Phenylephrine (PE) and norepinephrine (NE) may be used to maintain adequate blood pressure and tissue perfusion in patients with septic shock, but the effect of NE combined with PE (NE-PE) on mortality remains unclear. We hypothesized that NE-PE would not inferior to NE alone for all-cause hospital mortality in patients with septic shock.
This single-center, retrospective cohort study included adult patients with septic shock. According to the infusion type, patients were divided into the NE-PE or NE group. Multivariate logistic regression, propensity score matching and doubly robust estimation were used to analyze the differences between groups. The primary outcome was the all-cause hospital mortality rate after NE-PE or NE infusion.
Among 1, 747 included patients, 1, 055 received NE and 692 received NE-PE. For the primary outcome, the hospital mortality rate was higher in patients who received NE-PE than in those who received NE (49.7% vs. 34.5%, p < 0.001), and NE-PE was independently associated with higher hospital mortality (odds ratio = 1.76, 95% confidence interval = 1.36-2.28, p < 0.001). Regarding secondary outcomes, patients in the NE-PE group had longer lengths of stay in ICU and hospitals. Patients in the NE-PE group also received mechanical ventilation for longer durations.
NE combined with PE was inferior to NE alone in patients with septic shock, and it was associated with a higher hospital mortality rate.
去甲肾上腺素(NE)和苯肾上腺素(PE)可用于维持感染性休克患者的血压和组织灌注,但联合应用 NE 和 PE(NE-PE)对死亡率的影响尚不清楚。我们假设 NE-PE 不会降低感染性休克患者的全因住院死亡率。
这项单中心、回顾性队列研究纳入了成年感染性休克患者。根据输注类型,患者分为 NE-PE 或 NE 组。采用多变量逻辑回归、倾向评分匹配和双重稳健估计来分析组间差异。主要结局为 NE-PE 或 NE 输注后全因住院死亡率。
在纳入的 1747 例患者中,1055 例接受 NE 治疗,692 例接受 NE-PE 治疗。对于主要结局,接受 NE-PE 治疗的患者住院死亡率高于接受 NE 治疗的患者(49.7% vs. 34.5%,p<0.001),且 NE-PE 与更高的住院死亡率独立相关(比值比=1.76,95%置信区间=1.36-2.28,p<0.001)。关于次要结局,NE-PE 组患者 ICU 和医院的住院时间更长。NE-PE 组患者也接受了更长时间的机械通气。
在感染性休克患者中,联合应用 NE 和 PE 不如单独应用 NE,且与更高的住院死亡率相关。
