老年慢性肺心病并发多脏器功能衰竭66例分析

Analyze 66 cases with the multisystem organ failume and the aged chronic cor pulmonale

目的：探讨多脏器功能衰竭与死亡率之间的关系。方法：对１６４例肺心病合并多脏器功能衰竭６６例患者根据累及脏器数目分成四组，对计数资料进行Ｘ２检验，并对组间资料作分割性Ｘ２检验，并分析其诱因构成。结果：死亡率随脏器功能衰竭数目增多而增加（Ｘ２＝２５．１６Ｐ＜０．０１）；感染是多脏器功能衰竭的重要诱因（占９６．９７％）。结论：降低多脏器功能衰竭的发生率对提高抢救成功率，降低死亡率至关重要，其关键在于积极治疗原发病的同时，努力防治诱发因素。

Objective:Discuss the relationship between the multisystem organ failure(MOF) and the mortality rate.Methods:According to the number of the complicated viscera,66 cases of MOF in 164 cases of the cor pulmonale are divided into four groups.Qualitative data in every group are examined by x2test and between two different groups are examined by segment x2test;Analyze the form of the remote causes in MOF.Results:The mortality rate increases while the number of the complicated viscera adds(X2=25.16, P <0.01),The infection is an important remote cause in MOF(occupy 96.97%).Conclude:The decrease in the occur rate of MOF is very important to improve the success rate of the salvage and to reduce the mortality rate.The key is to treat actively the primary affection meanwhile,prevent and cure the remote cause.
