Various methods for insulating and wrapping hypothermic patients are used worldwide. The aim of this study was to compare the thermal insulating effects and comfort of bubble wrap ambulance blankets quilts and Hibler s method a lowcost method combining a plastic outer layer with an insulating layer. Methods Eight volunteers were dressed in moistened clothing exposed to a cold and windy environment then wrapped using one of the three different insulation methods in random order on three different days. They were rested quietly on their back for 60 minutes in a cold climatic chamber. Skin temperature rectal temperature oxygen consumption were measured and metabolic heat production was calculated. A questionnaire was used for a subjective evaluation of comfort thermal sensation and shivering. Results Skin temperature was significantly higher 15 minutes after wrapping using Hibler s method compared with wrapping with ambulance blankets quilts or bubble wrap. There were no differences in core temperature between the three insulating methods. The subjects reported more shivering they felt colder were more uncomfortable and had an increased heat production when using bubble wrap compared with the other two methods. Hibler s method was the volunteers preferred method for preventing hypothermia. Bubble wrap was the least effective insulating method and seemed to require significantly higher heat production to .
