Shivering is common during recovery from general anesthesia. All general anesthetics produce a dose-dependent decrease in the core temperature, thereby reducing the threshold for thermoregulatory vasoconstriction.' Postanesthetic shivering causes complications, including increased oxygen consumption and elevation of intraocular and intracranial pressures2 During recovery, brain anesthetic concentrations decrease rapidly, leaving the patients hypothermic but no longer ane~thetized.~ This triggers vasoconstriction and shivering. The classical pharmacological approach to the treatment of postanesthetic shivering is administration of me~er id ine .~ It is far more effective than equianalgesic doses of other opioids. It was previously reported that clonidine, an alpha-2 adrenergic receptor agonist, and ketanserin, a 5-hydroxytriptamine receptor antagonist, are effective treatment for postanesthetic hiver ring.^.' Magnesium sulphate has been effectively used for treating patients with severe tetanus; recently, we also used the drug as a treatment for postanesthetic shivering.
