Femoral anatomy
 Vein is medial to the
artery
– Froehlich’s theorem
 Superficial distal to
inguinal ligament, then
dives deep
 0.5-2cm inferior to the
inguinal ligament
Quiz Question
 What are the anatomic landmarks to determine
where to stick for the femoral vein in a pulseless
patient?
– A. 1/3 of the distance from the anterior superior iliac spine
to the pubic tubercle
– B. ½ the distance between the pubic tubercle and the
anterior superior iliac spine
– C. 1/3 of the distance from the pubic tubercle and the
anterior superior iliac spine
– D. None of the above
Quiz answer
 D. None of the above
 The femoral ARTERY lies ½ the distance
between the pubic tubercle and the anterior
superior iliac spine.
 The femoral vein is 0.5-1.5 cm medial to this
depending on the size of the patient.
Straight vs. Frog leg
 “The optimal positioning
of the leg can vary
according to the
preference of the
operator.”
– Discuss
Procedure
 30-45 degree angle to skin
 2 methods
– Stick with negative pressure
on syringe while entering
and exiting
– Insert needle, and only
negative pressure on
removal
 Allows you to better
stabilize the needle by
resting your hand on the
thigh
Procedure
 Blood flash - Insert wire
– Wire not going smoothly
 Needle no longer in vessel
 False tracking in subcutaneous tissue
 Thrombus
 Advancing into lumbar veins
 Small incision
– Blade directed away from wire
Procedure
 Twisting motion of dilation
 Remove dilator
 Advance catheter
 Remove wire
 Aspirate and flush all ports
 Secure line with sutures
 Sterile dressing
Seldinger Technique
Procedure
 Wheeler – “Confirmation of proper CVC
position is required after placement of all
CVC’s”
Warnings
 If you hit the artery – pressure until hemostatic
 Wire should float – should never have resistance
 If can’t pull the wire through the needle – remove
both wire and needle together so you don’t sheer off
the wire
 Never let go of the wire
 Catheter tip “pointing too cephalad” – in lumbar veins
Complications
 74 of 89 (83%) – no complications
 Other 15 – minor bleeding/hematoma
 94.4% success rate
 Median duration 5 days
– 21% <3 days 26% 7-14 days
– 43% 4-7 days 10% >14 days
 Long term – 8 leg swelling, 11 BSI
Venkataraman, et al. Clin Ped 1997;36:311-9.
Complications
 45 months – 395 CVL – 162 femoral
 No insertion complications
 Mean duration 8.9 days
 9 noninfectious complications
– 4 thrombosis, 1 perforation, 1 embolism, 2 bleeding
 “The low incidence of complications in this study
suggests that the femoral vein is the preferred site in
most critically ill children when CVC is indicated.”

Femoral  Easy access
 Large vessel
 Good access
during
resuscitation
 Decreased
mobility
 Increased risk
of thrombosis,
phlebitis &
infection
 Easily
contaminated
 Close to
femoral artery
 Dressing
difficult to
maintain
Subclavian Vein
 When to use it
– May be better for long term access
– Obese – clavicle gives you a landmark
– Shock – less likely to collapse
 Relative contraindications
– Trauma to the area
– Coagulopathic
Subclavian Anatomy
 Begins as axillary vein,
eventually joins the IJ
to become the
inominate or
brachiocephalic
 Anterior scalene
separates the SCA from
SCV
 Most common is
infraclavicular approach
Positioning
 Head down 15-30
degrees
 Rolled towel placed
longitudinally between
scapulae
 Tilt head toward side of
catheterization
– Reduced catheter
malposition in infants
Quiz Question
 What is the anatomic landmark on the
clavicle where you insert the needle?
– A. 1 cm below the junction of the middle and
lateral thirds of the clavicle
– B. 1 cm below the junction of the middle and
medial thirds of the clavicle
– C. 1 cm below the middle third of the clavicle
– D. 1 cm below the lateral third of the clavicle
Quiz Answer
 What is the anatomic
landmark on the
clavicle where you
insert the needle?
– B. 1 cm below the
junction of the middle
and medial thirds of the
clavicle
Procedure
 Needle inserted 1 cm below
junction of middle and
medial thirds of the clavicle
 Marched down clavicle and
parallel to frontal plane
 Bevel directed caudal
 Blood flash during insertion
or withdrawal
Procedure
 Regular Seldinger
technique
 Watch for dysrhythmias
with wire insertion
Confirmation
 Position should be in
the distal SVC
 FDA – “the catheter tip
should not be placed in
or allowed to migrate
into the heart”
 34% mortality rate with
CVC related pericardial
effusions in pediatrics
Complications
 Inability to cannulate
 SCA puncture/cannulation
 Catheter misplacement
 Pneumothorax
 Hemothorax
 Nerve injury
Complications
 100 patients - 1/3 of patients <1 year

Subclavian  Large vessel
 Can tolerate
high flow
 Dressing easy
to maintain
 Less
restrictive for
patient
 Lowest sepsis
rate
 Close to lung
apex, risk of
pneumothorax
 Close to
subclavian
artery
 Hard to control
bleeding
Internal Jugular Vein
 When to use it
– High rate of success
– Compressible if coagulopathic
– Lung hyperinflation (less likely to get
pneumothorax than subclavian)
– Transvenous pacing via RIJ
 Relative contraindications
– Ongoing CPR – difficult to access
– Cervical trauma/increased ICP
Internal Jugular Anatomy
 Lateral to carotid artery
in sheath
 Beneath the triangle
formed by the sternal
and clavicular heads of
the SCM and the
clavicle
Quiz Question
 All of the following are correct about a left internal
jugular cannulation EXCEPT:
– A. LIJ has a more acute angle at connection with
subclavian
– B. Lower pneumothorax risk compared to right because
right pleural dome is higher
– C. Lymphatic duct adjacent to junction of LIJ and
innominate vein
– D. Reduced risk of carotid puncture because of its caudo-
cephalad structure
Quiz answer
 B is the correct answer to the question
 Reasons to go right –
 The left has :
– More acute angle at connection with subclavian
– Left pleural dome is higher (more pneumothorax
risk)
– Lymphatic duct adjacent to junction of LIJ and
innominate
Internal Jugular Positioning
 Trendelenberg 15-30
degrees
 Shoulder roll
 Head turned away from
side of insertion
Procedure – Median approach
 Needle insertion –
approximately one half
the distance between
the mastoid and the
sternal notch
 20-30 degree needle
angle
 Seldinger technique –
watch for dysrhythmias
Posterior Approach
Anterior Approach
Procedure
 Finder needle
techniques
– Consider when:
 Poor landmarks (obese)
 Coagulopathic
 Carotid artery disease
in adults
 Ultrasound

    Quiz Question  Allof the following are correct about a left internal jugular cannulation EXCEPT: – A. LIJ has a more acute angle at connection with subclavian – B. Lower pneumothorax risk compared to right because right pleural dome is higher – C. Lymphatic duct adjacent to junction of LIJ and innominate vein – D. Reduced risk of carotid puncture because of its caudo- cephalad structure
  • 72.
    Quiz answer  Bis the correct answer to the question  Reasons to go right –  The left has : – More acute angle at connection with subclavian – Left pleural dome is higher (more pneumothorax risk) – Lymphatic duct adjacent to junction of LIJ and innominate
