舒芬太尼是芬太尼N-4位取代衍生物,镇痛效价是芬太尼的5~10倍,且起效快,心血管系统功能稳定,无组胺释放等。本研究拟比较舒芬太尼和芬太尼在不停跳冠脉搭桥术中麻醉效果,为临床合理用药提供参考。 相似文献

胶原酶溶盘术临床应用及进展 总被引:3,自引:0,他引:3
溶盘术(Disoolysis)曾称之为髓核溶解术(Nucleolysis)或化学溶核术(Chemonucleolysis),是应用胶原酶治疗腰椎间盘突出症的一种较有前途的非手术疗法,具有针对性强、疗效明显的优点,但其临床应用并未普及。本文就其临床应用及近期研究进展简述如下。 相似文献

目的 观察大鼠脊髓背角中核转录因子-Kb(NF-Kb)在慢性坐骨神经挤压性损伤(CCI)疼痛模型中表达的变化规律.方法 雄性SD大鼠48只,分为手术组和假手术组,每组24只,于CCI前1天、CCI后第1,4,7,14,21天各时间点测定机械痛阈及热痛阈后立即处死大鼠,每个时间点4只,取腰髓,采用Western blot方法测定NF-Kb的蛋白表达变化.结果 手术组大鼠术侧机械痛阈及热痛阔明显降低,脊髓背角中NF-Kb水平表达增加,明显高十对侧和假手术组;NF-KB蛋白水平于CCI后第1天开始增加,第7天达到高峰(P<0.01),于CCI后第21天仍维持于较高水平(P<0.05).结论 CCI致大鼠脊髓背角NF-Κb活化,参与神经病理性疼痛的调控过程.Abstract: Objective To investigate the expression of nuclear factor kappa B(NF-Κb)in the lumbar spinal cord in chronic constrictive injury(CCI)of the sciatic nerve.Methods Foay-eight male Sprague-Dawley rats were divided into 2 groups(n=24 in each).The operation group received CCI of the sciatic nerve and the sham-operation group received a sham operation as a control.Their mechanical and thermal nociceptive thresholds were assessed with paw withdrawal latency (PWL) using von Frey filaments and radiant heating.Four rats were sacrificed at each time point and segments of their lumbar spinal cords were examined using Western blotting.Results Mechanical and thermal stimulation thresholds were reduced significantly after the operation.Expression of NF-Κb protein increased significantly in the ipsilateral dorsal horn of the spine compared with the contralateral side and compared with the sham-operation group.NF-Κb protein expression began to increase on the 1 st day after the operation,reached a peak at the 7th day,and stayed high throughout the experiment.Conclusion NF-Κb in the dorsal horn of the spine may be involved in neuropathie pain after CCI. 相似文献

舒芬太尼预防全麻诱导期机体应激反应 总被引:5,自引:1,他引:5
将60例择期全麻手术患者随机分为Ⅰ、Ⅱ、Ⅲ组各20例,分别采用芬太尼、舒芬太尼和瑞芬太尼行麻醉诱导。于诱导前(T,基础值)、插管前即刻(T0)、插管后1min(T1)、3min(T2)、5rain(T3)记录收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)、心率(HR)、SpO2,并在各时点抽取静脉血,用高效液相色谱法测定血浆去甲肾上腺素(NE)和肾上腺素(E)水平。结果T0时三组MAP、HR和T时相比显著降低(P〈0.05),Ⅲ组下降幅度高于Ⅰ、Ⅱ组;Ⅲ组MAP、HR在各时点无显著差异;NE和E浓度除Ⅰ组在T1、T2时高于基础值(P〈0.05)外,其余各时点比较差异无统计学意义。提示舒芬太尼和瑞芬太尼抑制插管时应激反应的效果优于芬太尼;舒芬太尼更有利于血流动力学稳定。 相似文献
