Emergency Treatment Guidelines: Classification and Identification of Shock, Emergency Positioning, and Anti-allergic Emergency Management

Shock is a critical emergency that can be caused by many factors. It is primarily a syndrome characterized by impaired microcirculatory blood flow, leading to insufficient blood supply to various organs throughout the body. Patients may experience a range of clinical symptoms and signs. Early symptoms include palpitations, dizziness, pallor, cold sweats, rapid heart rate, and decreased blood pressure. This is followed by lethargy, rapid breathing, cold and clammy extremities, and a further drop in blood pressure. Severe cases may result in coma, undetectable blood pressure, a further increase in heart rate, and cyanosis. Without timely treatment, death is imminent. Anaphylactic shock is a very common type of shock, often caused by allergic reactions to certain medications, transfusions of incompatible blood, or certain serum preparations. Anaphylactic shock is particularly common with penicillin. Patients may also experience shock due to severe trauma or serious illness, such as cardiogenic shock from acute myocardial infarction, septic shock from severe infectious diseases, and hemorrhagic shock from massive gastrointestinal bleeding. Managing shock patients is a highly complex medical challenge. Different types of shock require different treatment principles. Shock patients should be transferred to a hospital as soon as possible. For shock caused by trauma, immediate hemostasis, bandaging, and pain relief should be administered. Except for head and chest injuries, morphine or pethidine can be used for pain relief, and the patient should be positioned with their head lower than their feet to ensure adequate blood supply to the brain. If there are head or chest injuries, the head should be appropriately elevated or the patient should be placed in a supine position; this is the basic treatment for shock. If possible, immediately administer intravenous fluids, adding 1-2 ampoules each of dopamine and metaraminol (Aramine) to 100-200 ml of normal saline, and closely monitor blood pressure. For shock caused by other reasons, emergency treatment should target the underlying cause. For shock caused by penicillin allergy, immediately administer 0.5-1 mg of adrenaline intramuscularly, or 5-10 mg of dexamethasone (flumethasone) intramuscularly or intravenously. For shock caused by severe infection, poisoning, or heart disease, the primary disease must be treated simultaneously.
