[Central hemodynamics and hormonal homeostasis during surgical stress in young patients with different levels of physical preparation].

Twenty-two patients, aged 16 to 35 years who were to be operated on for varicocele have been examined. It has been established that the degree of shifts in hormonal homeostasis and central hemodynamics depends on the baseline level of physical training. Analysis of central hemodynamic response to operation stress has shown that the prognosis of favourable operation stress tolerance was observed in well trained patients or in those poorly trained without hyperkinetic hemodynamic reaction 1 day before surgery. The above data make it possible to predict the nature of reactions in response to the operation stress by the level of circulation function activation 1 day before surgery.
