AbstractSeventy-eight patients with culture-positive epidural catheters, were studied. Fifty-nine had symptoms of exit site infection and 11 patients had clinical meningitis, two of whom also had an epidural abscess. This corresponds to a local infection incidence of at least 4.3% and an incidence of central nervous system infection of at least 0.7% at Odense University Hospital. This degree of infection is of the same magnitude as that reported for intravascular devices. We found that the patients with generalized symptoms of infection had been catheterized for a longer time, and were older than patients with only local symptoms of infection. The microorganisms isolated from the tips of the epidural catheters were coagulase-negative staphylococci (41%), Staphylococcus aureus (35%), Gram-negative bacilli (14%) and others (10%). The Gram-negative bacilli and S. aureus caused serious infections more frequently than the others. We discuss the symptoms and diagnosis of spinal epidural abscess and suggest a proposal for prophylactic and diagnostic guidelines for epidural catheter-related infections.
