“…Small differences are observed between the airflow patterns downstream of IT-1 and IT-2. In contrast to the results reported by Thore and Burman (2006), OR ventilation here affects the laminar airflow delivered by the MLAF, along the ITs.…”

“…approach) for these types of surgeries (Friberg, Friberg, & Burman, 1999). Thore and Burman (2006) examined the MLAF screen with two different ventilation systems with 6 and 16 ACH. They found that the impact area of the MLAF unit is not affected by the type of OR ventilation.…”

“…It was proven experimentally that MLAF constitutes a valuable complement to the OR ventilation in reducing the OR bacterial load (Friberg, Lindgren, Karlsson, Bergström, & Friberg, 2002;Friberg, Ardnor, Lundholm, & Friberg, 2003;Nilsson, Lundholm, & Friberg, 2010;Pasquarella et al, 2007;Thore & Burman, 2006;Whyte, Hambraeus, Laurell, & Hoborn, 1992). Friberg et al (2002) examined the MLAF as an addition to conventional turbulent mixing OR ventilation during a sham operation and they concluded that the additional MLAF screen reduced the number of viable airborne bacteria and sedimenting bacteria-carrying particles (BCPs) to the same level as for ultra-clean LAF OR ventilation units.…”

“…In another study, Friberg et al (2003) investigated MLAF screen units used in 60 standardized operations for groin hernia and they found no correlation between surface and air contamination of BCPs when MLAF was used. Thore and Burman (2006) experimentally used MLAF over instrument and operation table areas, and concluded that MLAF reduced the counts of BCPs by about 14-fold. In another similar study by Pasquarella et al (2007), the efficiency of the MLAF in reducing the bacterial contamination was evaluated in the surgical zone of an OR supplied with turbulent mixing ventilation.…”

“…1,2,7 The scientific community generally accepts that laminar flow of ultraclean air and the use of HEPA filters over a relatively large area creates a field of air intended to isolate the surgical area and team and that these factors help prevent the development of SSIs. 25,26 All of the interventions carried out in our study met these basic conditions to prevent SSIs. Some investigators, such as Brandt and colleagues, 27 propose turbulent flow; however, their study was retrospective, based on routine surveillance data in 63 departments in Germany and limited in terms of the procedures included.…”

Background: Addressing surgical site infection (SSI) is accomplished, in part, through studies that attempt to clarify the nature of many essential factors in the control of SSI. We sought to examine the link between multiple risk factors, including environmental factors, and SSI for prevention management. Methods:We conducted a longitudinal prospective study to identify SSIs in all patients who underwent interventions in 2014 in 8 selected hospitals on the Mediterranean coast of Spain. Risk factors related to the operating theatre included level of fungi and bacterial contamination, temperature and humidity, air renewal and differential air pressure. Patient-related variables included age, sex, comorbidity, nutrition level and transfusion. Other factors were antibiotic prophylaxis, electric versus manual shaving, American Society of Anaesthesiologists physical status classification, type of intervention, duration of the intervention and preoperative stay.Results: Superficial SSI was most often associated with environmental factors, such as environmental contamination by fungi (from 2 colony-forming units) and bacteria as well as surface contamination. When there was no contamination in the operating room, no SSI was detected. Factors that determined deep and organ/space SSI were more often associated with patient characteristics (age, sex, transfusion, nasogastric feeding and nutrition, as measured by the level of albumin in the blood), type of intervention and preoperative stay. Antibiotic prophylaxis and shaving with electric razor were protective factors for both types of infection, whereas the duration of the intervention and the classification of the intervention as "dirty" were shared risk factors. Conclusion:Our results suggest the importance of environmental and surface contamination control to prevent SSI.Contexte : La lutte contre les infections du site opératoire (ISO) passe entre autres par des études visant à clarifier la nature de nombreux facteurs essentiels de contrôle. Nous avons donc cherché à examiner le lien entre divers facteurs de risque, notamment de nature environnementale, et les ISO, dans une optique de prévention.
