Cardiac Arrest From Local Anesthetic Systemic Toxicity (LAST): A Rare Complication of Ultrasound-Guided Sternal Hematoma Block.
Article in Journal of the American College of Emergency Physicians open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Local anesthetic systemic toxicity (LAST) is a rare but serious complication of ultrasound-guided nerve and hematoma blocks, affecting the cardiovascular and central nervous systems. Clinicians performing these procedures should be aware of the possibility of LAST, recognize the early signs and symptoms, and understand the current accepted treatment. We present a case of cardiovascular collapse caused by LAST following an ultrasound-guided sternal hematoma block and discuss potential systems-based improvements to enhance the management and prevention of this life-threatening emergency. Thoracic blocks may pose a higher risk of LAST because of the close proximity to the heart, and we recommend using lower doses of local anesthetic when performing these blocks.
