Historical background of I.O. Historical background of I.O. infusions…infusions…• First described by Drinker et al., in 1922.

• In 1941, the method was introduced for clinical use by Tocantis et al., mainly in children.

• Bailey et al. described cannulation of the sternum in 1946.

• Intraosseal regional anesthesia is described by Thorn-Alquist in 1971.

• 2000, recommended for use in the emergency setting by ILCOR.

• Have required a great deal of skill and experience.

• Are not reliable.

• Difficult to use.

• Often not used by medical personnel due to associated psychological barriers.

Introducing the Introducing the B.I.GB.I.G™™……

Adult B.I.G - 15GCE & FDA Approved

Pediatric B.I.G - 18GCE Approved

Design of theDesign of the B.I.G™B.I.G™…… • Developed to be easily used by a single rescuer.

• Allows immediate vascular access.

• Permits the rapid infusion of medications and fluids.

• Minimizes exposure to the patient’s bodily fluids.

• Can be successfully used by physicians and paramedics.

Indications for I.O. infusions…Indications for I.O. infusions…1. TRAUMA

2. NON-TRAUMA

• Fluid replacement in shock.

• Rapid vascular access during mass casualty incidents.

• All cardiac arrests.

• Acute respiratory syndromes (COPD, Asthma, APE).

• When ever rapid vascular access is required.

FROM THE ECC GUIDELINES 2000

Rescuers should increase attention to early vascular access, including immediate Intraosseous access for victims of cardiac arrest, and extend the use of Intraosseous techniques to victims >6 years

Now 2 – 5 cc of bone marrow can be aspirated into a heparin-coated syringe for laboratory sampling, or proceed to inject medications or infuse fluids.

To maintain optimal flow, high pressure, up to 300 mmHg to the infusion bag may be necessary.

Medications and fluids…Medications and fluids…

• All medications and fluids can be safely injected into the B.I.G™.

• I.O. medication and fluid boluses remain the same as those for I.V. injection.

• It is not recommended that large boluses of hypertonic solutions be infused through the I.O. cannula.

• In case of user inaccuracy, or technical malfunction, it is strongly recommended to always have a second B.I.G. On hand.
