Postoperative Prevention of Acute Lung Injury

Abstract

Objective: to analyze the tactics of infusion therapy in old age group patients with generalized peritonitis and to search for ways of preventing acute lung injury in the early postoperative period. Subjects and methods. The adequacy of infusion therapy was analyzed in the treatment of 237 patients above 60 years of age who had generalized peritonitis. The parameters of central hemodynamics and aqueous sectors of an organism were studied by thermod-ilution and integral rheography of the body, radionuclide and thiosulfate tests. In 89 patients, normothermal infusion therapy was performed, by heating the transfused solutions to the body’s temperature. Results and discussion. When the volume of liquid is increased in the region under study, transthoracic impedance regularly decreases and it may be used as a predictor. In the early postoperative period, the scope of infusion therapy should be limited when the functional capacities of the cardiovascular system are diminished. Normothermal infusion therapy contributes to improvements of central hemodynamic parameters, microcirculation, and oxygen balance and reduces the number of pyoinflammatory complications. Conclusion. Normothermal infusion therapy diminishes a systemic inflammatory response and promotes the prevention of acute lung injury. Key words: central hemodynamics, normothermal infusion therapy, transthoracic impedance, acute lung injury.
