General overcooling – develops with prolonged exposure to cold on the body
as a whole, proceeds in 4 phases.
Phase I - there is a feeling of cold, tremor, pallor of the skin, "goose
bumps". The body temperature is kept at +36 +37ºC.
Phase II - body temperature decreases by 1-2 degrees. At the same time,
there is pallor of the face, cyanosis, stiffness of movements in the joints, the

Phase III - the temperature drops to +34+27ºC. At the same time, pain
sensitivity decreases to its complete disappearance, bradycardia is noted,
apathy and drowsiness develop, muscle tremor turns into muscle rigor.
Phase IV - body temperature drops below +27ºC. At the same time, the
functions of the organs are gradually suspended, breathing, pulse, blood
pressure are barely detected, reflexes are absent, pain is not felt.In the future,
due to the suppression of the activity of the central nervous system, death
occurs.
Treatment: urgent compensation of heat loss is necessary, for which the
victim is placed in a warm room, wrapped up, intravenously injected with a
glucose solution heated to +40 ° C, you can warm the victim in a hot (t to
+40 ° C) bath. A solution of soda is injected, infusion therapy is performed,
and diuresis is stimulated.
