Background

Template:CVC main points

Types

Depths

  • All +/- 2 cm
  • Right IJ - 13 cm
  • Right subclavian - 15 cm
  • Left IJ - 15 cm
  • Left subclavian - 17 cm

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

Flow rate depends on diameter and length of IV; the Hagen–Poiseuille equation.[4]

PIV

  • 16G IV: 13.2 L/hr
  • 18G IV: 6.0 L/hr
  • 20G IV: 3.6 L/hr

Central Line

  • 5 Fr PICC/Port: 1.75 L/hr
  • 7 Fr TLC 16G distal port: 1.9 L/hr
  • 7 Fr TLC 18G proximal port: 3.4 L/hr
  • 12 Fr HD: 23.7 L/hr
  • 8.5 Fr Cordis/introducer sheath: 7.6 L/hr
  • 8.5 Fr Cordis/introducer sheath with pressure bag: 20.0 L/hr

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
