肝硬化腹水并發(fā)自發(fā)性細(xì)菌性腹膜炎的危險(xiǎn)因素及病原學(xué)分析摘要：

肝硬化腹水是肝硬化的嚴(yán)重并發(fā)癥之一，自發(fā)性細(xì)菌性腹膜炎是腹水患者最常見的感染性并發(fā)癥之一。為了探究自發(fā)性細(xì)菌性腹膜炎在肝硬化腹水中的危險(xiǎn)因素及病原學(xué)分析，本文對相關(guān)文獻(xiàn)進(jìn)行了綜述。

本文認(rèn)為，肝功能不全、腹水累積、上消化道出血、腹腔手術(shù)及糖皮質(zhì)激素使用是肝硬化腹水并發(fā)自發(fā)性細(xì)菌性腹膜炎的主要危險(xiǎn)因素。其中，肝功能不全是導(dǎo)致自發(fā)性細(xì)菌性腹膜炎的最主要因素之一。此外，本文還分析了自發(fā)性細(xì)菌性腹膜炎病原學(xué)及其感染特點(diǎn)，認(rèn)為腸道菌群的失衡是自發(fā)性細(xì)菌性腹膜炎的重要病因之一。

本文的研究結(jié)論有助于了解肝硬化腹水并發(fā)自發(fā)性細(xì)菌性腹膜炎的病因和危險(xiǎn)因素，對于提高臨床醫(yī)生對該疾病的認(rèn)識、制定更有效的預(yù)防和治療策略具有重要的臨床意義。
