laminar flow in operation theatre
The practice became widely adopted in orthopaedic theatres after a series of trials that showed a significant decrease in infections from laminar flow theatres 2.. Our study aims at comparing the post operative infection rate following orthopaedic surgey between laminar operation theatre and conventional operation theatre Methodology This is a prospective study conducted in department of orthopaedics, government general hospital, Guntur between September 2018 and September 2019 for a period of 1 year. Their study compared the reoperation rate between theatres with laminar air-flow and theatres without laminar air-flow system. 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. Among the control group contamination was found 32.9% while in intervention group 1 it was 34.3% and in intervention group 2 it was 8.6%. The report highlights the cause of bacterial meningitis and generally covers the pathogenesis, diagnosis, and treatment of the disease. Critical Review of Infection Control Precautions for Patients after Elective Surgery.

How safe is the suction tip? that suggested a benefit of ultra clean ventilation (of which laminar airflow ventilation is an example) was published in 1987, before the introduction of active warming to prevent inadvertent perioperative hypothermia. 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). Many ventilation systems do much better than that, by employing High Efficiency Particulate Air filtration commonly known as HEPA, which by definition removes >99.97% of germ sized particles from the airflow. Key Words: distal radius, intra articaular fracture, volar plating, external fixator, DASH scoring system. Retrospective data was obtained over a 5 year period from January, 2007 to December, 2012.

Mobile laminar air flow screen for additional operating room ventilation: reduction of intraoperative bacterial contamination during total knee arthroplasty. Based on the experience , Microflow is contributing to the improvement of Hospital areas and reducing the risk of infection by designing and Commissioning the Laminar Airflow systems. This systematic review and meta-analysis included 12 observational studies comparing laminar airflow with conventional ventilation in the operating theatre. Dust particles act as a carrier for transporting microorganisms laden particles and can settle on surgical wound and there by cause infection (Neil 2005). For their study Miner et.al (2007) selected 411 hospitals which have submitted the claim for total knee surgery (TKR) for the year 2000 from four US States were surveyed to collect the details of use of laminar air flow system and body exhaust suits. Implementing a Trauma and Acute Care Surgery Service in a Regional Hospital. Prevention of infection in primary THA and TKA. Non-adherence to the principle of asepsis by surgical team is identified as a significant risk factor of infections. Those hospitals which were fulfilled three criteria were included in this study. The OP Room Theatre air feeding rate 2005 figure, must be for OP Rooms Operation table, instruments and opreation In the Laminar Air Flow (LAF) system, the entire body of air within a designated space moves with uniform velocity in a single direction along parallel flow lines, and is restricted to an area in the centre of the operating theatre (room within a room principle). Departments using artificial operating room (OR) ventilation with either turbulent or laminar airflow was included in this study. Laminar air-flow system is expensive and require continues maintenance. Epub 2020 Jan 29. Study by Knobben et.al (2006) found that combination of systemic and behavioural changes are required to prevent intra-operative contamination. Researchers suggest that human movement rather than human presence is the factor that determines airborne microbial contamination. Miner et.al (2007) found that there were no significant differences in infection between hospitals that use laminar airflow and body exhaust suits. Conclusion Laminar flow operation theatre has no added advantage in the prevention of post operative surgical site infection compared to conventional operation theatre, Abstract: Pertrochanteric fracture is a severe and frequent injury with consequent high morbidity and mortality. Intense behavioural and systemic changes were introduced to second intervention group of 70 operations.

Thats why there is one interlock guard system controlled the inlet and the outlet of PASS BOX not be opened at the same time, in order to prevent the cross contamination. Discussion: Early studies reported lower infection rates with laminar air flow and therefore it became the accepted standard for implant-related surgery. The ergonomic units deliver an ultraclean, horizontal flow of air directly over the surgical instruments or minor wound site, minimising the presence of bacteria-carrying particles. We call the laminar flow a streamline or viscous flow. The studies of the Charit-group and some other studies included in the meta-analysis. 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). Other than mentioning few studies researchers failed to provide any background of the research problem. (I will add critique of this study here).

Keywords used for this search are laminar air flow, surgical site infection, operating room air quality, airborne infections + operating theatre, LMA + infection control. Indoor air in an operating theatre contains dust which consists of substances released from disinfectant and sterilizers, respiratory droplets, insect parts smoke released from cautry. Laminar air-flow system is mainly used in implant surgeries where even a small number of microorganisms can cause infection. Effect of laminar airflow ventilation on surgical site infections: a systematic review and meta-analysis. It is based on tension band principle which allows compression of fracture fragment when the patient bears weight with consequent high rates of union and restoration of hip function to pre injury level. View Mobile Number. The Laminar airflow system with HEPA Filter creates an extremely homogeneous laminar flow with very little turbulence. When an individual has an infection, micro-organisms enter the body through a susceptible host, meaning that the infection will manifest within the body. 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). Suction during orthopaedic surgery. Statistical analysis found that contamination rate at the end of the surgery is not statistically different than the start (p=0.1). Decision makers, medical and administrative, should not regard laminar airflow as a preventive measure to reduce the risk of SSIs. Please enable it to take advantage of the complete set of features!

The Laminar airflow system with HEPA Filter creates an extremely homogeneous laminar flow with very little turbulence. Conventional Ventilation. Consequently, this equipment should not be installed in new operating rooms. Even though the sample size was large, limited number of events (28) were there to be observed. Surgical departments were grouped into categories according to the type of ventilation system installed. The CG- system creates an extremely homogeneous laminar flow with very little turbulence. To improve patient outcome, it is necessary for the nurses to take lead role in environmental control and identifying hazards through environmental surveillance (Neil 2005). (Sandiford and skinner 2009). The over-all 90-day incidence of deep infection, subsequent operation was found required only in 28 cases (that is 0.34%). Ann Ig. The infection rate in laminar operation theatre was 3.26% and in conventional operation theatre was 4.3%. Sossai D, Dagnino G, Sanguineti F, Franchin F. J Orthop Traumatol. Sample size seems sufficient. Disclaimer: This essay has been written by a student and not our expert nursing writers. This is achieved by installing excellent quality HEPA filters. Studies include in this review has used either clinical outcomes (infection or reoperation rate) or intermediate outcomes (particle count or bacterial count) to evaluate the effectiveness of laminar flow. 19 out of 20 had excellent to fair outcomes. Samples taken from the ultra-clean theatres, none was positive by culture while only 6 were positive by PCR. The low degree of turbulence also provides a pleasant working environment for medical personnel.
