Abstract:
Background: Peripherally inserted central catheters (PICCs) are performed for medium and long term intravenous therapy. The most recent guidelines recommend the use of ultrasound-guided venipuncture to reduce surgery-related complications. In recent years, bedside ultrasound has also been used as evidence of accuracy in tip navigation and tip positioning. This paper is aimed to investigate using tip navigation with the ultrasonic technique and intracavitary electrocardiogram during the catheterization, and to suggest a feasible and safe standardized protocol for clinical practice.
Methods: A total of 1727 tumor clients who suffered from combined the ultrasonic technique with intracavitary electrocardiogram (ECG + US group) to confirm the tip location of PICC were included in Peking Union Medical College Hospital in 2020. And based on electronic medical records according to the types of cancer as 1:1 to select 1727 cases who only underwent electrocardiogram (ECG group) to verify the tip location of catheters with the same team in 2019. Compared two groups of purpose of catheter, insertion site of upper limbs, times of puncture and delivery catheters, tip location and malposition of peripherally inserted central catheter, and analysis of the safety and feasibility.
Results: There were no significant differences between the two groups in the purpose of catheter, insertion site of upper limbs, times of puncture, and delivery catheters. The percentage of optimal tip location in ECG + US group was significantly higher than that in ECG group, and the rate of malposition of catheters was obviously lower than that in ECG group (p < 0.001).
Conclusions: Tip navigation based with ultrasound and intracavitary electrocardiogram has high accuracy to confirm tip location of PICC, and it is also feasible and safe, which can not only to make up for the deficiency of patients without surface P waves who could not be applied ECG but also to fit for all patients.
