摘要 目的探讨小儿反应性血小板增多症与高血清钾的相关关系及临床意义。方法选择就诊患儿256例(排除血液病、肾功能不全、川崎病、脱水等),用全血细胞计数检测血小板,用离子选择电极法测定血清和血浆钾。结果小儿血小板数增多占25.4%,以肺炎、败血症、支气管炎和急性上呼吸道感染增高为多见。血小板增多组血清钾增高率明显高于正常组(29.2%对8.3%,P<0.001);前者血清钾为(5.41±1.18)mmol/L,后者为(4.25±0.81)mmol/L,两组比较差异有统计学意义(P<0.01),而两组血浆钾比较差异无统计学意义(P>0.05);超过这个范围血小板数与血清钾呈正相关,血清钾Y(mmol/L)=0.0035X+3.62(血小板数×109/L),r=0.72。结论感染是血小板反应性增多的重要原因;血小板增多可因人工分离血清致血清钾假性增高。
