Purpose
Net ultrafiltration (UFNET) during continuous renal replacement therapy (CRRT) can control fluid balance (FB), but is usually 0 ml·h−1 in patients with vasopressors due to the risk of hemodynamic instability associated with CRRT (HIRRT). We evaluated a UFNET strategy adjusted by functional hemodynamics to control the FB of patients with vasopressors, compared to the standard of care.
Methods
In this randomized, controlled, open-label, parallel-group, multicenter, proof-of-concept trial, adults receiving vasopressors, CRRT since ≤ 24 h and cardiac output monitoring were randomized (ratio 1:1) to receive during 72 h a UFNET ≥ 100 ml·h−1, adjusted using a functional hemodynamic protocol (intervention), or a UFNET ≤ 25 ml·h−1 (control). The primary outcome was the cumulative FB at 72 h and was analyzed in patients alive at 72 h and in whom monitoring and CRRT were continuously provided (modified intention-to-treat population [mITT]). Secondary outcomes were analyzed in the intention-to-treat (ITT) population.
Results
Between June 2021 and April 2023, 55 patients (age 69 [interquartile range, IQR: 62; 74], 35% female, Sequential Organ Failure Assessment (SOFA) 13 [11; 15]) were randomized (25 interventions, 30 controls). In the mITT population, (21 interventions, 24 controls), the 72 h FB was −2650 [−4574; −309] ml in the intervention arm, and 1841 [821; 5327] ml in controls (difference: 4942 [95% confidence interval: 2736–6902] ml, P < 0.01). Hemodynamics, oxygenation and the number of HIRRT at 72 h, and day-90 mortality did not statistically differ between arms.
Conclusion
In patients with vasopressors, a UFNET fluid removal strategy secured by a hemodynamic protocol allowed active fluid balance control, compared to the standard of care.

对于需要持续肾脏替代治疗的急性循环衰竭患者,通过血流动力学监测确保体液平衡中和与方案化护理标准:GO NEUTRAL 随机对照试验的结果
目的
连续性肾脏替代疗法 (CRRT) 期间的净超滤 (UF NET) 可以控制液体平衡 (FB),但由于与 CRRT (HIRRT) 相关的血流动力学不稳定的风险,血管加压药患者的净超滤 (UFNET) 通常为 0 ml·h-1。与标准护理相比,我们评估了通过功能性血流动力学调整的 UFNET 策略,以控制血管加压药患者的 FB。
方法
在这项随机、对照、开放标签、平行组、多中心、概念验证试验中,接受血管加压药、≤ 24 小时后接受 CRRT 和心输出量监测的成人被随机分配(比例 1:1)在 72 小时内接受 100 ml·h-1 的 UF ≥NET,使用功能性血流动力学方案(干预)进行调整,或≤ 25 ml·h-1 的 UFNET(控制)。主要结局是 72 h 时的累积 FB,并在 72 h 活着的患者中进行分析,并持续提供监测和 CRRT (改良意向治疗人群 [mITT])。在意向治疗 (ITT) 人群中分析次要结局。
结果
在 2021 年 6 月至 2023 年 4 月期间,随机分配了 55 例患者 (年龄 69 [四分位距,IQR: 62;74],35% 为女性,序贯器官衰竭评估 (SOFA) 13 [11;15])(25 项干预,30 项对照)。在 mITT 人群中(21 项干预,24 名对照),干预组的 72 小时 FB 为 -2650 [-4574;-309] ml,对照组为 1841 [821;5327] ml(差异:4942 [95% 置信区间:2736–6902] ml,P < 0.01)。血流动力学、氧合和 72 小时 HIRRT 数量以及 90 天死亡率在两组之间没有统计学差异。
结论
在血管加压药患者中,与标准护理相比,由血流动力学方案保护的 UFNET 液体清除策略允许主动液体平衡控制。
