Intraosseous Needle Insertion Kalpesh Patel, MD Dept. of Pediatric Emergency Medicine November 22, 2006 Objectives Understand the history of intraosseous needles (IO) Understand the indications, risks, and benefits of IO needle insertion Learn to perform: • IO needle insertion at various locations using the manual insertion method • IO needle insertion using new techniques 2 History Earliest reference to IO use was in 1922 First theraputic use in humans was reported in 1934 Popularized in the 1940’s for rapid access Used widely until 1950’s when the plastic catheter was devised Reemerged in mid 80’s for resuscitation where IV access was difficult Since then, pediatric use has become more accepted Now used as the standard of care for emergency access in both pediatrics and adults 3 Physiology The marrow cavity is in continuity with the venous circulation and functions as a non-collapsable venous plexus Sinusoids serve as transport to the central venous channel exiting as nutrient and emissary veins 4 Physiology The onset of action and drug levels during CPR using the IO route are similar to those given IV • Used to infuse fluids, blood products, and drugs • Can take mixed venous blood samples for labs such as crossmatch, bedside tests, etc. 5 Indications When vascular access is needed in life-threatening situations When attempts at standard venous access fail (three attempts or 90 seconds) or in cases where it is likely to fail and speed is of the essence. 6 Contraindications Femoral fracture on the ipsilateral side Do not use fractured bones Do not use bones with osteomyelitis Osteogenesis Imperfecta Osteopetrosis 7 Types of IO Needles Jamshidi IO Needle Cook IO Needle 8 Illinois Sternal Iliac Needle Sur-Fast IO Screw Tip Needle Equipment Required Antiseptic prep solution Local Anesthetic (optional in the moribund patient) IO Needles • 18-20 gauge spinal needle can be used as an alternative • In a pinch, any needle can be used, but may get clogged with cortical bone without stylet or trochar Syringe Flush solution Gauze pads and tape 9 Locations of Insertion 3 most common locations: • Proximal Tibia Medial side, 1-2 cm below and avoiding the tibial tuberosity 10 Locations of Insertion Distal Femur • Femur is triangular shaped. Insert needle 1-2 cm proximal to the superior border of patella and medial or lateral to anterior ridge Distal Tibia • 1-2 cm proximal to the medial malleolus in the center of the bone 11 Locations of Insertion In older children and adults: • Iliac crests, preferably Anterior Superior Iliac Spine • Sternum 12 Technique for Manual Insertion Prep the site Inject 1-3 ml of lidocaine into the skin and down to the periosteum (optional when time does not permit this) Grasp needle in dominant hand and place it on the site with the needle pointing away from the joint Pinch needle with thumb and forefinger and allow the hub to rest in the palm of your hand DO NOT PLACE YOUR OTHER HAND BENEATH THE SITE 13 Technique for Manual Insertion Use firm downward pressure and rotate the needle back and forth Feel for a sudden decrease in resistance or a popping sound and advance the needle a few millimeters Remove the trochar or stylet and aspirate marrow 14 Technique for Manual Insertion Infuse fluid to determine ease of flow and no extravasation in to soft tissues around the insertion site Secure the needle with goal post taping to allow visualization of the site If the needle fails, then insert into a new bone because fluid will leak from the failed site 15 IO Insertion http://www.cookmedical.com/cc/datasheetMedia.do?mediaId=1528&id=1347 Complications Through and through penetration • Extravasation of fluids or medications into subcutaneous tissue Compartment syndrome Subcutaneous abscess/skin necrosis Osteomyelitis • When an aseptic technique is used, the incidence of osteomyelitis is less than 1% Bacteremia Epiphyseal injury and fracture (especially in neonates) Fat Embolus Bent needle Complications are reported to occur in <1% of cases 17 New Methods F.A.S.T -1 system Bone Injection Gun (BIG) EZ-IO Drill 18 F.A.S.T. -1 Sternal Intraosseous Device First Access for Shock and Trauma Created for insertion into manubrium of adult sternum May be used in older children http://www.pyng.com/movies/iousemovie .html 19 Bone Injection Gun Spring loaded catheter injected into place at a preset depth Comes in Adult and Pediatric sizes Establishes access within 1 minute 20 BIG, The Movie http://www.ps-med.com/big/description_big01.html EZ-IO A battery powered electric drill which places the needle quickly into place 22 EZ-IO Insertion http://www.vidacare.com/Products/index_4_29.html Aftercare IO’s are emergency lines and every effort should be made to place an intravenous line after initial resuscitation IO’s should ideally be removed within 6-12 hours All IO’s will eventually start to leak IO’s can stay in for up to 48-72 hours, but after 24 hours the risk of osteomyelitis increases dramatically 24 Summary IO’s are essentially equivalent to IV access Should be used for emergency access Many types of needles exist, but Jamshidi style is preferred by most users Preferred insertion sites include proximal or distal tibia, or distal femur, but in older children, iliac crests and sternum can be considered New devices are emerging, but are not standard of care in pediatrics yet 25 Questions? 26
