Central line-associated bloodstream infections (CLABSI) kill approximately 28,000 ICU patients annually and cost over $46,000 per episode. Most CLABSIs are preventable with consistent adherence to the central line bundle.

Central Line Types

TypeInsertion SiteTip LocationLumensCommon Uses
CVC (Central Venous Catheter)Internal jugular, subclavian, femoral veinSuperior vena cava (SVC); inferior vena cava (IVC) for femoral1–5CVP monitoring, vasopressors, TPN, multiple infusions
PICC (Peripherally Inserted Central Catheter)Basilic or cephalic vein in upper armSVC/cavoatrial junction1–3Antibiotics, chemotherapy, TPN; longer duration (up to 1 year)
Tunneled CVC (Hickman, Broviac)Internal jugular or subclavian, tunneled under skin to chest exit siteSVC1–3Long-term home infusion, chemotherapy, dialysis
Implanted Port (Port-a-Cath)Subcutaneous reservoir with catheter to SVCSVC1–2Intermittent chemotherapy, blood draws; accessed with Huber needle
Hemodialysis Catheter (Permcath)Internal jugular or femoralRight atrium / SVC2 (arterial + venous)Hemodialysis only — do NOT use for other infusions without specific orders
PA Catheter (Swan-Ganz)Internal jugular or subclavianPulmonary artery4–5Hemodynamic monitoring (PAP, PCWP, CO, SVR)

CLABSI Prevention Bundle (CDC/IHI)

The central line bundle has been shown to reduce CLABSI rates by up to 66% when all elements are followed consistently.
Bundle ElementStandardNursing Role
Hand hygieneBefore and after all line access; soap and water or alcohol-based sanitizerModel compliance; speak up if others skip it; never rush this step
Maximal sterile barrier during insertionSterile gloves, gown, mask, cap, full-body drape for patientGather supplies; maintain sterile field; coach patient to turn head; observe for breaks in technique
Chlorhexidine skin antisepsis2% chlorhexidine gluconate in 70% isopropyl alcohol (ChloraPrep); scrub 30 seconds, allow to dry 30 secondsDo not wipe off — allow to dry; if CHG contraindicated (premature infant), use povidone-iodine
Optimal catheter site selectionSubclavian preferred over jugular; avoid femoral when possible (highest infection + DVT risk)Advocate for optimal site; femoral requires extra diligence if used
Daily review of line necessityRemove any line that is no longer clinically necessaryAsk at every patient care round: "Does this patient still need this line?" Document the assessment
Scrub the hub / disinfect needleless connectorsScrub with alcohol for ≥15 seconds before every access; allow to dryScrub every port cap before every access — every single time, no exceptions
Dressing maintenanceTransparent semipermeable (TSM) dressing changed q7 days or when wet/soiled/loose; gauze dressing changed q48hDocument dressing change date/time on dressing; assess site at every shift

Central Line Dressing Change Protocol

Supplies

Procedure

  1. Perform hand hygiene; don mask; have patient put on mask
  2. Don non-sterile gloves; remove old dressing by lifting edges and peeling toward the insertion site (avoids catheter displacement)
  3. Inspect site: redness, swelling, tenderness, exudate, skin breakdown; measure/document catheter external length if applicable
  4. Remove non-sterile gloves; hand hygiene; don sterile gloves
  5. Clean insertion site with CHG applicator using back-and-forth friction for 30 seconds; allow to dry 30 seconds (critical — CHG kills bacteria on drying)
  6. Apply CHG disk (Biopatch) foam side down directly over the insertion site
  7. Apply new securement device if needed
  8. Apply TSM dressing; ensure all edges are sealed; no wrinkles (wrinkles harbor bacteria)
  9. Label dressing with date, time, and initials
  10. Document dressing change, site assessment, and patient tolerance
Never use scissors near central lines — accidental catheter transection can cause air embolism or loss of the line. Use blunt-ended scissors only if required, with extreme caution.

Flushing and Locking Protocols

Line TypeFlush VolumeSolutionFrequency
CVC (active)10 mL NS before and after each useNormal salineBefore/after each use; q8–12h if not in use
PICC (active)10 mL NS; use pulsatile flush (push-pause technique)Normal salineBefore/after each use; q8–12h if not in use
Tunneled CVC (not in use)10 mL NS + heparin lockHeparin 10–100 units/mL per facility policyWeekly or per manufacturer recommendation
Implanted Port (accessed)10 mL NS; de-access with heparin lockHeparin 100–500 units/mL for lockingq4 weeks when not in use; use Huber needle only
Hemodialysis catheterNS, then heparin lock per dialysis protocolHigh-concentration heparin (1,000–5,000 units/mL)After each dialysis session; do NOT use for other infusions without specific order

Troubleshooting Central Line Problems

ProblemLikely CauseNursing Action
Unable to flush (resistance)Clot, fibrin sheath, kinked catheter, positional occlusionCheck for kinks; reposition patient/arm (especially PICC); have patient raise arm, turn head, take deep breath; do NOT force; notify provider; may need TPA (alteplase) per protocol
Sluggish flow / won't infuse at ratePartial occlusion, fibrin sheath, catheter positionAssess for kinked tubing; check dressing (not compressing line); reposition; notify provider; document
No blood returnFibrin sheath, malposition, small lumen, valveFlush first; reposition; if still no blood return, do not use for vesicant medications; notify provider; may need imaging or alteplase
Leaking at insertion siteLoose sutures, catheter migration, split catheterAssess leak source; apply pressure if bleeding; notify provider; do NOT tape over a leaking line and continue use
Patient develops fever, chills, rigors after line accessCLABSI — bacteria entering bloodstream through lineStop all infusions except IV antibiotics; notify provider STAT; obtain blood cultures x2 sets (one from line, one peripheral); expect line removal orders; document all line care events
Air embolism (sudden chest pain, dyspnea, "mill-wheel" murmur)Air entered system during line change or break in systemPosition patient LEFT LATERAL DECUBITUS + Trendelenburg immediately (traps air in right ventricle away from pulmonary outflow); 100% O2; notify provider STAT; this is a medical emergency
