[Effects of epidural blockade on the indices of central hemodynamics in operations of the aortofemoral bifurcation shunting].

The aim of the investigation was to study the mechanisms of arterial hypotension in the development of epidural blockade and to work out differentiated correction of disorders of the central hemodynamics at the stage of surgical intervention depending on the initial state of the cardio-vascular system. Three main types of the preoperative state of the central hemodynamics indices were defined in patients after operation on the abdominal part of the aorta. To prevent hemodynamic shifts in response to epidural anesthesia it is necessary to carry on differential therapy depending on the type of the preoperative state of hemodynamics including dosed infusion therapy, and for the development of syndrome of low cardiac output an inotropic support with Dobutamin is to be used.
