Septic shock treatment in sub-Saharan African hospitals is challenging due to limited availability of ICUs, central venous catheters, vasopressors, and trained staff. We designed this proof-of-concept study to determine efficacy, safety, and feasibility of norepinephrine (NE) use in a non-intensive setting in a low-resource country, consisting in a peripheral infusion via a mechanical drop counter. Septic shock patients accessing a rural hospital in Uganda were included: the 2020 group (N = 12) was prospectively enrolled (Jan-Mar 2020) when NE was available; the 2019 group (N = 11) was retrospectively enrolled (Oct-Dec 2019). Enrollment was continuous to reduce selection bias. Basic clinical endpoints (noninvasive blood pressure, tissue perfusion, diuresis) defined shock control and the prognostic endpoint was survival at hospital discharge. Shock control at 6 and 12 hours was higher in the 2020 group (p = 0.012 for both). Survival at hospital discharge was 75% and 27.3%, respectively (p = 0.039). NE infusion was associated with a Hazard Ratio of 0.23 (p = 0.041) in a multivariate Cox model. No NE-induced adverse effects were detected. These preliminary results suggest that implementing NE infusion in a low-resource setting without ICU could be a safe and effective strategy in managing septic shock and that this approach could lead to a lower mortality rate.
在撒哈拉以南非洲的医院中,由于 ICU、中心静脉导管、血管加压药和训练有素的医护人员的数量有限,脓毒性休克的治疗具有挑战性。我们设计了这项概念验证研究,以确定去甲肾上腺素(NE)在资源匮乏国家的非强化环境中使用的疗效、安全性和可行性,该方法包括通过机械滴注计数器进行外周输注。乌干达农村医院收治的脓毒性休克患者被纳入本研究:2020 组(N=12)为前瞻性纳入(2020 年 1 月至 3 月),当时有 NE 可用;2019 组(N=11)为回顾性纳入(2019 年 10 月至 12 月)。连续纳入以减少选择偏倚。基本临床终点(无创血压、组织灌注、利尿)定义为休克控制,预后终点为出院时的存活率。2020 组在 6 小时和 12 小时的休克控制率更高(均为 p=0.012)。出院时的存活率分别为 75%和 27.3%(p=0.039)。多变量 Cox 模型显示,NE 输注的风险比为 0.23(p=0.041)。未发现 NE 引起的不良反应。这些初步结果表明,在没有 ICU 的资源匮乏环境中实施 NE 输注可能是管理脓毒性休克的一种安全有效的策略,这种方法可能会降低死亡率。
