Primary Outcome Measures:
  • The primary object is to compare the first attempt success rate between each group. [ Time Frame: 10 minutes ]

Secondary Outcome Measures:
  • As a secondary object, a comparison will be made between groups for overall Success rate within a 10 minute time period. [ Time Frame: 10 minutes ]

Enrollment: 104
Actual Study Start Date: May 2011
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Ultrasound
Arterial line placed with Ultrasound guidance.
Procedure: Ultrasound
Ultrasound used to place arterial line
Active Comparator: Doppler
Arterial line placed with doppler guidance
Procedure: Doppler
Doppler used to place arterial line

Detailed Description:
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.
