Study Notes
Anaphylaxis Overview
- Common triggers include food, medication, latex, and insect venom.
- Diagnosis requires clinical criteria fulfillment after exposure to an allergen.
Acute Treatment
-
IM Epinephrine:
- Administer 0.01 mg/kg (max 0.5 mg) intramuscularly.
- Repeat every 5-15 minutes as needed.
- Use 1:1000 solution (1 mg/mL) in the anterolateral thigh.
-
IV Epinephrine:
- Administer 0.05-0.1 mg IV over 5 minutes.
- Maintain continuous infusion of 2-10 mcg/min adjusted to blood pressure.
- IV solution at 1:10,000 concentration (0.1 mg/mL).
-
Adjunctive Medications:
- H1-Blocker: Ranitidine 50 mg IV every 8 hours as required.
- H2-Blocker: Diphenhydramine 25-50 mg IV every 4-6 hours as needed.
- Steroids: Methylprednisolone 125 mg IV every 6 hours as necessary.
- Glucagon for patients on beta-blockers.
- Salbutamol for bronchoconstriction signs.
- Vasopressors for persistent hypotension.
Discharge Plan
- Prescribe Epinephrine Autoinjector (0.3 mg IM) for emergencies.
- Implement an Anaphylaxis Action Plan including patient education and wearing a MedicAlert bracelet.
- Refer to an Allergist/Immunologist for further evaluation.
Patient-Centered Communication
- Emphasizes understanding socioeconomic and cultural health influences.
- Consent and capacity for treatment require the understanding of treatment nature and consequences.
Consent for Incapable Patients
- Identify a Substitute Decision Maker (SDM) following Ontario’s hierarchy:
- Power of Attorney for Personal Care
- Spouse, common-law partner, or partner
- Parents or adult children over 16
- Siblings and other family members
- Public Guardian and Trustee in case of conflict.
Ethical Considerations in Patient Scenarios
- Considerations include managing patient decisions regarding life-saving therapy, communication of serious diagnoses, and potential family disagreements on treatment choices.
Additional Topics
- Non-Invasive Ventilation indicated for hypoxemia in specific cases; consider situations like respiratory failure or pneumonia.
- For severe traumatic brain injury, guidelines are to assess neurologic criteria following proper timelines, avoiding unnecessary delays.
