目的探讨降钙素原在小儿急性阑尾炎诊治中的作用。方法 36例小儿急性阑尾炎患儿作为实验组,以同期收治的36例非感染性疾病患儿为对照组。对比两组患儿降钙素原水平和降钙素原阳性率。结果实验组降钙素原水平高于对照组(P<0.05);实验组降钙素原阳性率为77.8%,高于对照组的8.3%,差异有统计学意义(P<0.05)。结论降钙素原在小儿急性阑尾炎诊治中有着较好的应用效果,值得进行深入研究和推广。 Objective To investigate the role of procalcitonin in the diagnosis and treatment of acute appendicitis in children. Methods Thirty - six children with acute appendicitis in children were selected as the experimental group and 36 children with non - infectious disease admitted in the same period as the control group. The levels of procalcitonin and procalcitonin in two groups were compared. Results The level of procalcitonin in experimental group was significantly higher than that in control group (P <0.05). The positive rate of procalcitonin in experimental group was 77.8%, which was higher than that in control group (8.3%) (P <0.05). Conclusions Procalcitonin has a good effect in the diagnosis and treatment of acute appendicitis in children and deserves further study and promotion.
