چکیده
زمینه و هدف: بیوآئروسل‌های موجود در هوای بیمارستان منابع بالقوه عفونت برای بیماران وکارکنان محسوب می‌شوند. این مطالعه با هدف بررسی نوع و تراکم بیوآئروسل‌های باکتریایی بیمارستان منتصریه مشهد در سال 1400 انجام شد.
مواد و روش ها: در این مطالعه مقطعی -تحلیلی 96 نمونه از هوای بخش‌ها و اتاق‌های عمل بوسیله پمپ نمونه‌بردار با دبی L/min 28/3 و ایمپکتور تک مرحله‌ای اندرسون به مدت 5 دقیقه با دستورالعمل NIOSH0800 برداشت شد و بعد از کشت تعداد کلنی بر حسب cfu/m3 محاسبه شد. جهت تجزیه و تحلیل داده‌ها از نرم افزار SPSS استفاده شد.
یافته‌ها: نتایج نشان داد که بیوآئروسل‌های باکتریایی شایع در هوای این بیمارستان شامل میکروکوکوس لوتوس، کوکوریاکریستین و استافیلوکوکوس هومینیس بود و میانگین تراکم بیوآئروسل‌ها، cfu/m3 57/81 (اتحراف معیار= 42/44) بود که با رهنمود پیشنهادی سازمان بهداشت جهانی مطابقت داشت. در این مطالعه بیشترین میانگین تراکم مربوط به بخش مراقبت‌های ویژه با میانگین cfu/m3 101/08 (انحراف معیار=48/93) و کمترین میانگین تراکم مربوط به بخش پیوند مغز استخوان با میانگین cfu/m3 5/25 (انحراف معیار= 7/96) بود.
نتیجه‌گیری: با توجه به نتایج بدست آمده در این مطالعه، تراکم بیوآئروسل‌ها در بخش‌های مختلف، متفاوت بود ولی از نظر نوع مشابهت وجود داشت. تفاوت میزان تراکم بیوآئروسل‌های باکتریایی احتمالا به عواملی مانند تعداد بیماران بستری و پرسنل مرتبط با هر اتاق، کیفیت تهویه، و وضعیت گندزدایی محیط ارتباط دارد.

چکیده [English]
Background and Purpose: Hospital air contains bioaerosols that are potential infection sources for patients and staff. This study focused on identifying and quantifying bacterial bioaerosols in Montaserieh Hospital, Mashhad, in 2021.
Materials and Methods: This cross-sectional analytical study collected 96 air samples from operating rooms and wards using a sampling pump with a flow rate of 28.3 L/min and a single-stage Anderson impactor by NIOSH0800 guidelines. The samples were cultured, and bacterial colonies were quantified as colony-forming units per cubic meter (cfu/m³). Data analysis was performed using SPSS software.
Results: Predominant bacterial bioaerosols identified included Micrococcus lotus, Coccoriacristina, and Staphylococcus hominis. The mean density of bioaerosols was 57.81 cfu/m³ (standard deviation = 42.44), aligning with World Health Organization guidelines. The intensive care unit exhibited the highest average density at 101.08 cfu/m³ (standard deviation = 48.93), whereas the bone marrow transplant ward had the lowest at 5.25 cfu/m³ (standard deviation = 7.96).
Conclusion: The study revealed varying densities of bacterial bioaerosols across different hospital wards, though the types of bacteria were consistent. Variations in bioaerosol density likely relate to the number of patients and staff per room, the quality of ventilation, and environmental sanitation standards.
