An interventional study of dynamic and Regular-triangle in Vascular Access Complication, Ultrasound Therapy; Complications and Perioperative/Postoperative Complications, sponsored by Peking Union Medical College Hospital. Completed at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-09-18.
Sponsored by Peking Union Medical College Hospital · Not applicable, Interventional, and Supportive care
To assess and improve the safety and success rate of vascular puncture and catheterization using ultrasound-guided methods.
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.
59 studies on the registry are indexed under Cardiovascular Abnormalities; 14 are open to participants now.
