目的探讨获得和利用客观措施的时间和位移从videofluorescence performed in pediatrics.Study设计的儿童（n = 121;平均年龄38个月，范围9天-21岁，SD 4岁）被称为videofluorescence招募。所有人都接受了标准化的协议，包括以每秒25帧记录的20秒循环。视频进行了分析，使用客观的数字措施的时间和位移。结果所有儿童均获得了定量测量结果。咽食管段的最大开口和时间测量与年龄的增加相关。数值与经验证的成人数据一致。平均辐射时间为1.58分钟（范围0.15-3.47，SD 0.66），平均辐射剂量为30.16 cGycm（2）（范围6.5-85 SD 15.17）。辐射剂量（P = 0.21）和辐射时间（P = 0.72）没有显着不同的使用帧速率增加相比，年龄匹配的队列（n = 100）之前，协议changes.Conclusions吞咽测量的客观定量措施，可以成功地从儿科视频透视进行高帧速率，而不增加辐射剂量。措施是生物学上一致的，可重复的，表现出内部交叉相关性，并反映成人数据。这些措施有可能支持有针对性的管理和客观的监测变化的儿科喂养队在未来。
Objective To investigate the feasibility of obtaining and utilizing objective measures of timing and displacement from videofluoroscopy performed in pediatrics.Study design Children (n = 121; mean age 38 months, range 9 days-21 years, SD 4 years) referred for videofluoroscopy were recruited. All underwent a standardized protocol including a mid-feed 20-second loop recorded at 25 frames per second. Videos were analyzed using objective digital measures of timing and displacement. Radiation dose was recorded.Results Quantitative measures were obtained in all children. Maximum opening of the pharyngoesophageal segment and timing measures were correlated with increasing age. Values were congruent with validated adult data. Mean radiation time was 1.58 minutes (range 0.15-3.47, SD 0.66), and mean radiation dose was 30.16 cGycm(2) (range 6.5-85 SD 15.17). Radiation dose (P = .21) and radiation time (P = .72) were not significantly different using the increased frame rate compared with an age-matched cohort (n = 100) prior to protocol change.Conclusions Objective quantitative measures of swallowing measurements can be obtained successfully from pediatric videofluoroscopy performed at high frame rates, without increasing radiation dose. Measures are biologically consistent, reproducible, demonstrate internal cross-correlation, and mirror adult data. These measures have potential to support targeted management and objective monitoring of change by pediatric feeding teams in the future.
