Abstract

PurposeTo evaluate the effects of fluid administration on microcirculatory alterations in sepsis.MethodsWith a Sidestream Dark Field device, we evaluated the effects of fluids on the sublingual microcirculation in 60 patients with severe sepsis. These patients were investigated either within 24 h (early, n = 37) or more than 48 h (late, n = 23) after a diagnosis of severe sepsis. Hemodynamic and microcirculatory measurements were obtained before and 30 min after administration of 1,000 ml Ringer’s lactate (n = 29) or 400 ml 4% albumin (n = 31) solutions.ResultsFluid administration increased perfused small vessel density from 3.5 (2.9–4.3) to 4.4 (3.7–4.9) n/mm (p < 0.01), through a combined increase in the proportion of perfused small vessels from 69 (62–76) to 79 (71–83) %, p < 0.01) and in small vessel density from 5.3 (4.4–5.9) to 5.6 (4.8–6.3) n/mm (p < 0.01). Importantly, microvascular perfusion increased in the early but not in the late phase of sepsis: the proportion of perfused small vessels increased from 65 (60–72) to 80 (75–84) % (p < 0.01) in the early phase and from 75 (66–80) to 74 (67–81) (p = ns) in the late phase. These microvascular effects of fluids were not related to changes in cardiac index (R2 = 0.05, p = ns) or mean arterial pressure (R2 = 0.04, p = ns).ConclusionsIn this non-randomized trial, fluid administration improved microvascular perfusion in the early but not late phase of sepsis. This effect is independent of global hemodynamic effects and of the type of solution.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
