Conditions

Outcome Measures

Primary Outcomes (1)

  • Post-operative core temperature greater than or equal to 36 degrees centigrade. This is a surrogate marker for complications such as reduced wound infection and reduced hospital stay that have been previously established by other research.

    15minutes to 2 hours approximately postoperatively in recovery room

Secondary Outcomes (2)

  • shivering

    up to 2h post op (time in recovery)

  • Core temperature

    From induction of anaesthesia to arrival in recovery

Study Arms (2)

warming mattress

EXPERIMENTAL

Patient warmed with electric mattress

Other: warming mattress

warming blanket

ACTIVE COMPARATOR

Forced air warming blanket

Other: warming blanket

Interventions

comparison of under patient warming mattress to forced air warming blankets in preventing peri-operative hypothermia

Also known as: Inditherm electric carbon polymer warming mattress
warming mattress
Also known as: forced-air warming blanket, Bair hugger
warming blanket
