Ultrasound-Guided Vascular Puncture and Catheterization

Not Applicable

Completed

• Conditions: Cardiovascular Abnormalities; Vascular Access Complication; Ultrasound Therapy; Complications; Perioperative/Postoperative Complications
• Interventions: Behavioral: Regular-triangle; Behavioral: dynamic

• Registration Number: NCT03656978
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

To assess and improve the safety and success rate of vascular puncture and catheterization using ultrasound-guided methods.

Detailed Description

Investigators hypothesized that （1） various ultrasound-guided methods had different performances of vascular puncture and catheterization, (2) certain risk factors influenced safety and success rate of vascular puncture and catheterization (3) implementation of protocols could improve the performances of ultrasound-guided vascular puncture and catheterization.
