Amplitude-Integrated/Continuous Electroencephalography for Early Detection of Low Cardiac Output After Chest Closure in an Infant.
Article in JACC. Case reports, 2025. 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
backgroundWeaning from cardiopulmonary bypass in pediatric cardiac surgery is challenging, especially after prolonged procedures. Delayed chest closure may be necessary in cases of low cardiac output syndrome (LCOS) to support hemodynamic recovery. Although near-infrared spectroscopy is standard for neuromonitoring, amplitude-integrated electroencephalography (aEEG) and continuous electroencephalography (cEEG) are emerging tools. CASE SUMMARY: We report the case of a 6-month-old infant with transposition of the great arteries who required delayed chest closure after surgical repair. LCOS recurred after chest closure on postoperative day 3 despite stable near-infrared spectroscopy values. Retrospective aEEG/cEEG analysis, unintentionally initiated before closure, showed early EEG abnormalities preceding clinical signs, which were resolved after chest reopening. DISCUSSION: This case highlights the potential of aEEG/cEEG to detect early cerebral compromise due to LCOS, even when conventional monitoring appears normal, an association not well established in the literature. TAKE-HOME MESSAGE: Cerebral distress may be detected earlier with aEEG compared with standard monitoring, supporting timely LCOS identification and management.
