The prevention of surgical-site infection (SSI) is of great importance. Airborne particulate correlates with microbial load and SSI. There are many potential sources of airborne particulates in theatre and from an experimental point of view impossible to control. We evaluated the effectiveness of a novel air decontamination-recirculation system (ADRS) in reducing airborne particles in a laboratory environment and controlled the introduction of particulate using diathermy. Airborne particles were measured with and without activation of the ADRS in PC2 laboratory to provide a baseline. Particles were generated in a controlled manner utilising electrocautery ablation of porcine skin tissue. Ablation was performed at 50W power (Cut) for 60 seconds at a constant rate with and without the ADRS operating in the PC2 laboratory. Particles were measured continuously in 30s intervals at two sites 0.5m and 3m from the site of diathermy. Adequate time was allowed for return to baseline between each repetition. Each experiment was repeated 10 times.Aim
Methods
London's Air Ambulance (LAA) was first set-up in 1989 as a direct result of a Royal College of Surgeons of England Report highlighting poor trauma care provision. Since its inception, the service's mission is to be an innovative and effective provider of advanced pre-hospital care. The service provides a senior Doctor and senior Paramedic to the scene of any incident within the M25 by helicopter, during the day, and by fast-response car at night. The vast majority of doctors are usually Emergency Medicine Physicians or Anaesthetists. During a 6-month tenure, doctors will usually have completed a number of procedures, which include rapid sequence induction of anaesthesia, pre-hospital blood transfusion, and, procedural sedation. In terms of innovations, the organisation was the first in the UK to provide a 24/7 service. It was also the first to start pre-hospital Rapid Sequence Induction of Anaesthesia for the severely injured; Resuscitative Thoracotomy for the victims of penetrating trauma; and pre-hospital Blood Transfusion for shocked polytrauma patients. The service also has a very thorough induction programme, for new Doctors and Paramedics, and a highly structured Clinical Governance process. The post offers a unique and privileged opportunity to treat the most severely injured at the roadside.
