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.

Comparative StudyThe effects of dexmedetomidine on myogenic motor evoked potentials in rabbits.
Dexmedetomidine is used in the perioperative management of patients, including as an intraoperative adjuvant. The effects of dexmedetomidine on myogenic motor evoked potentials (MEPs) remain undetermined. We conducted the present study to investigate the effects of dexmedetomidine on myogenic MEPs in rabbits. ⋯ As long as multipulse is used for stimulation, the recording of myogenic MEPs is feasible in rabbits under ketamine and fentanyl anesthesia during the administration of dexmedetomidine at doses that are an adjunct to anesthesia.

Randomized Controlled Trial Comparative StudyThe effects of morphine and fentanyl on the inflammatory response to cardiopulmonary bypass in patients undergoing elective coronary artery bypass graft surgery.
Experimental data suggest that morphine has unique antiinflammatory properties. We hypothesized that morphine, when compared with fentanyl, would attenuate the perioperative inflammatory response to cardiopulmonary bypass (CPB) when administered as part of a balanced anesthetic technique. ⋯ Compared with fentanyl, the administration of morphine as part of balanced anesthetic technique suppressed several components the inflammatory response (IL-6, CD 11b, CD 18, postoperative hyperthermia) to cardiac surgery and CPB.
