Efficacy and organ protective effects of continuous renal replacement therapy in children with organic acidemia complicated by decompensated acidosis: a retrospective study in PICU.

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
backgroundMetabolic decompensation is life-threatening in children with organic acidemia (OA). This study aims to evaluate the efficacy of continuous renal replacement therapy (CRRT) in treating patients with OA complicated by decompensated metabolic acidosis in pediatric intensive care units (PICU) and to explore its impact on organ function impairment associated with this condition.
methodsData of children with OA developed decompensated metabolic acidosis admitted to PICU between 2013 and 2024 were collected and retrospectively analyzed. The patients were divided into two groups: the CRRT treatment group (admitted after 2019) and the conventional treatment group (admitted before 2019).
resultsForty-six patients were included in the study. After 24 hours of CRRT therapy, there was a significant decrease in levels of lactic acid, plasma ammonia, blood urea nitrogen, creatinine, troponin, myoglobin and neuron-specific enolase (NSE) compared to the conventional treatment group. After 48 hours of CRRT therapy, alanine aminotransferase and aspartate aminotransferase levels decreased in comparison with the conventional treatment group (p < 0.05). After 5 days of therapy, a significant decline in NSE persisted in the CRRT group compared to the conventional treatment group (p < 0.05). In the conventional group, organ injury biomarkers increased at 24 hours and gradually declined over time, whereas no elevation of these biomarkers was observed in the CRRT group. The duration of mechanical ventilation and the length of stay in the PICU were significantly shorter in the CRRT group (p < 0.05).
conclusionsIn patient with OA complicated by decompensated metabolic acidosis, the treatment combined with CRRT can efficiently remove metabolites, thereby avoid neuron and the major organs from further injury. Application of CRRT can help these patients recover earlier from the metabolic crisis.
