目的对慢性肺心病患者血小板减少的原因及应对策略进行初步探讨。方法从检测、感染、并发症、药物等方面入手进行分析。结果其原因较复杂,因素不同,预后不同,感染和药物是其主要因素。结论有必要辨识其产生的原因,为下一步处理提供依据。原则上,要动态观察血小板变化,积极控制感染,改善心肺功能,纠正缺氧和酸碱失衡,慎用可致血小板减少的药物。 Objective To investigate the causes and strategies of thrombocytopenia in patients with chronic cor pulmonale. Methods From testing, infection, complications, drugs and other aspects of the analysis. The results of its more complex causes, different factors, different prognosis, infection and drugs are its main factors. Conclusion It is necessary to identify the causes of its occurrence, to provide the basis for the next step. In principle, to dynamically observe changes in platelets, and actively control the infection, improve heart and lung function, correct hypoxia and acid-base imbalance, caution can cause thrombocytopenia drugs.
