Abstract

Background: This study was designed to investigate the effects of leukocyte filtration of autologous salvaged blood on lung function, lung inflammatory reaction, and oxidative stress reaction in elderly patients undergoing lumbar spinal surgery. Materials and Methods: Sixty elderly patients undergoing lumbar spinal surgery were randomly divided into 2 groups: Leukocyte Filter group and Control group. Serum levels of inflammatory markers including white blood cell and polymorphonuclear count, neutrophil elastase, serum surfactant protein A, methane dicarboxylic aldehyde, superoxide dismutase, interleukin (IL)-6, IL-8, tumor necrosis factor-α, and respiratory function markers including dynamic respiratory system compliance, oxygenation index, and respiratory index were measured immediately before induction of anesthesia (T 0), immediately before blood transfusion (T 1), and 1 (T 2), 6 (T 3), and 12 hours (T 4) after end of blood transfusion. Results: The Leukocyte Filter group had higher dynamic respiratory system compliance at T 2, oxygenation index at T 2 and T 3, respiratory index and superoxide dismutase at T 2, T 3, and T 4 than those in the Control group (P<0.05). The Leukocyte Filter group had lower white blood cell, polymorphonuclear count, neutrophil elastase, serum surfactant protein A, methane dicarboxylic aldehyde, IL-6, IL-8, and tumor necrosis factor-α at T 2, T 3, and T 4 than those in the Control group (P<0.05). There were no significant differences in adverse reactions related specifically to blood transfusion or postoperative respiratory complications within 72 hours. Conclusions: Salvaged autologous blood leukocyte filtration can improve ventilation, promote gas exchange and oxygenation, and inhibit lung inflammatory and oxidative stress reactions in elderly patients undergoing lumbar spinal surgery.
