Background
- A type of central line infection characterized by signs of soft tissue infection extending along the tunneled portion of the catheter
Case Definition
IDSA
- Tenderness, hyperemia, and/or induration that extends >2 cm from the exit site and along the subcutaneous tunnel
- May or may not be associated with bacteremia
CDC
- Tenderness, erythema, or site induration >2 cm from the catheter site along the subcutaneous tract of a tunneled catheter, in the absence of concomitant bloodstream infection
Management
- Send cultures of any drainage and send blood cultures
- Remove catheter, without exchange over a wire
- Insert replacement catheter at distant site
- Antibiotics
- Cover Gram-positive and Gram-negative organisms, and adjust based on culture results
- Without bacteremia, treat for 10 to 14 days
- With bacteremia, see central line-associated bloodstream infection for management
