„ Potential Complications
OVERVIEW
† Minimum of two large caliber IVs (1416 Gauge)
† U/E peripheral IV preferred
† When establishing IV, blood should
be drawn
† Avoid veins that drain from neck
trauma, into an affected traumatic
extremity, or the side of a chest or
abdominal trauma
U/E Peripheral IV - Anatomy
† Success of cannulation depends on
knowledge of anatomy
† Antero-Radial side forearm – Cephalic
vein
† Ulnar posterior forearm – Basilic vein
–easily accessed if elbow flexed and
cannulator stands at head of patient
U/E Peripheral IV - Anatomy
† Antecubital veins – Medial Cubital,
Basilic, Cephalic
† Easily cannulated – but restricted
elbow motion
† Above elbow – larger Basilic and
Cephalic veins – more difficult to see
U/E Peripheral IV - Anatomy
L/E Peripheral IV - Anatomy
† Dorsal venous arch splits into the
greater saphenous vein medially and
the lesser saphenous vein laterally
† Greater saphenous vein most easily
accessible at the ankle, but may also
be cannulated below the knee and
below femoral triangle
L/E Peripheral IV - Anatomy
† Greater saphenous vein passes 1 cm
anterior to medial malleolus where it
lies next to the periosteum
L/E Peripheral IV - Anatomy
External Jugular Vein
† Formed below the ear and behind the
angle of the mandible, passes
obliquely across the
sternocleidomastoid, under the
middle of the clavicle to join the
subclavian vein
† Presence of valves
† Flow dependent on neck position
External Jugular Vein
Materials Required for Peripheral IV
Line Insertion
†
†
†
†
†
†
†
†
Alcohol pads
Tourniquet
Gauze
Tegaderm
Intravenous catheter
1-in tape
¼-in tape
Gloves
Inspection and Positioning
† Place a 1 inch tourniquet on the
upper arm
† Palpate with index and middle fingers
of nondominant hand
Tourniquet
Cannulation
† Clean site with Alcohol
† Stabilize the vein – position thumb
alongside vein and pull down. Place
index finger more cephalad and push
upward
† Agiocath between thumb and
forefinger of dominant hand, bevel
up, angled 10-30 degrees, parallel to
vein
Cannulation
† When flash is seen, advance catheter a few
millimeters more to ensure it has entered
vein, not just wall
† Loosen stylet - advance catheter only
† Occlude vein at tip of catheter, remove
needle, attach IV line, release tourniquet
† Blood samples may be drawn at this time
Cannulation
Securing the IV
External Jugular Cannulation
† Place patient in Trendelenberg to fill
External Jugular
† Rotate head to opposite side
† Align cannula in the direction of the vein
with point aimed toward ipsilateral shoulder
† Puncture midway between angle of jaw and
midclavicular line, lightly compressing the
vein above the clavicle
Complications - Peripheral IV
†
†
†
†
†
†
Phlebitis
Extravasation
Nerve Damage
Air Embolism
Bruising
Thrombosis
Phlebitis
† Presence of palpable cord
accompanied by warmth, erythema,
tenderness, and induration
Extravasation
† Infiltration relatively minor and
common complication of IV therapy
† If infusions hypertonic, vasopressors
or chemotherapies – risk of skin
sloughing
† If dopamine or norepinephrine
extravasates, phentolamine may be
used as antidote – skin injected with
small aliquots of 50:50 dilution
Extravasation of Phenytoin
Air Embolism
† Significant, but rare
† Symptoms of Chest pain, SOB,
Sudden vascular collapse, Cyanosis,
Hypotension
† If suspected, place pt in LLD with
head and chest tilted downward
Central Lines
† Subclavian
† Internal Jugular
† Femoral
Subclavian Vein - Anatomy
† Continuation of axillary vein at outer
edge of first rib
† Joins IJ to become innominate vein 34 cm proximally
† Valveless
† After crossing first rib, lies posterior
to the medial third of the clavicle
† Anterior scalene muscle is posterior
to vein, anterior to subclavian artery
Subclavian Vein - Anatomy
† Phrenic nerve runs over anterior
surface of scalene and immediately
behind the junction of subclavian and
IJ veins
† Thoracic duct (L) and lymphatic duct
®, pass over anterior scalene muscle
and enter subclavian near junction
with IJ
Internal Jugular - Anatomy
† Emerges in neck deep to posterior
belly of digastric muscle
† At origin, courses adjacent to spinal
accessory, vagus, and hypoglossal
nerves as well as internal carotid
artery
† Tributary veins enter IJ at level of
hyoid bone
Internal Jugular - Anatomy
† IJ, ICA, and Vagus nerve course
together in carotid sheath…..IJ is
antero-lateral
† Lateral & slightly anterior to carotid
† Level of thyroid cartilage, IJ just deep
to SCM
† Emerges from under apex of triangle
of two heads of SCM
† Joins subclavian behind clavicle
Internal Jugular - Anatomy
† Lower cervical region, carotid deep
paratracheal location
† Brachial plexus separated from IJ by
scalenus anterior
† Phrenic nerve anterior to scalenus
anterior muscle
† Stellate ganglion anterior to lower
brachial plexus
Femoral Vein - Anatomy
† Just medial to the femoral artery
below inguinal ligament
† Beneath lies psoas muscle and hip
† As progress more distal, femoral vein
becomes posterior to femoral artery
† NAVEL
Seldinger Technique
† Thin walled needle used to access
vessel lumen
† Once introducing needle positioned in
vessel lumen, guidewire is threaded
through the needle and needle
removed
† Wire serves as guide over which
selected catheter placed.
Seldinger Technique
† Introducing needle large enough to
accommodate guidewire is attached
to a small syringe.
† Needle and syringe introduced
together
† When free return of blood, remove
syringe, stabilize needle hub
† Cap needle hub with thumb to
decrease risk air embolism
A. Cannulate vessel
Seldinger Technique
† Flexible end of guidewire threaded
through the needle
† Wire should thread smoothly through
vein without resistance
† If resistance met, remove wire from
needle and reattach syringe to
confirm intravascular placement
† If resistance to wire removal, wire &
needle should be removed together
Seldinger Technique
† If threading easily, advance guidewire
until at least one quarter in vessel
† Once wire in vessel, remove needle
† Make small skin incision at site of
wire. Incision should be width of
catheter to be inserted and extend
completely through the dermis
B. Thread wire through vessel
C. Remove needle
D. Enlarge skin entry with #11
scalpel
Seldinger Technique
† Stabilize guidewire at point of skin
entry and thread dilator/sheath over
wire until 1 cm from skin
† Before dilator/sheath enters skin,
wire must protrude out back of dilator
† Wire must be grasped as
dilator/sheath advanced
† If wire not protruding from prox end
of dilator, pull at skin entry point
E. Catheter sheath and dilator
threaded over wire
F. If prox wire not visible, pull from
skin through catheter until out back
H. Once sheath and dilator well
into vessel, remove dilator and wire

angle to the sternal end of the
clavicle (toward finger placed in
suprasternal notch)
Subclavian, Infraclavicular
Approach
† Slowly advance the needle while
gently withdrawing the plunger of the
syringe
