Description
Kui Mao and colleagues pool randomized trials of a moving needle-tip method for placing wrist artery lines under ultrasound in a 2026 meta-analysis. Short-axis views center the vessel well but lose sight of the needle tip, risking failed first tries.
Five databases were searched through January 2026, and thirteen trials with 1,482 adults qualified. Overall first-try success matched the long-axis view across methods. Splitting by technique told another story: the dynamic tip method beat both the fixed short-axis habit and the long-axis view. Time, bruising, wall punctures, and vessel spasm were also compared across trials.
