Objective To investigate the effect of leukocyte-depleted intraoperative salvaged blood on the erythrocyte immunity and systemic inflammatory response during the perioperative period in patients.Methods Twenty ASA Ⅰ or Ⅱ patients (aged 20-44 years and weighing 40-75 kg) requiring blood salvage during operation (with the estimated intraoperative blood loss of 15-20 ml/kg) were randomly divided into two groups (n =10 each):control group (group C) and leukocyte depletion group (group D).Anesthesia was induced with midazolam,fentanyl,propofol and vecuronium and maintained with isoflurane inhalation and intravenous infusion of propofol and remifentanil.The patients were mechanically ventilated after endotracheal intubation.Intraoperative blood salvage and reinfusion were performed in all the patients.In group D,the salvaged blood was filtered by a leukocyte depletion filter placed in the line of the reinfusion circuit.Blood samples were collected from the central vein before anesthesia (T1),at the end of surge
