanil and lidocaine completely abolishes moderate and severe pain associated with propofol injection, and significantly reduces the incidence of mild pain when compared with each drug used alone.

Review Comparative StudyDo surgical patients benefit from perioperative gabapentin/pregabalin? A systematic review of efficacy and safety.
Gabapentin and pregabalin have antiallodynic and antihyperalgesic properties useful for treating neuropathic pain. These properties may also be beneficial in acute postoperative pain. In this study we evaluated randomized, controlled trials examining the analgesic efficacy, adverse effects, and clinical value of gabapentinoids in postoperative pain. ⋯ Gabapentinoids effectively reduce postoperative pain, opioid consumption, and opioid-related adverse effects after surgery. Conclusions about the optimal dose and duration of the treatment cannot be made because of the heterogeneity of the trials. Studies are needed to determine the long-term benefits, if any, of perioperative gabapentinoids.

Randomized Controlled Trial Multicenter Study Comparative StudyThe influence of timing of administration on the analgesic efficacy of parecoxib in orthopedic surgery.
Parecoxib, a selective cyclooxygenase-2 inhibitor, may reduce postoperative pain without increasing bleeding when administered before surgery. ⋯ Administration of parecoxib before hip arthroplasty did not provide preemptive analgesia. There was a trend towards improved analgesia immediately after surgery with preincision administration, consistent with the expected time course of nonsteroidal antiinflammatory drug's effect. Perioperative parecoxib administration, consisting of two injections spaced 12 h apart, improved postoperative analgesia over the first 24 h without increasing bleeding.
