Hydrocortisone reduces postoperative shivering following day care knee arthroscopy.

Purpose: Postoperative shivering is commonly observed in patients after general anesthesia. A double-blind randomized controlled trial was conducted in patients undergoing day care knee arthroscopy to test the hypothesis that a single intraoperative dose of hydrocortisone would prevent or attenuate postoperative shivering.

Methods: One hundred and twenty patients were given a nitrous oxide-isoflurane-remifentanil anesthetic.
