Study Notes
Allergic Response Symptoms
- Mild allergic reactions may present with symptoms such as sneezing, itching, and mild swelling.
- Moderate symptoms can escalate to hives, shortness of breath, and gastrointestinal issues.
- Anaphylaxis is a severe, life-threatening allergic reaction characterized by difficulty breathing, rapid heart rate, and a drop in blood pressure.
Immediate Treatment for Chemical Ingestion
- If a dry powder chemical that causes burning is ingested, the immediate step is to rinse the mouth thoroughly with water.
- Avoid inducing vomiting unless advised by a medical professional, as this can worsen the chemical's effect.
Contraindications for Epinephrine
- Potential contraindications for administering epinephrine include significant heart disease or acute coronary syndrome.
- History of hypertension may also warrant caution in epinephrine use during anaphylaxis.
Exacerbation of Cardiac Conditions
- Administration of epinephrine can potentially exacerbate underlying cardiac conditions, leading to arrhythmias due to its stimulant effect on the heart.
Symptoms Indicating Severe Allergic Reactions
- Signs of a severe allergic reaction indicating systemic inflammatory mediator release include difficulty breathing, swelling of the throat, and rapid drop in blood pressure.
- Other symptoms may include severe abdominal pain and loss of consciousness.
Activated Charcoal Administration
- Activated charcoal should be administered under specific circumstances, such as within one hour of ingestion of a toxic substance that is not caustic.
- It is generally not indicated for corrosive substances.
Anaphylaxis vs. Anaphylactic Shock
- Anaphylaxis refers to the overall severe allergic reaction, while anaphylactic shock is a critical manifestation where there is a significant drop in blood pressure and organ dysfunction.
- Anaphylactic shock is a more severe outcome of an untreated anaphylaxis condition.
Symptom Not Associated with Anaphylaxis
- A symptom not typically associated with anaphylaxis is a fever, as this condition is characterized by rapid onset of allergic symptoms rather than infectious or inflammatory responses.
Primary Role of Epinephrine
- The primary role of epinephrine in treating anaphylaxis is to reverse the effects of severe allergic reactions by constricting blood vessels, dilating airways, and increasing heart rate.
Route of Epinephrine Administration
- Epinephrine is typically administered via intramuscular injection, often in the mid-anterolateral thigh for quick absorption.
Dosage of Epinephrine for Children
- The appropriate epinephrine dosage for a child experiencing severe allergic reactions is generally 0.01 mg/kg, with a common auto-injector device delivering 0.15 mg or 0.30 mg based on age and weight.
Indication for Using Epinephrine
- The general indication for using epinephrine in a medical emergency is the presence of anaphylaxis, where the patient exhibits severe allergic symptoms that require immediate intervention.
