Liver Int:急性肾损伤而败血症是侵入性操作后失代偿性肝硬化患者出血的独立预测因子

2018-02-09 MedSci MedSci原创

此研究表明,急性肾损伤,而不是脓毒症,是失代偿性肝硬化患者术后出血的最重要的预测因子

低风险的侵入性操作后出血可能危及生命,或可导致失代偿性肝硬化患者进一步并发症的发生。在未分层的住院肝硬化患者的研究队列中,尽管凝血参数异常,但侵入性操作相关出血率较低。本研究旨在鉴定侵入性操作出血风险较高的失代偿肝硬化患者,同时评估术前输血的价值。

本研究纳入2012年1月至2016年8月间,发生由CT确认的穿刺后腹腔积血的住院肝硬化患者。将研究对象与同一时期,怀疑发生穿刺后腹腔积血,但由CT排除的患者,进行比较。进行了回顾性的图表回顾,以确定不良事件的具体情况、患者的特征以及出血的危险因素。

多元分析表明,在穿刺前,急性肾损伤(AKI)是穿刺后腹腔积血的唯一独立预测因子(OR 4.3, 95% CI 1.3 - 13.5, p= 0.01),独立于MELD评分,大容量穿刺术,脓毒症,血小板,INR,和血红蛋白水平等因素。

感染/败血症通常被认为是肝硬化出血的前兆。此研究表明,急性肾损伤,而不是脓毒症,是失代偿性肝硬化患者术后出血的最重要的预测因子。虽然终末期肾脏疾病是导致非肝硬化患者出血的已知原因,但目前尚无研究证实急性肾损伤是肝硬化侵入性操作出血的危险因素。需要进一步的研究去证实是否需要在患有急性肾损伤的肝硬化患者进行侵入性操作前,进行输血。
