Brief Summary
We propose a study in which we compare two intraoperative active warming devices for maintenance of normothermia in patients undergoing colorectal surgery. A novel underbody resistive warming mattress (VitaHeat) will be compared to the forced air warming blanket (3M Bair Hugger) that is currently used in our institution. Our hypothesis is that the underbody resistive warming mattress will be equally effective as forced air warming in maintaining normothermia in colorectal surgery.

Outcome Measures
Primary Outcomes (1)
The Primary Outcome Measure Will be the Percentage of Intraoperative Time the Participants Body Temperature is Above 36 Degrees Celcius.
The total percent of intraoperative time (time in the operating room) that the body temperature of the participant is above 36 degrees celcius measured using an esophageal temperature probe.
1 day
Secondary Outcomes (1)
Post Operative Temperature on Admission to Post Operative Care Unit (PACU)
Immediately after surgery
Study Arms (2)
Group 1: VitaHeat
ACTIVE COMPARATORPatients in group one will be warmed perioperatively with the VitaHeat mattress and IV fluid warmers once they are in the operating room.
Group 2: Bair Hugger
ACTIVE COMPARATORPatients in group two will be warmed perioperatively with the upper body bair hugger and IV fluid warmers once they are in the operating room.
Interventions
Patients will receive active warming via a heating mattress (VitaHEAT Medical) placed on the OR table with two thin sheets between the patient and the device; one covering the mattress and the other used as the draw sheet as usual practice. The device will be turned on 10 minutes prior to the patients' arrival to the operating room table. Patients' upper body will be covered with blankets. To increase skin surface contact with the mattress any blankets remaining under the patients' chest or head will be removed after intubation and replaced with a donut. IV fluid warmer initiated on arrival to the operating room. The operating room temperatures will be adjusted to 21°C.
Patients will receive standard forced air warming applied to the upper body and turned on after the patient is prepped and draped. These warmers will be placed directly in contact with the skin without any intervening insulation. IV fluid warmer initiated on arrival to the operating room. The operating room temperatures will be adjusted to 21°C.

Limitations and Caveats
The limitation of the results presented is that we did not reach full enrollment as referenced in the protocol because the sponsor terminated the study early.
