Catheter Occlusion Management
An excerpt from the course material. No account or payment required.
1. Why occlusion matters
Catheter occlusion is the most common non-infectious complication of central vascular access devices (CVADs). Estimates place partial or complete occlusion in as many as one in four catheters at some point during their dwell. The consequences cascade well beyond a slow drip: therapy is delayed or missed, medications are held, catheters are replaced prematurely, and every additional manipulation of the line raises the risk of catheter-related bloodstream infection. Each of those downstream events carries real cost and real patient harm.
The central message of this module is that occlusion is overwhelmingly a preventable complication. The clinician who flushes correctly, locks correctly, respects drug–drug compatibility, and secures the device well will see a fraction of the occlusions of a clinician who does not. When occlusion does occur, a calm, systematic response restores function in most cases without ever removing the catheter.
Diagnose before you treat. Mechanical, thrombotic, and chemical occlusions look similar at the bedside but require completely different interventions. Alteplase will not clear a closed clamp, and repositioning will not dissolve a calcium–phosphate precipitate.
