[The characteristics of epidural anesthesia in operations on the aorta and vessels of the lower extremities].

Under study were the parameters of microcirculation in 84 patients operated on the vessels in the aorto-ilio-femoral zone, in 33 patients operated on the vessels in the femoro-popliteal zone. In all of them epidural anesthesia was used. In 25 patients operations on the aorta and main vessels were fulfilled under conditions of epidural anesthesia with catheterization of the epidural space at two levels. The dynamics of microcirculation parameters allows to state that the epidural anesthesia with catheterization of the epidural space at two levels is more rational for patients in operations on the vessels in the aorto-ilio-femoral zone since it gives adequate anesthesia during operation and better tissue blood flow in lower extremities.
