Comparison of optimal doses of prophylactic dexmedetomidine for preventing post-operative shivering in patients undergoing elective laparoscopic cholecystectomy

Abstract

Postoperative shivering is an involuntary, oscillatory muscular activity during early recovery after anaesthesia. Postoperative shivering is a frequent complication of anaesthesia; it has been reported to range from 20 to 70% in general anaesthesia.Shivering is believed to increase oxygen consumption and increase the risk of hypoxemia; it might also increase postoperative complications.  dexmedetomidine might provide a simple pharmacological intervention to suppress shivering and improve comfort without producing respiratory compromise in patients.
