To determine the safety of a developmental intervention for use with preterm infants and feasibility of a time sampling procedure.
An experimental design was used to test an intervention with clinically stable 33-34-week postconceptional age infants over a 4-day period. Repeated outcome measures included pulse rate, oxygen saturation levels, and infant behavioral state.
The intervention resulted in significant differences in infant behavioral state with the experimental group achieving more alertness. Physiologic parameters remained within normal limits both during and after the intervention.
The protocol was found to be safe for implementation with clinically stable preterm infants. Behavioral state findings suggest the potential for the intervention to promote alertness. Results suggest that changes in oxygen saturation and pulse rate were dependent upon changes in behavioral state.
确定一种用于早产儿的发育干预措施的安全性以及时间抽样程序的可行性。
采用实验设计，在4天时间内对孕龄33 - 34周且临床状况稳定的婴儿进行干预测试。重复的结果测量包括心率、血氧饱和度水平和婴儿行为状态。
干预导致婴儿行为状态出现显著差异，实验组表现出更高的警觉性。干预期间及之后生理参数均保持在正常范围内。
该方案被发现对临床状况稳定的早产儿实施是安全的。行为状态结果表明该干预措施具有促进警觉性的潜力。结果表明血氧饱和度和心率的变化取决于行为状态的变化。
