研究目的:

1.比较头孢他啶阿维巴坦联合氨曲南不同输注方式治疗产金属β-内酰胺酶碳青霉烯耐药革兰阴性菌引起的复杂性腹腔感染、医院获得性肺炎、呼吸机相关性肺炎、复杂尿路感染或血流感染患者的临床有效性与安全性,为临床使用头孢他啶阿维巴坦联合氨曲南的治疗方案优化提供参考。 2.通过TDM探讨达稳态浓度后头孢他啶阿维巴坦联合氨曲南不同输注方式下头孢他啶、氨曲南及阿维巴坦的暴露量及联合目标获得概率的达标率,并结合临床有效性对给药方案进行优化。  

Objectives of Study:

1. To compare the clinical efficacy and safety of different infusion methods (sequential vs. simultaneous) of ceftazidime-avibactam combined with aztreonam in patients with infections caused by metallo-β-lactamase-producing carbapenem-resistant Gram-negative bacteria, including complicated intra-abdominal infection, hospital-acquired pneumonia, ventilator-associated pneumonia, complicated urinary tract infection, or bloodstream infection, thereby providing evidence for optimizing the clinical use of this combination therapy. 2. To employ therapeutic drug monitoring (TDM) to investigate the drug exposure (of ceftazidime, aztreonam, and avibactam) and the target attainment rate of the joint probability of target attainment (PTA) under different infusion methods at steady-state concentration, and to further optimize the dosing regimen by integrating the findings with clinical efficacy outcomes.
