Infection of peritoneal fluid in cirrhotic patients requires an early diagnosis and treatment. Different parameters have been used for the diagnosis of this complication, however, the statistical study has not used multivariable analysis techniques. We have therefore designed this work performing a discriminating analysis in order to find the best variable combination. Twenty-six cirrhotic patients who were consecutively admitted to our hospital have been studied. Total adn polymorphonuclear leukocytes, glucose, LDH, and lactic acid were determined in peritoneal fluid. Eighteen peritoneal fluids were classified as non infected and the rest as infected. The criteria obtained from the discriminating function which combines total leukocytes, LDH, and glucose has been chosen as optimal. The utility of discriminating analysis is discussed and we conclude with the need to verify in a later study the value of the calculated function.
肝硬化患者腹腔积液感染需要早期诊断和治疗。已采用不同参数来诊断这种并发症，然而，统计研究尚未使用多变量分析技术。因此，我们设计了这项工作，进行判别分析以找到最佳变量组合。我们研究了连续入住我院的26例肝硬化患者。测定了腹腔积液中的总白细胞和多形核白细胞、葡萄糖、乳酸脱氢酶和乳酸。18份腹腔积液被分类为未感染，其余为感染。从结合总白细胞、乳酸脱氢酶和葡萄糖的判别函数中获得的标准已被选为最佳标准。讨论了判别分析的效用，我们最后得出结论，需要在后续研究中验证计算出的函数的值。
