Color Doppler ultrasound guided puncture in peripherally inserted central catheters / 中国医学影像技术

ABSTRACT

Objective To assess the clinical application value of color Doppler ultrasound guided puncture in peripherally inserted central catheter (PICC). Methods Thirty-two patients needed long-term intravenous infusion underwent PICC. Color Doppler ultrasound was used to select the puncture vascular,the best puncture point and angle, and the entire process was monitored and guided dynamically, and the initial position of the catheter tip was located. Results Color Doppler ultrasound-guided puncture was successful in all 32 patients, and the successful rate was 100%. The guided puncture time was 22 s to 19 min, and the first puncture succeeded in 30 patients (93.75%). Conclusion Color Doppler ultrasound-guided puncture in PICC can obviously raise the success rate of puncture, shorten puncture time and reduce the complications. It is an easy, safe and certain method.
