[A new method of antibiotic prophylaxis in liver surgery]

Ninety patients with focal affections of the liver were followed up. The patients were operated on the liver and treated therapeutically and prophylactically by means of the target-aimed release of antibiotics in erythrocyte ghosts. The antibiotics used were gentamicin and aztreonam. The results of the clinico-laboratory examinations showed that the target-aimed transport of the antibiotics in erythrocyte ghosts provided a 9-fold increase of the antibiotic level in bile and its 2-fold increase in the liver tissue. The time of the drug retention in the body fluids and tissues increased 2 times as compared to that provided by the routine treatment. The incidence of the postoperative purulent complications decreased 3 times. Such an effect is likely due not only to the target-aimed release of the drugs but also to the possible immunomodulating action of the prophylactic procedure used for preventing the complications that prevented as well the development of severe postoperative immune deficiency. Aztreonam proved to be more efficient in the prophylaxis of the postoperative complications.
