Bacterial colonization of epidural catheters used for short-term postoperative analgesia: microbiological examination and risk factor analysis.

摘要: Background: The authors conducted this prospective study to determine the incidence, potential routes, and risk factors of microbial colonization epidural catheter used for postoperative pain control. Methods: Two-hundred five patients with analgesia were studied. On removal catheter, samples sent culture: infusate, a swab from inside hub connector, skin around insertion site, subcutaneous segment, tip catheter. Clinical data related insertion, management, general patient conditions collected. Results: positive culture rates segments 10.5% 12.2%, respectively. most common organism in was coagulase-negative staphylococcus. There strong linear relationship between bacterial site growth (P 0.000). Catheter-related events at ward, blood transfusion, catheters. Inflammation indwelling time, level not predicators colonization. Conclusions: authors’ results suggest that migration along track is route Maintaining sterile will reduce tip. EPIDURAL an effective method management. However, infection may occur after procedure. Although reported catheter-related are low, 1–3 some these infections, such as abscess, serious life-threatening without early diagnosis treatment. 3–5
