    Abstract:
    The influence of epidural anesthesia (CEA) on clinical manifestations, cortisole and adrenocorticotropic hormone (ACTH) level, central hemodynamic values during aorto-coronary bypass surgery (ACBS) in 56 patients aged 42-68 years with preserved functional capacity of the myocardium was studied. Catheterisation of the epidural space was carried out in the evening before the operation according to the standard method at the level of T4-T5 with the use of disposable epidural set. During the procedure before perfusion 2% solution of lidocaine 3.8 +/- 0.2 mg/kg was introduced in epidural space (taking into account test-dose) as a bolus in 3-4 motions. The dose of local anesthetics for infusion was selected separately for each individual case with due regard for hemodynamic values. During artificial circulation additionally local anesthetic was introduced as a bolus, the dose being 4.7 +/- 0.8 mg/kg. At the end of the operation morphine (0.061 +/- 0.001 mg/kg) was introduced. It was established that combined application of intravenous and epidural anesthesia represents highly effective method of anesthesia in aorto-coronary bypass surgery. According to clinical course data, cortisone and ACTH blood contents and hemodynamic parameters, EA provides adequate anesthesia, promotes stabilization of hemodynamic values and creates functionally more advantageous conditions for the myocardium in patients with CHD during aorto-coronary bypass operation. Anesthesiologic aid with the use of EA promotes reduction of intravenous anesthetics expenditure, earlier waking up of the patients in postoperative period and decrease in duration of postoperative artificial lung ventilation.
