目的探讨小儿支气管肺炎4项血小板参数的变化及意义。方法观察300例小儿支气管肺炎(重症肺炎130例,轻症肺炎170例)患者的血小板计数(PLT)、血小板压积(PCT)、平均血小板体积(MPV)及血小板分布宽度(PDW)的变化,并与80例正常对照组比较。结果重症肺炎组与轻症肺炎组急性期4项血小板参数比对照组均显著升高(P﹤0.01);重症肺炎组急性期4项血小板参数比轻症肺炎组急性期显著升高(P﹤0.01);重症肺炎组与轻症肺炎组恢复期4项血小板参数比急性期均显著降低(P﹤0.01),并恢复正常。结论小儿支气管肺炎急性期4项血小板参数均异常升高,升高程度与病情相关。
Objective To investigate the changes of four platelet parameters in children with bronchial pneumonia and its significance. Methods The changes of platelet count (PLT), platelet pressure (PCT), mean platelet volume (MPV) and platelet distribution width (PDW) in 300 children with bronchopneumonia (130 severe pneumonia and 170 mild pneumonia) And compared with 80 normal control group. Results The four platelet parameters of severe pneumonia group and mild pneumonia group were significantly higher than those of the control group (P <0.01). The four platelet parameters of acute pneumonia group were significantly higher than those of mild pneumonia group (P < 0.01). The four platelet parameters in the severe pneumonia group and the mild pneumonia group were significantly lower than those in the acute phase (P <0.01), and returned to normal. Conclusion The four platelet parameters in children with acute bronchial pneumonia are abnormally elevated, and the degree of increase is related to the condition.
