Importance of hypothermia in multiple trauma patients

Multiple trauma patients frequently demonstrate a hypothermic core temperature, defined as a temperature below 35A degrees C, already at admission in the emergency room. As a drop of the core temperature below 34A degrees C has been shown to be associated with a significant increase in post-traumatic complications, this limit is considered to be critical in these patients. Multiple trauma patients with hypothermia demonstrate a markedly increased mortality rate compared to normothermic patients with the same injury severity. Therefore effective rewarming measures are essential for adequate bleeding control and successful resuscitation. If and to what extent the induction of controlled hypothermia in the early phase of treatment on the intensive care unit after resuscitation and operative bleeding control can contribute to an improved post-traumatic outcome, has to be clarified in further experimental and clinical studies.
