Use exercise testing for an estimation of a oxygen-power exchange at patients of high anesthesiology-operational risk

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-venous 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, б-v the difference on О2 became higher than norm, in other group - FEO and б-v a difference on О2 began to exceed norm, and consumption of oxygen has grown almost in 2 times. After exercise testing б-v a difference on О2 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
