scorpion sting
Introduction
Introduction to bruises belongs to the arachnid, the eye. There are about 300 kinds of individuals, and the size of the individual is very large. The size is only 1~2cm, and the larger one can exceed 20cm. It is a viviparous birth, and the young cubs leave the mother's independent free life in about one week to find various insects. Distributed throughout the world, China is more common in the north. The venom gland contains a strong acidic venom, which is a neurotoxin, a hemolytic toxin and an anticoagulant. If a person is stabbed, these toxins can be injected into the human body, causing dermatitis and poisoning symptoms. Immediately after the bruise is found, the tourniquet should be used to tighten the wounded proximal heart or place an ice pack to reduce the absorption and spread of toxins. Milk or cupping should try to suck out the venom. If necessary, expand the wound. Immediately rinse with soapy water or 5%~10% dilute ammonia solution (ammonia) or 1:5000 potassium permanganate solution, then use 5% baking soda. The solution is applied wet, and then the alkali powder is applied to the affected area with 5% to 10% dilute ammonia solution to neutralize the acidic venom juice, relieve the pain, and irritating drugs such as iodine are prohibited in the wound. basic knowledge The proportion of sickness: 0.01% Susceptible people: no Mode of infection: non-infectious Complications: pulmonary edema
Cause
Cause of bruise
(1) Causes of the disease
The venom gland contains a strong acidic venom, which is a neurotoxin, a hemolytic toxin and an anticoagulant. If a person is stabbed, these toxins can be injected into the body, causing symptoms of dermatitis and poisoning.
(two) pathogenesis
The scorpion is hidden in the dark and damp bricks, stone gaps, woodpile and clothing, shoes, and often come out to find food at night. If people touch the scorpion, they will be stabbed by the poisonous hook at the tail. The last section is sharp. It is a hedgehog that communicates with the venom gland on the dorsal side of the abdomen. The venom gland contains a strong acidic venom, which is a neurotoxin, a hemolytic toxin and an anticoagulant. If the person is stabbed, these toxins can be injected into the body, causing dermatitis. And symptoms of poisoning.
Prevention
Bruise prevention
Preventing scorpions should first do a good job of indoor and outdoor environmental sanitation, clear bricks, stones, weeds and dead leaves, so that the scorpions have no habitat, and the night activities are illuminated by lights or flashlights to prevent direct touch of walls in the dark, indoor and outdoor scorpions. When the density is high, the residual spraying treatment can be performed. To go to the woods in the mountains, wear long-sleeved clothes, tie the cuffs, trouser legs, gloves, and carry emergency medicine if necessary.
Complication
Bruise complications Complications pulmonary edema
A small number may have urinary closure, pulmonary edema, confusion, and finally paralysis and death.
Symptom
Symptoms of bruises common symptoms, ecchymosis, dizziness, skin necrosis, dysphagia, difficulty, drowsiness, urinary palpitations, blood pressure drop
Depending on the type of scorpion and the length of the stab wound, it is generally said that the wild hawthorn is more toxic than the home. Once it is severely painful after being licked, some may feel hot and stinging, and then a significant redness or swelling occurs at the wound. Blisters, ecchymoses, severe skin necrosis, lymph nodes or lymphatic inflammation, which is caused by hemolytic toxins, and the other is that skin symptoms are not serious, but the symptoms of systemic poisoning are obvious, which is due to the rapid neurotoxin Severe systemic reactions caused by central nervous system and vascular system, such as dizziness, headache, fever, nausea, vomiting, salivation, tearing, palpitations, lethargy, cyanosis, shortness of breath, excessive sweating, laryngeal edema, difficulty swallowing, blood pressure drop, Reflex sputum, a small number may appear urinary closure, pulmonary edema, mental confusion, and finally respiratory paralysis and death, especially if children under 5 years of age are injured by the mountain, they can quickly develop severe systemic symptoms, can die within 3 hours, Therefore, it is necessary to carry out the rescue in time.
If the skin is suddenly bitten by poisonous insects in a dark and humid place or at night, severe redness of the skin or symptoms of systemic poisoning should consider the possibility of being bruised. It is found that the body can be diagnosed.
Examine
Bruise check
According to the clinical manifestations, significant redness or blisters and ecchymoses occur immediately in the wound. In severe cases, skin necrosis, lymph nodes or lymphatic vessels may be inflamed, which is caused by hemolytic toxins. The other is that the skin symptoms are not serious, but the symptoms of systemic poisoning are obvious. This is due to the severe systemic reaction caused by the neurotoxins acting on the central nervous system and the vascular system. The poisoning is serious, and dizziness, headache, lethargy, and salivation may occur. , photophobia, tearing, nausea and vomiting, strong mouth and tongue muscles, sweating, shortness of breath, weak pulse and muscle spasm. Most of the severe poisoning is for young children, and even nose, lung or sputum hemorrhage, pulmonary edema, coma, and respiratory and circulatory failure are life-threatening.

diagnosis
According to the cause, the clinical manifestations can be diagnosed.
Differential diagnosis
The injury is related to the bee sting: the bee sting usually only shows local redness and pain, and it will subside after a few hours without systemic symptoms. If the bee stings remain in the wound (a small black spot is visible in the center of the redness), sometimes localized can cause suppuration. If it is injured by a bee colony, systemic symptoms such as dizziness, nausea, vomiting, severe shock, coma or rapid death may occur; some may cause hemoglobinuria, and even acute renal failure. Allergic patients can develop urticaria, edema, asthma or anaphylactic shock even with a single bee sting.
