Evaluating the effect of ulnar artery compression while pressing on radial artery to stop bleeding, in maintaining radial artery potency, after cardiac catheterization through the radial artery. We prospectively plan to compare 3000 patients referred for cardiac catheterization, randomized into two groups, one group receiving radial artery compression for stopping bleeding, in a standard fashion following best practices, and the other group receiving radial artery compression using standard best practices and ulnar artery compression. Radial artery status will be evaluated in 24 hours and 30 days of the procedure to evaluate its potency, using plethysmography.

Condition Intervention Phase
Occlusion of Artery
Procedure: Ulnar artery compression
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Prevention of Radial Artery Occlusion: Prophylactic Hyperperfusion Evaluation Trial

Further study details as provided by Total Cardiovascular Solutions:

Primary Outcome Measures:
  • 30 day radial artery occlusion [ Time Frame: 30 days ]
    Evaluation of radial artery patency using plethysmography

Secondary Outcome Measures:
  • hand ischemia [ Time Frame: 2 hours ]
    evaluated by clinical evaluation for neurosensory deficit or other clinical signs of ischemia.

Enrollment: 3000
Study Start Date: January 2011
Study Completion Date: July 2015
Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Patent hemostasis
Patent hemostasis is the technique for radial artery hemostasis after transradial catheterization, with proactive attempt to maintain radial artery hemostasis and radial artery patency.
Procedure: Ulnar artery compression
Compression of ulnar artery for 2 hours with radial artery hemostasis
Active Comparator: Ulnar artery compression
Ulnar artery compression will involve radial artery hemostasis using patent hemostasis technique and compression of ulnar artery to the point of occluding flow, in an attempt to augment radial artery flow.
Procedure: Ulnar artery compression
Compression of ulnar artery for 2 hours with radial artery hemostasis
