40 people in 2 hours to the hospital! Recently go to Dalian beach to play can be careful of it!
In August and September, we Liaoning people like to go to the beach to cool off or play, and many of them will choose to go to Dalian Beach!
If you have this plan recently, then when you go to play, you should pay attention to the fact that in just two hours on the evening of August 4, the Emergency Dermatology Department of the First Affiliated Hospital of Dalian Medical University received more than 40 patients who were stung by jellyfish. Jellyfish are found in the Xiajiahezi Sea, the Great Black Rock Sea, the Fujiazhuang Sea and the sea near Lushun North Road. Why are jellyfish poisonous?
The body of the jellyfish is divided into two parts – the umbrella and the mouth and wrist. The mouth and wrist, which we call the jellyfish head, have eight mouth wrists, and under them are filamentous, gray-red, and the venom-secreting tentacles are located in this part. The surface of the jellyfish's tentacles is covered with venom-secreting spiny sacs, and at the outer tip of each stinging sac there is a needle-shaped trigger, which catapults out as soon as the external stimulus touches the trigger, injecting the venom onto the surface of the contact's body for defensive or predatory purposes. Jellyfish poison is 450 times more poisonous than pufferfish It is well known that eating puffer fish meat will cause death due to poisoning, but jellyfish poison is much more powerful than puffer fish poison.
Studies have shown that jellyfish toxins are 250 times more toxic than sea snake toxins and 450 times more toxic than tetrodotoxin. Sea wasp jellyfish, spiny silk sacs can secrete cobra-like venom, the most harmful to humans, after stinging 5 minutes can cause death. "What if I get hurt by a jellyfish?" Let's first understand the performance after being stung by jellyfish, which can be divided into local symptoms and systemic symptoms. Symptoms of jellyfish stings: Mild stings appear as local skin symptoms, and in severe cases, systemic symptoms may occur. Local symptoms of sting sites may appear: burning, dry stinging, itching, local skin gradually appear linear arrangement of erythema, wind mass; in severe cases, redness, blisters, ecchymosis and even epidermal necrosis can appear. Lesions generally last 3 to 14 days, some can last up to several months, and generally do not leave scars and pigmentation. Systemic symptoms are: cough, chest tightness, shortness of breath, dyspnea and other pulmonary edema manifestations, headache, dizziness, irritability, limb numbness and other neurological manifestations, as well as nausea, vomiting, abdominal pain, diarrhea and other digestive system manifestations, and even arrhythmias, hypotension, shock and so on.
How should I give first aid in the event of a jellyfish sting? Jellyfish generally do not actively attack people, but jellyfish tentacles that touch people will wrap around the human body, release toxins, and float in the sea of dead jellyfish, may also sting people. First of all, when playing with the sea, try to observe the surrounding environment, generally larger jellyfish are more toxic, but also easier to find. If jellyfish are found, they must not be touched, let alone caught. Secondly, do a good job of personal protection, wear swimwear that covers a large area of the body, and can also avoid large damage to the skin in the event of jellyfish. If you are accidentally stung by a jellyfish, then: 1. Remove residues, rinse with seawater to remove the residue with towels and clothing (can not be used directly by hand), and then rinse with seawater, do not rinse with fresh water, so as not to stimulate the further release of toxins and aggravate the situation. 2. Rapid medical conditions allow you to rinse with 5% to 10% sodium bicarbonate (i.e., baking soda) or alum water, and then use sodium bicarbonate solution for cold compresses; you can also use calamine lotion to apply externally, hormone ointment for external use, and then immediately go to the hospital for treatment. Playing on the beach in the summer seems harmless but hides the "killing machine" people should pay more attention
