本研究旨在探讨新生儿加护病房（NICU）中，常规护理程序及噪音事件对早产儿行为及生理反应之影响。受试者是55名早产儿，体重从480到1930 g，年龄从23到37周妊娠。每5分钟记录一次NICU中常见的19项护理活动以及大声噪音，如警报、电话、大声讲话或婴儿哭声。婴儿的生理和行为反应在早上和晚上每隔5分钟记录2小时。护理干预和噪音导致婴儿的行为和生理反应发生显着变化。单独的噪音和单独的护理干预的存在导致了类似的生理反应，但是，这些事件的组合是不累积的。在12个观察期内，婴儿平均每小时改变6次行为状态，在48个4小时的观察期内，持续状态（10分钟或更长时间）的次数平均为10次。
This study documents the effects of routine nursing procedures and loud noise events on the behavioral and physiological responses of premature infants in the neonatal intensive care unit (NICU). The subjects were 55 premature infants ranging in weight from 480 to 1930 g and in age from 23 to 37 weeks gestation. Nineteen nursing activities common in the NICU as well as loud noises such as alarms, telephones, loud speech, or infant crying were recorded every 5 minutes. The infants' physiological and behavioral responses were recorded at 5-minute intervals for 2 hours in the morning and 2 hours in the evening. Nursing interventions and noise resulted in significant changes in both the behavioral and physiological responses of infants. The presence of noise alone and nursing interventions alone resulted in similar physiological responses; however, the combination of these events was not cumulative. Infants changed their behavioral states an average of six times each hour during the 12 observation periods, and the number of enduring states (10 minutes or longer) averaged 10 times in the 48 observation periods of 4 hours.
