Pre-bypass ultrafiltration reduces cytokine burden of blood prime in pediatric cardiac surgery.

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
Allogeneic red blood cells (RBCs) are commonly used for cardiopulmonary bypass (CPB) circuit priming in congenital heart surgery. While convection-based pre-bypass ultrafiltration (PBUF) corrects acid-base, electrolyte, and metabolite imbalances, its efficacy in removing RBC cytokines/chemokines remains unclear. In a prospective observational study, 22 children (median age: 4.1 months) undergoing congenital heart surgery were enrolled. PBUF of RBC-primed CPB circuits was conducted using bicarbonate-buffered hemofiltration solution. Cytokines/chemokines were quantified in RBC supernatants, CPB priming (before and after PBUF), preoperative patient plasma, and PBUF effluent using Luminex-based multiplex technology. 30 of 50 cytokines were detected in > 50% of RBC supernatants. RBC priming significantly elevated concentrations of 25 cytokines, with 20 further rising after PBUF. At CPB onset, eight mediators (MIF, IL-15, CCL11/Eotaxin, CCL2/MCP-1, VEGF, IL-5, VCAM-1, ICAM-1) exceeded patient plasma concentrations. PBUF filtered cytokines with different efficiencies (0.6-97%). Despite poor filtration or increased concentrations, total mediator load of 42 cytokines decreased significantly (33.3-69.1% of pre-processing levels) after PBUF. In conclusion, PBUF effectively removed multiple cytokines/chemokines released from RBC. Beyond filtration, decrease of total mediator load may be attributed to adsorption to circuit components or rebinding to RBCs. Improved washing techniques may further optimize mediator levels in RBC-primed CPB circuits.
