Student presentation for PDHPE class.

1. Laura Ball Bites and Stings

2. Nature of medical condition/injury Bites and stings are directly related to the venom which is injected into the body. The different types of venom of bites and stings varies according to the diverse range of venomous creatures such as snakes, spiders, bees, wasps, scorpions, ants, ticks, jellyfish, molluscs and fish. Since every venomous creature is different the severity of the bites and stings will depend on characteristics such as the type of creature, strength and effect of creature, the amount of venom injected, as well as on characteristics of the casualty such as their size, age and general health. A specific person characteristic of a person is allergies. Although some venoms may be recognised as minor bites/stings if a person has an allergic reaction to the venom they may go into anaphylactic shock which in turn can be fatal, also depending on the severity of the allergic reaction.

3. Spread Of Venom There are two ways that venom can be circulated throughout the body, by the circulatory and/or lymphatic system. The lymphatic system works by muscular action and the only way to slow down the spread of venom via the lymphatic system is to use the Pressure-Immobilisation technique as well as minimising movement of affected limb. Prevention With bites and stings what is better than a treatment is prevention. A person can do this by avoiding or taking special care in areas and seasons prone to venomous creatures (such as long grass for snakes, etc) and by treating the creatures with respect such as sea creatures, etc.

11. Pressure-Immobilisation technique lymphatic system, which works by muscular action. In order to slow down venom circulation for these specific creatures the pressure-immobilisation technique should be used. The venoms of snakes, blue-ringed octopus, cone shell and Funnelweb Spider circulate through the body via the Immediately apply pressure to envenomed area . Apply broad pressure bandage Bandage should be tight and firm but not too mush as to stop circulation. Start from below bite and work you way up. Apply bandage as far up limb as possible. Apply a splint to limb to inhibit movement. Fasten splint to limb using another bandage. Bind splint as firm as possible to restrict all movement. Then seek urgent medical assistance. When the arm is the site of affected area, after applying above steps a sling should also be used to immobilise the limb. Pictures from: AVRU (Australian Venom Research Unit).
