In this study, eligible subjects were randomly assigned to the experimental or control group through randomization (1:1). Under the guidance of electrocardiographic Doppler ultrasound guided puncture and catheterization (EDUG) technology, the tunnel puncture method was compared with the conventional puncture method. The two groups of patients were observed and evaluated intraoperative and postoperative 7 ± 3 days, 30 ± 7 days, 60 ± 10 days, and 90 ± 10 days 120 ± 10 days (if any) and the occurrence of complications during extubation or unplanned extubation at the end of treatment, comparing cases in the north and south, as well as complications related to different catheterization methods

This study was designed as a prospective, multicenter, randomized controlled study, with the incidence of postoperative complications as the main observation end point. It was a superiority design.The purpose of this study was to compare the incidence of complications associated with EDUG-guided subcutaneous tunneling and conventional puncture after peripheral vein placement of PICCs

This study was a prospective, multicenter, randomized controlled study. The study aimed to exploring the influence of PICC intra catheter guide wire or PICC conductive tip as intra luminal electrode on the positioning accuracy of catheter tip and exploring the influence of PICC intra catheter guide wire or PICC conductive tip as intra luminal electrode on catheterization complications.
