Do We Need Premedication Before Coronary Angiography? A Controlled Clinical Trial

摘要

BackgroundPremedication with benzodiazepines has been thought to reduce patient anxiety, pain perception, and non-catheter-induced coronary spasms and may increase procedure-related complications. We used to routinely provide premedication with diazepam and chlorpheniramine before cardiac catheterization procedures. However the benefits of such a treatment are not well established here. Therefore, we designed this study to test whether the routine use of premedication during coronary angiography is needed.
