The research project is focused on examining the clinical effectiveness of an enhanced ultrasound dynamic needle tip positioning method for guiding distal radial artery puncture and catheterization. Anticipated results suggest that the improved ultrasound dynamic needle tip positioning method will surpass tactile guidance in terms of the success rate of the first puncture attempt, as well as overall puncture and catheterization success rates.
The distal radial artery access route has several advantages; however, it comes with drawbacks like tortuous anatomy and a smaller lumen diameter. Compared to the wrist radial artery approach, it is more prone to spasm and has a lower success rate for puncture and catheterization. This clinical study aims to explore the effectiveness of an enhanced ultrasound dynamic needle tip positioning method for guiding distal radial artery puncture and catheterization. In this prospective, randomized, single-center study, we will enroll 112 patients scheduled for percutaneous coronary angiography. They will be randomly assigned to either the control group (56 cases) or the study group (56 cases) using digital odd-even randomization. The control group will undergo conventional tactile guidance, while the study group will be guided by the improved ultrasound dynamic needle tip positioning method. Parameters to be compared between the two groups include the success rate of the first puncture attempt, overall puncture success rate, number of puncture attempts, success rate of catheterization, time to successful catheterization, proportion of sheath sizes used, incidence of hematoma, and incidence of radial artery occlusion 24 hours post-procedure. The anticipated outcome is that the improved ultrasound dynamic needle tip positioning method will enhance the success rate of the first puncture attempt, overall puncture success rate, and catheterization success rate, while reducing the number of puncture attempts and operation time.

This study employs a modified ultrasound-guided dynamic needle tip positioning technique for distal radial arterial cannulation. The technique uses an ultrasound probe with two wires to create an acoustic shadow, improving needle tip visibility. Real-time dynamic tracking assists in precise needle placement within the distal radial artery through the nose-horn region. This method is used for coronary angiography and potential percutaneous coronary interventions, aiming to increase success rates and reduce complications like hematoma, nerve injury, and arterial spasm, thus enhancing safety and efficiency.
