Abstract

This study investigated the effects of different anesthesia and analgesia methods on immune function and serum tumor marker levels of critically ill patients undergoing tumor resection surgery. Seventy-six critically ill patients with indications for tumor resection surgery were selected in The Second Affiliated Hospital of Zhengzhou University from September 2015 to August 2016. The patients were randomly divided into a control and an observation group (38 patients each). The patients in the control group were treated with general anesthesia and postoperative intravenous analgesia, while the patients in the observation group were treated with general anesthesia and epidural anesthesia and postoperative epidural analgesia. Venous blood samples were collected at 30 min before anesthesia (T1), 2 h after the beginning of the surgery (T2), immediately after surgery (T3), 24 h after surgery (T4) and 72 h after surgery (T5). The viable cell percentage of T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) and natural killer (NK) cells were measured by flow cytometry. The levels of carcinoembryonic antigen, sugar chain antigen 199, sugar chain antigen 125, neuron specific enolase and cytokeratin 19 were detected by electrochemiluminescence at 24 h before and after operation. Our results showed the levels of CD3+, CD4+ and CD4+/CD8+ in the control group at T3-T5 were significantly lower than those at T1 (p<0.05). The CD3+ level in observation group at T3 was also significantly lower than the level at T1 (p<0.05), but it increased at T4 and T5 and showed no significant difference compared with the initial level (p>0.05). The levels of CD4+ and CD4+/CD8+ in the observation group were significantly higher than those in the control group at T2-T5 (p<0.05). And, the levels of CD3+ and CD4+ were significantly higher than those in the control group at T4 (p<0.05). The level of CD4+/CD8+ was significantly higher than that in the control group at T5 (p<0.05). No significant differences were found in the levels of CD8+ and NK cells between the 2 groups at any of the time‑points (p>0.05). No significant differences were found either in any of the tested tumor markers in either group after 24 h. Even without differences on the tumor marker levels, these results suggest that general anesthesia combined with epidural anesthesia and analgesia produces milder deleterious effects on the immune function of perioperative critically ill patients than general anesthesia combined with intravenous analgesia.
