The use of tramadol hydrochloride in the treatment of post-anesthetic shivering.

ABSTRACT

Tramadol at the dosage of 1 mg per kg body weight was given intravenously to 110 adult patients who developed postoperative shivering. All patients were cured of the shivering after 45 seconds to 6 minutes. Seventy-four per cent stopped within 2 minutes after the injection. There were five patients who had recurrence of shivering after 10 to 30 minutes and this was easily stopped by another dosage of the drug. There were very few minor side effects and they required no medical treatment.
