Stress-coping behavior in preterm infants between 33 and 35 weeks post-conceptual age

本研究旨在探讨早产儿在出生后33 ~ 35周的压力应对行为特征。共观察并记录了6名早产儿。采用定量和定性方法对数据进行分析。结果表明：1）婴儿的应对行为是偶发性的; 2）婴儿在重复反应后，应对行为由灵活变为紧张; 3）婴儿在手臂位置变得不稳定后，应对行为减少; 4）婴儿的肌张力减弱，睡眠状态迅速下降。这些研究结果表明，有必要通过将这些婴儿保持在不限制其手臂运动的合适位置来照顾他们。

The purpose of the present study was to clarify the characteristicsof stress-coping behavior exhibited by preterm infants between 33 and 35 weeks post-conceptual age. A total of 6 premature babies were observed and video-recorded. Data were analyzed using quantitative and qualitative methods. The following 4 patterns were obtained: 1) various coping behaviors appear sporadically; 2) after repeated responses, the coping behaviors grow from flexibly performed to strained; 3) the coping behaviors decrease after arm position becomes more unsteady; and 4) infants show weakened muscle tone and rapid sleep state decline. These findings indicate that it is necessary to care for these infants by keeping them in a suitable position that does not restrict their arm movement.
