Use of a photoacoustic needle improves needle tip recognition in a video recording of simulated ultrasound-guided vascular access:

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
backgroundWe developed a novel photoacoustic needle, which emits ultrasound produced by the photoacoustic effect. This study focused on the most common "pitfall" associated with placement during ultrasound-guided vascular access, which is misidentification of the needle tip.
methodsThe study was conducted as a prospective cohort study using a questionnaire. The authors intentionally created two successful and one failed ultrasound-guided central venous catheterization videos using the photoacoustic needle on a simulator. Each of these three videos was then split into two movies for viewing, one with standard ultrasound images only and the second including the images from the photoacoustic needle, for a total of six movies.
resultsParticipants who were 18 anesthesiologists, 12 residents, and 10 medical students, watched each of the six movies and completed a survey whether the puncture was successful or not. In the results, there was a significant difference in the percentage of correct answers whether the movie depicted successful or failed puncture with and without the photoacoustic ultrasound (
conclusionThe novel photoacoustic needle improved the ability to identify the needle tip on recorded videos. It may have efficacy to prevent serious mechanical complication during the ultrasound-guided vascular access in clinical practice.
