Introduction
This learning resource has five components:
1. Before you start - reflection activity
2. Read and Learn
• Indications for insertion of an IO needle
• Safe insertion of an IO needle
• Risks and complications of IO needle insertion
• Which drugs and fluids can be administered through
an IO needle
3. Practical tips
4. Patient safety tips
5. Resource page should you want further information
Before you start
You are involved in the emergency resuscitation of a child
who has presented with probable meningococcal sepsis.
Two senior doctors are trying to get IV access (to
administer antibiotics and volume) but have been
unsuccessful and minutes are passing.
• Would you speak up and suggest an IO should be
inserted?
• Are you confident to do the procedure?
Indications for IO
IO line placement should be considered in
any emergency situation requiring
administration of fluids or drugs where
vascular access has not rapidly been
obtained (2 attempts or >90 seconds)
Indications for IO
To gain emergency vascular access in

Cardiac Arrest
 Deteriorating child




Hemodynamic instability
Respiratory compromise
Altered level of consciousness
Trauma
Thousands of small veins lead from the medullary space to the central circulation
Safe insertion of an IO needle
Equipment:
• Non sterile gloves
• Alcohol swab or dressing pack with
Chlorhexadine skin preparation
• EZ-IO driver and appropriate sized
needle
Designed for 1000 human
insertions
• 5ml & 20ml syringe
• Infusion fluid
Prepare Equipment
EZ-IO Driver
EZ-IO Needle
EZ-Connect
Prepare Equipment
Length and color are the only differences
between paediatric & adult needle sets
Identify site
IO access sites for pediatric patient
Proximal Tibial Anatomy
IO should be inserted 2 cm below tibial tuberosity
(away from growth plate)

Universal precautions
Clean skin at insertion site
Choose appropriate sized needle
Attach needle to driver (magnetic)
Hold needle & driver at 90o to skin and
push needle through skin until bone is
felt (without engaging driver)
Safe insertion of an IO needle
• Engage EZ-IO driver to advance needle
until there is a give / loss of resistance
• Detach driver (magnetic)
• Unscrew trochar
• Attach 5 ml syringe and aspirate
(Aspirate from marrow can be used to check glucose & provide
blood cultures, notify lab of BM specimen if sending any other
blood tests)
• Flush to confirm correct position
• Prime & attach EZ-IO connect
Complications of IO
Contraindications for IO
Extravasation of fluid or
medication
Fracture of bone above IO site
Compartment syndrome
Burn at or above insertion site
Pain -associated with infusion
Cellulitis at insertion site
Osteomyelitis
Osteogenesis imperfect
Growth plate injury
Osteopetrosis
Minor fractures
Inability to locate landmarks or
excessive tissue
Complications of IO - pain
Minimal pain associated with
insertion of EZ-IO
• fast insertion speed
• small insertion site
• vast majority of awake patients
can tolerate insertion without
local anesthetic.
Infusion pain can be severe
• visceral in nature
• diffuse
• can evoke nausea
Which drugs & fluids can be given
All resuscitation drugs, fluids and blood
products can be administered through an IO
Practical Tips
Due to resistance - fluids & drugs need
to be PUSHED through an IO
Patient Safety Tips
IO access provides emergency vascular
access. As soon as possible definitive
venous access should be obtained & IO
removed
