Myocardial contractile function and acid-base balance in trauma patients treated by the Ilizarov method under peridural anesthesia

Peridural anesthesia as a method of anesthesia continues to attract attention because it has no pathological effect on the functions of vital organs, except for rare cases of severe hypotension. There are controversial opinions regarding the effect of peridural anesthesia on cardiodynamics. Some authors believe that peridural blockade reduces the tonic action of sympathetic nerves, resulting in bradycardia, decreased myocardial contractile function with depressed cardiovascular system. Others argue that during peridural anesthesia there are no significant changes in intracardiac hemodynamics. According to others, moderate concentrations of anesthetic penetrating into the circulating blood increase cardiac output and slightly increase BP.
