Groups2
Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Study | 40 mg of topical lidocaine and 30 mg of topical nitroglycerine is applied to the wrist overlying radial pulse (centered approximately 1 inch proximal to the radial styloid process) at least 60 minutes before arterial puncture. Immediately prior to sterile preparation of access site, transdermal preparation will be removed in the cath lab.~Topical Nitroglycerine: Topical nitroglycerine is applied to wrist prior to transradial cardiac catheterization to dilate radial artery and reduce spasm in study arm patients~Topical Lidocaine: Topical Lidocaine is applied to wrist prior to transradial cardiac catheterization in both study and control arms | 0 | 48 | OG000 |
| Group 2 | Control | 40 mg of topical lidocaine and placebo is applied to the wrist overlying radial pulse (centered approximately 1 inch proximal to the radial styloid process) at least 60 minutes before arterial puncture. Immediately prior to sterile preparation of access site, transdermal preparation will be removed in the cath lab.~Topical Lidocaine: Topical Lidocaine is applied to wrist prior to transradial cardiac catheterization in both study and control arms | 4 | 52 | OG001 |
