Immediate access to vascular system Bioavailability is 100% Route for medications and blood and
blood products
For successful cannulation
Proper site selection Proper knowledge of gross anatomy of
veins Identification involves both visual and
tactile exploration The vein may be located as a blue
green subcutaneous structure
Blind attempts are highly unlikely to be successful
Ideally a good sized vein with a straight segment atleast the length of the cannula should be selected
For elective cases
Easy access Non dominant side Avoiding joint areas Avoiding Lower extremities
In UL
Antecubital fossa Forearm Wrist Dorsum of hand Mostly used are cephalic , basilic and
median cubital vein
Veins in the dorsum of the hand can be used if wide bore is not required.
The portion of cephalic vein in the region of radial styloid is often called
Student’s vein or Interns vein
LL
Cannulation is not a good idea It is more painful , more chance of
thrombophebitis
External Jugular Vein
Originates near the angle of mandible and crosses over the stenocleidomastoid
It can accommodate large bore IV catheter
Useful in those with poor access to arms and those who need large volumes of fluids
EJV will be engorged in heart failure patients and thus it is an ideal route for such patients for medications (other veins would be collapsed)
Scalp veins
Central venous access
Central venous pressure monitoring Volume resuscitation Cardiac arrest Lack of peripheral access Infusion of concentrated solutions Placement of transvenous pacemaker Cardiac catheterization, pulmonary
angiography Hemodialysis
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
