Abstract: Objective To explore the usefulness of conventional ultrasonography and contrast enhanced ultrasonography (CEUS) to identify the tip position of tunneled cuffed catheter (TCC). Methods A total of 45 patients were subjected to TCC placement under the guidance of body landmark and Seldinger’s techniques and beside real-time ultrasonography. After insertion of the catheter, conventional ultrasonography via subxiphoid cardiac view was used to observe the tip position. If the catheter tip was not visible on conventional ultrasonography, CEUS was performed to further confirm the catheter tip position. If the catheter tip was not in its target position, prompt adjustment was made. After the manipulation, a chest radiograph was made to reconfirm the tip positioning. Results Conventional ultrasonography identified the catheter tips in 77.8% (35/45) patients, and CEUS identified the tip position in the remaining 10 patients. Only 62.2% catheter tips located at the target position at the first attempt, and adjustment of the catheter tips was required in the remaining patients. Conclusions Conventional ultrasonography combined with CEUS can accurately and promptly identify the tip position of TCC. This method is safe, accurate, time-saving, convenient and free of radiation. We recommend its use following TCC insertion.
