The Australian Pressure Immobilisation method of First Aid

This method of first aid was developed after clinical and laboratory experience showed that most venom seemed to be transported from the bite site, to the rest of the body, in lymphatic vessels. The technique is designed to slow or stop flow in lymphatic vessels in the bitten limb. It can only be used on limbs, NOT on the body, neck or head. While local pressure over the bite site, then the rest of the bitten limb is an important part of the first aid, it is probably immobilisation of the bitten limb which is crucial to the success of this first aid technique.

In Australia, where venom detection from the skin is an important hospital test, it is vital that the bite area is not washed of cleaned in any way.

The technique for pressure immobilisation first aid is as follows:

If the bite is on a limb, a broad bandage (even torn strips of clothing or pantyhose) should be applied over the bitten area at moderate pressure (as for a sprain; not so tight circulation is impaired), then extended to cover as much of the bitten limb as possible, including fingers or toes, going over the top of clothing rather than risking excessive limb movement by removing clothing. The bitten limb should then be immobilised as effectively as possible using an extemporised splint or sling.
