The aim of this study was to provide a more detailed analysis of the infant's behavioural sequence that begins immediately after birth and terminates with grasping the nipple, suckling and then falling asleep.
Twenty-eight full-term infants were videotaped immediately after birth. A video protocol was developed to examine infant behaviours identified from five random videotapes.
When birth crying had stopped, the babies showed a short period of relaxation and then successively became alert. They went through an 'awakening phase', an 'active phase' with movements of limbs, rooting activity and looking at the mother's face, a 'crawling phase' with soliciting sounds, a 'familiarization phase' with licking of the areola, and a 'suckling phase' and last a 'sleeping phase'. Five factors related to the time spent to locate the breast: more number of looks at the breast 10-20 min after birth (p < 0.0001); and exposure to meperidine (p = 0.0006) related to increased time. Early start of crawling (p = 0,0040); increased number of 'soliciting sounds' (p = 0.0022); and performing hand-breast-mouth movements (p = 0.0105) related to shorter time.
Inborn breastfeeding reflexes were depressed at birth, possibly because of a depressed sensory system. It is hypothesized that when the infant is given the option to peacefully go through the nine behavioural phases birth cry, relaxation, awakening, activity, crawling, resting, familiarization, suckling and sleeping when skin-to-skin with its mother this results in early optimal self-regulation.
本研究旨在更详细地分析婴儿出生后立即开始并以抓住乳头、吮吸然后入睡为终点的行为序列。
对 28 名足月婴儿进行出生后录像。制定了一个视频方案来检查从五段随机录像中识别出的婴儿行为。
出生啼哭停止后,婴儿先短暂放松,然后逐渐变得警觉。他们经历了一个“觉醒阶段”、一个伴有四肢运动、寻乳活动和看母亲脸的“活跃阶段”、一个伴有求食声的“爬行阶段”、一个伴有乳晕舔舐的“熟悉阶段”,以及一个“吮吸阶段”,最后是“睡眠阶段”。有五个因素与寻找乳房的时间有关:出生后 10-20 分钟看乳房的次数越多(p<0.0001);接受哌替啶(p=0.0006)与时间延长有关。早期开始爬行(p=0.0040);“求食声”增多(p=0.0022);以及手-乳房-口的运动(p=0.0105)与时间缩短有关。
出生时的母乳喂养反射被抑制,可能是因为感觉系统受到抑制。假设当婴儿有机会在与母亲进行皮肤接触时,平静地经历九个行为阶段(出生啼哭、放松、觉醒、活动、爬行、休息、熟悉、吮吸和睡眠)时,这会导致早期的最佳自我调节。
