Talking about scorpion stings

I. Overview Scorpions are also known as “whole insects” for the class Arachnida, order Scorpion, is a placental arthropod nocturnal carnivore, preferring to grow in drier areas, photophobic. It has a similar venomous organ to that of the snake in the front part of the tail, which can sting humans and other animals. The cephalothorax and anterior abdomen are combined into a carapace, the posterior abdomen is elongated and can be called a tail, with a total of 13 abdominal segments, the end of which is the end of the tail in the form of a sac, which contains white venom and is connected to a hook-shaped venomous stinger, which is a stinging weapon. Sometimes (especially rainy days) poisonous scorpions can enter the home and bed, or hidden in indoor shoes and boots, clothing or wall cracks, mostly accidentally stung by touch, scorpion breeding or scorpion catcher contact opportunities, more likely to be stung. The scorpion’s toxicity varies from species to species, tropical scorpion species and China’s northeast poisonous scorpion, the toxicity is very strong, the northeast poisonous scorpion is equivalent to the eye snake poison, often fatal. The scorpion stabs the skin through the tail sting hook and quickly injects venom into the wound and causes poisoning. The actual toxin is a colorless and transparent toxic protein, acidic, soluble in water, ethanol or ether, and its toxin is neurotoxic, with cholinergic and adrenergic effects, and can interfere with the ion transport of the nerve axon depolarization process, paralyzing the respiratory center, followed by toxins such as hemolysis, hemorrhage, and coagulation. The scorpion sting should be evaluated for criticality by taking into account the following factors: ① the size of the scorpion and the amount of venom injected. The scorpion’s species. ③The manifestation of local and systemic symptoms of poisoning. The actual fact is that you can find a lot of people who are not able to get a good deal on this. The actual scorpion sting is usually a local burning pain, redness, numbness, sensory allergy, and blisters. The first thing you need to do is to get a good idea of what you are getting into. After 1-2 hours of sting, headache, dizziness, photophobia, lacrimation, runny eyes, salivation, nausea, vomiting, bleeding from the nose, lungs or gastrointestinal tract, tonicity of the mouth and tongue muscles, profuse sweating, decreased or increased body temperature, increased and then decreased blood pressure, bradycardia, unfavorable language, irritability, and even convulsions, respiratory paralysis to respiratory failure. Acute heart failure and coma may occur. Occasionally, pancreatitis, elevated blood glucose, proteinuria and hematuria may occur. Rapid development of symptoms within 2 to 4 hours after injury is often a sign of poor prognosis, and death may occur if not properly treated. If the patient survives for more than 48 hours, there is a better chance of cure. Death is most common in children under 6 years of age and often occurs within 2 hours after injury, and the cause of death is mostly severe damage to the vital center. The symptoms of poisoning generally disappear gradually after 2 days, but the nerve damage can last for more than a week. The first aid strategy for scorpion stings is to keep the patient under short-term observation for 4 hours after local wound treatment in mild cases; in severe cases, systemic treatment and admission to the ICU is required. (a) General treatment 1. The patient is sedated and rested in bed. 2. Apply sedative and analgesic drugs. (2) Local treatment of wound 1.Search for and pluck out the caudal spur at the wound (cut open if necessary), and attract the venom by negative pressure. 2.Apply alkaline solution to clean the wound, such as available 5% ~ 10% sodium bicarbonate, 1: 2000 potassium permanganate solution or 3% ammonia to rinse the wound. 3, with 0.25% ~ 0.5% procaine in the wound for circular closure. (C) Other treatment 1, mild local reaction oral antihistamine and analgesic; severe reaction with 1: 1000 epinephrine, 0.3-0.5ml, subcutaneous injection; 10-15 minutes later can be repeated injection. 2, muscle tonic can be used 10% calcium gluconate 10ml, diluted with 5% glucose 20ml intravenously or with xidiazepam 5-10mg intravenously. 3.In severe cases, infuse methylprednisolone 125mg or hydrocortisone 200-300mg intravenously. 4.Prazosin has a peripheral effect of inhibiting toxin, use 0.25 mg orally, 2-3 times daily. 5, give the patient oxygen, acute left heart failure, pulmonary edema can be treated as cardiogenic pulmonary edema, but should not be used morphine, dopamine in shock, should be used in combination with m-hydroxylamine and glucocorticoids, because the toxin has the effect of blocking dopamine receptors, so alone is not effective. All other treatment should be symptomatic. Artificial respiration should be given in case of respiratory distress. 6, the special treatment method is specific anti-scorpion venom serum, but China has not yet produced.
