Despite there being many species of jellyfish and venomous marine animals, the first aid and medical treatment of their bites and stings can be grouped simply.
- The use of ice or cold packs will help to reduce the skin pain caused by jellyfish stings.
- Pressure immobilisation bandaging is useful to retain large amounts of venom in one area, reducing absorption into the body until medical treatment is obtained.
- Heat treatment (with hot water) relieves the pain of penetrating spines caused by animals such as stingrays and stonefish.
- Antivenom is available for Chironex box jellyfish, sea snake, and stonefish envenomation.
- Cardiopulmonary resuscitation may be necessary for severe cases of marine envenomation.
