Anaphylaxis is a severe, potentially life-threatening allergic reaction. Symptoms typically emerge within minutes of exposure to an allergen and peak within the first two hours, though in some cases they can extend up to 4-6 hours.
Key signs and symptoms include:
* Skin Reactions: Hives (urticaria), itching, rash, redness, swelling (face, lips, tongue, throat).
* Respiratory System: Difficulty breathing, coughing, wheezing, hoarseness, a sensation of throat constriction, runny nose, sneezing.
* Cardiovascular System: Low blood pressure (hypotension), increased or decreased heart rate, dizziness, fainting.
* Digestive System: Nausea, vomiting, abdominal pain, cramps, diarrhea, urinary incontinence.
* Neurological Symptoms: Dizziness, fainting, fatigue, weakness.
In anaphylaxis, at least two organ systems are typically affected. Although skin manifestations are the most common, approximately 10% of cases may not show any skin symptoms. Involvement of the respiratory and cardiovascular systems indicates a life-threatening condition. Isolated symptoms like rapid onset hoarseness, a feeling of throat constriction, or low blood pressure after exposure to a known allergen (e.g., bee sting or medication use) can also indicate anaphylaxis. Symptoms can vary in the same person at different times and with different triggers.
Should preparation be made for the TEE examination?
