The effect of hysterectomy was studied on natural killer (NK) cell activity, the distribution of lymphocyte subpopulations, and the endocrine stress response in 16 patients allocated to receive extradural analgesia S5-T4 (group I) or neuroleptanaesthesia (NLA) (group II). In group II a significant decrease in NK cell activity was found after operation for at least 3 days, while surgery during extradural analgesia did not induce significant changes. The impaired NK cell activity was accompanied by leucocytosis and lymphopenia affecting the T-lymphocytes (OKT3+ and OKT4+), the B-lymphocytes (B1+) and NK cells (Leu 11+). Compared with group II, extradural analgesia significantly reduced the cortisol and noradrenaline response to surgery, while the adrenaline response in both groups was abolished. The results suggest that the decrease in NK cell activity and alterations in lymphocyte subsets induced by surgery and general anaesthesia can be prevented to a certain degree by extradural analgesia.

Blood leucocyte-counts, cortisol, and glucose were measured in twelve healthy premenopausal women undergoing elective abdominal hysterectomy during either general anaesthesia (six women) or epidural analgesia (T4 to S5) (six women). Surgery during general anaesthesia caused significant lymphopenia 6 and 9 h after skin incision and significantly increased granulocyte-counts 6, 9, and 24 h after skin incision. Epidural analgesia prevented lymphopenia and reduced granulocytosis to about 40% of that seen in the group receiving general anaesthesia. The normal increase in plasma glucose and cortisol during and after surgery was abolished by epidural analgesia. These results indicate that neurogenic stimuli from the surgical area, probably through their influence on adrenal hormones (cortisol and adrenaline), are the main mediators of postoperative lymphopenia and are partly responsible for postoperative granulocytosis. Inhibition of the endocrine-metabolic response to surgery may prevent postoperative immunodepression.

To evaluate the effects of exploratory laparotomy on cellular and biochemical parameters of blood and peritoneal fluid, an experiment was conducted using 10 Iranian cross-bred male goats. Approximately 10 ml of blood and 1-1.5 ml of peritoneal fluid were collected from all animals prior to operation for estimation of control values. Exploratory laparotomy was performed under local analgesia. Blood and peritoneal fluid samples were collected at 24, 48, 72 and 96 h after exploratory laparotomy. The results revealed that after exploratory laparotomy, the number of white blood cells and the percentage and absolute number of neutrophils and band neutrophils significantly increased (P < 0.05). However, the percentage of lymphocytes decreased significantly (P < 0.05). The concentrations of blood urea nitrogen significantly increased (P < 0.05). Furthermore, following the operation, the percentage and absolute number of neutrophils in the peritoneal fluid significantly increased (P < 0.05). In contrast, the percentage of lymphocytes in the peritoneal fluid decreased significantly (P < 0.05). The concentration of protein in the peritoneal fluid increased significantly (P < 0.05).

We investigated whether perioperative extensive epidural block (C3-L) affects postoperative immune response in patients undergoing radical esophagectomy. Patients undergoing radical esophagectomy were randomly assigned to either general anesthesia with continuous epidural infusion via 2 epidural catheters that was continued for postoperative analgesia (group E, n = 15) or intraoperative general anesthesia and postoperative IV morphine analgesia (group G, n = 15). Plasma levels of stress hormones, cytokines, C-reactive protein (CRP), leukocyte counts, and distribution of lymphocyte subsets were assessed before and after surgery and on postoperative days (PODs) 1 and 3. In comparison with group E, significant increases in plasma epinephrine level at the end of surgery (P < 0.05) and norepinephrine level at the end of surgery (P < 0.01) and on POD1 (P < 0.01) and POD3 (P < 0.01) and significant decrease in cluster of differentiation (CD4/CD8 ratio) at the end of surgery (P < 0.05) were observed in group G. However, there were no significant differences in other variables between groups. In both groups, plasma cortisol, adrenocorticotropic hormone, interleukin (IL)-1beta, IL-6, IL-10, and CRP levels were increased after surgery (each group P < 0.01) and IL-1beta, IL-6, IL-10, and CRP were still increased on POD1 and POD3 (each change, each group P < 0.01). Leukocyte counts were increased on POD1 (each group P < 0.05) and POD3 (each group P < 0.01). The proportion of lymphocytes decreased from the end of surgery to POD3 (each group P < 0.01). The proportion of B cells was increased on POD1 (each group P < 0.01); that of natural killer cells was decreased at POD1 and POD3 (each group P < 0.01). We conclude that tissue damage and inflammation apparently overcome the effects of extensive epidural block on stress response and immune function in radical esophagectomy.
