Sodium bicarbonate in treating lactic and non-lactic metabolic acidosis at different chloride levels: a retrospective study.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSodium bicarbonate is commonly used to correct metabolic acidosis in pediatric patients, yet its efficacy remains controversial. This study aims to assess its effectiveness in treating non-lactic and lactic metabolic acidosis and its impact at various chloride levels.
methodsA retrospective cohort study was conducted by screening pediatric patients diagnosed with metabolic acidosis from a paediatric intensive care database. Patients were categorized into two groups: lactate patients (lactate > 2.0 mmol/L) and non-lactate patients (lactate ≤ 2.0 mmol/L). The risk of death in patients who received sodium bicarbonate was assessed.
resultsSodium bicarbonate treatment did not significantly affect in-hospital mortality in either overall lactate patients or non-lactate patients, with adjusted OR of 1.044 (95% CI: 0.829-1.315, p = 0.714) and 0.838 (95% CI: 0.548-1.281, p = 0.414), respectively. In lactate patients, those receiving sodium bicarbonate had a higher risk of in-hospital death when chloride was < 107 mmol/L (adjusted OR = 2.195, 95% CI: 1.536-3.135, p < 0.001), whereas the risk of in-hospital death decreased when chloride was ≥ 113 mmol/L (adjusted OR = 0.365, 95% CI: 0.217-0.614, p < 0.001). Similar findings were observed in non-lactate patients.
conclusionsSodium bicarbonate treatment does not improve the survival of pediatric patients with lactate or non-lactate metabolic acidosis. However, it can reduce the odds of mortality in pediatric patients with hyperchloremia, regardless of their lactate levels. Prospective studies are needed to further confirm these findings.
