Homemade phantoms improve ultrasound-guided vein cannulation confidence and procedural performance on patients.

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
backgroundUltrasound-guided vein cannulation is an essential skill in emergency medicine. Prohibitive costs of commercial ultrasound phantoms limit the ability to adequately train residents. We assess the clinical utility of homemade phantoms for medical education.
methodsEighteen emergency medicine residents each performed 10 ultrasound-guided IV attempts on patients, half of the attempts before and half after a training course using two homemade ultrasound phantoms with 14 total Penrose drains. We conducted a prospective feasibility study using pre- and post-training surveys comparing confidence and success rates of IV cannulation attempts on patients.
resultsResidents demonstrated an improvement in successful ultrasound-guided peripheral vein cannulations from an average of 47.8% during the first five attempts to 71.1% in the last five attempts. No benefit was noted from the first to the fifth attempts, nor from the six to the tenth attempts, suggesting minimal benefit from experience early on. Residents reported increased confidence in performing ultrasound-guided venous cannulation on patients, identifying the correct probe, adjusting gain and depth, visualizing veins in short and long axis, differentiating arteries from veins, and vein cannulation on a phantom model.
conclusionHomemade ultrasound phantoms are cost effective, increase confidence, and improve emergency medicine residents' ability to perform ultrasound-guided vein cannulation.
