目的比较超声引导下股神经阻滞和髂筋膜阻滞在老年患者全髋关节置换术中的麻醉效果。方法选择徐州仁慈医院2020年1—12月择期进行老年全髋关节置换手术患者80例,根据随机数字表法分为股神经入路阻滞组(A组,n=40)和髂筋膜间隙入路阻滞组(...目的比较超声引导下股神经阻滞和髂筋膜阻滞在老年患者全髋关节置换术中的麻醉效果。方法选择徐州仁慈医院2020年1—12月择期进行老年全髋关节置换手术患者80例,根据随机数字表法分为股神经入路阻滞组(A组,n=40)和髂筋膜间隙入路阻滞组(B组,n=40)。两组均在超声引导下进行,比较分析两组患者术中丙泊酚、瑞芬太尼的用量及不同时间点心率(HR)、平均脉动压(MAP),比较分析术后不同时间点静态疼痛视觉模拟评分(VAS)、PCA自控使用次数、不良反应发生率和患者满意度。结果B组丙泊酚、瑞芬太尼的术中用量低于A组(P<0.05),B组术中15、30 min MAP,术后6、12、24 h静态VAS评分低于A组(P<0.05);B组术后PCA的按压次数低于A组(P<0.05)。B组并发症发生率低于A组,总满意度高于A组(P<0.05)。结论超声引导髂筋膜间隙阻滞镇痛在全髋关节置换术患者中的应用效果显著优于股神经阻滞,可有效降低疼痛程度及不良反应发生情况。展开更多
In order to widen the application of microcrystalline magnesite, the microcrystalline magnesite in Sichuan and Tibet area was used as the raw material to prepare light-burned MgO at 700,800,900, 1 000, 1 100 and I 200...In order to widen the application of microcrystalline magnesite, the microcrystalline magnesite in Sichuan and Tibet area was used as the raw material to prepare light-burned MgO at 700,800,900, 1 000, 1 100 and I 200 ~C for 3 h, respectively. Then the physical and chemical properties of the light-burned MgO were detec- ted, and its application prospect was analyzed. The re- sults show that： （1） microcrystalline magnesite com- pletely decomposes forming light-burned MgO calcined at the temperature range of 700 - 1 200 ~C ; the MgO con- tent of the light-burned MgO is higher than 96. 51% ; the chemical activity is 88 - 130 s and the grain size is 40 - 200 nm ; it has the advantages of high purity, high activity and fine grain; （2） the light-burned MgO pre- pared with microcrystalline magnesite can be widely used in many industries; it can be used in refractories indus- try to prepare high-purity sintered magnesia and large crystal fused magnesia, or as an additive for refractory products, etc. ; it can also be used in magnesium chemi- cal industry to prepare electrical grade magnesia, sili- con-steel magnesia, environmental friendly flame retard- ant magnesium hydroxide, magnesium sulfate fertilizer, pharmaceutical grade magnesia, food grade magnesia, etc.展开更多
