Abstract:
Objective To compare the effects of mild hypothermia or normothermia on inflammatory cytokines (IL-2 and IL-10) in elderly patients undergoing surgery for rectal cancer, and determine whether the elevation of IL-2 and IL-10 levels and early postoperative cognitive dysfunction has the relevant. Methods Forty ASA classification Ⅰ or Ⅱ patients aged 65-83 yr undergoing surgery for rectal cancer were randomly divided into 2 groups (n=20 each):normal body temperature group (GroupⅠ) and mild hypothermia group (GroupⅡ) . The venous blood samples were taken at 3 points which were at 1 h before anesthesia (T1), the end of operation (T2) and the 24h after operation (T3) to measure the levels of plasma IL-2 and IL-10. The cognitive function test (MMSE) were performed at one day before operation (N1), one day after operation (N2) and 3th days after operation (N3) . Results The level of plasma IL-2 was significantly lower in the GroupⅡthan that in the GroupⅠat T2 and T3 ( < 0.01), and those was significantly lower at T3 than that at T2 ( <0.01) . The level of plasma IL-10 was significantly higher in the GroupⅡat T3 than that at T1 and T2 ( <0.01) . To compare with N1, the score of both groups were decreased at N2 ( <0.05), and it was lower in GroupⅡthan that in GroupⅠ( <0.05), with a significant difference. The score of both groups were increased significantly at N3 (<0.05), and there was significant difference with N2 ( <0.05);Positive correlation was found between IL-2 at T2 and T3 and the score of MMSE in the GroupⅡat N2 ( =0.459, <0.01) ( =0.550, <0.01) . Conclusion Positive correlations were found between the elevation of IL-2 levels under mild hypothermia and the decline of postoperative early cognitive function in elderly undergoing rectal cancer surgery.
