Outcome Measures

Primary Outcomes (1)

  • Patient Temperature at the Time of Incision as Measured by SpotOn (3M) Temperature Monitoring System..

    Temporal artery temperature readings (in degrees celsius) will be obtained at the time of incision and every 30 minutes while in the OR.

    The treatment period starts with the patient consenting to the study and application of preoperative forced-air warming device and ends when the patient leaves the PACU (average 4-8 hours following enrollment).

Secondary Outcomes (7)

  • Patient Temperature Prior to Entering OR as Measured by SpotOn (3M) Temperature Monitoring System.

    The treatment period starts with the patient consenting to the study and application of preoperative forced-air warming device and ends when the patient leaves the PACU (average 4-8 hours following enrollment).

  • Patient Temperature 30 Minutes Following Incision as Measured by SpotOn (3M) Temperature Monitoring System.

    The treatment period starts with the patient consenting to the study and application of preoperative forced-air warming device and ends when the patient leaves the PACU (average 4-8 hours following enrollment).

  • Patient Temperature on Arrival to Recovery Room as Measured by SpotOn (3M) Temperature Monitoring System.

    The treatment period starts with the patient consenting to the study and application of preoperative forced-air warming device and ends when the patient leaves the PACU (average 4-8 hours following enrollment).

  • Incidence of Postoperative Shivering in Recovery Room.

    The treatment period starts with the patient consenting to the study and application of preoperative forced-air warming device and ends when the patient leaves the PACU (average 4-8 hours following enrollment).

  • Intraoperative Blood Loss.

    The treatment period starts with the patient consenting to the study and application of preoperative forced-air warming device and ends when the patient leaves the PACU (average 4-8 hours following enrollment).

  • +2 more secondary outcomes
