Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Joint aspirations are performed by orthopaedic surgeons with an 18-gauge needle according to standardized aseptic technique. Intraoperative punctures are performed prior to arthrotomy. A minimum of 1ml of joint aspirate is immediately transferred to a native study vial for our study, a native vial for gram stain and culture and a native vial for polarization microscopy, respectively. A minimum of 1 ml joint aspirate is transferred to an ethylenediaminetetraacetic acid (EDTA) vial for the determination of leucocyte count. Finally, a minimum of 1 ml is inoculated into a paediatric blood culture bottle.
Standard microbiological methods are performed in an external laboratory that routinely collaborates with our clinic. Leucocyte count is performed automatically with the mentioned EDTA vial. Polarization microscopy is performed at our pathohistological department in order to detect crystals and signs of infection in joint aspirate.
If written informational consent has been signed by the patient, the study vial is immediately transported to our internal laboratory for analysis with new diagnostic methods (microcalorimetry, PCR, etc.). When an immediate transportation was not feasible, the vial is stored in a cooling fridge at +3° C until transportation was possible.
Each case is individually reviewed and classified by an experienced infectiologist taking the case's clinical history and laboratory results into account.
