摘要
目的 利用蒙特卡洛模拟法优化舒巴坦在重症连续性静脉-静脉血液滤过患者中的给药方案.方法 收集舒巴坦在重症连续性静脉-静脉血液滤过患者的药动学/药效学(PK/PD)参数与鲍曼不动杆菌最低抑菌浓度(MIC),进行5 000次蒙特卡洛模拟,评估给药方案的合理性.鲍曼不动杆菌的PK/PD靶值为40%fT>MIC和60%fT>MIC.结果 对于鲍曼不动杆菌引起的重症连续性静脉-静脉血液滤过患者,当MIC=4 mg-L-1时,推荐给药方案分别为0.5 h传统静脉输注1 g,q8h和1 g,q6h.在2种PK/PD靶值下推荐的经验性给药方案分别是24 h连续性静脉输注9 g,q24h和12 g,q24h.结论 针对敏感率较低的鲍曼不动杆菌菌株,推荐采用3 h延长静脉输注或24 h连续性静脉输注的给药方案.
Abstract
AIM To optimize sulbactam regimens for intensive care unit(ICU)continuous veno-venous hemofiltration(CVVH)patients using the Monte Carlo simulation method.METHODS Pharmacokinetic/pharmacodynamic(PK/PD)parameters of sulbactam in ICU CVVH patients and the minimum inhibitory concentration(MIC)of Acinetobacter baumannii(AB)were collected.Monte Carlo simulations(n=5 000)were conducted to assess the rationality of the dosing regimen.The PK/PD target values for AB were 40%fT>MIC and 60%fT>MIC.RESULTS For ICU patients with CVVH caused by AB,when the MIC was 4 mg·L-1,the recommended dosing regimens were traditional intravenous infusions of 1 g,q8h and 1 g,q6h(with each dose infused over 0.5 h).The empiric dosing regimens recommended under 2 PK/PD target values were 24-hour continuous intravenous infusion of 9 g,q24h and 12 g,q24h.CONCLUSION It is recommended to use either a 3-hour extended intravenous infusion or a 24-hour continuous intravenous infusion regimen for the treatment of AB strains with lower susceptibility.
