目的:探讨CRP快速测定在早产儿疾病诊断中的参考价值。方法:用Quik Read CRP分析仪测定CRP值,同时测定WBC值,并对早产儿进行CRP连续监测。结果:感染性疾病早产儿CRP值显著高于非感染性疾病早产儿;在疗效监测中CRP比WBC敏感。结论:CRP在感染性疾病中显著提高,可作为早期诊断指标。因CRP值更能反映炎性疾病的转归过程,用于监测抗生素疗效较WBC敏感。Quik Read CRP分析仪能迅速测定,可实现POCT标准化管理,临床应用较好。 Objective: To investigate the rapid diagnostic value of CRP in the diagnosis of premature infants. METHODS: The CRP values ​​were measured with a Quik Read CRP analyzer, meanwhile WBC values ​​were determined, and CRP was monitored continuously in preterm infants. Results: CRP in preterm infants with infectious diseases was significantly higher than that in premature infants with noninfectious diseases. CRP was more sensitive than WBC in the monitoring of therapeutic efficacy. Conclusion: CRP is significantly increased in infectious diseases and can be used as an early diagnostic indicator. Because the CRP value reflects the prognosis of inflammatory diseases more, it is more sensitive than WBC to monitor the antibiotic efficacy. Quik Read CRP analyzer can quickly determine the POCT can be standardized management, clinical application is better.
