目的

探讨CD64指数联合降钙素原(PCT)、白介素-6(IL-6)、血清淀粉样蛋白A(SAA)等血清学指标对重型颅脑损伤(sTBI)术后颅内细菌感染的诊断价值。

方法

选取徐州市肿瘤医院重症医学科自2019年10月至2022年1月行手术治疗后引发颅内细菌感染的60例sTBI患者作为观察组,另将同期在本院接受手术治疗后未引发颅内细菌感染的60例sTBI患者作为对照组,分别对其CD64指数、PCT水平、IL-6水平、SAA水平进行检测,并对CD64指数、PCT、IL-6、SAA联合诊断在sTBI术后颅内细菌感染中的诊断价值进行分析。

结果

与对照组比较,观察组治疗后CD64指数、PCT、IL-6、SAA水平明显更高,差异有统计学意义(P<0.05);多因素分析结果显示,CD64指数、PCT、IL-6、SAA是导致sTBI患者术后颅内感染的独立危险因素(P<0.05);与CD64指数、PCT、IL-6、SAA单独诊断比较,CD64指数+PCT+IL-6+SAA联合诊断的灵敏度、特异度、阳性预测值、阴性预测值明显更高,差异有统计学意义(P<0.05)。

结论

在sTBI患者接受手术治疗后,联合检测CD64指数、PCT、IL-6、SAA水平变化情况可明确患者是否引发颅内细菌感染,为后续治疗提供较为可靠的参考依据。

Objective

To investigate the diagnostic value of CD64 index combined with procalcitonin (PCT), interleukin-6 (IL-6) and serum amyloid A (SAA) for intracranial bacterial infection after severe traumatic brain injury (sTBI).

Methods

Sixty patients with sTBI who had intracranial bacterial infection after receiving surgical treatment from October 2019 to January 2022 in Critical Medicine Department of Xuzhou Tumor Hospital were selected as the observation group, and 60 sTBI patients without intracranial bacterial infection after surgical treatment in the same period were selected as the control group. Their CD64 index, PCT, IL-6 and SAA level were detected respectively, and the combined diagnosis of CD64 index, PCT, IL-6 and SAA level in intracranial bacterial infection after sTBI was analyzed.

Results

Compared with the control group, the levels of CD64 index, PCT, IL-6 and SAA in the observation group were significantly higher after treatment, and the difference was statistically significant (P<0.05). Multivariate analysis showed that CD64 index, PCT, IL-6 and SAA were independent risk factors for intracranial infection in patients with sTBI after surgery (P<0.05); Compared with CD64 index, PCT, IL-6 and SAA, the sensitivity, specificity, positive predictive value and negative predictive value of the combined diagnosis of CD64 index+PCT+IL-6+SAA were significantly higher, and the difference was statistically significant (P<0.05).

Conclusion

After sTBI patients received surgical treatment, the combined detection of CD64 index, PCT, IL-6 and SAA levels can confirm whether the patients have intracranial bacterial infection and provide a reliable reference for subsequent treatment.
