About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • requirement of radial arterial catheterization during perioperative period
  • within cardiac-vascular disease
  • written consent

Exclusion criteria

  • contraindication to radial arterial catheterization
  • abnormal artery evaluated by ultrasonography

Treatment and study plan

improvement of arterial depth

Procedure

deepen radial arterial depth by injection of saline to more than deep cutoff point relative to result.
