Zoned vertical ultraclean operating room ventilation: A novel concept making long side walls unnecessary

Surgical-site infections within 60 days of coronary artery by-pass graft surgery

“…The surgical procedures were performed in a operating room with ultra clean air with , 10 cfu/m 3 . 22 The staff wore tightly woven scrub suits, which prevented bacteria from the skin flora being released into the air. 23 All patients had intravenous glucose infusions during the operation and during the first 24 h postoperatively.…”

“…19 A preoperative risk factor is the duration of preoperative stay in hospital. 2 Intra-operative risk factors are the use of the internal mammary artery (IMA), 20 duration of operation, duration of cardiopulmonary by-pass (CPB), duration of aortic cross clamping, 21 hygiene in the operating room, 22,23 and presence of glove punctures. 24 Postoperative risk factors are reoperation due to causes other than infection 2,20 and erythrocyte concentrate transfusions.…”

Further bacteriological evaluation of the TOUL mobile system delivering ultra-clean air over surgical patients and instruments

“…This approach minimizes the entrapment of surrounding air into the high efficiency particulate air filters (HEPA)-filtered air flow, making side walls unnecessary in downflow EUAs, and thus increases their versatility. 1 Although clinical efficacy of ultra-clean OR air systems has been claimed in orthopaedic implant surgery, 2,3 their cost and inflexibility currently prohibits their general use in such procedures and other high-risk surgery including thoracic and arterial procedures, neurosurgery and radical neck dissections.…”

Peri-operative glucose control and development of surgical wound infections in patients undergoing coronary artery bypass graft

“…The surgical procedures were performed in an operating room with ultraclean air [!10 colony-forming units (CFU)/m 3 ]. 14 The staff wore tightly woven scrub suits that prevented bacteria from the skin flora being released into the air. 15 The day of operation was denoted as day 0, and day 1 started at 6 a.m. the morning after surgery.…”
