摘要

背景。噪声是新生儿重症监护病房(NICU)中一种已知的环境应激源,由于早产儿中枢神经系统的独特脆弱性和生理不成熟,噪声可能对其产生不利影响。目标。调查南非夸祖鲁-纳塔尔省eThekwini区公共部门新生儿重症监护室的噪音水平。方法。采用分析性观察性研究设计,对公立医院进行有目的抽样。4个新生儿重症监护病房连续2天(周日和周一),在中心位置用声级计连续测量48小时的噪声。通过直接观察和使用三分之一倍频带的频谱分析,确定了噪声源样本及其发生频率。数据分析采用描述性和推断性统计。结果。这项研究包括埃德克温尼区的一家三级医院和三家区域医院。所有四家医院的平均噪声水平均超过国际建议的a加权等效连续声级(LAeq) 45 a加权分贝(dBA)和a加权最大声级(LAmax) 65 dBA。最常见的噪声源是员工谈话(30.9%,A医院)、设备报警(21.0%,B医院)和关闭金属踏板箱(20.0%,B医院)。所有医院的中高频(250 Hz - 6 300 Hz)平均LAeqs >45 BA,特别是在下午。结论。研究结果强调需要对新生儿重症监护室的医护人员进行持续的噪音监测、意识和教育。未来的研究应扩展现有的发现,并将重点放在新生儿重症监护病房的噪声控制干预措施上。

Background. Noise is a known environmental stressor in the neonatal intensive care unit (NICU), as it may result in adverse effects on preterm neonates because of the unique vulnerability and physiological immaturity of their central nervous systems. Objective. To investigate noise levels in public sector NICUs in the eThekwini District, KwaZulu-Natal Province, South Africa. Methods. An analytical observational study design with purposive sampling of public sector hospitals was used. Noise was continuously measured with a sound level meter in a central location for 48 hours on 2 consecutive days (Sunday and Monday) in the four NICUs. A sample of noise sources, as well as their frequency of occurrence, was identified through direct observation and a frequency spectrum analysis using one-third octave bands. Data were analysed using descriptive and inferential statistics. Results. This study included one tertiary hospital and three regional hospitals in the eThekwini District. Mean noise levels exceeded international recommendations of an A-weighted equivalent continuous sound level (LAeq) of 45 A-weighted decibel (dBA) and an A-weighted maximum sound level (LAmax) of 65 dBA in all four hospitals. The most frequently occurring sources of noise were staff conversations (30.9%, Hospital A), device alarms (21.0%, Hospital B) and closing metal pedal bins (20.0%, Hospital B). Mean LAeqs >45 BA were found in the mid and high frequencies (250 Hz - 6 300 Hz) in all hospitals, particularly during the afternoon. Conclusion. The findings emphasise the need for continuous noise monitoring, awareness and education among healthcare professionals in the NICU. Future research should expand on existing findings and focus on interventions for noise control in NICUs.
