Hypoglycemia

This policy applies to: Patients with blood sugar < 60 mg/dl

Exclusion Criteria: None

Recognize

Recognize
  • Altered mental status
  • Anxiety
  • Slurred speech
  • Sweating
  • Pale skin
  • Tremors
  • Seizures
  • Medic alert bracelet / jewelry
  • Altered mental status
  • Anxiety
  • Slurred speech
  • Sweating
  • Pale skin
  • Tremors
  • Seizures
  • Medic alert bracelet / jewelry

Evaluate

  • Primary survey with airway management
  • Obtain blood glucose measurement

Administer Treatment

  • Remove allergy trigger if known and present
  • Prioritize interventions based on clinical presentation and severity of reaction
  • Supplemental oxygen PRN for goal SpO2
  • Attentive and prompt airway assessment and management
     Airway Management if indicated per Airway Management PCG (P1)
  • If patient has suspected or known exposure and exhibits signs of any: respiratory distress, airway
    restriction, altered mental status or shock, treat accordingly
      • Epinephrine Auto-Injector 0.3 mg IM if available
      • Vascular access per Vascular Access PCG (P33)
      • Consider crystalloid fluid bolus 500 mL IV/IO to support hemodynamics, repeat PRN
      • Diphenhydramine (Benadryl) 50 mg IM/IV/IO
      • Epinephrine (1mg/1mL) 0.3 mg IM or Epinephrine (1mg/10mL) 0.1 mg IV/IO q 3 min PRN for
        MORE SEVERE REACTION
          • Consider Epinephrine infusion 0.01 mcg/kg/min IV/IO, titrate to max 0.1 mcg/kg/min
            as an alternative to repeat IM or IV/IO doses
          • Monitor ECG rhythm closely, Epinephrine may potentiate arrhythmias, especially in
            patients over the age of 40
      • Methylprednisolone (Solu-Medrol) 125 mg IV/IO
      • Albuterol (2.5 mg/3 mL) nebulized for wheezing or shortness of breath

Consider Differentials

  • Urticaria (rash only)
  • Anaphylaxis (severe systemic effect)
  • Shock (severe vascular effect)
  • Angioedema (drug induced or infection)
  • Aspiration / airway obstruction
  • Vasovagal event
  • Asthma or COPD
  • Infection (ex: retropharyngeal abscess, bacterial tracheitis, croup, epiglottitis, strep)
  • Pulmonary edema or CHF
  • Metabolic disorders

Transport Considerations

  • During transport, maintain astute airway, breathing, circulation and mental status assessment with
    prompt intervention as needed. Stability can quickly change to instability in these patients.
  • Consider early airway management, reference Airway Management PCG (P1)

Information

  • Typically, the shorter the interval from exposure to symptoms, the more severe the reaction
  • Hemodynamic instability may recur up to 24 hours after initial stabilization

Other Populations

  •  Neonatal/ Pediatric drug dosing:
      • Pediatric Epinephrine Auto-Injector JR dose is 0.15 mg for patients 15-30 Kg
      • Diphenhydramine (Benadryl) 1 mg/Kg IM/IV/IO over 5 min max dose 50 mg
      • Epinephrine (1mg/1mL) 0.01 mg/Kg IM/IV/IO q3 min until stable or infusion started
          • Max 0.5 mg per dose (Intentionally larger than adult dosing)
          • Epinephrine infusion 0.01 mcg/Kg/min IV/IO, titrate to max 1 mcg/kg/min
      • Methylprednisolone (Solu-Medrol) 2 mg/Kg IV/IO max dose 125mg
      • Albuterol for 15 Kg or more, use adult dose
      • Albuterol for less than 15 Kg (1.25mg/ 3ml) nebulized with O2 at 6 lpm
