本文报道了用一种新的仪器(吸力计)和数据采集/分析系统(Suck Editor)对91名正常足月儿的10个营养吸吮行为参数进行了定量测量。评估的吸力参数包括吸力次数、吸力平均压力幅度、每秒平均吸力频率、平均吸力间隔(以秒为单位)、吸力幅度变异性、吸力间隔变异性、吸力突发数、平均吸力突起数、平均吸力突起持续时间和平均突起间隙持续时间。为了进行分析，测试会话被分成4 x 2分钟的片段。在单项研究测试中，在6对2分钟时间间隔的10个参数的60个可能比较中，有36个显示p值为0.05或更小。在15个不同年龄的同一婴儿的配对测试中，在五个时间间隔的十个参数的50个可能的比较中，有33个显示p值为0.05或更小。营养吸吮的量化是可行的，显示了在饲料过程中随年龄变化的十个参数的统计有效结果。这些发现表明，基于我们的方法的进一步研究可能在喂养评估、诊断和临床管理方面显示出临床价值。
We report quantitative measurements of ten parameters of nutritive sucking behavior in 91 normal full-term infants obtained using a novel device (an Orometer) and a data collection/analytical system (Suck Editor). The sucking parameters assessed include the number of sucks, mean pressure amplitude of sucks, mean frequency of sucks per second, mean suck interval in seconds, sucking amplitude variability, suck interval variability, number of suck bursts, mean number of sucks per suck burst, mean suck burst duration, and mean interburst gap duration. For analyses, test sessions were divided into 4 x 2-min segments. In single-study tests, 36 of 60 possible comparisons of ten parameters over six pairs of 2-min time intervals showed a p value of 0.05 or less. In 15 paired tests in the same infants at different ages, 33 of 50 possible comparisons of ten parameters over five time intervals showed p values of 0.05 or less. Quantification of nutritive sucking is feasible, showing statistically valid results for ten parameters that change during a feed and with age. These findings suggest that further research, based on our approach, may show clinical value in feeding assessment, diagnosis, and clinical management.
