Continuous high-intensity noise in the Neonatal Intensive Care Unit (NICU) is stressful for premature infants and its reduction is considered as a nursing care. This study aimed to evaluate the effects of earmuffs' use on the physiologic and motor responses of premature infants.
This is a clinical trial conducted on 64 premature infants admitted to the NICU, who met the inclusion criteria, and were randomly assigned to study and control groups. Earmuffs were used for premature infants for 2 h in the morning and 2 h in the afternoon for two consecutive days to reduce the noise intensity in the busiest time of the NICU. The group with earmuff (study group) was compared with the control group receiving only routine care. Infants' physiologic and motor responses were observed before, during, immediately, and 1 h after the intervention. Analysis of covariance and repeated measure analysis of variance (ANOVA) were used to analyze the data.
When infants wore the earmuffs, they had significantly higher mean arterial oxygen saturation, the less frequent motor response, and a decrease in their pulse and respiratory rate.
Paying attention to environmental noise can help the patients, especially the neonates in the NICU, and can be considered as a nursing care. Wearing earmuffs can protect premature infants against noise in the NICU and improve their physiological and motor state.
新生儿重症监护病房（NICU）持续的高强度噪音对早产儿来说是一种压力源，降低噪音被视为一种护理措施。本研究旨在评估使用耳罩对早产儿生理和运动反应的影响。
这是一项针对64名入住NICU且符合纳入标准的早产儿进行的临床试验，他们被随机分为研究组和对照组。连续两天，在NICU最繁忙的时段，为早产儿每天上午佩戴耳罩2小时，下午佩戴2小时，以降低噪音强度。将佩戴耳罩的组（研究组）与仅接受常规护理的对照组进行比较。在干预前、干预期间、干预后即刻以及干预后1小时观察婴儿的生理和运动反应。采用协方差分析和重复测量方差分析（ANOVA）对数据进行分析。
当婴儿佩戴耳罩时，他们的平均动脉血氧饱和度显著更高，运动反应频率更低，脉搏和呼吸频率下降。
关注环境噪音对患者有益，尤其是对NICU中的新生儿，可将其视为一种护理措施。佩戴耳罩可以保护早产儿免受NICU噪音的影响，并改善他们的生理和运动状态。
