COMPARATIVE CHARACTERISTICS OF HEMODYNAMICS INDICES ALTERATIONS IN VARIOUS AGE GROUPS UNDER CONDITIONS OF EXTREMELY LOW TEMPERATURE

Keywords: cryotherapy, arterial pressure, absolute risk
Abstarct: Objective - to estimate the character of the alterations in peripheral hemodynamics and to compare the risk for their critical changes in general air cryotherapy in patients of various age with locomotor system pathology. Material and methods. 101 patients with painful syndrome caused by the pathology of locomotor system were examined. 25 patients aged 56 - 75 years old were enrolled in the first group, 76 patients aged 20 - 48 years old were enrolled in the second group. The status of peripheral hemodynamics (pulse rate, arterial pressure) was evaluated before the procedure and after it. Results. No significant deviations in hemodynamic indices studied were revealed in exposition to extremely low temperature. Systolic arterial pressure level was proved to be the most informative parameter; its alterations were mostly expressed in young patients in the first cryotherapeutic procedures. Critical deviations of hemodynamic parameters were revealed in elderly patients from the 5th to 15th procedures of cold cautery and their risk was statistically lowered till the 20th procedure. Conclusions. Elderly patients in the firs procedures of general air cryotherapy responded more slowly than young patients. In elderly patients maximal risk for hemodynamic critical deviations was registered on the 10th day and on the 15th day of the treatment course.
