Effect of Subcutaneous Nitroglycerin on the Prevention of Radial Artery Occlusion After Radial Artery Catheterization in Pediatric Patients - a Prospective Randomized Controlled Trial

H-2206-070-1332

The primary objective of the study is to evaluate the vasodilative effect of subcutaneous nitroglycerin to prevent radial arterial occlusion(RAO) after removal of the radial arterial catheter in pediatric patients. The hypothesis of this study is that subcutaneous nitroglycerin will decrease the incidence of radial arterial occlusion after radial arterial catheter removal in pediatric patients by increasing the radial artery size and improving the first-attempt success rate of radial artery cannulation. This is a single-center, double-blind, randomized, placebo-controlled study comparing the effect of subcutaneous nitroglycerin and saline on radial artery cannulation and catheter removal in pediatric patients. Prior to the procedure, each patient will be randomized into either the control arm, saline, or the study arm, nitroglycerin.
