The effect of a traditional (Mexican Hat) and of a new (Thin Latex) nipple shield on the sucking patterns and milk intake of 5-8-day-old babies was examined. Milk intake was determined accurately by test weighing using a Sartorius electronic balance with animal weighing keyboard, and sucking patterns by filming the mouth of the baby. The Mexican Hat reduced milk transfer by 58% (P is less than 0.01), and increased sucking rate (P is less than 0.05) and time spent resting (P is less than 0.01). The Thin Latex nipple shield reduced milk intake by a smaller amount (22%), and had no significant effect on sucking patterns.
研究了传统（墨西哥帽式）和新型（薄乳胶）乳头罩对5至8日龄婴儿吸吮模式和奶量摄入的影响。使用配备动物称重键盘的赛多利斯电子天平通过测试称重精确测定奶量摄入，并通过拍摄婴儿口腔来确定吸吮模式。墨西哥帽式乳头罩使奶量转移减少了58%（P<0.01），并提高了吸吮频率（P<0.05）和休息时间（P<0.01）。薄乳胶乳头罩使奶量摄入减少的幅度较小（22%），并且对吸吮模式没有显著影响。
