  • 摘要:
    目的 了解西安市洁净手术室空气质量情况, 探讨可能的影响因素, 为提高手术室管理质量提供数据支持。
    方法 依据GB50333-2013《医院洁净手术部建筑技术规范》, 采用现场监测的方法, 于2017-2021年对西安市41所医院242间洁净手术室空气进行监测, 并对结果进行比较和分析。
    结果 共调查二级医院洁净手术室130间, 三级医院112间; Ⅰ级79间、Ⅱ级26间、Ⅲ级137间。沉降菌合格率为98.35%, Ⅰ级手术室为94.94%, 低于Ⅱ级和Ⅲ级手术室(χ2=6.565, P=0.022)。尘埃粒子合格率为69.01%, 其中Ⅰ级手术室为43.04%, 不同级别手术室差异具有统计学意义(χ2=37.304, P < 0.001);三级医院尘埃粒子合格率为61.61%, 低于二级医院(75.38%;χ2=5.340, P=0.021)。≥0.5 μm和≥5 μm粒径尘埃粒子合格率分别为85.12%和74.79%。在尘埃粒子不合格的手术室中, ≥0.5 μm和≥5 μm尘埃粒子均不达标者占29.33%, 仅≥0.5 μm尘埃粒子不达标者占18.67%。多因素logistic回归分析显示, 洁净手术室空气质量影响因素包括监测年份及手术室级别, 而采样区域、医院级别与研究结局无统计学关联。
    结论 西安市洁净手术室空气质量不容乐观, 监测合格率受监测年份和手术室洁净级别影响, 需加强洁净手术室常规管理及监测。

     

    Abstract:
    OBJECTIVE To investigate the current status of air quality in clean operating rooms in Xi′an and explore the possible influencing factors, thus to provide data support for improving the quality of operating room management.
    METHODS According to GB50333-2013 "Architectural technical code for hospital clean operating department", on-site monitoring was conducted from 2017 to 2021 on the air quality of 242 clean operating rooms in 41 hospitals in Xi′an, and the results were compared and analyzed.
    RESULTS Among the operating rooms being surveyed, 130 were from secondary hospitals, 112 from tertiary hospitals; seventy-nine were ClassⅠoperating rooms, 26 were ClassⅡ, 137 were ClassⅢ.The pass rate for settling bacterial was 98.35%, with 94.94% for ClassⅠoperating rooms, which was significantly lower than that in ClassⅡand ClassⅢ operating rooms (χ2=6.565, P=0.022).The pass rate for dust particles was 69.01%, with 43.04% for ClassⅠoperating rooms, and there was significant difference among different levels of operating rooms (χ2=37.304, P < 0.001).The pass rate for dust particles in tertiary hospitals was 61.61%, lower than that in secondary hospitals (75.38%;χ2=5.340, P=0.021).The pass rate for dust particles ≥0.5 μm and ≥5 μm were 85.12% and 74.79%, respectively.Among the operating rooms with unqualified dust particles, those with both ≥0.5 μm and ≥5 μm dust particles not meeting standards accounted for 29.33%, and those with only ≥0.5 μm dust particles not meeting standards accounted for 18.67%.Multivariate logistic regression analysis showed that influencing factors for air quality in clean operating rooms included the year of monitoring and the level of the operating room, while the sampling area and hospital level were not statistically associated with the outcomes.
    CONCLUSION The overall air quality of operating rooms in Xi′an is not optimistic, the pass rate is affected by the year of monitoring and the clean levels of the operating rooms, indicating a need to strengthen routine management and monitoring of clean operating rooms.
