At present, venomous snake bites are still a common disease in our countryside. Early diagnosis and treatment is directly related to the patient’s life and safety. The author found that in the process of clinical treatment of snakebite there are still some misunderstandings, seriously affecting the patient’s prognosis, worthy of attention. Misunderstanding one, once the respiratory arrest, large doses of respiratory stimulants Bitten by neurotoxic venomous snakes, the serious condition of the patient will often appear shallow and slow respiration, or even respiratory arrest. The main reason for this situation is that snake venom blocks the transmission of neuromuscular junction. Respiratory stimulants not only have no antagonistic effect, but also increase the body’s consumption of energy and oxygen. Therefore, respiratory paralysis after a venomous snake bite is primarily a matter of solving the problem of respiratory muscle power – early ventilatory support. Only when the patient’s respiratory function is gradually restored and weak breathing occurs, the moderate use of respiratory stimulants will help the recovery of the patient’s voluntary respiration, otherwise it is counterproductive. Myth two, antivenom dosage, antivenom effect is good antivenom antivenom is currently recognized at home and abroad as a potent drug against snake venom. Its mechanism of action is to neutralize the free snake venom that has not been combined with the target organ, preventing the snake venom from continuing to cause damage to the human body. Clinical practice and animal experiments have confirmed that the earlier the treatment with it, the better the effect. The therapeutic dosage should be sufficient, which in principle means that the dosage of antivenom should exceed the amount of snake venom injected at the time of being bitten, in order to completely neutralize the toxicity of snake venom entering the body. Therefore, the dosage of antivenom should depend on the amount of venom injected into the snake bite. In practice, however, this amount is difficult to determine, and it is generally believed that a single antivenom is sufficient to neutralize the venom of a venomous snake. Recently, foreign countries have advocated the use of small doses of antivenom, which is considered to be harmful if the dose is too large. Myth three, pregnant women were bitten by a venomous snake, can not apply antivenom Some people are afraid of antivenom to pregnant women and the fetus have an impact, and do not dare to apply antivenom to pregnant women. Snake venom (neurotoxin, blood circulation venom, mixed venom) and antivenom products on the fetus whether there is damage, which is domestic and foreign snakebite prevention and treatment of the field of a research hot spot. Current research believes that the main toxic substances in snake venom do not directly affect fetal development through the placental barrier, but snake venom can cause respiratory failure, renal failure, hemorrhage, hemolysis, DIC, etc. in pregnant women. Complications of snake venom can cause intrauterine distress, leading to miscarriage, preterm labor, stillbirth, and even death of mother and baby. Research has also proved that antivenom products with high purity, strong neutralizing power and few side effects are safe and effective drugs for treating snake bites in pregnant women, and the key is to use sufficient quantities of targeted antivenom as early as possible. The key is to use a sufficient amount of targeted antivenom as early as possible. Myth 4: When children are bitten by poisonous snakes, the dose of antivenom should be less than that of adults Antivenom is effective in the treatment of venomous snake bites, and its mechanism lies in the fact that antivenom can neutralize toxins that are not combined, and early application of a single antivenom will be able to neutralize the toxins released from a corresponding venomous snake. Therefore, the dose of antivenom is the same for the elderly, children, the infirm and healthy adults. It is wrong to arbitrarily reduce the dose of antivenom for the elderly, children and the infirm. Myth five, the use of pro-coagulant drugs Some patients bitten by five-paced snake or viper, often appear wound bleeding or systemic bleeding phenomenon, and even hemorrhagic shock. At this time, the application of pro-coagulant drugs, such as hemostatic minerals, 6-amino acid (EACA), or transfusion of fresh blood, it is often difficult to achieve the desired purpose of hemostasis, or even aggravate the bleeding. This is because these venomous snakes contain thrombin-like enzyme components and hemorrhagic toxins. Among them, thrombin-like enzyme components can directly act on fibrinogen, turning it into fibrin, which in turn triggers consumptive coagulation disorders. The hemorrhagic toxin can destroy the capillary wall and its intercellular mucus, causing bleeding by increasing the permeability of the capillary wall. Input of fresh blood before complete removal of snake venom toxins will likewise be destroyed by snake venom and will not serve to replenish blood volume. The correct treatment method is to apply sufficient amount of antivenom, adrenocorticotropic hormone and vitamin C static drip, for bleeding wounds, can be used with norepinephrine-soaked gauze external dressing, external bandage with pressure. Blind application of anticoagulant drugs is not helpful.
