重症患者万古霉素血清谷浓度监测的临床研究

Clinical research for trough value of serum vancomycin in critical patients

摘要:

目的 通过观察重症患者万古霉素血清谷浓度的变化,探讨重症患者最优化的万古霉素给药方案.方法 采用回顾性研究方法,选择2010年7月至2012年5月入住中山大学附属第一医院外科重症监护病房(SICU)使用并监测万古霉素血清谷浓度的重症患者66例,根据内生肌酐清除率(CCr)将患者分为CCr正常组(≥70 mL/min)和CCr减退组(<70 mL/min)两组,分析万古霉素血清谷浓度分布情况、谷浓度与CCr之间的关系及其对患者预后的影响,比较两组患者万古霉素的实际使用剂量与指南推荐剂量的差别.结果 66例患者共收集119例次万古霉素血清谷浓度值,仅24例次(20.17%)达到目标浓度(15 ~ 20 mg/L),54例次(45.38%)<15 mg/L,41例次(34.45%)>20 mg/L.CCr正常组(55例次)万古霉素血清谷浓度为(13.11±6.84) mg/L,其中65.5%<15 mg/L;亚组分析显示,谷浓度达标患者实际用药剂量明显低于推荐剂量(g/d:1.95±0.61比2.73±0.32,F=1.739,P=0.001).CCr减退组(64例次)万古霉素血清谷浓度为(20.49±8.12) mg/L,其中51.5%>20 mg/L;亚组分析显示,谷浓度达标患者的实际用药剂量高于推荐剂量,但差异无统计学意义(g/d:1.08±0.49比0.78±0.19,F=11.294,P=0.062).万古霉素血清谷浓度达标者28 d病死率[22.2%(4/18)]与未达标者28 d病死率[18.8%(9/48)]比较差异无统计学意义(x2=0.009,P=0.924).多重线性回归分析显示,血肌酐[优势比(OR)=1.001,95%可信区间(95%CI)为0.990~1.012,P=0.000]、给药剂量(OR=0.600,95% CI为0.251 ~ 1.434,P=0.003)、年龄(OR=0.985,95%CI为0.955 ~ 1.015,P=0.015)和体质量(OR=1.013,95%CI为0.967~ 1.062,P=0.022)是影响万古霉素血清谷浓度的主要因素.结论 重症患者万古霉素血清谷浓度临床达标率低,因此临床有监测的必要;血肌酐、给药剂量、年龄和体质量对万古霉素血清谷浓度影响较大,制定给药方案时应充分考虑这些因素.

Objective To observe the changes in serum vancomycin trough concentration,and explore its optimal dosage in critical patients.Methods A retrospective study was conducted.Data of 66 patients who used vancomycin during July 2010 to May 2012 in surgical intensive care unit (SICU) of the First Affiliated Hospital of Sun Yat-Sen University were collected and analyzed.According to the endogenous creatinine clearance rate (CCr),the patients were divided into two groups:CCr normal group (≥ 70 mL/min) and CCr lowered group (<70 mL/min).The distribution of vancomycin serum trough concentration between two groups,relationship between vancomycin serum trough concentrations and CCr,and the influence of vancomycin serum trough concentrations on the prognosis was analyzed.The difference between actual dosage and the recommended dosage in guideline was compared between two groups.Results 119 times of vancomycin serum trough concentration in 66 patients were enrolled,and it was found that only 20.17% (24/119) reached the target concentration (15-20 mg/L),45.38% (54/119)< 15 mg/L and 34.45% (41/1 19) >20 mg/L.Vancomycin serum trough concentration in CCr normal group (55 cases) was (13.11 ± 6.84) mg/L,among them 65.5% (36/55) attained lower trough concentrations (< 15 mg/L).In the subgroup with 15-20 mg/L trough serum concentrations,vancomycin doses were significantly lower than that of recommendation (g/d:1.95 ± 0.61 vs.2.73 ± 0.32,F=1.739,P=0.001).Vancomycin serum trough concentration in CCr lowered group (64 cases) was (20.49 ± 8.12) mg/L,with 51.5% (33/64) of them showed higher trough concentrations (>20 rag/L).In the subgroup with 15-20 mg/L vancomycin trough serum concentration,vancomycin doses were higher than that of recommendation (g/d:1.08 ±0.49 vs.0.78 ±0.19,F=11.294,P=0.062).There was no significant difference in 28-day mortality between patients with targeting trough serum concentrations and those without [22.2% (4/18) vs.18.8% (9/48),x2=0.009,P=0.924].Serum creatinine [odds ratio (OR)=1.001,95% confidence interval (95%CI):0.990-1.012,P=0.000],vancomycin doses (OR=0.600,95%CI:0.251-1.434,P=0.003),age (OR=0.985,95%CI:0.955-1.015,P=0.015) and body mass index (OR=1.013,95%CI:0.967-1.062,P=0.022) were found to be correlated to serum trough concentrations by multiple linear regression analysis.Conclusions The rate of vancomycin serum trough concentrations reaching the standard is low in critical patients,so constant monitoring is necessary.Creatinine,vancomycin dosage,age and body mass index show a relatively significant influence on the serum trough concentrations,and they should be taken into consideration in dosage to be given.
