The accuracy and advantages of determining the flow rates of opaque media in catheters used in the infant and pediatric age group is essential in obtaining proper opacification with minimum toxicity to the patient. Flow rates expressed as cubic centimeters per second and grams of iodine per second were determined by using representative standard pediatric catheters in various sizes and lengths. Three representative opaque medias were used to determine these findings. Although present-day injector pumps are frequently calibrated in delivery rates, they cannot be applied directly to the cardiac catheters usually used with infants and small children.
确定用于婴幼儿年龄组的导管中不透明介质流速的准确性和优势，对于在对患者毒性最小的情况下实现适当的造影至关重要。通过使用各种尺寸和长度的代表性标准儿科导管，确定了以立方厘米每秒和碘克每秒表示的流速。使用三种代表性的不透明介质来确定这些结果。尽管当今的注射泵经常以输送速率进行校准，但它们不能直接应用于通常用于婴幼儿的心脏导管。
