Outcomes of Extracorporeal Removal in Acute Barium Poisoning: A Scoping Review.
Article in Journal of acute medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Acute barium poisoning, though rare, can cause severe hypokalemia, respiratory paralysis, and life-threatening arrhythmias. Conventional treatments, including potassium replacement, may not rapidly resolve severe toxicity. Extracorporeal removal therapies (ECT), such as hemodialysis (HD) and continuous renal replacement therapy (CRRT), have been used to accelerate barium elimination, but their overall clinical outcomes remain unclear. This scoping review systematically summarizes current literature on the clinical outcomes of ECT in acute barium poisoning. We searched Embase, Ovid MEDLINE, and Cochrane Trials databases up to November 30, 2024. Fourteen articles reporting 15 cases were included. Most cases involved intentional oral ingestion, predominantly with barium chloride. Severe hypokalemia, respiratory paralysis, and serious arrhythmia were common. The overall survival rate was high (93.3%), with only one reported mortality. Toxicokinetic data showed that HD significantly reduced the elimination half-life of barium compared to non-dialysis approaches, while CRRT provided slower but sustained toxin removal. No ECT-related adverse events were reported. The findings highlight ECT as an effective method to manage severe barium poisoning symptoms. However, limited case data and publication bias indicate a need for larger comparative studies to determine optimal extracorporeal therapy strategies.
