目的探讨血小板四项参数的动态变化对危重患儿预后评估的意义。方法采用全自动血球计数仪动态测定56例危重患儿血小板四项参数,分析血小板四项参数与病情预后的关系。结果MPV在死亡组患儿均明显小于存活组,PLT、PCT、PDW在入科1h时无显著性差异,存活组PLT均在正常范围,恶化组PLT持续下降,MPV、PCT、PDW在各组随时间变化趋势不明显。结论PLT、MPV的动态变化对判断危重患儿病情及预后有重要帮助。
Objective To investigate the significance of the dynamic changes of four platelet parameters in the prognosis evaluation of critically ill children. Methods Four parameters of platelet in 56 cases of critically ill children were determined by automatic hemocytometer, and the relationship between the four parameters of platelet and the prognosis was analyzed. Results MPV in the death group was significantly less than that in the surviving group. There was no significant difference in PLT, PCT, and PDW between 1 and 3 h in the surviving group. PLT in the surviving group was in the normal range. Trend with time is not obvious. Conclusion The dynamic changes of PLT and MPV are important to judge the condition and prognosis of critically ill children.
