Palpation versus Ultrasound-Guided Dynamic Needle Tip Positioning Technique for Radial Artery Cannulation.
Trial report in Annals of cardiac anaesthesia, 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
introductionInvasive blood pressure monitoring is the clinical reference during perioperative patient management. It is usually performed by cannulating the radial artery. Different clinical conditions make arterial cannulation difficult using the conventional palpation (CP) method. This study compares the ultrasonography (USG)-guided dynamic needle tip positioning (DNTP) technique with the CP method to assess the first-pass success rate of radial artery cannulation.
methodsIn the operation theater of a university hospital, a total of 52 adult patients requiring arterial cannulation were randomized into two equal groups. Arterial cannulation was performed using the CP method in one group and the ultrasound-guided DNTP method in the other group. The first-pass success rate was the primary objective. The 5-minute success rate, the time required for successful cannulation, the number of skin punctures, and the number of cannulae used were also compared using the Chi-square test, an independent sample t-test, and the Mann-Whitney U test.
resultsThe first-pass success rate was significantly higher in the USG-guided DNTP method (88.5%) compared to the CP method (46.2%) (P 0.001). The overall 5-minute success rate was 96.2% in the USG-guided DNTP and 65.4% (P 0.005) in the CP method. The median time for successful cannulation was significantly lesser in the USG-guided DNTP group [44 s (IQR: 35-72)] compared to the CP group [134 s (IQR: 28-378)] (P 0.007). The mean number of skin punctures in the USG-guided DNTP group was 1.15 ± 0.46 and 2.04 ± 1.18 in the CP group (P 0.001).
conclusionUSG-guided DNTP method of radial artery cannulation increased the first-pass success rate.
