Condition patients requiring radial arterial line cannulation.
Treatments ultrasound, doppler
Sponsor University of Iowa
Start date May 2009
End date December 2011
Trial size 104 participants
Trial identifier NCT01276158, 200905711


In infants, percutaneous cannulation of radial artery requires considerable expertise. People have been using Doppler guided radial artery cannulation technique to improve success rate for more than 20 years. Recently, Ultrasound sonography has been utilized for central line placement in pediatrics. The purpose of this study is whether ultrasound guided radial artery cannulation technique improves the success rate compared to traditional doppler guided technique.
