Contraindications for Using Central Venous Catheters

Central venous catheters (CVCs) enhance puncture success and safety for administering hypertonic solutions or strong acid/alkali drugs. However, certain conditions require caution to avoid complications.

1. Severe Coagulopathy and Infection Risk

Patients with severe bleeding disorders or high infection risk should avoid CVCs, as catheter placement in the superior or inferior vena cava may cause uncontrollable bleeding or worsen infections.

2. Vein Obstruction or Damage

Caution is needed for patients with obstructed or damaged veins, as blockages can hinder catheter insertion, increase puncture failure rates, and risk catheter dislodgement.

3. Inflammation at Puncture Site or Chest Deformities

CVC use is risky if the puncture site (subclavian, jugular, or femoral veins) is inflamed, potentially worsening inflammation or causing adverse reactions, especially in patients with chest deformities.

CVCs reduce complications, allow long-term placement, and simplify care, but caution is critical for patients with coagulopathy, vein issues, or inflammation to ensure safety.
