Norepinephrine may improve survival of septic shock patients in a low-resource setting: a proof-of-concept study on feasibility and efficacy outside the Intensive Care Unit

Abstract

ABSTRACT 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.
