Overview
Patients with anaphylaxis usually appear flushed. Physical examination of patients with anaphylaxis is usually remarkable for swollen lips or other areas, wheezing, cyanosis, and low blood pressure. It is vital for the physician to assess cardiac and respiratory symptoms for any compromise as soon as possible. [1]
The diagnosis is likely when any one of the following criteria is met: [2]
- 1. Acute onset with involvement of mucosal tissue, skin, or both and one of the following:
- Respiratory compromise
- Reduced blood pressure or evidence of end-organ dysfunction
- 2. Exposure to a likely antigen for the patient followed by two of the following:
- Skin involvement
- Respiratory compromise
- Reduced blood pressure
- Gastrointestinal symptoms
- 3. Exposure to a known allergen to the patient followed by reduced blood pressure
Physical Examination
Physical examination of patients with anaphylaxis is usually remarkable for flushing and pruritis. The presentation can vary for patients and it is important not to delay treatment. [3] [4] [5] [6] [7] [8]
Appearance of the Patient
- Patients with anaphylaxis usually appear flushed with swollen areas.
Vital Signs
- Low blood pressure
- Rapid pulse or tachycardia
Skin
- Hives
- Skin that is blue from lack of oxygen or pale from shock
- Eczema
- Piloerection
- Warm feeling
Heart
- Abnormal heart rhythm (arrhythmia)
- Palpitations
- Chest pain
Lungs
- Wheezing
- Fluid in the lungs (pulmonary edema)
- Nasal congestion
- Sneezing
- Cough
- Hoarseness
- Rhinorrhea
- Dyspnea
Neurologic
Other
- Swelling (angioedema) in the throat that may be severe enough to block the airway
- Swelling of the eyes or face
- Weakness
- Nausea or vomiting
- Abdominal pain
- Diarrhea
- Anxiety
The health care provider will wait to test for the specific allergen that caused anaphylaxis (if the cause is not obvious) until after treatment.
