Radial Artery Catheterization, Ultrasound-guided Short-axis Out-of-plane Dynamic Approach, Ultrasound or Ultrasonography
Conditions
Brief summary
The study is designed to evaluate and validate impact factors to success and complication using ultrasound guided short-axis out-of-plane dynamic approach, and validate the impaction.
Detailed description
The study including two phase: observational phase and validation phase. In observational phase, factors relative to success catheterization without posterior puncture and success in first attempt are evaluated. In validation phase, patients are randomized into different depth group with or without injection of saline. Success without posterior wall puncture, success in first attempt and overall, catheterization time are compared between groups.
Interventions
PROCEDUREimprovement of arterial depth
deepen radial arterial depth by injection of saline to more than deep cutoff point relative to result.
