  • 20 gauge - 60 ml/min - Most infusions, rapid fluid, trauma
  • 22 gauge - 36 ml/min - Most infusions, rapid fluid, paediatrics/elderly

• Secure
• Flush w/ 10 ml NS

IO:

• Common locations of insertion:
  • Tibial plateau (2 cm below knee)
  • Humerus head
• Other locations:
  • Distal femur
  • Clavicle
  • Radius 
• Needle sizing
  • Red cap - paediatric 
  • Blue cap - normal adult
  • Yellow cap - longer adult (difficult locations, i.e. distal femur)
• Attempt IV
• Palpate area of insertion, rule out deformities 
• Sterilise w/ chlorhexidine 
• Attach selected size to drill
• Re-palpate location, placing finger over site
• Place needle where finger was, and plunge into the bone
• Activate drill, drilling down until cap fills with flesh
• Remove drill
• Attach syringe, draw back bone marrow
• Flush w/ NS
• Secure cap

EJVA: 

• Attempt IV, IO
• Tilt head to side and away from intended site 
• Identify jugular vein
• Sterilise between neck and collarbone w/ chlorhexidine 
• Drape incision area
• Locally anesthetise using lidocaine, leave 1 cc in syringe 
• Take 12 gauge needle w/ 1 cc lidocaine
• Insert needle at 18 degrees towards heart
• Advance until it hits jugular vein, shown through aspiration of lidocaine 
• Detach syringe, thread guide wire through needle
• Remove needle, hold guide wire steady 
• Make a small incision moving away from the wire with an 11 blade 
• Take the dilator and thread it over the guidewire, pushing it down as far as it can go, then remove it 
• Threat the central line over the guidewire, remove the guidewire
• Flush each port w/ 5 ml saline, clamp off, secure line
