Central venous catheterization

Revision as of 18:12, 3 July 2015 by Neil.m.young (talk | contribs) (added info - flow rate, complications)

Types

Indications

  • Central venous pressure monitoring
  • Administration of multiple medications and drips
  • High volume/flow resuscitation[citation needed]
  • Emergency venous access
  • Inability to obtain peripheral venous access
  • Repetitive blood sampling
  • Administering hyperalimentation, vasopressors, caustic agents, or other concentrated fluids
  • Insertion of transvenous cardiac pacemakers
  • Hemodialysis or plasmapheresis
  • Insertion of pulmonary artery catheters

Contraindications

Absolute[1]

  • Infection over the placement site
  • Anatomic obstruction (thrombosis of target vein, other anatomic variance)
  • Site-specific
    • Subclavian - trauma/fracture to ipsilateral clavicle or proximal ribs

Relative

  • Coagulopathy (see below)
  • Distortion of landmarks by trauma or congenital anomalies
  • Prior vessel injury or procedures
  • Morbid obesity
  • Uncooperative/combative patient

Central line if coagulopathic

  • Preferentially use a compressible site such as the femoral location (avoid the IJ and subclavian if possible, though IJ preferred over subclavian)
  • No benefit to giving FFP unless artery is punctured[2]

Flow Rates

PIV

  • 16G IV: 220 ml/min
  • 18G IV: 105 ml/min

Central Line

  • Cordis/introducer sheath: 126 ml/min
  • 16G distal port TLC: 69 ml/min
  • PICC/Port: varies by gauge

Complications

Complications vary by site

  • Pneumothorax (more common with subclavian)
  • Arterial puncture (more common with femoral)
  • Catheter malposition
  • Subcutaneous hematoma
  • Hemothorax
  • Catheter related infection (historically more with femoral)
  • Catheter induced thrombosis
  • Arrhythmia (usually from guidewire insertion)
  • Venous air embolism (avoid with Trendelenburg position)
  • Bleeding
