Training with ultrasound-guided puncture simulator of arteriovenous fistula for hemodialysis: experience from a center of excellence in Pará, Brazil.

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
Background: Arteriovenous fistulas (AVF) and arteriovenous grafts are important arteriovenous accesses (AVA) for patients who need hemodialysis. However, in approximately 20 to 40% of AVFs, professionals fail to successfully cannulate a new AVA for consistent use. Therefore, the ability to perform ultrasound-guided puncture is a necessary skill, particularly for accesses classified as 'difficult'. However, only a minority of nursing professionals consider themselves capable of handling ultrasound. Therefore, simulated practice environments can enable trainees to develop the skills and dexterity needed to simultaneously handle the ultrasound probe and insert the needle. Objectives: The object of this study was to analyze the effects of training with an ultrasound-guided arteriovenous fistula access simulator at a center of excellence in Belém, PA, Brazil. Methods: This analytical intervention study assessed a nursing team (17 nurses) before and after training in ultrasound-guided puncture using a simulator model comprising a chicken breast and a latex balloon, chosen because of its low cost and high fidelity. Training was carried out on January 26th and 27th, 2024, at the Fundação Hospital de Clínicas Gaspar Vianna. Results: After training with a simulator, participants' performance improved in all analyzed variables, with statistical significance differences. Furthermore, they rated the model as a good simulation of reality and as important for professional training and reported feeling more confident after training. Conclusions: Training with the ultrasound-guided puncture simulator positively influenced the performance of hemodialysis professionals.
