目的观察烧伤后脓毒症患者血清PCT水平变化。方法本组共计53例烧伤患者,其中无感染组(对照组)42例,脓毒症组11例。应用半定量固相免疫测定法测定患者血清PCT水平。结果无感染患者血中PCT正常或轻度升高,感染脓毒症患者血中PCT明显高于无感染患者。同时感染脓毒症组患者血清PCT水平第4天与第1天相比无差异,第7、10天与第1天相比均有显著差异。结论血清PCT值有助于早期诊断烧伤后脓毒症,且血中PCT水平与感染程度密切相关。
Objective To observe the changes of serum PCT levels in patients with sepsis after burn. Methods A total of 53 cases of burn patients, including no infection group (control group) 42 cases, sepsis group 11 cases. Serum PCT levels were measured by semi-quantitative solid phase immunoassay. The results of non-infected patients with PCT normal or slightly elevated blood PCT in patients with sepsis was significantly higher than the non-infected patients. Serum PCT levels in patients with sepsis at the same time on the 4th day compared with the first day was no difference, on the 7th and 10th days compared with the first day were significantly different. Conclusions Serum PCT value is helpful for the early diagnosis of post-burn sepsis, and the level of PCT in blood is closely related to the degree of infection.
