Abstract:
OBJECTIVE To investigate the incidence of bacteria colonization on lumbar epidural catheter tips in postoperative analgesia patients. METHODS The catheter tips were cultured in 100 patients with ASA grade Ⅰ-Ⅱ undergoing lower extremity osteoarticular operation.Lumbar epidural catheters were placed in the operating room with aseptic technique.Diluted local anesthetic and fentanyl infusions were used for postoperative analgesia.The epidural catheter was removed with aseptic technique and the tips sent for microbiological culture after 3 days. RESULTS From 100 patients,bacteriological examination revealed bacteria colonization in 9(9.0%),mainly Staphylococcus epidermidis(6;66.7%),followed by Enterococcus(1;11.1%),Gram-negative bacilli(1;11.1%),and yeasts(1;11.1%).No patient developd infectious complications. CONCLUSIONS Our results show that the risk of bacteria colonization associated with lumber postoperative analgesia in three days is low.No patient develops local or central nervous infection.Epidural postoperative analgesia can be routinely used without worry of infection in epidural space.But we recommend prophylactic measures should be applied in the high-risk groups.
