Heat loss in an animal experimental model.

摘要: Abstract Heat loss leading to hypothermia is common during surgery, particularly when a body cavity exposed. To determine the principal site of heat we used flux transducers measure from skin and exposed abdominal seven pigs. was 74 +/- 15 W/m2, cavity, 350 122 W/m2 (p less than 0.002; ratio = 1:4.7). The area 0.52 0.06 m2, 0.04 0.006 m2 (ratio 13.6:1). For every 13.6 watts lost skin, 4.7 were cavity; i.e. accounted for 74% total loss. Therefore adequate insulation would reduce incidence hypothermia. Evaporation largest cavity. Evaporative losses could be minimised by enclosing bowel in plastic bag.
