Objective analysis of the patients in our hospital emergency use of antibiotics for clinical drug reference. Methods were taken from 2007 to June in a hospital emergency room treatment of patients with prescriptions for which the use of antibiotics and medication to the reasonableness of the statistical analysis. Results from the 5635 case of emergency patients in the use of antimicrobial drugs for the prescription of 2502, accounting for 44.40 percent of prescription volume, 2,327 single medication, the prescription of antibiotics for the total number of 93.01 percent, more than two joint application of antibacterial drugs 175 prescription, the prescription of antibiotics for a total of 6.99 percent. The use of the 11 classes of 68 kinds of antimicrobial agents. Antibiotic use is the highest frequency of cephalosporins, followed by the quinolones, the approach to the administration of oral and intravenous mainly intravenous drug consumption amount of antibiotics amount of 89.97 percent. Conclusion 2007 1 to June emergency patients in our hospital antimicrobial drug use and reasonable analysis of the situation is reasonable, but there are still some problems, should further enhance the level of rational drug use, the application of antibacterial drugs to be safe, reasonable and effective, economic .

滴定，背滴定，标准溶液，一级标准，规范化，终点，滴定误差，指标 滴定是其中的一种物质结合能力的定量试剂测量的过程。按说这是通过一个已知浓度的试剂控制除了物质的溶液，直至两者之间的反应来判断，要完成;的试剂量进行测量。有时它是方便或需要进行增加一个多余的试剂滴定法，然后确定与已知浓度的第二试剂过剩a容量分析。第二个滴定称为回滴定。 在滴定用试剂完全已知的成分被称为标准的解决方案。究其原因与它的浓度是已知的精度设置后，该方法的准确性明确的限制;因为这个原因，许多服务是在标准溶液的准备措施。常用的标准溶液的浓度是抵达两种方式：（1）一个纯化合物仔细测量量与试剂滴定，从重量和体积的测量计算出的浓度;或（2）标准溶液制备溶解的纯试剂在仔细衡量自身的溶剂量，这是一个完全稀释已知体积。在这两种方法，一种高度纯化的化合物 - 称为一级标准要求作为参考材料。据此，该标准溶液的浓度是由一级标准滴定过程称为标准化。 每个滴定目标是在该金额标准的解决方案，以通过化学除等同于物质与它的反应。例如，在钠与硝酸银滴定氯化物等价点达到时只有一个银离子配方的重量已为每个氯离子在样品中分子量介绍。在与氢氧化钠硫酸滴定，等价点发生在两个公式的权重，后者已为前者的每个公式的权重推出。 在滴定等当点是一个理论概念。事实上，我们只能估计通过观察与它相关的解决方案中的物理变化的立场。在滴定地步，这种变化表现出来称为终点，它是希望之间的终点和等价点卷的差异会很小。出现分歧，但是，由于在物理变化和我们的能力，观察他们的不足之处。在分析这将导致错误称为滴定误差
