Randomized Clinical Trial Comparing Transradial Catheterization With or Without Spasmolytic Drugs
Randomized Clinical Trial Comparing Transradial Catheterization With or Without Spasmolytic Drugs
Single-center study, randomized, double-blind, placebo controlled, with patients undergoing
 diagnostic or therapeutic catheterization via the transradial approach. Patients will be
 randomized into two groups: one group will receive the vasodilator nitroglycerin during the
 procedure (intervention group), and a second group will receive saline 0.9% in the same
 volume and time during the procedure (control group).

 Will be evaluated: incidence of spasms of the radial artery, ability to perform the procedure
 without the need to change the access site, pain presented by the patient, time and total
 radiation of the procedure.
Inclusion Criteria:

 -  Indication for cardiac catheterization

 -  Suitable candidates for transradial approach

 Exclusion Criteria:

 -  AMI

 -  Intubated patients

 -  Complications during procedure (cardiac arrest, pulmonary edema, cardiogenic shock,
 stroke)

 -  Prior inclusion in this trial
