Abstract

Effects of dexmedetomidine (DEX) on perioperative stress response, inflammation and immune function in patients with different degrees of liver cirrhosis were investigated. A total of 94 patients with liver cirrhosis who were admitted to the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from December 2016 to November 2017 were included, and randomly divided into control and observation group (n=47). Patients in control group were given remifentanil for anesthesia, while patients in observation group were treated with remifentanil and for DEX anesthesia. Venous blood was collected immediately before induction of anesthesia (T1), 10 min (T2) after the beginning of surgery, immediately after surgery (T3) and 2 h after surgery (T4). Hemodynamic parameters, stress response factors, adverse reactions and levels of inflammatory cytokines and T lymphocyte subsets were compared between the two groups. The mean arterial pressure in both groups was lower at T2-T4 than that at T1 (p<0.05), and mean arterial pressure was lower in observation group than in control group (p<0.05). Visual analogue pain score (VAS) of observation group was significantly lower than that of control group at 6, 12 and 24 h after operation (p<0.05). There was no significant difference between the two groups in incidence of nausea, vomiting, hypoxemia and delayed awakening (p>0.05). Incidence of postoperative agitation in observation group was significantly lower than that in control group (p<0.05). The levels of CD3+, CD4+, and CD4+/CD8+ in both groups were significantly lower at T2-T4 than those at T1 (p<0.05). Levels of IL-10 and TNF-α in both groups were significantly higher at T2-T4 than those at T1, but levels of IL-2 and TNF-α were significantly lower in observation group than in control group (p<0.05). In conclusion, the use of DEX for anesthesia in patients with liver cirrhosis can improve hemodynamic stability, reduce stress response and reduce inflammation level without affecting immune function, which has important clinical significance.
