Objective To explore the feasibility of rapid saline infusion ultrasound imaging for the assessment of the central venous catheter tip location. Methods A total of 83 critically ill adult patients with indications for central venous catheterization who were admitted to Peking University People's Hospital from July 2020 to July 2021 were selected. Cardiac ultrasonography was used to observe the turbulent flow imaging formed after rapid injection of normal saline into the central venous catheter to quickly determine the exact position of the catheter tip, and compared with the results of bedside chest X-ray to evaluate the method of rapid injection of normal saline effectiveness. Results The results of judging the position of the tip of the central venous catheter by the rapid perfusion ultrasound imaging of normal saline and bedside chest X-ray were basically consistent (Kappa=0.917, P<0.05). The rapid saline infusion ultrasound imaging had a sensitivity of 100.0%(95%CI 94.0%-100%)and specificity of 85.7%(95%CI 42.0%-99.2%). It took 77.5 (69.5, 85.5) minutes to determine the catheter position by chest X-ray, which was significantly longer than that of normal saline perfusion ultrasound imaging [6.4 (5.8, 6.9) minutes], and the difference was statistically significant (P<0.05). Conclusion The rapid saline infusion ultrasound imaging can effectively determine the tip position of the central venous catheter and the diagnosis time is shorter than that of the bedside chest X-ray examination.
