Dying of cold: Hypothermia in trauma victims
ScienceDaily (July 27, 2012) Hypothermia in trauma victims is a serious complication and is associated with an increased risk of dying. A new study published in BioMed Central’s open access journal Critical Care has found that the key risk factor was severity of injury. However, environmental conditions and medical care, such as the temperature of the ambulance or temperature of any fluids administered intravenously, also increased risk.
A multicentre study, carried out by the emergency medical services of eight hospitals across France, looked at the injuries, care and outcomes for all adult trauma victims, over a three year period, who received prehospital care and were transported to hospital in an ambulance. Body temperature was continuously measured using a infrared tympanic thermometer and hypothermia was defined as below 35C.
While external air and ground temperatures seemed to have tiny effect on risk of hypothermia, the study found that infusion fluid temperature and the temperature inside the ambulances were both significant risk factors.
Dr Lapostolle continued, “The temperature of infused fluid for 75% of our patients was below 21C and usually at ambient air temperature. We suggest that, to reduce the incidence of hypothermia, the temperature of infusion fluids need to be controlled, and that a small a volume as possible is used. Temperature of infusion fluids can be easily and rapidly measured in prehospital settings. We also recommend that ambulances should be heated and that as much as possible the patient should remain clothed, because attempting to warm the patients did not compensate for the effect of them being undressed even if it can make examination more difficult.”
