Abstract:
Extreme temperatures can lead to exceeding the capacities of the thermoregutation mechanism, wich imposes an overload of the circulatory system several times and implicitly to the high risk of dysfunctions in the hemostasis and blood coagulation system. Blood coagulation have an important role in limiting blood loss and repairing vascular damage. If the temperatures rises to the upper level the impact on body functions are very strong and becomes critical for survival. Hyperhermia lasting 6, 120, 180 min. leads to a visible change in the amount of fibrinogen and the number of platelets, which is manifested by their increase. Growing the level of fibrinogen and the number of platelets in the blood under the action of hyperthermia of different duration leads to an increase in blood coagulability, by reducing the coagulation time.
