The purposes of the present study are to devise the standardization of measuring the swallowing pressure and to clarify the diagnostic values of this method in case of dysphagia. The swallowing pressure measured using a micro-tip pressure transducer and the elctromyograms recorded from the suprahyoidal muscles were digitalized through an A/D converter and were fed into floppy discs. The data stored in the discs were reproduced on a CRO through a personal computer and various parameters were calculated using a self-made program. The normal ranges of the following three parameters were investigated: the swallowing pressure curve, the conduction velocity of swallowing pressure and the duration of relaxation of the upper high pressure zone of the esophagus (UHPZ). The swallowing pressure curve was obtained by connecting the peaks of the pressure in the pharyngeal and esophageal cavities. The patients with a slight degree of dysphagia showed the increase of the swallowing pressure and, on t … More he other hand, the patients with a moderate or severe degree of dysphagia showed the decrease of the pressure. To visualize normal or abnormal patterns of conduction of the swallowing pressure, the conduction curve of the swallowing pressure was proposed. In this curve, the abscissa expressed the timing of the peak of the swallowing pressure and the ordinate the distance from the naris. The curve was an S-like figure in normal subjects, since the conduction velocity was relatively slow at the velopharyngeal part, rapid at the meso- and hypo-pharyngies and slow at the esophageal orifice. When the conduction curve was deviated from the normal pattern, a disorder of the central deglutitatory system was suggested. The intraluminal pressure at UHPZ in deglutition remained at the level of atmospheric pressure for longer than 500 msec. When this duration was shorter than 500 msec, an incomplete relaxation of the esophageal orifice was suggested. In conclusion, the measurement of the swallowing pressure could offer quantitative and qualitative evaluations of swallowing function and, in addition, the choice of treatment method was feasible by analyzing the above three parameters.

本研究的目的是设计测量吞咽压力的标准化，并在吞咽困难的情况下阐明该方法的诊断值。使用微尖压力传感器和从甲状腺肌肌肉记录的大尖压传感器测量的吞咽压力通过A/D转换器进行了数字化数字化，并被送入软盘中。通过个人计算机在CRO上复制了存储在光盘中的数据，并使用自制程序计算了各种参数。研究了以下三个参数的正常范围：吞咽压力曲线，吞咽压力的传导速度和食管上高压区（UHPZ）的上高压区的松弛持续时间。通过连接咽和食管腔中的压力峰来获得吞咽压力曲线。吞咽困难程度略微的患者表明吞咽压力的增加，而在另一方面，患有中度或严重程度吞咽困难的患者表明压力降低。为了可视化吞咽压力传导的正常或异常模式，提出了吞咽压力的传导曲线。在这条曲线中，横坐标表达了吞咽压力峰的时机和距离纳里斯的距离。该曲线是正常受试者的S样曲线，因为在咽咽部分的传导速度相对较慢，在中咽和性咽中快速，并且在食管孔口速度较慢。当传导曲线偏离正常模式时，提出了中央脱水系统的疾病。在脱水中，UHPZ的腔内压力在大气压水平上保持超过500毫秒。当此持续时间短于500毫秒时，建议食管孔口不完整。结论，吞咽压力的测量可以提供吞咽功能的定量和定性评估，此外，通过分析上述三个参数，可以选择治疗方法的选择。较少的
