Abstract:
Peripherally inserted central catheter (PICC) has the advantages of long-term indwelling, avoiding repeated puncture and effectively protecting peripheral blood vessels, and has been widely used in various clinical fields. The correct position of the PICC tip is an important guarantee for the safe use of catheter. If malposition occurs, it will shorten the catheter indwelling time, increase the incidence of complications, and even life-threatening in severe cases. This article summarizes the methods of PICC tip positioning and the related factors of malposition. In this article, in addition to conventional positioning methods, new positioning techniques such as Sherlock 3CG tip confirmation system and VasoNova vascular positioning system (VPS) combined with electrocardiogram (ECG) are proposed. This article points out that factors such as vascular factors, respiratory motion and intrathoracic pressure changes can lead to changes in the position of the PICC tip, in order to provide a reference for clinical medical and nursing staff to determine the position of the catheter tip and prevent catheter tip malposition.
