[Peridural anesthesia during mitral commissurotomy on patients in the late stages of the disease].

Peridural anesthesia in T1--T6 regions was used together with general anesthesia in closed mitral commisurotomy in 40 patients with the disease in stages 4 and 5. The study was aimed at the evaluation of the effect of peridural anesthesia upon hemodynamics, gas exchange, adrenal cortex function, energy exchange in the myocardium and the evaluation of its expediency for these patients. The authors studied hemodynamic alterations (HR, AP, CVP, MV, CBV etc.), changes of acid-base equilibrium and in the blood gases, concentration of summary 11-oxycorticosteroids in the blood plasma and of creatinophosphate in the myocardium left auricle. On the grounds of these studies the authors have come to some practically important conlusions.
