1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

objectiveTo test the hypothesis that, in resuscitated septic shock patients, central venous-to-arterial carbon dioxide difference [P(cv-a)CO(2)] may serve as a global index of tissue perfusion when the central venous oxygen saturation (ScvO(2)) goal value has already been reached.

designProspective observational study.

settingA 22-bed intensive care unit (ICU). PATIENTS: After early resuscitation in the emergency unit, 50 consecutive septic shock patients with ScvO(2) > 70% were included immediately after their admission into the ICU (T0). Patients were separated in Low P(cv-a)CO(2) group (Low gap; n = 26) and High P(cv-a)CO(2) group (High gap; n = 24) according to a threshold of 6 mmHg at T0. MEASUREMENTS: Measurements were performed every 6 h over 12 h (T0, T6, T12).

resultsAt T0, there was a significant difference between Low gap patients and High gap patients for cardiac index (CI) (4.3 +/- 1.6 vs. 2.7 +/- 0.8 l/min/m(2), P < 0.0001) but not for ScvO(2) values (78 +/- 5 vs. 75 +/- 5%, P = 0.07). From T0 to T12, the clearance of lactate was significantly larger for the Low gap group than for the High gap group (P < 0.05) as well as the decrease of SOFA score at T24 (P < 0.01). At T0, T6 and T12, CI and P(cv-a)CO(2) values were inversely correlated (P < 0.0001).

conclusionIn ICU-resuscitated patients, targeting only ScvO(2) may not be sufficient to guide therapy. When the 70% ScvO(2) goal-value is reached, the presence of a P(cv-a)CO(2) larger than 6 mmHg might be a useful tool to identify patients who still remain inadequately resuscitated.
