With technological advances in NICUs the survival rate of preterm infants has been increased. Because NICU environment is a potent source of stress for infants, its modification is an essential measure to decrease infants' morbidity. The purposes of this study were to compare the effects of wearing earmuff and provision silence for infants on their motor responses and gaining weight.
In a randomized clinical trial 96 preterm infants were enrolled. Their motor responses were evaluated for two consecutive days in the morning and afternoon shifts, in the groups of earmuff and silence, and at similar time points in the control group. Also their weight was measured at days 1 and 10.
In the two intervention groups, means of motor responses in infants were significantly less than in the control group, and weight gain of infants was more than the control group. However weight gain was more pronounced in the earmuff group.
Both interventions led to decreasing number of motor responses and improvement of weight gain pattern, but these effects were more pronounced in earmuff group; thus because implementation of silence in NICUs has many barriers, it is suggested to use earmuff for preterm infants in these units. This trial obtained IRCT registration number IRCT2012092010812N2.
随着新生儿重症监护病房（NICU）技术的进步，早产儿的存活率有所提高。由于NICU环境是婴儿压力的一个重要来源，对其进行改善是降低婴儿发病率的一项重要措施。本研究的目的是比较给婴儿佩戴耳罩和保持安静对其运动反应和体重增加的影响。
在一项随机临床试验中，纳入了96名早产儿。在耳罩组和安静组，以及对照组的相似时间点，于上午和下午班次连续两天对他们的运动反应进行评估。同时在第1天和第10天测量他们的体重。
在两个干预组中，婴儿的运动反应平均值显著低于对照组，且婴儿的体重增加超过对照组。然而，耳罩组的体重增加更为明显。
两种干预措施均导致运动反应次数减少和体重增加模式改善，但这些效果在耳罩组更为明显；因此，由于在NICU保持安静存在诸多障碍，建议在这些病房为早产儿使用耳罩。本试验获得了伊朗临床试验注册中心（IRCT）注册号IRCT2012092010812N2。
