目的:探讨头孢硫咪对婴幼儿肺炎患儿的血C-反应蛋白(CRP)水平的干预影响。方法:对未能住院的42例婴幼儿肺炎患儿采用头孢硫咪治疗,并对其治疗前及治疗7d后的血CRP水平、临床症状和体征等进行评估。结果:临床有效率为92．86%;血CRP水平从治疗前的45．27±15．70 mg·L~(-1)降至10．38±7．26mg·L~(-1),前后比较有统计学差异(P＜0．01)。结论:头孢硫咪对婴幼儿肺炎患儿的血CRP有较好的干预效果,该药治疗婴幼儿肺炎是可取的、有效的、安全的。 Objective: To investigate the effect of cefmenoxime on the blood levels of C-reactive protein (CRP) in infants with pneumonia. Methods: Forty-two infants with infantile pneumonia who were not hospitalized were treated with cefathiam and their blood CRP levels, clinical symptoms and signs before and 7 days after treatment were assessed. Results: The clinical effective rate was 92.86%. The blood CRP level decreased from 45.27 ± 15.70 mg · L -1 to 10.38 ± 7.26 mg · L -1 before treatment, Before and after a statistically significant difference (P <0.01). Conclusion: Cefmenoxime has a good intervention effect on blood CRP in infants with pneumonia. It is preferable, effective and safe to treat infantile pneumonia.
