scorpion sting
Introduction
Introduction to scorpion sting The scorpions are mainly distributed in the tropics and subtropics. There are many species and the toxicity varies. The virulence of oriental toads in China is equivalent to cobra venom, which can be fatal. The scorpion has a pair of venom glands and tail thorns. When puncturing, the venom enters the human body through the tail hook. The scorpion venom is a low molecular weight, colorless toxic protein. The main toxic effect is neurotoxicity: cholinergic and adrenergic effects; there is still hemolysis, hemorrhage Poison and other effects, and can cause acute pancreatitis and high blood sugar. The neurotoxin binds to the sodium channel of the nerve cell, which enhances the presynaptic activity of the neuromuscular junction, parasympathetic nerve, adrenergic nerve endings and adrenal medulla. There is a poisonous thorn in the tail of the scorpion. When the scorpion venom discharges the venom, it can cause poisoning. The scorpion venom is a toxic protein, scorpion toxin, which has a paralyzing effect on the respiratory center and has a stimulating effect on the cardiovascular system. In severe cases, it can be fatal. In addition, bleeding and hemolysis can occur, occasionally causing pancreatitis and increased blood sugar. basic knowledge The proportion of illness: 1% Susceptible people: no specific population Mode of infection: non-infectious Complications: premature beats, coma, pulmonary edema
Cause
Causes of scorpion injury
It is commonly known as scorpion, which has many types of toxic substances, and some of them are not completely toxic. When scorpions are smashed, their venom is injected into the wound, which can quickly cause toxic reactions.
Prevention
Scorpion bruise prevention
1. To prevent the damage of scorpion, we should first do a good job of indoor and outdoor environmental sanitation, remove bricks, stones, weeds and dead leaves, so that scorpions have no habitat.
2. Night activities are illuminated by lights or flashlights to prevent direct touch of the walls in the dark.
3. When the density of indoor and outdoor tweezers is high, it can be treated with residual spraying.
Complication
Scorpion bruise complications Complications, premature coma, pulmonary edema
Severe cases of shortness of breath, chest tightness, tachycardia or slow, weak pulse, premature beat, elevated blood pressure, stun, coma, respiratory depression, pulmonary edema or concurrent disseminated intravascular coagulation, and even death.
Symptom
Scorpion bruise symptoms common symptoms tears severe pain edema hematuria twitching blood sugar rise dizziness paralysis sleepiness bradycardia
General scorpionsting, local burning, numbness, redness, blisters or bleeding, no systemic symptoms, but can be dizzy, headache, general malaise, bradycardia, sweating, oliguria , lethargy, muscle pain, cramps, convulsions, gastrointestinal bleeding and respiratory central paralysis, or hypotension and pulmonary edema.
Severe pain often occurs frequently in the local area of the stab wound, lasting for several minutes to 24 hours, but often no obvious redness, systemic symptoms are more common in children, the disease progresses rapidly, there are tears, runny, sweating, muscle spasm, high blood pressure, etc., severe cases Myocardial injury, heart rhythm disorder, shock, pulmonary edema, and even paralysis may occur, with elevated blood glucose, diabetes, hematuria, black feces, and even diffuse intravascular coagulation.
Examine
Scorpion bruise inspection
There may be proteinuria, hematuria and diabetes.
Diagnosis
Diagnosis and diagnosis of scorpion scorpion
diagnosis
It can be diagnosed based on medical history, clinical symptoms and laboratory tests.
Differential diagnosis
Identification of snake bites: If the wound has a pair of toxic tooth marks, accompanied by local and systemic symptoms, and if the snake body or wounded proves to be a viper, it is mostly a snake; if the wound has 2-4 rows of even and fine tooth marks, No local symptoms or local symptoms are mild, no systemic local symptoms, mostly non-toxic snakes.
Identification with bee sting: The main components of bee venom are formic acid, neurotoxin, histamine, some bee venom can cause hemolysis and hemorrhage, mainly manifested as red, swollen, painful, sometimes fever, headache after bruise Etc., allergic to bee venom can occur systemic urticaria, allergic shock, throat sputum, etc., but no local tooth marks, combined with the injured environment or medical history can be identified with snake bites.
Identification with bite marks: scorpion venom contains toxic components similar to bee venom, such as histamine-like substances, hemolytic proteins, etc., clinical manifestations of local redness, swelling, pain, or local lymphangitis and tissue necrosis, the body may have fever, Headache, nausea, vomiting, etc., or allergic shock, no local tooth marks, can be distinguished from snake bites.
