Surgical site infection (SSI) is the most significant postoperative complication. The sources of microorganisms that cause SSIs in healthcare facilities are multifactorial in origin and they may be endogenous (e.g. patient’s own normal skin flora) or exogenous (e.g. airborne bacteria-carrying particles [ABCPs]). The skin flora of patients is the direct source of contamination in only 2% of cases and remaining 98% of cases connected to ABCPs. Therefore, the current study tried to provide useful information for surgical team about the roleof ABCPs in contamination of sterile surfaces in the operating room (OR); moreover, this study provided strategies to deal with it.

The present research was a descriptive study performed by review method. Data were collected by searching various databases including Science Direct, PubMed, Scopus, and Google scholar search engine.

Surgical wound contamination (SWC) and SSI prevention depends on minimization of ABCPs. Hence, maintaining clear air in the OR by using the efficient ventilation systems, limiting traffic and opening doors and using of non-woven fabric instead of cotton fabric can maintain low ABCPs in the OR environment and they reduce the chances of infections by ABCPs transmission.

Everyone on the surgical team is responsible for establishing and maintaining a sterile field by using sterile techniques to prevent SWC and SSI. The results of this review suggests that OR staff should be educated about routes of sterile field contamination by ABCPs to be able to prevent risk of SWC and incidence of SSI.

Bioaerosols are airborne particles which can cause a wide range of health effects including hospital and occupational infections, acute toxic effects, allergies and cancer. Hence, the aim of this study was the qualitative and quantitative evaluation of bioaerosol in different wards of Malayer city’s hospitals. Sampling was conducted from twelve wards in two hospitals. Both bacterial and fungal sample were taken based on method of ACGIH bioaerosol committee. The samples were transported to blood agar and sabouraud medium then cultivated immediately. The type and number of colonies were determined in the laboratory then, the bioaerosol concentration was calculated in terms of cfu/m3. Overall, the maximum concentration of bacterial (21.27 cfu/m3) and fungal (66.49 cfu/m3) colonies were found in pediatric and CCU wards, respectively. The minimum concentration of both bacterial (8.74 cfu/m3) and fungal (2.18 cfu/m3) colonies were found in autoclaving ward. Staphylococ negative coagulase(33.76%), Micrococ species(16.23%) and Bacillus species(15.58%) were found to be the most common organisms and, Penicillium spp. (50.9%), Cladosporium spp. (27.02%) and Aspergillus spp. (8.1%) were the most common fungal genus. Except of a few cases, total concentration of bioaerosols was lower than the guideline concentration (30 cfu/m3) in the all wards. High concentrations of bioaerosols in some wards can be explained by some reasons such as wear and tear of buildings, improper ventilation, incomplete disinfection of wards and, the high number of patients and visitors.
