Seventy-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. ⋯ 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.

A survey of operating theatres in Great Britain and Ireland by postal questionnaire was undertaken to determine the number of non-ventilated theatres in use, the number of designated theatres for specialist surgery and how and when bacterial sampling is conducted. Replies were received from 147 centres covering 438 operating theatre suites. Eighty-seven (59%) centres contained three or fewer suites and only 32% did not have a designated theatre for any specialist surgery. ⋯ Four percent of plenum and 9% of ultraclean theatres are never monitored bacteriologically and settle plates are used in 72 (49%) centres. This survey suggests there is some confusion over the indications for bacteriological monitoring and what constitutes acceptable standards. The use of non-ventilated theatres, except for the most minor of procedures, is of some concern and should be phased out.
