Role of microbiological examination in diagnosis and treatment of periprosthetic infection
Objective. Determination of optimal tactics of microbiological investigation in patient, suffering periprosthetic infection (PPI), using estimation of trustworthiness of the bacteriological investigations results in preoperative and postoperative periods.
Маterials and methods. On the base of Orthopedic–Traumatological Centre of Kiev's Regional Clinical Hospital through 2016 – 2018 yrs 32 patients were examined with suspicion on presence of PPI. Two Groups of patients were formatted, in whom during preoperative preparation bacteriological investigation was accomplished: Group I – 23 patients, in whom bacteriological investigation of cultures from fistula was done; Group II – 9 patients, in whom the material for culture was taken by puncture, because the fistula aperture in them was absent.
Results. Of 147 preoperative cultures in 83 (56.5%) Gram–positive cocci were revealed, and in 49 (33.3%) – Gram–negative bacteria; while in 15 (10.2%) cultures the development of microflora was not proved. In 22 (68.7%) cases a monoculture was separated, while in 10 (31.3%) – two and more microorganisms.
Conclusion. Diagnosis of PPI constitutes a complex task and demands application of multidisciplinary approach, which supposes close cooperation of physicians–orthopedics and microbiologists.
