Studies conducted to evaluate the effectiveness of laminar flow produced mixed results and there is no consensus on its role in infection control (Sandiford 2007). Surgical area contamination--comparable bacterial counts using disposable head and mask and helmet aspirator system, but dramatic increase upon omission of head-gear: an experimental study in horizontal laminar air-flow. Mobile laminar air flow screen for additional operating room ventilation: reduction of intraoperative bacterial contamination during total knee arthroplasty. and transmitted securely. Infection control is a fundamental aspect of a nurses role. Theatres are usually designed with a vertical downward airflow concept. Study by Knobben et.al (2006) found that combination of systemic and behavioural changes are required to prevent intra-operative contamination. Their study compared the reoperation rate between theatres with laminar air-flow and theatres without laminar air-flow system. Laminar-flow operating theater that comprises a support (4) that defines a horizontal plane, on which the patient (2) rests, which has a main longitudinal direction, on which support (4) there is, in addition, an operating region (R), laminar-flow-emitting unit (5) and an air-absorption unit (6), wherein the laminar-flow-emitting unit (5) emits .

Supporting this finding Scaltriti et.al (2007) found well designed ventilation system is effective in reducing contamination. Effect of laminar airflow ventilation on surgical site infections: a systematic review and meta-analysis. However, apart from the initial Medical Research Council study, there are few clinical studies demonstrating a convincing correlation between decreased SSI rates and LAF. We call the laminar flow a streamline or viscous flow. 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).

Nurses and managers should emphasise on controlling factors like the traffic in theatre, limiting the number of staff and reinforcement of strict aseptic technique (Allen 2010). Non-adherence to the principle of asepsis by surgical team is identified as a significant risk factor of infections. Horizontal Laminar Air Flow . Except in Group 1 (p=0.022) late phase contamination was not significantly higher than early phase contamination. They found that re-operation rate in no-laminar air-flow theatres were four times greater than that in laminar airflow theatres. This means that the operating area is completely isolated within the surrounding room, effectively preventing any contamination by bacteria or virus-laden air. 0.38m/S Flow Hood Fan Filter Unit SUS201 High Efficiency Laminar Flow Hood .

This systematic review and meta-analysis included 12 observational studies comparing laminar airflow with conventional ventilation in the operating theatre. For example researches were making statements such as the introduction of water-impervious drapes and gowns did not seem to make a statistically significant improvement in the result. (p.823). There are studies which found that laminar air-flow system is not effective in reducing infection rate. Several studies have demonstrated decreased air bacterial contamination with LAF using bacterial sedimentation plates placed in key areas of the operating room. 2003 Oct;55(2):92-7. doi: 10.1016/s0195-6701(03)00143-9. Departments using artificial operating room (OR) ventilation with either turbulent or laminar airflow was included in this study. Our mobile and modular operating theatre facilities can offer a significant increase in capacity during downtime for operating theatre refurbishment or during periods of high patient demand.

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). Clarke et.al (2004) found that contamination was not significantly different in ultra clean theatres compared to standard theatres equipped enhanced ventilation system. Their study compared the wound contamination during primary total hip replacement (THR) performed in standard and ultra clean operation theatres. laminar-flow operating theatre that comprises a support (4) that defines a horizontal plane, on which the patient (2) rests, which has a main longitudinal direction, on which support (4). The efficacy of operating room ventilation is measured by the colony forming units (CFU) of organisms present per cubic meter. We have prospectively studied 50 patients who underwent elective and orthopaedic trauma procedures during which a suction system was used. However, more recent evidence has questioned its clinical importance. Free resources to assist you with your nursing studies!

Laminar flow ventilation systems were pioneered by Sir John Charnley , when used in conjunction with other strategies to reduce sepsis, reported marked decline in post-operative wound infection. Of those 435 patients, 212 had operation in laminar air-flow theatres and 223 had operation in non-laminar air-flow theatres.
