Central venous catheterCentral venous catheterCentral venous access is the placement

of a venous catheter in a vein that leads directly to the heart.

Relative Contraindications Relative Contraindications Bleeding disordersAnticoagulation or thrombolytic therapyDistorted local anatomyCellulitis, burns, severe dermatitis at siteVasculitis

Technique Technique Seldinger technique◦ Use introducing needle to locate vein◦ Wire is threaded through the needle◦ Needle is removed◦ Skin and vessel are dilated◦ Catheter is placed over the wire◦ Wire is removed◦ Catheter is secured in place

Basic PrinciplesBasic PrinciplesDecide if the line is really necessaryKnow your anatomyBe familiar with your equipmentObtain optimal patient positioning and cooperationTake your timeUse sterile techniqueAlways have a hand on your wireAsk for helpAlways aspirate as you advance as you withdraw the needle

slowlyAlways withdraw the needle to the level of the skin before

redirecting the angleObtain chest x-ray post line placement and review it

Location Advantage Disadvantage

Internal Jugular

• Bleeding can be recognized and controlled• Malposition is rare• Less risk of pneumothorax

• Risk of carotid artery puncture• PTX possible

Femoral • Easy to find vein• No risk of pneumothorax• Preferred site for emergencies and CPR• Fewer bad complications

• Highest risk of infection• Risk of DVT• Not good for ambulatory patients

Subclavian • Most comfortable for conscious patients

• Highest risk of PTX, should not do on intubated pts• Should not be done if < 2 years• Vein is non-compressible

Subclavian Approach Subclavian Approach Positioning◦ Right side preferred◦ Supine position, head neutral, arm abducted◦ Trendelenburg (10-15 degrees) ◦ Shoulders neutral with mild retraction

Needle placement◦ Junction of middle and medial thirds of clavicle◦ At the small tubercle in the medial deltopectoral groove◦ Needle should be parallel to skin ◦ Aim towards the suprasternal notch and just under the clavicle

Internal Jugular ApproachInternal Jugular ApproachPositioning◦ Right side preferred◦ Trendelenburg position◦ Head turned slightly away from side of venipuncture

Needle placement: Central approach◦ Locate the triangle formed by the clavicle and the sternal and

clavicular heads of the SCM muscle◦ Gently place three fingers of left hand on carotid artery◦ Place needle at 30 to 40 degrees to the skin, lateral to the carotid

artery◦ Aim toward the ipsilateral nipple under the medial border of the

lateral head of the SCM muscle◦ Vein should be 1-1.5 cm deep, avoid deep probing in the neck

Internal Jugular Central Approach

Femoral ApproachFemoral ApproachPositioning◦ Supine

Needle placement◦ Medial to femoral artery ◦ Needle held at 45 degree angle ◦ Skin insertion 2 cm below inguinal ligament◦ Aim toward umbilicus

Complications Complications Vascular◦ Air embolus◦ Arterial puncture◦ Arteriovenous fistula◦ Hematoma◦ Blood clot

Infectious◦ Sepsis, cellulitis, osteomyelitis, septic arthritis

Miscellaneous ◦ Dysrhythmias◦ Catheter knotting or malposition◦ Nerve injury◦ Pneumothorax, hemothorax, hydrothorax,

hemomediastinum◦ Bowel or bladder perforation

Tips Tips After 3-4 tries, let someone else tryGet cheast x-ray after unsuccessful attempt If attempt at one site fails, try new site on same side to

avoid bilateral complicationsHalt positive pressure ventilation as the needle penetrates

the chest wall in subclavian approach If you meet resistance while inserting the guide wire,

withdraw slightly and rotate the wire and re-advanceAlign the bevel with the syringe markingsWithdraw slowly, you will often hit the vein on the way out
