II. Evaluation: Pain Rating Scales

  1. FLACC Scale (Face, Legs, Activity, Cry, Consolability Scale)
    1. Indicated for preverbal children over age 2 months
  2. Wong-Baker FACES Pain Rating Scale
    1. Reliable pain rating scale for ages 4 to 12 years old
  3. Numeric Rating Scale (adult Pain Scale)
    1. Rate pain from 0 (no pain) to 10 (worst possible pain)
    2. May be appropriate for children over age 8 years old

III. Precautions

  1. Children's pain is frequently under-treated in the emergency department
    1. Conditions are just as painful for children as they are for adults
      1. Pain transmission pathways are fully developed by 22 to 24 weeks gestation
      2. However pain inhibitory pathways are no fully developed in infants
        1. Infants may experience pain more than in older children
    2. Do not lie and do not make promises you cannot keep
    3. Empower children to pause the procedure when something is too painful
      1. Increases the pain threshold when they have the power to say stop
    4. Repeated and persistent untreated pain in children can have short and long lasting effects
      1. Short-term: Greater suffering, decreased function, increased and prolonged encounters
      2. Long-term: Procedure avoidance, heightened sensitivity and fear, lower pain thresholds, hyperalgesia
  2. Avoid Tramadol in children (risk of significant respiratory depression)
    1. Seen with Ultrarapid CYP2D6 metabolizers
    2. Avoid Tramadol use in children
    3. http://www.fda.gov/Safety/MedWatch/SafetyInformation/SafetyAlertsforHumanMedicalProducts/ucm463499.htm
  3. Avoid Codeine in children
    1. Same concern with CYP2D6 ultrarapid metabolizers
  4. Exercise caution with Hydrocodone and Oxycodone
    1. Also metabolized by CYP2D6, but issues with Codeine and Tramadol not reported with these other agents

VIII. Preparations: Intranasal Analgesics and Sedatives

  1. See Intranasal Drug Delivery Route
  2. Approach
    1. Maximal amount that may be absorbed intranasally is 0.3 ml
    2. Typical drug delivery is via a Mucosal Atomization Device (MAD Atomizer)
      1. Device has 0.1 ml dead space (draw up extra 0.1 ml medication)
      2. Alternatives when atomizer is unavailable
        1. Slow drip into the nose via syringe
        2. Syringe with angiocatheter plastic tip with slow drips into the nose
    3. Technique
      1. Blow nose before administration (Rhinorrhea and mucous may interfere with absorption)
      2. Direct the MAD Atomizer toward the occiput or ipsilateral eye (not up)
  3. Intranasal Fentanyl
    1. Dose: 1.5 to 2 mcg/kg intranasal up to 100 mcg/dose (1/2 in each nostril) via MAD Atomizer
  4. Intranasal Midazolam or Versed (for sedation for anxiolysis)
    1. Opioids are generally used instead (often with better effect)
    2. Dose: 0.3 to 0.5 mg/kg up to 10 mg/dose intranasal (1/2 in each nostril) using 5 mg/ml solution
    3. Onset in 3 to 5 minutes, peak effect in 10 minutes and duration 20 minutes
  5. Intranasal Ketamine (not in mainstream use yet as of 2022)
    1. Analgesia
      1. Ketamine 1 to 1.5 mg.kg (1/2 in each nostril)
    2. Procedural Sedation
      1. Use Ketamine 100 mg/ml if available (maximal nasal dose volume 0.5 ml)
      2. Dose: 2 to 4 mg/kg intranasally
      3. Onset of action: 10 min
      4. Duration: 15-20 min (up to 60 min)
      5. Observe for 60 min after procedure
    3. Efficacy
      1. Anecdotally not as affective as other routes of Ketamine, and Intranasal Fentanyl
      2. However prior dosing (1 mg/kg) was likely too low for Procedural Sedation
