Anaphylaxis意思
Anaphylaxis is a severe, life-threatening allergic reaction that can occur within minutes of exposure to an allergen. It is a medical emergency that requires immediate treatment. Symptoms of anaphylaxis can include:
- Hives or rash
- Swelling of the face, mouth, or throat
- Difficulty breathing
- Coughing, wheezing, or chest tightness
- Rapid heartbeat
- Dizziness or fainting
- Nausea, vomiting, or diarrhea
Anaphylaxis can be caused by a variety of allergens, including food, medications, insect stings, and latex. It can also occur in response to exercise, cold temperatures, or emotional stress in some people with underlying allergies.
Treatment for anaphylaxis typically involves the administration of epinephrine, which is a hormone that helps to reverse the symptoms of an allergic reaction. Other medications, such as antihistamines and corticosteroids, may also be used to treat the symptoms of anaphylaxis.
It is important for people with a history of severe allergies to carry an epinephrine auto-injector with them at all times, and to know how to use it in case of an emergency. If someone experiences symptoms of anaphylaxis, they should seek medical attention immediately.
