Application of ultrasound in rapid position detection of central venous catheterization

Abstract

Objective To explore the application effect of ultrasound in rapid position detection of central venous catheterization.Methods Totals of 218 patients received central venous catheterization were randomly divided into experimental group ( 114 cases) and control group ( 104 cases).The experimental group accepted ultrasonic testing before PICC catheter was fixed and examined by X-ray.The control group accepted traditional examination after catheter was fixed.The accuracy of catheterization position,patients' satisfaction,catheterization time,catheter detective costs,and ratio of catheter-adjusting related complications among both groups were collected and analysed.Results The rate of correct catheter positioning in the first time in experimental group was 96.49％ higher than control group which was 76.92％,and the difference was statistically significant ( x2 =18.603,P ＜0.01 ).Patients satisfaction score of experimental group was(4.717 ±0.524) higher than control group that was (4.096 ± 1.296 ).Catheterization time of experimental group was (21.455 ± 3.923 )min lower than control group (24.123 ± 7.184 )min,and the difference was statistically significant ( t =4.728,- 4.603,respectively; P ＜ 0.05 ).The rate of catheter-adjusting-related complications of experimental group was 18.421％ lower than 30.769％ in control group,and the difference was statistically significant ( x2 =4.507,P ＜ 0.05 ). There was no significantly difference between two groups in catheter detective costs.Conclusions Application of ultrasound in rapid position detection of central venous catheterization can increase the accuracy of catheterization,save catheterization time,reduce the ratio of catheteradjusting related complications,effectively improve the quality of PICC without increase catheterization costs.
