摘要:

目的 探讨不同剂量舒芬太尼对心脏瓣膜置换术患者围术期血浆炎性细胞因子和丙二醛(malonic dialdehyde, MDA) 的影响。 方法 30 例心脏瓣膜置换术患者, 随机分为 3组即S1组 (舒芬太尼总量 3 μg/kg) , S2组 (舒芬太尼总量 5 μg/kg)和 S3组 (舒芬太尼总量 10 μg/kg)。分别于麻醉前 (T0)、 开胸后 5 min (T1) 、 阻断后 30 min (T2) 、 开主动脉后 2h (T3) 和术后 24h(T4) 各时间点测定动脉血中肿瘤坏死因子 α (TNF-α) , 白细胞介素-6 (IL-6) 以及血浆 MDA 浓度, 并记录 3 组患者在 ICU 的滞留时间和拔管时间。 结果 与麻醉前 (T0) 比较, 3 组 TNF-α (ng/L)、IL-6(ng/L)和MDA(mmol/L)在体外循环 (cardiopul monary bypass,CPB) 后明显升高 (P<0.01 或P<0.05),S2组在 T2 (TNF-α15.7±4.1、 IL-6 116.5±18.2和MDA 8.5±0.8)、T3(TNF-α22.8±3.6、IL-6 158.9±13.7 和 MDA 10.2±1.3)时均明显低于S1组T2(TNF-α20.3±4.5、 IL-6 141.8±21.3 和 MDA 10.6±0.9)和T3(TNF-α28.1±3.7、 IL-6 175.6±15.1 和 MDA 12.5±1.4)时(P<0.05),S3组在T2(TNF-α14.4±3.2、 IL-6 115.3±19.8 和 MDA 8.3±0.8)、T3(TNF-α21.0± 3.7、 IL-6 156.7±14.3 和MDA 9.8±1.4)时均明显低于S1组(P<0.05),但S2、S3组比较差异无统计学意义。S3组患者 ICU 滞留时间(3.5±0.5)d 和术后拔管时间 (29.3±3.0)h 较 S1(2.2±0.5)d,(18.2±2.5)h和 S2组 (2.4±0.4)d,(19.3±2.8)h 明显延长(P<0.05)。结论 CPB 可促发促炎细胞因子及氧自由基的释放,较大剂量舒芬太尼能抑制心脏手术所致的全身性炎性反应, 减少氧自由基的产生,从而减轻再灌注损伤,但达到一定剂量后这种效应并不存在剂量依赖性,且延长患者在 ICU 的滞留时间。

Abstract:

Objective To investigate the effect of sufentanil on inflammatory cytokines and MDA of plasma in valve replacement surgery during cardiopulmonary bypass(CPB) . Methods Thirty adult patients undergoing valve replacement with cardiopulmonary bypass were randomly divided into 3 groups: GroupS1 (sulfentanil 3 μg/kg) ,GroupS2 (sulfentanil 5 μg/kg) , GroupS3 (sulfentanil 10 μg/kg) . Blood samples were taken before anesthesia(T1),5 min after opening the thorax(T2),30 min after aortic clamping (T3),2 h after aortic declamping (T4) ,and 24 h(T5)after the operation for determination of plasma levels of tumornecrosis factor (TNF-α) ,interteukin-6(IL-6)and MDA. The stage of ICU and the extubation time were recorded. Results Levels of TNF-α,IL-6 and MDA after the CPB in the 3 groups were significantly higher compared with T0 (P<0.01) . TNF-α (ng/L) ,IL-6 (ng/L)and MDA(mmol/L) levels at T2, T3 were significantly lower in GroupS2(atT2: TNF-α15.7±4.1, IL-6 116.5±18.2 and MDA 8.5±0.8,atT3:TNF-α22.8±3.6, IL-6 158.9±13.7 and MDA 10.2±1.3) than those in GroupS1(at T2: TNF-α 20.3±4.5、 IL-6 141.8±21.3 and MDA 10.6±0.9,at T3: TNF-α28.1±3.7、 IL-6 175.6±15.1 and MDA 12.5±1.4). TNF-α, IL-6 and MDA levels at T2,T3 were significantly lower in GroupS3 (at T2: TNF-α15.7±4.1、 IL-6 116.5±18.2 and MDA 8.5±0.8, at T3: TNF-α22.8±3.6、 IL-6 158.9±13.7 and MDA 10.2±1.3) than those in GroupS1. But levels of TNF-α, IL-6 and MDA in GroupS2 were not significantly different compared with those in GroupS3. The duration of stay in ICU and time of endotracheal extubation were significantly longer in patients of GroupS3(3.5±0.5)d, (29.3±3.0)h than those of GroupS1(2.2±0.5)d,(18.2±2.5)h andS2 (2.4±0.4)d,(19.3±2.8)h(P<0.05). Conclusion CPB leads to a proinflammatory response,as well as oxygen free radicals release. Larger dose sufentanil seemed to be effective in reducing CPB-induced inflammatory response and ischemic reperfusion injury,but the effect was not dependent on dose while sufentanil dose reaching some value,at the same time the duration of stay in ICU and time of endotracheal extubation were longer.
