Randomized Controlled TrialFacilitation of radial artery cannulation by periradial subcutaneous administration of nitroglycerin.
To determine whether subcutaneous administration of nitroglycerin mixed with local anesthetic agent results in effective vasodilation of the radial artery, and whether this technique improves access time and decreases complications. ⋯ Subcutaneous administration of nitroglycerin significantly increased radial artery diameter, which can lead to facilitation of catheterization of the radial artery for arteriography and interventions.
