Dynamic physiologic and psychological changes occur in patients awaiting excretory urography. A total of 2,000 patients were studied to see if rates of reaction to urographic contrast materials are influenced by the time of day such injections are given. Examinations performed between 7:00 A.M. and 2:00 P.M. were evaluated. The data suggest that reactions to radiographic contrast medium occur randomly and that a "safe" or "safer" time of day cannot be defined.
等待排泄性尿路造影的患者会出现动态的生理和心理变化。共对2000名患者进行了研究,以观察尿路造影剂的反应率是否受注射时间的影响。对上午7点至下午2点之间进行的检查进行了评估。数据表明,对放射造影剂的反应是随机发生的,无法确定一天中“安全”或“更安全”的时间。
