Exploratory research on Wiguide needle guidance ultrasound technology for radial artery puncture

Abstract

Objective To investigate the clinical significance of Wiguide needle guidance ultrasound technology in radial artery puncture. Methods One hundred and thirty-five patients who would receive elective surgery requiring radial artery puncture and catheterization to monitor invasive blood pressure were randomly divided into 3 groups(n=45): blind puncture group(group A), ultrasound puncture group(group B) and Wiguide needle guidance ultrasound puncture group(group C). The diameter and depth of radial artery, blood return time, puncture time for the process and the puncture success rate were recorded and compared. Results There was significant diffeence in the blood return time among three groups (P=0.039), the blood return time in group B was higher than in group A and C (P=0.029, 0.027). The difference was statistically significant in the puncture time among three groups (P=0.002), the puncture time in group B was higher than in group A and C (P=0.009, 0.001). The puncture success rate in group A was 71.11%, the puncture success rate were 100% in both group B and C. Conclusions Wiguide needle guidance ultrasound technology could effectively improve the skill of vascular puncture, which shortens the puncture time and improves the success rate of puncture. Wiguide needle guidance ultrasound technology provides benefits to master the ultrasound-guided vascular puncture for clinical work.
