[First experience of using cardiorespiratory load testing to assess the functional status of the patient in the pre-operational period].

: In anesthetics practice exist different scales and indexes, _through which the evaluation functional condition of the patient. The disadvantage of these scales and tests are subjective evaluation as a condition of the patient, who is able to re-evaluate their functionality and anaesthesiologist, co-tory may underestimate the presence of comorbidities and patient complications in the postoperative period. The method of improvement of objective assessment of the patient's functional reserves, of a cardiorespiratory exercise testing is given. The methodology of testing in 18 patients, who were later performed surgery on the abdominal organs. The definition-of anaerobic threshold was conducted using V-slope method. In all cases was reached and was 11,1 (10,1; 12) mI/kg/min. Maximum oxygen consumption was 15,7 (15,2; 18,3) ml/kg/min. The results show the possibility of using the selected duct la research to predict possible complications and post-operative period.
