What to do with the jellyfish philosopher

Jellyfish is an invertebrate that lives in the ocean, which is what we often call jellyfish. Most people have only seen jellyfish sold in seafood markets, but they don’t know that jellyfish can also sting people. Jellyfish have many milky white tentacles, which they use to find food and, of course, to attack the outside world. Jellyfish also grow in places where we often swim, so we must be more careful. If you are stung by a jellyfish, take effective measures in time. We recommend several good methods below.

1. Jellyfish dermatitis (also known as jellyfish dermatitis) is a disease that occurs with the arrival of summer. There are a large number of stinging cells on the tentacles of jellyfish, which contain venom, the main components of which are protein-like substances, polypeptides and a variety of toxic enzymes, as well as strong anesthetics, analgesics, histamine, etc. When the human body comes into contact with the tentacles of jellyfish, the cnidocytes can penetrate the skin and cause cnidocyte dermatitis, which can even lead to death in severe cases.

When a swimmer's exposed limbs are stung by a jellyfish, he or she will feel tingling, burning pain or itching, followed by the appearance of cord-like erythema and papules at the sting site, and may also have blisters, bullae, petechiae and ecchymosis. In mild cases, the rash may disappear within 1-2 days, and in most patients, the rash will scab over and heal within 1-2 weeks. If stung in multiple places on the body or by large jellyfish or highly poisonous jellyfish, people often experience chills, fever, abdominal pain, fatigue, cold sweats within 1-4 hours. A few people may experience chest tightness, foaming at the mouth, low blood pressure, difficulty breathing, and pulmonary edema. In severe cases, it can lead to death.

Once stung by a jellyfish, do not rinse with fresh water, as fresh water can induce the nematocysts to release venom. The tentacles or venom adhering to the skin should be wiped off as soon as possible with a towel, clothes, mud and sand, or rinsed with sea water. If conditions permit, you can rinse or spray the affected area with alcohol or alkaline lotion, such as 10% sodium bicarbonate. Patients with large skin lesions and severe systemic reactions should go to the hospital for treatment in time.

2. 1. Immediately scrub the wound with sea water or sand in the water to clean off the poisonous stinging cells remaining on the skin. If conditions permit, use a towel.

2. Go ashore quickly and apply saturated alum solution, alkaline solution or alkaline paste, 10% sodium hydroxide solution (the alkali commonly used to make rice porridge at home), diluted ammonia water, toothpaste, soap, urine, etc. on the wound.

3. After getting ashore, be careful not to expose the wound to sunlight, because the toxins of the jellyfish will be released more rapidly when exposed to sunlight, and the stimulation of the sunlight to the wound will also cause more pain.

4. After returning home, take anti-allergic drugs orally, vitamin C tablets or apply some anti-allergic ointment.

5. Try to avoid contact of the wound with fresh water until the symptoms disappear, as fresh water can cause pain and intensify the release of jellyfish toxins.

6. If the wound becomes itchy, please do not scratch it. Be sure to endure it and apply some alkaline solution or alkaline paste. Just apply it.

7. If there is no improvement within one week, go to the hospital for examination and treatment.
