本文对40例出生体重在1700 ~ 2500克的早产儿进行了吸吮-吞咽模式和食管动力的测定。在初次吸吮后，观察到两种类型的吸吮-吞咽模式。第一种是“未成熟的吮吸-吞咽模式”，包括每分钟1至1.5次吮吸的速率，并包括吞咽之前或之后的短暂吮吸爆发。第二种是“成熟的吮吸-吞咽模式”，其特征是连续吮吸30次以上，速度为每秒2次。在吮吸爆发期间，吞咽频繁发生。最小的早产儿在食管体部的阴茎勃起较差，直到阴茎勃起成为繁殖性的之后才达到“成熟的吸吮-吞咽模式”。据推测，“不成熟的吸吮-吞咽模式”阻止了大量液体的输送，而这些液体不能被尚未发育出足够的消化能力的食管处理。
The determination of suck-swallow patterns and esophageal motility were performed on 40 premature infants between 1,700 and 2,500 gm birth weight. After initial mouthing, two types of suck-swallow patterns were noted. The first, "the immature suck-swallow pattern" consisted of a rate of 1 to 1.5 sucks per minute and consisted of short sucking bursts preceded or followed by swallows. The second, "the mature suck-swallow pattern" was characterized by bursts of over 30 sucks, and a rate of 2 per second. Swallows occurred frequently during sucking bursts. The smallest premature infants had poor penistalsis in the body of the esophagus and did not attain a "mature suck-swallow pattern" until after peristalsis had become propagative. It is postulated that the "immature suck-swallow pattern" prevents the delivery of a large amount of fluid which could not be handled by an esophagus which has not yet developed the ability for adequate peristalsis.
