Indications
- immediate access required for administration of drugs/fluids
- cardiac arrest, resuscitaion when no other IV in place
- IO's should not be left in more than 72-96 h and ideally removed after initial resuscitation once more secured access is achieved[1]
Contraindications
- Osteoporosis
- Osteomyelitis
- steogenesis imperfecta
- Fractured bone
- Recent IO infusion in same bone
- Cellulitis, Infection, or Burn, at insertion site
Equipment
- Multiple different types of IO needles and products available
- EZ-IO drill
- Appropriate IO needle with extension set
- Chloraprep or alcohol to clean skin
- Saline Flush
- Lidocaine (2% lidocaine without epi)
Site Selection
- Proximal Tibia- 2 finger breadths below tibial tuberosity (1-3 cm) on medial, flat aspect of tibia
- Distal Tibia- medial surface at junction of medial malleolus and shaft of tibia, posterior to to greater saphenous vein
- Proximal humerus (adults only, use yellow needle)
- Distal Femur (generally only in infants and children)
- Pelvic ASIS
EZ-IO Needle selection (based on weight of patient)
- Pink 15mm (3-39kg)
- Blue 25mm (40kg and above)
- Yellow 45mm (excessive tissue)
Procedure
- Identify landmarks
- Clean skin
- Place appropriate needle on drill and remove safety cap
- ADVANCE needle through skin to bone
- DRILL needle perpendicular into bone at site with gentle, constant pressure
- When needle tip contacts bone there should be 5mm of catheter visible outside of skin (if not you may need a longer needle)
- Continue drilling through bone until "give" or "pop" occurs and needle tip enters medullary space
- Remove stylet (caution: stylet is extremely sharp - place in sharps container)
- Attach the manuacturer's extension set (helpful if this is pre-flushed with saline and/or lidocaine)
- Aspirate blood/marrow to confirm placement
- If patient is awake, slowly infuse 2% lidocaine (cardiac lidocaine) 2-3mL through the IO line (IO infusion is painful as the marrow cavity expands)
- Flush saline through extension set to expand marrow cavity (helps ensure adequate flow rates)
- Apply dressing
Removal
- Detach extension tubing. Gently and slowly apply in-line traction (i.e. pull straight out - do not rock back and forth). May rotate clockwise while applying in-line traction.
- Can attach syringe via luer lock to act as handle
- Apply dressing.
Complications
- Compartment syndrome
- Incomplete penetration of cortex
- Penetration of posterior cortex
- Infection (cellulitis, osteomyelitis)
- Fracture
- Growth plate damage
- Fat embolism
Labs drawn via IO
- Blood drawn from an IO can be used for type and cross, chemistry, blood gas.
- There is not good correlation with Sodium, Potassium, CO2, and calcium levels.[2]
- Potassium is often elevated due to hemolysis
- CANNOT use IO blood for CBC
- WBCs are higher and platelet counts are lower[2]
IO Medications
- Any medication that can be given in peripheral IV can be given through IO
- Same doses as IV meds
- Follow with flush
- Drips or IV fluids should be given with pressure bag or infusion pump
