Resumo
Healthcare Related Infections (IRAS) represent a serious public health problem and are among the leading causes of morbidity and mortality in the world. Among the types of HAI are Surgical Site Infections (SSIs) that may be due, for example, to the use of contaminated health products. In orthopedic surgeries, the occurrence of SSI is a serious complication for patients and may be associated with the use of contaminated implantable orthopedic plates. As these are critical health products that come into contact with tissues that do not have their own microbiota, they must be submitted to the sterilization process prior to use. However, failures in the processing steps, especially cleaning associated with biofilm formation in these devices, may prevent the implant from being properly sterilized. This study aimed to characterize the contamination profile of implantable orthopedic plaques by Staphylococcus spp., Before processing by the health service, and was carried out at a public teaching hospital in Goiânia, Goiás, from May to December 2018. Five Orthopedic surgical implant boxes called “Small Fragments”, provided by a consignment / lending system company, were selected 15 smaller implantable orthopedic plates collected using aseptic technique. They were submitted to bacteriological analysis for isolation and phenotypic identification of Staphylococcus spp., As well as evaluation of antimicrobial susceptibility profile. Among the evaluated implantable orthopedic plates, four (26.7%) were contaminated with Staphylococcus spp., And a total of four isolates were recovered. The most isolated species was Staphylococcus hycus (50.0%). Staphylococcus epidermidis (25.0%) and coagulase-negative Staphylococcus (25.0%) were also isolated. The microorganisms were sensitive to the evaluated antimicrobials, except Staphylococcus hyicus, which was resistant to cefoxitin, predicting methicillin / oxacillin resistance. These data point to the importance of properly performing the processing steps of these implants, considering the capacity of isolated microorganisms to form biofilm, especially when the implant presents non-conformities such as grooves, dirt, oxidation and other factors. The formation of biofilms in these devices may lead to the occurrence of chronic, severe and difficult to treat infections.
