  • Hypothermia :stop cold insufflating !Halte à l’insufflation froide ! Claude Hébette, Hôpital de Moûtiers 1971 - 1998 Véronique Legrand, Annecy Lucien Cadoz, FIPS FIPS 15th World Congress, Tignes, april 2005
  • To be read with comments pages.A lire avec pages de commentaires. Jean Chièze FIPS 15th World Congress, Tignes, april 2005
  • Vital risk of hypothermia = heart inefficiency FIPS 15th World Congress, Tignes, april 2005 View slide
  • Heart contraction chemical conditionsand physical conditions : minimal temperature. FIPS 15th World Congress, Tignes, april 2005 View slide
  • During the rescue,riskof passing below the threshold cardiac arrestor ventricular fibrillation drugs ineffective defibrillation ineffective FIPS 15th World Congress, Tignes, april 2005
  • Why ? 1 Cold blood shell  coreHow ?• abrupt shifts of postures• sometimes external rewarming FIPS 15th World Congress, Tignes, april 2005
  • hypothermicnormal FIPS 15th World Congress, Tignes, april 2005
  • cautionsDMTM Chamonix • winch pulling up • stretcher carrying horizontally FIPS 15th World Congress, Tignes, april 2005
  • cautions• external rewarming may be dangerous• internal rewarming is safer FIPS 15th World Congress, Tignes, april 2005
  • cautions• external rewarming may be dangerous• internal rewarming is safer FIPS 15th World Congress, Tignes, april 2005
  • Why ? (contind.)2 Heat loss • through the skin • but also through the airway = caloric haemorrhage (Conn) 70 m² FIPS 15th World Congress, Tignes, april 2005
  • cautions• blankets, caps...• but also « caloric tourniquet » FIPS 15th World Congress, Tignes, april 2005
  • Why ? (contind.) 3 Inhalation of cold air or oxygen  lungs , near heart especially in case of intubation FIPS 15th World Congress, Tignes, april 2005
  • If the first responder thinksrespiratory assistance is necessary cautiongas insufflated must be warmed FIPS 15th World Congress, Tignes, april 2005
  • The rescuer must knowif the core temperatureis near the critical level (28-30°C)A special thermometer is indispensable FIPS 15th World Congress, Tignes, april 2005
  • How to rewarm air or oxygen ? • soda lime + CO2 • electricity • cooking pot + water ! • « solid oxygen » • hydrogen + oxygen ( + catalyst) FIPS 15th World Congress, Tignes, april 2005
  • How rewarm the gas ? Soda lime Ca(OH)2 + CO2  CaCO2 + H2O 2NaOH + CO2  Na2CO3+ H2O + FIPS 15th World Congress, Tignes, april 2005
