详细描述
The investigators propose a single-center, assessor-Blinded, multiple crossover randomized trial to determine the efficacy of four warming devices and five blankets. The investigators will measure cutaneous heat loss/ gain using thermal flux transducers in unanesthetized volunteers.
American Society of Anesthesiologists (ASA) physical status 1 and 2 adults with body-mass index 20-33 kg/m2 will be included in this study. Volunteers will be excluded if they have serious skin lesions, history of allergy or skin sensitivity to tape or adhesive materials, serious vascular disease in the arms including Raynaud's Syndrome, or a history of recent fever or infection.
20 volunteers will be randomized to one of 5 different sequence groups: 1. Mistral Air, Blower MA1200-PM. plus the Adult Blanket plus, MA2220, 2. Mistral Air, Blower MA1200-PM plus the Premium Adult Blanket, 3320, 3. 3M, Bair Hugger, Blower 775 plus Blanket full body, 30000, 4. Smiths Medical, Blower L1-CW-100V, plus Blanket full body SWU-2001, 5. Care Essential, Cocoon, Blower CWS5000 plus Blanket Full Body blanket (CLM0101).
