  1. Anaphylaxis and Epinephrine The Role of the EMT-Basic N.H. Patient Care Protocols N.H. Department of Safety Division of Fire Standards & Training and Emergency Medical Services

  2. Goals • Overview of General Pharmacology • Review the signs & symptoms & types of allergic reactions • Review of emergency care of a patient experiencing an anaphylactic reaction • Develop a basic knowledge of epinephrine & it’s administration • Identify situations when epinephrine may be indicated • Understand NH Patient Care Protocol - Anaphylaxis

  3. General Pharmacology • For every medication you may administer, you must thoroughly understand the following: • Actions • Indications • Contraindications • Dosage • Route • Side effects

  4. Generic name Original chemical name Trade name Brand name given by manufacturer General Pharmacology

  5. General Pharmacology Medication Forms • Solutions • Liquid mixture of one or more substances • Other forms • tablets, suspensions, vaporized, gels, etc.

  6. General Pharmacology • Right Patient • Right Drug • Right Dose • Right Time • Right Route • Right Documentation

  7. What Is Medical Control? Off-Line / Standing Orders Online Medical Control • contact with an emergency department physician at the receiving facility NH Patient Care Protocols • “Minimum” menu - Saf-C 5900 • “Maximum” menu - Medical Control Board • Scope of Education v. Scope of Practice

  8. Very Common Range from mild and local to severe and systemic. Allergic Reactions

  9. Common Causes of Allergic Reactions

  10. Mild Allergic Reactions • Mild reactions usually affect only one area of the body • Slow onset, and minor symptoms (i.e. localized redness, swelling, itching) • NO respiratory or cardiac signs or symptoms

  11. Mild Allergic Reactions A mild, local reaction caused by a bee sting

  12. A Clear History of Allergen Exposure AND Signs and Symptoms including: Shock (hypoperfusion) Respiratory distress Wheezing, stridor, cough, hoarseness Chest / throat tightness Severe Allergic Reaction

  13. Severe Allergic Reaction • Itching, skin flushing • Urticaria (hives) (look at the torso!) and /or swelling (Especially the face and the extremities)

  14. Severe Allergic Reaction • Increased Pulse • Decreased Blood Pressure • Nausea & Vomiting • Altered Mental Status • Sense of impending doomsure with history of anaphylaxis

  15. An exaggerated immune response to an allergen Sudden, rapid onset Systemic involvement Severe allergic reaction Anaphylaxis

  16. Epinephrine • Generic Name • Epinephrine • Trade Name • EpiPen • EpiPen Jr. • Adrenalin

  17. EpinephrineActions • Dilates bronchioles • Constricts blood vessels • Increases heart rate • Increases cardiac output

  18. EpinephrineIndications • Signs and symptoms of severe allergic reaction • Compliance with the NH Patient Care Protocols

  19. EpinephrineContraindications None when dealing with anaphylaxis! BUT MUST FOLLOW NH PATIENT CARE PROTOCOLS!

  20. EpinephrineDosage • Adult • 1 adult Epi-pen auto-injector (0.3 mg) • Child • Child: greater than 10 kg and fit on a pediatric length based resuscitation tape (Broselow tape). • Epi-pen Jr. auto-injector (0.15 mg)

  21. EpinephrineRoute • Deep Intramuscular Injection • Lateral thigh, midway between waist and knee

  22. Increased pulse rate Pallor Dizziness Chest Pain Headache Nausea Vomiting Excitability / nervousness Anxiety Syncope EpinephrineSide Effects

  23. Epi auto-injector Administration • Remove safety cap from auto-injector • Hold auto-injector from center (DoNot place thumb over either end!) • Place against patient’s thigh • Lateral portion, midway between waist and knee

  24. Epi auto-injector Administration • Push until auto-injector activates • Hold until medication injected (10 seconds). • Record Time • Record Response to Medication • Dispose of auto-injector in biohazard “sharps” container.

  25. Emergency Medical Care Allergic Reaction/Anaphylaxis Patient Care Protocol January 2005

  26. Patient Assessment • Routine Patient Care • Scene Size-up • Initial Assessment (watch the airway!)

  27. Focused History • Determine SAMPLE Hx and Hx of Present Illness (HPI) : • Hx of allergies • What was patient exposed to now & then? • How was patient exposed? Now? Past? • Past & Current Signs and Symptoms? • Time of onset? • Progression? • Treatments already performed?

  28. Reassess ABCs Breath Sounds Baseline Vital Signs O2 Saturation Assess respiratory system Assess cardiovascular system Focused Physical Assessment  Assess for Signs & Symptoms of Anaphylaxis

  29. ANAPHYLAXIS • Summer of 2002, the NH Medical Control Board (MCB) and Seacoast Food and Allergy Group worked on the development of a protocol to allow EMT-Basic to administer Epipens and Epipen Jr.s supplied on EMS Units. • Adopted by MCB for 2003 Local Option Protocols • Standing Orders adopted by MCB 2005

  30. NH Patient Care AnaphylaxisProtocol • Call ALS • Administer oxygen • Assess respiratory status • Assess cardiac status • Vital signs

  31. NH Patient Care AnaphylaxisProtocol(cont.) • Caution needed when administering epinephrine to patients with history of CAD, HTN, etc. • If patient has signs / symptoms of an allergic reaction (hives, itch, anxiety) but is otherwise hemodynamically stable, contact medical control for further direction.

  32. NH Patient Care AnaphylaxisProtocol(cont.) • If trained to do so, administer Epi-Pen 0.3 mg or Epi-Pen Jr 0.15 mg IM for patient with signs / symptoms of anaphylaxis. • Do not delay transport, except for epinephrine administration. • Consider ALS intercept

  33. Ongoing assessment • Monitor A-B-Cs • Reassess vital signs • Oxygen! • Watch for changes in patient condition OXYGENATE OXYGENATE OXYGENATE

  34. If the patient deteriorates... Oxygenate Contact Medical Control for order for second dose Prepare for resuscitation Oxygenate Treat for shock Ongoing Assessment OXYGENATE OXYGENATE OXYGENATE Did we mention Oxygenate?

  35. Ongoing Assessment • Contacted Medical Control to administer a second auto-injector. • Be prepared to perform CPR if patient deteriorates.

  36. Communication • What? • Assessment Finding • Treatments • Result of Treatment • Who? • Other EMS providers • Receiving Facility personnel

  37. Documentation • What? • Assessment Finding • Treatments • Result of Treatment • Where? • PCR • Performance Improvement / Quality Improvement

  38. Goals Review! • Overview of General Pharmacology • Review the signs & symptoms & types of allergic reactions • Review of emergency care of a patient experiencing an anaphylactic reaction • Develop a basic knowledge of epinephrine & it’s administration • Identify situations when epinephrine may be indicated • Understand NH Patient Care Protocol - Anaphylaxis
