Cnidarians (Cnidaria, Like Jellyfish And Sea Anemones)

Among the cnidarians (Cnidaria) include coral sea anemones Jellyfish (including Sea Nettles) Hydrozoa (. Eg Portuguese Man) cnidarians are responsible for more poisonings than any other toxic seafood. Of the 9,000 species but only about 100 are poisonous to humans. Cnidarians have highly developed hives devices (nematocysts, nematocysts) which can penetrate the human skin. Particularly numerous, the nematocysts are on the tentacles of these animals. A tentacle can discharge thousands of nematocysts during contact, which penetrate the skin. Symptoms and complaints The lesions vary depending on the type of nettle animal. Typically, the initial lesion of small, arranged in a plurality of broken lines and quickly shooting up papules that are sometimes surrounded by an erythema. Typically, a severe itching is added. Pain occurs immediately and can be very strong. The papules develop into pustules and blisters, it can eventually lead to skin hemorrhages and detachment of the skin. occur on general symptoms: weakness, nausea, headache and muscle pain, muscle spasms, lacrimation, nasal discharge, increased sweating, heart rate changes and pleuritisch-related chest pain. Occasionally fatal injuries occur by jellyfish from the family of box jellyfish: in North American waters in particular by the Portuguese galley and Indo-Pacific waters by the sea wasp (Chironex fleckeri). Therapy removing tentacles Symptomatic therapy Various rinses for the treatment of pain and for deactivating nematocysts, whichever animal was the cause When stitches by nettle jellyfish the adhesive tentacle with tweezers removed (preferably, otherwise with double gloved fingers) extensively and the affected area rinsed to remove the invisible, stinging cells. The type of flushing depends on the sharp organism: In jellyfish injuries in non-tropical waters and coral stitches sea water can be used for rinsing. In jellyfish injuries in tropical waters should be sustainable rinsed with vinegar and then with sea water. With fresh water should not be washed because unfired nematocysts are thus only fired. In box jellyfish (Cubozoa) vinegar relieves burning the nematocysts and is used as a first rinse, if available. Then rinsed with seawater. With fresh water should not be washed because unfired nematocysts are thus only fired. In the Portuguese galley and salt water can be used. Vinegar should not be used here because it may enable not fired nematocysts. Any form of shortness of breath or alteration of consciousness, no matter how slight, is a medical emergency and requires transport to a medical center and possibly an injection of epinephrine. Otherwise, there are only symptomatic therapy. Pain of sea nettle injuries are usually short-lived, they can through the application of baking soda in a 50: 50 be alleviated solution. In other stitches or contacts hot water or ice, whichever feels better, relieve pain, as well as an NSAID or other painkillers. For severe pain, opioids can be given. The muscle pain and muscle spasms can be treated with benzodiazepines. Infusions and epinephrine can be given when a shock develops. There is an antivenin for the poison of the box jellyfish C. fleckeri (sea wasp), but not for violations by the North American species. Sea Bader rash The Marine Bader rash occurs in some swimmers who bathed in the Atlantic off Florida, the Caribbean or Long Iceland. It is caused by a hypersensitivity to engravings of the larvae of sea anemone (z. B. Edwardsiella Lineate) or thimble jellyfish (Linuche unguiculata). The rash appears where the swimsuit touches the skin. People who had contact with these larvae should take off her swimsuit after the bath and shower. Skin lesions can be treated with hydrocortisone lotion and, if necessary, with an oral antihistamine. More severe reactions may require the addition of oral or intravenous prednisone.
