POINTS & PEARLS
A Quick-Read Review Of Key Points & Clinical Pearls, June 2017
Vascular Access in Pediatric Patients in the Emergency
Department: Types of Access, Indications, and Complications
• Remember Poiseuille’s law when choosing equipment for intravenous (IV) access. For situations
requiring rapid fluid administration, the widest and
shortest equipment should be selected.
• Consider the duration of treatment, indication for
treatment, type of solution, vein availability, and
patient age when selecting the type and location of
• The difficult intravenous access (DIVA) score
can be used to predict which children will have
difficult IV access. A DIVA score ≥ 4 identifies
patients who need extra consideration before IV
• When placing a peripheral IV catheter, consider
using device-assisted access such as ultrasound or a
VeinViewer® or AccuVein®.
• Solutions with a pH < 5 or > 9 or those with an
osmolarity > 600 mOsm/L can cause damage if not
contained in a peripheral vein.
• If an intraosseous (IO) line cannot be placed in the
proximal tibia, other options include the distal tibia,
the distal femur, the distal end of the radial bone,
the proximal metaphysis of the humerus, the sternum, the calcaneus, the iliac crest, the clavicle, and
the lateral or medial malleolus.
• Do not place an IO needle in newborns weighing
< 1000 g, unless there are no other options for obtaining access.
• Laboratory results from an IO sample may vary
compared to peripheral samples; in particular,
carbon dioxide tension may be lower, white blood
cell counts may be higher, and platelet counts may
• An IO line may be left in place up to 96 hours; however,
it is preferable that it be removed within 6 to 12 hours.
• For both internal jugular and subclavian nontunneled
catheter access attempts, the right side of the patient is
preferable, due to a lower complication rate.
• Femoral lines have the highest risk of infection compared with internal jugular and subclavian catheters.
• Although implantable ports have a lower infection
rate compared to other catheters, they are associated with extravasation and thrombosis.
June 2017 • Pediatric Emergency Medicine Practice
For patients with difficult access, an IV nursespecialist or alternative IV access methods
(eg, ultrasound-guidance) should be used (if
available) for the first attempt rather than as a
Abandon peripheral IV access placement after
2 failed attempts that last more than a total of
In patients with peripherally inserted central
catheters, blood cultures should be drawn from
a separate venipuncture site to reduce the rate of
false-positive blood cultures via contamination.
Use of pain control strategies in pediatric patients increases first-attempt success rates and
• Umbilical vein catheters should be inserted only
to the point of blood return (usually 4-5 cm).
• The saphenous vein is the safest access point for
venous cutdown in a pediatric patient. The incision should be made 2 fingers-breadth cephalad
to the medial malleolus.
• For excessive postdialysis bleeding due to heparin administration in a hemodialysis line, use 1
mg of protamine IV per 100 units of heparin. If
the heparin dose is unknown, administer 10 to 20
mg of protamine IV.

What change(s) do you anticipate making in
your practice as a result of this activity?
The sum of point values of the variables noted is the DIVA score (range,
A DIVA score ≥ 4 indicates that extra consideration may be needed
before placing a peripheral intravenous catheter.

I’m going to calculate DIVA scores for my
patients and use transillumination prior to
attempting peripheral intravenous access.
I will be more careful with my peripheral
I’ll use a J-tip when appropriate and reconsider EMLA.
