简要总结
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.

Topical dilator
干预措施: Nitroglycerin and lidocaine (Drug)
结局指标
主要结局
Change in Radial Artery Diameter
时间窗: Baseline and after 30 minutes of drug application
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.
次要结局
- Radial Artery Spasm During Catheterization(2 hours)
- Radial Artery Patency(24 hours)
