Abstract

BackgroundSurgical stress can induce postoperative systemic leukocytic alterations, including leukocytosis, neutrophilia, or lymphopenia. The present study investigated whether the anesthetic technique could affect the leukocytic alterations, including neutrophil-to-lymphocyte (N/L) ratio, after gynecologic laparoscopy.MethodsForty patients scheduled for laparoscopy-assisted vaginal hysterectomy were randomly assigned into two groups: PR group, which received total intravenous anesthesia with propofol and remifentanil, and S group, which received inhalational anesthesia with sevoflurane. Differential counts of leukocytes with N/L ratio of peripheral blood were obtained just before induction (T1), at the end of surgery (T2), 2 hours after surgery (T3), and 24 hours (T4) after surgery.ResultsSignificant increase in total leukocytic count, neutrophil count, and N/L ratio, and decrease in lymphocytic count were observed at all time points after surgery in both groups. N/L ratio was significantly lower in group PR compared with group S at T3. The increase of N/L ratio in contrast to the value at T1 was significantly lower at T2 and T3 in group PR compared with that of group S.ConclusionTotal intravenous anesthesia with propofol and remifentanil resulted in transient but salient leukocytic alterations in the peripheral blood in terms of N/L ratio compared with inhalational anesthesia with sevoflurane in laparoscopy-assisted vaginal hysterectomy.
