摘 要:目的观察单纯空腹血糖受损(IIFG)对体外循环(CPB)心内直视手术患者脑损伤的影响。方法随机选择择期行二尖瓣置换手术的空腹血糖正常(对照组)和IIFG患者(IIFG组)各25例,分别于麻醉诱导后(T1)、CPB开始后30min(T2)、停CPB时(T3)、停CPB后2h(T4)和术后第1天(T5)、2d(T6)6个时点抽取颈静脉血样,采用酶联免疫吸附试验测定血清神经元特异性烯醇化酶(NSE)、SIOOB和髓鞘碱性蛋白(MBP)的变化。结果两组NSE、S100B于停CPB时开始升高,停CPB后2h、术后第1天高于麻醉诱导后和CPB开始后30min水平。IIFG组在停CPB时、停CPB后2h、术后第1天3个时间点高于对照组[NSE:IIFG组依次为(9.12±0.94)、(13.87±2.55)、(12.67±3.38)μg/L,对照组依次为(7.21±0.81)、(9.11±1.20)、(7.47±1.22)μg/L(t=4.125、4.567、3.689,P=0.000、0.000、0.000);S100B:IIFG组依次为(2.09±0.33)、(4.21±0.79)、(2.36±0.54)μg/L,对照组依次为(1.23±0.25)、(2.39±0.48)、(1.22±0.24)μg/L(t=3.497、4.077、3.576,P=0.001、0.000、0.000)。MBP表达两组间差异无统计学意义。IIFG组术后2例、对照组1例出现谵妄,均恢复正常,两组未出现其他脑损伤的症状和体征。结论IIFG患者与空腹血糖正常者比较,CPB术后NSE和S100B水平相对较高,推测与IIFG患者出现更为严重的胰岛素抵抗和应激性高血糖有关。Objective To observe the effect of isolated - impaired fasting glucose (IIFG) on brain injury in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB). Methods Rheumatic heart valve disease patients with normal fasting blood glucose ( control group ; n = 25 ) and with IIFG ( IIFG group ; n = 25 ), who underwent elective mitral valve replacement, were randomly selected in this study. Preoperative, peroperative, and postoperative neuron specific enolase ( NSE ) , SIOOB and myelin basic prote (MBP) levels were compared. Results NSE and S100B levels were higher in IIFG group than in control group when the termination of CPB, 2 h after termination of CPB, and 24 h after surgery [ NSE : (9. 12±0.94), (13.87 e2.55), (12.67±3.38) μg/L vs. (7.21 ±0.81), (9. 11 ±1.20), (7.47± 1.22) μg/L; t=4.125, 4.567, 3.689; P=0.000, 0.000, 0.000; S100B: (2.09±0.33), (4.21± 0.79), (2.36±0.54) μg/L vs. (1.23 ±0.25), (2.39±0.48), (1.22±0.24) μg/L; t=3.497, 4. 077, 3. 576 ; P = 0. 001, 0. 000, 0. 000 ]. The expression of MBP was not statistically significant between the two groups. Delirium occurred in two cases of IIFG group and one case of control group. Signs and symptoms of other brain injuries were not detected in both groups. Conclusion Compared with the patients with normal fasting blood glucose, NSE and S100B levels were relatively higher in patients with IIFG after surgery under CPB.
