AIM: Radial @entity2553 is common during transradial procedures and is the most common cause of procedural failure. The objectives of this study were to assess whether the routine administration of sedation at the beginning of transradial coronary angiography with the use of hydrophilic-coated and smaller sheaths/catheters would reduce the incidence of @entity2553 . @entity1 AND METHODS: @entity1 undergoing transradial coronary angiography were prospectively randomized to receive @entity1363 during the procedure or no sedative treatment. The primary endpoint was angiographically confirmed @entity2553 . Stenosis of the radial artery was measured with a computer-assisted quantification method. RESULTS: In all, 150 @entity1 were randomized into a treatment group and a control group. @entity2473 occurred in 15 @entity1 of the treatment group (20   %) versus 16 in the control group (21.3   %). There were no differences between the two groups regarding the incidence of @entity2473 and the distribution of @entity2473 severity (p   >   0.05). No significant differences were observed between the two groups in terms of 30-day mortality or repeat hospitalization for any cause (p   >   0.05). CONCLUSION: Routine use of @entity1363 could not reduce the occurrence of @entity2553 during transradial coronary angiography.
