Protocol summary

Study aim
In this study, the efficacy of combined topical gel of verapamil, nitroglycerin and lidocaine will be investigated in preventing radial artery spasm during angioplasty via radial artery.
Design
Randomized, two-blinded, parallel, placebo-controlled clinical trial with 64 patients in each group.
Settings and conduct
This two blind study will be done in Tehran Heart Center. Health care providers and patients are blind. Patients fall into two groups using block randomization. One group received placebo gel and other received therapeutic gel. The basal diameter of radial artery is measured with ultrasound. 0.5 to 1 hour before process, the therapeutic or the placebo gel are applied on the radial artery pulse, and then covered with a transparent dressing. After removing the gel, the radial artery diameter is measured with ultrasound before process beginning. During PCI, following parameters is recorded: Sedative drug and its dose, Sheath insertion in one or more attempts, Wire passage in one or more attempts, Vasodilator parenteral cocktail used, Sympathetic system response, Radial artery spasm score, Patient forearm pain. After performing PCI, radial artery is reevaluated with ultrasound.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Age older than 18 years old Radial elective PCI candidates Exclusion criteria: Hypersensitivity or contraindication to lidocaine Hypersensitivity or contraindication to nitroglycerin Baseline weak radial pulse Inadequate blood supply to palm Presence of artriovenous fistula for dialysis Pregnant women or nursing mothers
Intervention groups
Intervention group: Combined Topical Gel of Verapamil, Nitroglycerin and Lidocain will be applied before PCI. Control group: Placebo gel will be applied before PCI.
Main outcome variables
Radial artery spasm؛ Change in Radial artery diameter
