Background: Humans maintain constant body temperature within a wide range of changes in external
environment. Core body temperature is maintained within narrow range; Enzyme systems in the body have narrow
temperature ranges in which they function optimally for caring out different activities in the body as metabolism,
conduction of nervous function and skeletal muscle contraction. Perioperative hypothermia is one of the major
problems during surgery that can affect operated patients. It has been shown by different researchers that
Perioperative hypothermia will result in to various adverse events such as myocardial ischemia, coagulopathy,
delayed awakening and wound infections
