Study 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.
Primary Outcome
The cross-sectional radial artery area was measured using a high frequency linear array transducer. All ultrasound measurements were made 2 cm proximal to the radial styloid process. Each measurement was performed 3 times and averaged. At least 30 minutes after the application of topical creams, the radial artery diameter was again measured in the same fashion.
Interventions
- OTHER Placebo
- DRUG Nitroglycerin and lidocaine
