Overview of Emergency Medicine: Definitions and Core Content

Emergency services are provided by medical institutions forSudden, critical illness or traumaEmergency medical services provided to patients, with the core goal ofRapid assessment, stabilization of vital signs, and prevention of condition deterioration. The main content includes the functions of the emergency department (such as triage, rescue), common emergency diseases (such as myocardial infarction, trauma) and medical treatment procedures. In terms of primary and secondary structure, priority is given to explaining the emergencyDefinition and Importance, secondly analyze the characteristics of emergency services (24-hour opening, multidisciplinary collaboration), and finally introduce patient precautions.

Definition and medical characteristics of emergency

Emergency medicine is different from general outpatient clinics. Its core characteristics aretime sensitivity, for potentially life-threatening conditions such as massive bleeding, shock, and acute allergies. Emergency departments are usually equipped withRescue room, monitoring equipmentand a professional team that can perform tracheal intubation, cardiopulmonary resuscitation and other operations within the golden time. For example, the emergency department of Peking Union Medical College Hospital handles an average of 100,000 patients every year, 20% of which arehigh risk cases. Patients need to be sorted according to the severity of their conditions through the triage system to ensure reasonable allocation of resources.

Common emergency symptoms and treatment principles

Common emergency symptoms can be divided intoTrauma(such as broken bones, burns) andMedical emergencies(such as stroke, poisoning). Taking acute chest pain as an example, emergency doctors need to quickly rule out the possibility of myocardial infarction and confirm the diagnosis through electrocardiogram and cardiac enzyme testing. Data show (see table below) that if patients with myocardial infarction are experiencingWithin 120 minutesWith interventional treatment, the survival rate can be increased to more than 90%. In addition, febrile convulsions in children and urgent labor in pregnant women also need priority treatment.

Patient medical procedures and precautions

Emergency medical treatment needs to be followed“Save lives first, treat illnesses later”principle. Patients or family members should clearly describe symptoms (such as pain duration, past medical history), and bring their medical insurance card and list of commonly used medications. Avoid taking up resources for non-emergency situations, such as dispensing medicines for the common cold or chronic diseases. Provided by some hospitalsEmergency green channel(such as the People's Liberation Army General Hospital), giving priority to groups such as military personnel and the elderly. When going to an emergency room at night, you need to pay attention to preventing theft and fraud, and be wary of misleading "medical advice".

Summary: The social value and future direction of emergency care

The emergency system is medically safelast line of defense, reflecting society’s protection of the right to life. With the application of AI triage and remote consultation technology (such as Tencent Miying's emergency assistance system), emergency efficiency will be further improved. The public needs to strengthen their learning of first aid knowledge, such as cardiopulmonary resuscitation (CPR) training, to form a "pre-hospital-in-hospital" linkage. Only when doctors and patients work together can the treatment effect of emergency resources be maximized.
