【Abstract】 Objective: To explore the role of monitoring vancomycin drug valley concentration in the treatment of ICU patients. Methods: Several ICU patients were treated, and all patients were suspected to be infected with Gram-positive bacteria. A total of 62 patients who participated in the study voluntarily were selected. They were grouped by the serum creatinine clearance rate. Thirty patients were in group Ⅱ below 50 mL / min, a total of 32 patients. The blood concentration monitoring of the two groups was compared. Results: The rate of compliance with plasma concentration in group Ⅰ was higher than that in group Ⅱ (P <0.05). Body weight, age, clearance of blood creatinine, administration dose and plasma albumin level would affect the concentration of vancomycin concentration in plasma. Conclusion: According to the prescribed dose, if the patients drug concentration is not up to the standard, other factors such as age and weight need to be considered.

萬古霉素是目前临床上常用抗菌药,在发挥抗菌作用后存在一定的时间依赖性,对抗革兰阳性菌效果显著。ICU重症患者使用万古霉素防治感染效果较好,经多年临床实践验证,万古霉素按照推荐剂量给药后,其血药谷浓度维持在10~20mg/L为最佳浓度[1]。ICU患者用药受个体差异影响,按照推荐剂量用药后部分患者的血药谷浓度很难维持在有效范围,因此给予ICU患者万古霉素后需实时监测其血药谷浓度变化,有利于随时调整药物用量。本次研究重点探讨血药谷浓度监测在ICU肾衰患者中的应用,详细如下。
1 资料与方法
1.1 临床资料
就诊于我院的数名ICU患者中,有62例患者家属自愿参与本研究,按照血肌酐清除率对患者分组,Ⅰ组、Ⅱ组各30例、32例,病例选取时间:2018年1月到2019年11月。患者均为成年人,最大79岁,最小20岁,平均(32.15±2.35)岁。两组男女比例均衡,近期未接受过万古霉素治疗,患者确诊或疑诊为耐甲氧西林革兰阳性菌感染,两组基线资料具有同质性(P>0.05),可对比。
1.2 方法
(1)用药:两组患者均给予万古霉素治疗,万古霉素由美国礼来公司提供,参照万古霉素用药标准给予患者25~30 mg/kg/d剂量,促使机体快速达到血药谷标准范围。给药方法:万古霉素1g+0.9%氯化钠注射液100ml,ivgtt;控制输液速度,保证持续输注时间>1h。两组分别按照1g,q12h和1g,qd给药,分别给药5次,在第5次给药前开始监测血药谷浓度,未达到有效谷浓度者及时调整给药剂量,直至患者血药谷浓度维持在10~20mg/L。……p>
