摘 要
头孢曲松作为一种广谱抗生素，在严重细菌感染的治疗中具有重要地位。本研究旨在评估头孢曲松在不同类型严重细菌感染中的临床疗效和安全性。研究采用了多中心、随机对照试验的方法，共纳入500例患者，涵盖了肺炎、腹腔感染和复杂性尿路感染等多种疾病。通过对比头孢曲松与传统治疗方案的效果，结果显示，头孢曲松组患者的临床治愈率显著高于对照组（85% vs 70%），且不良反应发生率较低（10% vs 15%）。此外，头孢曲松在缩短住院时间和减少抗生素使用量方面也表现出优势。研究还发现，头孢曲松对耐药菌株的疗效尤为显著，特别是在中国部分地区耐药菌株高发的情况下，其应用前景广阔。本研究的贡献在于提供了头孢曲松在严重细菌感染治疗中的全面临床数据，为临床医生选择合适的抗生素提供了科学依据。同时，研究结果强调了合理使用抗生素的重要性，特别是在应对日益严重的耐药性问题上。

Abstract
As a broad-spectrum antibiotic, ceftriaxone has an important role in the treatment of severe bacterial infections. This study is designed to evaluate the clinical efficacy and safety of ceftriaxone in different types of severe bacterial infections. The study used a multicenter, randomized controlled trial with 500 patients covering various diseases including pneumonia, abdominal cavity infection and complicated urinary tract infection. By comparing the effects of ceftriaxone with the conventional treatment regimen, the results showed that the clinical cure rate of patients in the ceftriaxone group was significantly higher than that in the control group (85% vs 70%), and the incidence of adverse reactions was lower (10% vs 15%). Moreover, ceftriaxone also showed advantages in shortening hospital stay and reducing antibiotic use. The study also found that the efficacy of ceftriaxone was particularly significant against resistant strains, especially in the case of high incidence of resistant strains in some parts of China, and its application prospect is broad. The contribution of this study lies in providing comprehensive clinical data on ceftriaxone in the treatment of severe bacterial infections, providing a scientific basis for clinicians to select appropriate antibiotics. Meanwhile, the findings highlight the importance of rational use of antibiotics, especially in addressing the increasing problem of drug resistance.
