Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Prewarming group
Prewarmed for 20 minutes prior to OR using 3M Bair Paws System, a forced air warming blanket. This warming blanket was then used intraoperatively throughout the case.
3M Bair Paws Warming System
20 minutes of prewarming immediately pre-operatively using 3M Bair Paws warming system
Control group
Patients received standard care, which is no active prewarming prior to OR. A full body, forced air warming blanket (same as treatment group) was used intraoperatively throughout the case.
No interventions assigned to this group
