Abstract:

AIM: To observe the effect of low dose dexmedetomidine combined with ulinastatin on immune function in patients with lung cancer. METHODS:A total of 120 patients with lung cancer scheduled to undergo operation were randomly divided into group A, B, C, D with 30 cases in each group. Before anesthesia induction, the patients in group B and group D received intravenous 0.3 μg·kg-1·h-1 dexmedetomidine after 0.3 μg/kg bolus. The patients in group C and group D received intravenous 200 000 U ulinastatin. The patients in group A received intravenous equal dose of saline. The levels of CD3+, CD4+, CD4+/CD8+ were determined before anesthesia (T0), 1 h after operation began (T1), 24 h (T2) after operation. The mean arterial pressure (MAP) and HR were also observed at T0, during tracheal intubation and extubation. The consumption of sevoflurane and remifentanil and the incident of bradycardia, hypotension and hypertension during operation were recorded. RESULTS:The levels of CD3+, CD4+ and CD4+/CD8+ of T1 and T2 were lower than those of T0 in group A, B and C (P<0.05). At T1 and T2, the levels of CD3+, CD4+ and CD4+/CD8+ in group B and group C were higher than those in group A (P<0.05), while those in group D were higher than those in other groups (P<0.05). The MAP and HR of tracheal intubation and extubation were higher than those of T0 in group A and group C (P<0.05). Compared with group A and group C, the MAP and HR of tracheal intubation and extubation were lower in group B and group D (P<0.05). The consumption of sevoflurane and remifentanil and the incident of hypertension were lower in group B and group D than those in group A and group C (P<0.05). CONCLUSION:Low dose dexmedetomidine combined with ulinastatin can improve perioperative immune function, inhibit stress response during tracheal intubation and extubation, and reduce the consumption of anesthetic drugs in patients with lung cancer.
