Most common late complication of central venous line or PICC?
Appeared in: NORCET 5 Prelims - Sept 2023 (Shift-1)
Explanation
Sepsis or infection.
Central lines provide a direct route for microorganisms to enter the bloodstream. Over days to weeks, the catheter can become colonized, leading to a catheter-related bloodstream infection (CRBSI).
This risk increases the longer the catheter remains in place, making infection the most common and serious late complication.
Late complications are defined as those occurring after the first few days of catheter placement.
Why Other Options Were Wrong
Option A: Phlebitis, or inflammation of the vein, is typically an early complication. It often results from mechanical irritation during insertion or chemical irritation from the infused solution.
Option B: Air embolism is an acute, potentially life-threatening event that occurs when air enters the venous system. It is associated with procedures like insertion, removal, or disconnection of the line, making it an immediate or early complication, not a late one.
Option C: While thromboembolism (formation of a blood clot) is a significant risk and can occur as a late complication, catheter-related bloodstream infection (sepsis) is generally considered the most common late complication for long-term central lines.

Clinical Relevance
Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Complications of Central Venous Access Devices (CVADs) as background academic context rather than a clinical decision trigger.
Preventing catheter-related bloodstream infections (CRBSIs) is a top patient safety priority and a key nursing responsibility. These infections increase patient morbidity, mortality, length of stay, and healthcare costs.
Nurses must meticulously follow evidence-based 'central line bundles,' which include strict hand hygiene, use of maximal barrier precautions during insertion, chlorhexidine skin antisepsis, avoiding the femoral site in adults, and daily review of line necessity.
What if? - If a patient with a PICC line develops a fever, chills, and hypotension, the nurse's first priority is to suspect sepsis. The immediate actions would be to notify the provider, prepare for blood cultures to be drawn (from the line and a peripheral site), and anticipate orders for broad-spectrum antibiotics and potential line removal.
How to Approach the Question
First, identify the key terms in the question: 'most common,' 'late complication,' and 'central venous line/PICC.'
The term 'late' is critical. It directs you to think about complications that develop over time, not immediately after insertion.
Evaluate each option based on its typical time of onset.
Consider Phlebitis and Air Embolism. These are generally acute or early events related to the insertion procedure or mechanical/chemical factors.
Consider Thromboembolism and Infection. Both can be late complications. However, the prolonged presence of a foreign body (the catheter) provides a surface for microbial colonization, making infection a very common issue the longer the line is in place.
Conclude that sepsis/infection is the most well-known and frequent late complication associated with long-term central venous access.
