The effect of stimulation (oral-gustatory with sucrose, tactile-bucal, and tactile-manual) on the frequency of hand contact with the oral (hand-mouth and hand sucking) and perioral (hands near the mouth) regions was compared in 24 full-term newborns. The 16-minute evaluation was divided into four equal periods, without intervals: (A) Baseline, no stimulation applied; (B) tactile-bucal, the newborn was allowed to suck the distal phalange of the researcher's little finger; (C) tactile-manual, the newborn was allowed to grasp the researcher's index finger; (D) 0.3 ml sucrose solution was administered orally to the newborns. After every three newborns were tested, the sequence of stimulation application was changed. The frequencies of the hand behaviors were calculated. It was observed that the sucrose significantly increased the frequency of hand sucking (p<0.05). Sucrose was, therefore, the most effective stimulus for eliciting the behavior of hand sucking.
在24名足月儿中,比较了刺激(用蔗糖进行口腔味觉刺激、触觉-口腔刺激和触觉-手动刺激)对其手部接触口腔(手-嘴和手吸吮)及口周(手靠近嘴)区域频率的影响。16分钟的评估分为四个相等的时间段,无间隔:(A)基线期,不施加刺激;(B)触觉-口腔刺激期,让新生儿吸吮研究人员小指的远端指骨;(C)触觉-手动刺激期,让新生儿抓握研究人员的食指;(D)给新生儿口服0.3毫升蔗糖溶液。每测试三名新生儿后,改变刺激施加顺序。计算手部行为的频率。观察到蔗糖显著增加了手吸吮的频率(p<0.05)。因此,蔗糖是引发手吸吮行为最有效的刺激物。
