降低新生兒加護病房噪音分貝率

Reduce Noise Decibel Rate In the Newborn Intensive Care Unit

單位護理主管常接到家屬抱怨新生兒加護病房內的聲音過大，嚴重干擾新生兒的睡眠與休息。本專案的目的在於降低新生兒加護病房噪音分貝率，經由現況調查分析，以測量噪音來源、噪音發生原因、噪音量等，發現新生兒加護病房內機械及人為的噪音皆達到75分貝以上。在確立了噪音干擾問題，並經文獻查證及小組討論後，擬定之改善方案為：一、加強工作車的保養，制定保養規則；二、適時調整監測儀器警示聲的音量；三、放在保溫箱上方及工作車內放置隔音泡棉吸音以降低噪音；四、實施單位護理人員在職教育。在方案實行後，結果顯示新生兒加護病房內機械性噪音平均為64.04分貝，人為噪音平均為67.9分貝。雖然本專案的目標設定在平均噪音不超過70分貝，改善後也呈現有效結果，但本著持續改善品質的理念，本專案仍持續監測及適時修正中。

The nursing manager are complained from family of the newborn intensive care unit (NICU) about the massive noise very often, which disturbs the NICU newborn's sleep and rest seriously, This special case is aimed to reduce the noise decibel rate in the NICU. By the way of analyzing current situation, we measure the source, cause and volume of noise, and found the machinery and the artificial noise in the NICU was all achieved above 75 decibels. Thus, as we established the noise disturbance factors, via literature review and the group discussion, we drew up a plan as follows: First, strengthen the maintenance of the working vehicle, and formulate a maintaining protocol; Second, adjust the alarm’s volume of every monitoring machine under the acceptable range; Third, put sound-isolated soaks upon the incubator and inside the working vehicle to reduce the noise; Fourth, develop nursing staff’s education and training. The outcome demonstrated that the average of machinery noise was 64.04 decibels, and the average artificial noise was 67.9 decibels. The goal of this hypothesis was set on 70 decibel on average. We did have an improvement after those changes. However, based on the conviction of quality improvement, we will be continuing monitor and adjust our policy to make a better outcome.
