Application of Doppler Ultrasound in Internal Jugular Vein Catheterization: Analysis of 323 Critically Ill Patients

Objective: To investigate the application of doppler ultrasound in critically ill patients with internal jugular vein catheterization. Methods: 323 cases of anticipated difficult internal jugular vein in critically ill patients, the ultrasound guided right internal jugular vein puncture, puncture record time, a success rate of catheterization, more than twice the success rate of catheterization and complications place the number of cases. Results: 323 patients were in the ultrasound guided right internal jugular vein catheterization successfully, no case be diverted to other parts due to puncture failure of central venous puncture. Doppler ultrasound guided catheter placement operation time of 184.6 ± 20.5s. Doppler ultrasound guided puncture an 93% success rate. Doppler ultrasound guided puncture more than twice the success rate of 100%. Complication rate was 4.64%. Conclusion: Doppler ultrasound guided internal jugular vein in critically ill patients cannulated shortened tube time, reducing the number of puncture and improve the success rate of a puncture.
