临床采用静脉滴注抗菌素很多,从调查我门诊部今年1～5月份静滴记录,初步发现有以下几种情况。常用的输液pH值范围较大,含葡萄糖的输液pH值一般较低,因此,往往影响到与之混合的注射剂的稳定性,特别是那些在酸性下不稳定的抗菌素影响更显著。药典规定葡萄糖注射液的pH范围是3.2～5.5,在此最高与最低氢离子浓度之间,其氢离子浓度 Clinical use of intravenous antibiotics a lot, from the investigation of my clinics 1 to 5 intravenous infusion records this year, initially found the following situations. Commonly used infusion pH range, pH-containing infusion of glucose is generally low, therefore, often affect the stability of the injection mixed with them, especially those under the acidic instability of antibiotics more significant impact. Pharmacopoeia provides glucose injection pH range of 3.2 to 5.5, between the highest and lowest hydrogen ion concentration, the hydrogen ion concentration
