Central and peripheral line care
Understanding Central and peripheral line care
Central venous catheters — including PICC lines, tunneled catheters, and implanted ports — provide reliable intravenous access for patients who require long-term medication infusions, parenteral nutrition, or frequent blood draws. These lines bypass peripheral veins and terminate in a large central vein near the heart, making proper care essential to prevent serious complications such as bloodstream infections, clotting, and line displacement.
Private duty nurses perform scheduled line maintenance including dressing changes, cap changes, and flushing according to evidence-based protocols. They also assess the insertion site and surrounding tissue at every shift, monitor for early signs of infection or mechanical complications, and educate family members on how to protect the line during daily activities.
What to Expect
Your nurse will perform dressing changes using sterile technique at intervals specified by your physician, typically every seven days or whenever the dressing becomes loose, wet, or soiled. The line will be flushed with saline or heparin as ordered to maintain patency. At each shift, the nurse will inspect the insertion site for redness, swelling, drainage, or tenderness and check that the external line length has not changed.
Protecting Your Line at Home
Keep the dressing clean and dry at all times. Cover the site with a waterproof barrier during bathing as instructed by your nurse. Avoid pulling or tugging on the line, and secure external tubing to prevent accidental dislodgement. Do not allow anyone other than trained clinical personnel to access the line for infusions or blood draws.
When to Contact Your Care Team
Notify the care team immediately if you observe redness, swelling, warmth, or drainage at the insertion site; if the patient develops a fever or chills during or after an infusion; if the line appears to have migrated or become partially dislodged; or if you cannot flush the line. Call 911 if the patient develops sudden chest pain, difficulty breathing, or signs of air embolism such as dizziness and rapid heart rate after a line is accessed or becomes disconnected.
