📚 Central Line Bundle — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
The central line bundle is a set of evidence-based practices that, used together, dramatically reduce central line-associated bloodstream infections (CLABSI). It spans insertion and maintenance. Core elements: hand hygiene, maximal sterile barriers at insertion, chlorhexidine skin antisepsis, optimal site selection, and daily review of line necessity.
🔑
Key points
Understand these first
The five core elements are hand hygiene, maximal barrier precautions, chlorhexidine skin prep, optimal site selection, and daily necessity review.
Maximal sterile barriers at insertion include cap, mask, sterile gown, sterile gloves, and a full-body sterile drape.
Chlorhexidine is the preferred skin antiseptic and must dry fully before insertion.
The subclavian site generally carries lower infection risk than femoral; femoral is avoided when possible.
Scrub the hub and needleless connectors before each access (scrub the hub).
Removing the line as soon as it is no longer needed is a key infection-prevention step.
✅
Nursing priorities
What to do, in order
Perform hand hygiene and ensure full maximal sterile barriers during insertion.
Prep the skin with chlorhexidine and allow it to dry completely before insertion.
Scrub the hub or connector with antiseptic before every access.
Assess line necessity daily and advocate removal when no longer needed.
Maintain a sterile occlusive dressing and change it per protocol or when soiled or loose.
🚩
Red flags — report now
Escalate immediately
Never skip maximal sterile barrier precautions for a central line insertion.
Do not leave a central line in place once it is no longer clinically needed.
Report redness, drainage, or fever, which may signal a bloodstream infection.
🧪
Labs & values
Numbers to know
Blood cultures (peripheral and from the line) to diagnose CLABSI
WBC: normal 5,000-10,000 cells/mm3; elevation may indicate infection
🗣️
Patient teaching
What patients must know
Keep the dressing clean, dry, and intact and report if it loosens or gets wet.
Report fever, chills, or redness and tenderness at the insertion site.
