Crit Care:细菌培养阴性和阳性的脓毒症或脓毒症休克患者结局哪个好?

2021-05-17 MedSci原创 MedSci原创

细菌培养阳性或阴性与脓毒症或脓毒症休克患者的死亡率无关。此外,细菌培养阳性的脓毒症患者的ICU住院时间、机械通气需求和肾脏置换需求与培养阴性患者相似。

细菌培养阴性和阳性的脓毒症患者死亡率和其他临床结局的记录并不一致,而且具有较大的争议。

近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,该系统评价和荟萃分析旨在比较细菌培养阴性和阳性的脓毒症或脓毒症休克患者的临床结局。

研究人员在PubMed、Cochrane和Embase数据库中检索了从数据库成立到2021年1月1日期间发表的研究,并纳入了涉及脓毒症或脓毒症休克患者的研究。所有研究都报道了该分析的主要结局:全因死亡率,并明确比较了细菌培养阴性和阳性患者与临床相关的次要结局(ICU住院时间、住院时间、机械通气需求、机械通气时间和肾脏替代需求)。结果通过比值比(OR)和平均差异(MD)及95%可信区间(CI)来展示。

全因死亡率

7项研究包含22655名患者。本Meta分析的主要结局显示,两组间的全因死亡率无统计学差异(OR=0.95;95%CI, 0.88-1.01;P=0.12;Chi-2=30.71;I2=80%)。次要结局显示,两组患者在ICU的住院时间(MD=−0.19;95%CI为−0.42-0.04;P=0.10, Chi-2=5.73;I2=48%)、机械通气要求(OR=1.02;95%CI:0.94-1.11;P=0.61;Chi2=6.32;I2=53%)和肾脏替代需要量(OR=0.82;95%CI: 0.67-1.01;P=0.06;Chi-2=1.21;I2=0%)差异无统计学意义。培养阳性组住院时间长于培养阴性组(MD=−3.48;95%CI为−4.34至−2.63;P<0.00001;Chi-2=1.03;I2=0%)。培养阳性组的机械通气时间长于培养阴性组(MD=−0.64;95%CI为−0.88至−0.4;P<0.00001;Chi-2=4.86;I2=38%)。

由此可见,细菌培养阳性或阴性与脓毒症或脓毒症休克患者的死亡率无关。此外,细菌培养阳性的脓毒症患者的ICU住院时间、机械通气需求和肾脏置换需求与培养阴性患者相似。脓毒症培养阳性患者的住院时间和机械通气时间均长于培养阴性患者
