Methods: Patients (N = 32) were divided into four groups based on amikacin administration timing and groups received drug minutes to hours after injury. In Groups A, B, C, and D, amikacin (400 mg, IV) was administered 3 - 4, 10, 20 and 30 h post burn injury, respectively (N = 8 for all groups). Next blister fluid and venous blood samples from 9 patients were obtained at 0, 0.25, 0.5, 1, 2, 3, 4, 5, 6, and 7 h after drug infusion. Amikacin concentrations were measured with a fluorescent polarization immunoassay and pharmacokinetics was deduced using DAS3.2.5. Statistical analyses performed with SPSS13.0. Results: Compared with normal values, t1/2z of amikacin from burn patients was shortened in serum but amikacin half-lives in blister fluid was significantly greater than serum half-life values (p < 0.05). Groups A and B had greater pharmacokinetic values at each time point, and Group D did not achieve antibacterial concentrations of amikacin. Conclusion: Early amikacin administration in severe burn patients offers greater concentrations of drug in serum and blister fluids.展开更多

文摘目的:探讨降钙素原(procalcitonin,PCT)、血小板(platelet,PLT)在危重烧伤患者中的水平变化及其临床意义。方法:回顾性分析2018年2月至2020年2月北京积水潭医院92例危重烧伤患者的临床资料,比较患者于入院时、入院后24 h时、入院后48 h时PCT和PLT水平,根据临床预后的不同将其分为存活组(n=60)与死亡组(n=32),比较两组一般资料情况,观察临床预后的相关影响因素并对其进行logistic回归分析,采用受试者工作特征(receiver operative characteristic,ROC)曲线分析PCT、PLT对危重烧伤患者预后的预测价值,曲线下面积(area under the curve,AUC)表示预测的准确度。对PCT、PLT水平与危重烧伤患者烧伤修复评级进行相关性分析。结果:危重烧伤患者于入院时、入院后24 h时、入院后48 h时PCT水平逐渐升高,PLT水平逐渐减低,差异均具有统计学意义(P<0.05);PCT、PLT水平是危重烧伤患者死亡的独立影响因素(P<0.05),ROC曲线分析结果显示,PCT、PLT及PCT联合PLT对危重烧伤患者临床预后均具有预测价值(P<0.05),且PCT联合PLT的AUC大于PCT、PLT,差异均具有统计学意义(P<0.05)。PCT、PLT水平与危重烧伤患者烧伤修复评级呈显著相关性(P<0.05)。结论:危重烧伤患者短期内PCT水平逐渐升高,PLT水平逐渐减低;PCT>29.78μg/L,PLT<71.45×109/L是危重烧伤患者死亡的独立危险因素,PCT、PLT水平与危重烧伤患者临床预后、烧伤修复密切相关,有望成为临床预测危重烧伤患者预后、烧伤修复的新指标。
