Exploratory research on Wiguide needle guidance ultrasound technology for radial artery puncture / 中华超声影像学杂志

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 ) . T he diameter and depth of radial artery ,blood return time ,puncture time for the process and the puncture success rate were recorded and compared . Results T here 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 ) . T he 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) . T he 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 .
