Re-examining causes of surgical site infections following elective surgery in the era of asepsis. government site. However, new multi-centre trials to assess this or the use of national prospective surveillance systems to explore other variables that might explain these findings such as poor operating room discipline are needed, to resolve this important surgical issue. The incidence of a vortex-free laminar flow on a surface with particles prevents these from. In joint replacement surgeries, one of the main causes of early (within 3 months) and delayed (within 18 months to 2 years) deep prosthetic infections was found colonisation during surgery (Knobben 2006). Laminar air flow is supposed to minimize contamination by mobilizing uniform and large volume of clean air to the surgical area and Contaminants are flushed out instantly (Chow and Yang, 2004). It may be difficult to identify such organisms through standard culture techniques (Tunney 1998). The available evidence shows no benefit for laminar airflow compared with conventional turbulent ventilation of the operating room in reducing the risk of SSIs in total hip and knee arthroplasties, and abdominal surgery.
