Management of fever in patients with central vein catheters

We have evaluated a standardized prospective system for managing episodes of fever in pediatric patients with indwelling central vein catheters being used primarily for delivery of parenteral nutrients. Over an 18-month period 72 such patients, accounting for 4347 "catheter days," were followed. Thirty-two patients experienced a total of 88 episodes of fever. An infection unrelated to the presence of the catheter (e.g. otitis media, pneumonia, urinary tract infection) was found to be the cause of fever in 27 episodes (31.7%); in all the infection responded to appropriate antibiotic therapy. Ten of the episodes of fever (11.4%) lasted for less than 2 hours and were not evaluated further. Two episodes occurred in patients who no longer required the catheter; these resolved with elective catheter removal. The cause of the remaining 49 episodes of fever was assumed to be catheter-related sepsis; these were treated empirically with an intravenous antibiotic regimen of vancomycin (40 mg/kg/day) and gentamicin (7.5 mg/kg/day). In 16 of these cases blood cultures were negative and the antibiotic regimen was either stopped or continued for other indications. The remaining 33 episodes of fever were associated with positive blood cultures, i.e. documented episodes of catheter-related sepsis. In 10 of these the catheters were removed. The remaining 23 episodes of catheter-related sepsis were treated for 14 days with antibiotics given through the central vein catheter. In 5 of these episodes blood cultures remained positive after 48 hours of specific antibiotic therapy at which time the catheter was removed.(ABSTRACT TRUNCATED AT 250 WORDS)
