Topical Radial Artery Vasodilation

Phase 2/3 Completed 86 enrolled University of California, San Francisco

RandomizedParallel-groupQuadruple-blindTreatment

Summary

The aim of the study is to facilitate radial artery access for cardiac catheterization. The investigators hypothesize that topical nitroglycerin and lidocaine will reduce radial artery spasm. Patients undergoing cardiac catheterization via the radial artery will be randomized to topical nitroglycerin + lidocaine versus placebo.
