Abstract:
0 35 The patients had no endocrine or immune disease and received neither radio , chemo nor hormone therapy Anesthesia was induced with propofol, midazolam, fentanyl and succinylcholine After tracheal intubation the patients were mechanically ventilated Anesthesia was maintained with enflurane inhalation and intermittent intravenous boluses of midazolam, fentanyl and vecuronium After operation the patients were transferred to recovery room and PCA was started when the patients were wide awake VAS was maintained at 2 4 Venous blood samples were taken before surgery, before blood transfusion and on the 1st and 5th postoperative day for determination of T lymphocyte subsets and natural kill cell counts by flow cytometry (EPICS Elite USA) Results The two groups were comparable regard to sex, types of operation, intraoperative blood loss and volume of fluid infused The mean duration of operation of the two groups was (196?42) min The NK cell and CD + 3 and CD + 4 counts and CD + 4/CD + 8 ratio before transfusion were not significantly different from those before operation in both groups The NK cell, CD + 3 and CD + 4 counts and CD + 4/CD + 8 ratio decreased significantly on the 1st postoperative day in both groups but the decrease was more pronounced in group H On the 5th postoperative day the NK cell, CD + 3, CD + 4 counts and CD + 4/CD + 8 ratio returned to preoperative level in group A but remained low in group H Couclusions Perioperative homologous blood transfusion has serious and prolonged inhibitory effects on patient′s immune function In autologous blood transfusion group the changes are milder and the recovery is more rapid as compared with those in group H
