摘　　要：目的对河北医科大学第二医院空气进行采样分析,了解医院空气污染真菌的种类分布,并对所处环境中的医患提供合理的防护建议。方法于2019年6月3-7日对河北医科大学第二医院呼吸科、血液科、普外科、神经外科、妇科、儿科、肿瘤科、门诊大厅、ICU、消毒供应中心室内环境的空气进行采样,采用曝皿法营养琼脂培养基进行真菌的培养和分离鉴定,对所得数据进行统计学分析。结果 10科室空气污染真菌密度(x^(-)±s,CFU/m^(3))分别为:呼吸科197.68±74.57,血液科213.18±65.08,普外科243.80±2.69,神经外科254.91±48.92,妇科316.37±59.38,儿科349.76±48.83,肿瘤科204.95±45.68,门诊大厅463.92±33.77,ICU 228.16±63.63,消毒供应中心188.88±17.85。10科室间空气真菌密度差异有统计学意义(F=9.668,P<0.01)。空气中的真菌以青霉属、枝孢属、节菱孢属、链格孢属、曲霉为主,分别占23.10%、12.05%、10.44%、10.10%和8.72%。结论医院空气中的真菌种类多样,各科室(病区)均有分布,医院环境中的医患存在感染的风险,因此应加强医院环境的消毒,减少院内感染的发生。Objective To assess the air samples collected in the the Second Hospital of Hebei Medical University,identify airborne fungal species,and provide reasonable protection suggestions for doctors and patients in the environment. Methods aeration dish method was used to collect and cultivate airborne fungi from 3 to 7 June,2019.Ten sites in Second Hospital of Hebei Medical University were selected as study sites which included respiratory department,hematology department,general surgery department,neurosurgery department,pediatric department,oncology department,outpatient hall,intensive care unit(ICU),and disinfection supply center.The incubated fungal colonies were identified,and the statistical analysis was then conducted. Results The mean of airborne fungal levels (x^(-)±s,CFU/m^(3)) of the 10 different sites,including respiratory department,hematology department,general surgery department,neurosurgery department,pediatric department,oncology department,outpatient hall,ICU,and disinfection supply center,was 197.68±74.57,213.18±65.08,243.80±2.69,254.91±48.92,316.37±59.38,349.76±48.83,204.95±45.68,463.92±33.77,228.16±63.63,and 188.88±17.85,respectively,among which and the differences were statistically significant(F=9.668,P<0.001).The predominant fungi in this study were Penicillium(23.10%),Cladosporium(12.05%),Arthrinium(10.44%),Alternaria(10.10%),and Aspergillus(8.72%). Conclusion The hospital air was generally contaminated by high levels of airborne fungi.Therefore,the implementation of proactive policies and strategies are needed to monitor hospital air quality in sensitive zones as well as other areas of the hospitals.
