Percentage of cases receving general anesthesia that had at least one core temperature documented intraoperatively.
General anesthesia causes vasodilation thus redistributing body heat from the core to peripheries. This redistribution can cause hypothermia. Core temperatures outside the normal range pose significant risks to patients. Pediatric patients are more likely to develop perioperative hypothermia due to a high surface area to weight ratio and inability to regulate their own temperature.1 Published research has correlated impaired wound healing, adverse cardiac events, altered drug metabolism, and coagulopathies with unplanned perioperative hypothermia. These adverse outcomes resulted in prolonged hospital stays and increased healthcare expenditures. The mortality rate is almost 20% higher only monitoring skin temperature rather than a core temperature for those who experience malignant hyperthermia during surgery.2 Core temperature measurements are less variable than skin temperature measurements and more accurately represent body temperature.3-5
All surgical patients receiving general anesthesia
*Cases where 'Measure End Time' precedes 'Measure Start Time' will be excluded and marked 'invalid'
