The aim: to use veloergometry test at patients of high anaeshtesiology-operative risk before traumatic operations for functional operability determination. Material and methods: Randomized prospective research with the double "blind" control has been performed at 95 patients of high risk (ASA>III), undergoing long and traumatic operations on thoracic and abdominal organs. Patients have divided into groups without complications and with complications (51 and 44 patients) which one day prior to operation have spent veloergometry test (VEMT). Average dynamic pressure (ADP), the general peripheral resistance of vessels (GPRV), a core index (Cl); arterio-venous (a-v) difference on oxygen, oxygen delivery to tissues, consumption of oxygen and coefficients extraction oxygen in tissues; energy consumption have been investigated. Statistics has been done by nonparametric methods. Results. In response to veloergometry test in both groups growth of Cl at the expense of a tachycardia and GPRV fall which in complication group remains above norm is noted. In group without complications coefficients extraction oxygen in tissues were normalised, a-v difference on 02 became above norm, in other group — coefficients extraction oxygen in tissues and a-v difference on 02 began to exceed norm, and oxygen consumption has grown almost in 2 times. After VEMT a-v a difference on О and oxygen consumption were essentially above in group with complications. Under the influence of VEMT markecT stabilization of function of vegetative nervous systems (VNS). The number of complications made 39: intraoperation cardiovascular — 23, postoperative respiratory — 16. Clinically important connection (p=0,069) of perioperative complications with growth a-v differences on oxygen and a power interchanging have been received. Conclusion. Thus, the oxygen-energy exchange and the vegetative status can be referred to clinical functional operability determination.

It is lead randomized prospective research with the double "blind" control over 228 patients of high risk (ASA>III), undergone long and traumatic to operations on bodies of a breast and a stomach. Have excluded from research 133 patients. The staying 95 patients have divided into groups without complications and with complications (accordingly 51 and 44 patients) which one day prior to operation have carried out exercise testing. Investigated: ADP, CPRV, SI, a arterio-ve-nous difference on oxygen, delivery of oxygen to fabrics, consumption of oxygen in fabrics, factor extraction oxygen in tissue, a power exchange. In reply to exercise testing in both groups growth of SI is marked due to a tachycardia and falling CPRV which in group of complication remained above norm. In group without complications it was normalized FEO, 6-v the difference on О became higher than norm, in other group — FEO and б-v a difference on 02 began to exceed norm, and consumption of oxygen has grown almost in 2 times. After exercise testing б-v a difference on 02 and consumption of oxygen were essentially higher in group with complications. The total of complications made — 53, respiratory — 16, inflammatory — 23 and purulent — septic complications — 14. Clinically important connection (p=0,06939) perioperative complications with growth a-v differences on oxygen and a power exchange is received
