Objective To investigate the prognostic values of serum procalcitonin ( PCT ) test in infantile pneumonia. Methods A total of 120 infant pneumonia cases were collected between January 2009 and December 2010 in our hospital. Serum PCT were tested in all patients both on admission and 72 h later. Relationship between PCT levels and prognosis was analyzed. Results Serum PCT levels on admission were positively correlated with complication rates ( P < 0. 05 ) . Complication rates were significantly higher in individuals with their PCT levels decreased between 15% and 30% and those with PCT decrease rates < 15% than in patients with PCT decreased rates >30% ( P < 0. 05 ) .Conclusion PCT levels are positively related to the prognosis of infantile pneumonia and the slower PCT decreases, the more likely for the infant to develop serious complications.%目的 探讨血清降钙素原(PCT)对婴幼儿肺炎预后的评价作用.方法 收集2009-2010年我科住院的120例婴幼儿肺炎患儿,在入院当日及72 h进行血清PCT检查,观察PCT水平与婴幼儿肺炎预后的关系.结果 入院时血清PCT水平与患儿住院并发症发生率呈正相关(P＜0.05).入院72 h PCT下降率15%～30%及＜15%的患儿并发症发生率明显高于PCT下降率＞30%的患儿,差异有统计学意义(P＜0.05).结论 PCT越高提示婴幼儿肺炎的预后越差,PCT下降的速率越慢婴幼儿越容易发生严重的并发症.
