作者对１０个病室换床单前、中、后空气细菌、飘尘量进行了监测。结果表明：换床单过程中空气细菌、飘尘量明显升高（Ｐ＜０．０１），分别超过标准４．８５倍和１４．４７倍。换床单后１小时，空气中细菌、飘尘量基本恢复到操作前水平。细菌与飘尘呈正相关。细菌、飘尘与相对湿度呈负相关。文章分析了换床单引起空气细菌、飘尘污染的原因及危害。认为在重视防止病室空气细菌污染的同时，还应重视防止病室空气飘尘污染。可通过人工加湿、合理安排换床单时间、加强棉絮处理、限制操作人数、强化正规操作、避免病床拥挤等方法，控制换床单时细菌、飘尘再次飞扬，减轻病室空气污染。
The author of 10 wards for bed sheets before, during, after the air bacteria, the amount of dust carried out monitoring. The results showed that the amount of airborne bacteria and airborne dust was significantly increased (P <0.01), which exceeded the standard 4.85 times and 14.47 times, respectively. 1 hour after the change sheet, the bacteria in the air, the amount of dust returned to the pre-operation level. Bacteria and fly dust were positively correlated. Bacteria, flying dust and relative humidity was negatively correlated. The paper analyzes the causes and hazards of airborne bacteria and flying dust pollution caused by changing sheets. In the meantime, we should attach great importance to prevent the airborne dust in the ward from being polluted. By artificial humidification, reasonable arrangements for bed linen time, strengthen the cotton processing, limit the number of operations, strengthen the formal operation, to avoid beds and other methods to control the change sheets bacteria, flying dust again to reduce ward air pollution.
