研究目的:

本研究旨在建立头孢曲松的肺部群体药代动力学/药效学(PPK/PD)模型,通过整合循证医学证据与模型模拟,制定头孢曲松在儿童CAP患者中的个体化给药策略,以确保患儿在初始抗感染治疗中最大化获益。  

Objectives of Study:

This study aims to establish a population pharmacokinetic/pharmacodynamic (PPK/PD) model for ceftriaxone in the lungs, and through integrating evidence-based medicine and model simulation, develop an individualized dosing strategy for ceftriaxone in pediatric patients with community-acquired pneumonia (CAP), to ensure that children maximize their benefits during initial anti-infective treatment.
