Noise in the postanesthesia care unit (PACU) is a significant source of postoperative patient discomfort and can affect patient sleep and recovery. Interventions involving structural alterations in the environment reduce noise and improve patient satisfaction; however, there are no studies focusing on staff education as a method to reduce PACU noise.
We designed and implemented a prospective PACU noise reduction program using education and training to minimize staff contributions to noise.
Noise levels, measured hourly with a decibel meter, patient satisfaction, and patient rest were assessed before and after implementation.
We found statistically significant decreases in noise levels and increases in patient satisfaction scores after the implementation of our noise reduction project.
These findings demonstrate that an inexpensive and easily implemented noise reduction program can effectively reduce environmental noise, increase patient satisfaction, and potentially improve recovery.
麻醉后护理病房（PACU）中的噪音是术后患者不适的一个重要来源，会影响患者的睡眠和康复。涉及环境结构改变的干预措施可以降低噪音并提高患者满意度；然而，目前尚无研究关注员工教育作为降低 PACU 噪音的方法。
我们设计并实施了一项使用教育和培训来最大限度减少员工噪音贡献的前瞻性 PACU 降噪计划。
在实施前后，使用分贝计每小时测量噪音水平、患者满意度和患者休息情况。
我们发现，实施降噪项目后，噪音水平有了统计学意义上的降低，患者满意度得分也有所提高。
这些发现表明，一个廉价且易于实施的降噪计划可以有效地降低环境噪音，提高患者满意度，并可能促进康复。
