Physiologic possibilities of hemostasis in piglets that have experienced a technogenically induced episode of hypothermia in an aquatic environment

Adverse environmental factors affect the whole organism, including blood and hemostasis system. However, the role of physical parameters in the efficiency of the mechanisms that maintain the liquid state of blood has not been fully studied. The study focused on the evaluation of the parameters of the hemostasis system of piglets that were exposed to low temperatures as a result of an industrial accident. The experimental group of piglets consisted of 33 two-month-old piglets of the Large White breed, which underwent a short-term for 2.5 hours negative influence of cold water as a result of an anthropogenic breakdown. The established control group included 35 heads of physiologically mature, healthy 2-month-old piglets that had never experienced any adverse effects. Both groups were taken from the same farm. In 2-month-old piglets that experienced short-term exposure to low temperature, increased activity of platelet aggregation and coagulation hemostasis in combination with decreased fibrinolytic activity was found. The changes that occurred in them led to deterioration of blood movement in the vessels of the microcirculatory channel, slowing down metabolism and weakening the organism. Adverse hydroinfluence, apparently, includes a number of adaptive mechanisms, increasing the activity of the hemostasis system, contributing to the preparation of the organism for possible alteration of vessel walls to prevent blood loss.
