摘　　要：目的分析医院急诊抢救室的噪声暴露现状,为控制医院噪声、优化护理工作环境提供依据。方法应用噪声统计分析仪测量急诊抢救室各种噪声,并连续24 h监测环境噪声,分析每小时等效声级、最大声级、最小声级、平均峰值、平均中值、平均本底值。同时记录测量期间护士工作状况及引起噪声突然改变的事件。结果急诊抢救室24 h昼间和夜间的等效声级分别为(69.96±3.51)dB(A)和(64.84±2.66)dB(A),夜间的最大声级为(91.06±4.44)dB(A)。昼间的等效声级、最小声级、平均峰值、平均中值、平均本底值均高于夜间,差异均有统计学意义(P<0.01);昼间的最大声级略高于夜间,差异无统计学意义(P>0.05)。结论急诊抢救室的噪声水平远高于规定限值,主要来源于医疗设施和谈话声。应加强医护人员行为干预、医疗设备管理和环境优化,降低医院环境噪声。Objective To analyze noise exposure in emergency room and to provide basis for the control of hospital noise so as to optimize nursing working environment.Methods Noise statistics analyzer was used to measure various kinds of noise in emergency room and continuous monitoring of noises in emergency room over 24 h was performed and analysis was conducted about A-weighted sound pressure level（Leq）,maximum sound level（Lmax）,minimum sound level（Lmin）,average peak,average value,and average background value of each hour.Working conditions of nurses and events causing a sudden change of noise were also recorded.Results The Leq per hour during day-time and night-time were（69.96±3.51）dB（A） and（64.84±2.66）dB（A） respectively.The Lmax of night-time was（91.06±4.44）dB（A）.The hourly Leq,Lmin,average peak,average value,and average background value of day-time were higher than those of night-time.The difference was statistically significant（P0.01）,while difference of hourly Lmax among day-time and night-time was not（P0.05）.Conclusion Noise level of emergency room is much higher than standard level of WHO and China.Noise mainly comes from medical facilities and conversation.Behavioral intervention of health care workers,medical equipment management and environmental optimization should be strengthened to reduce hospital noise.
