The Rhys-Davies exsanguinator: a potential source of bacteria in orthopaedic operations

Infection complicating hip and knee joint arthroplasty continues to provide significant morbidity to patients. Sources of infectious pathogens in the operating theatre include theatre personnel and equipment in close contact with the patient. The role of the venous exsanguinator as a potential source of skin contamination was studied over 5 consecutive days in a single centre performing knee arthroplasty and arthroscopy. All samples were positive for common skin organisms. The potential for transfer and contamination of patients with significant pathogens may be present when utilising a venous exsanguinator. The use of a specific cleaning procedure for venous exsanguinators should be applied between each operative case, thereby reducing the transmission of potentially significant pathogens.
