chronic conditions
• Use of non-pharmacological methods to reduce pain and anxiety in
pediatric patients
• Reduce pain related to painful procedures
Pain in Pediatric

‘‘Control of pain and stress for children who enter into the
emergency medical system… is a vital component of
emergency care.’’

Océane is still suffering: Why?
• No pain measurement on arrival
• Underestimation of pain
• No evaluation of pain after analgesia
• Fear of analgesia from parent-patient-doctor
• Limited knowledge on treatment strategies and consequences of
undertreatment
• Lack of time
• Lack of human resources

Complex regional pain syndrome (CRPS)
Signs /symptoms
• Severe pain
• Allodynia and hyperalgesia
• Autonomic signs: edema, sweating, coolness, skin discoloration
• Motor signs: dystonia, tremors
• Trophic signs: changes in nail/hair growth
CRPS
• Pathophysiology not completely understood
• Clinical diagnosis, based on Budapest criteria for adults
• Several diagnoses and treatments (often including
immobilization) before the CRPS diagnosis
• Severe functional impairments quite common
CRPS in children
• Lower limbs more often that upper limbs
• More common in girls
• In general occurs in early teens (around 13 yo)
• Much better prognosis than in the adult population
Chronic pain syndromes in general
• More common in girls
• Sleep problems
• Mental health issues (depression, anxiety)
• School absenteeism
• Fatigue
• Familial issues (distress)
• Hypermobility
ici.radio-canada.ca
Tissue damage
Nociceptive pain
Nociceptive receptors more
easily activated
Central sensitization
Persistent pain even if
inflammation signs are
decreasing
Chronic pain syndromes
Initial discussion about diagnosis: Crucial!
• Similar explanations no matter what is the pain problem
• In general: Minimal investigations... but follow up is essential
• Acceptance of diagnosis by the family
• Active implication of the family in the treatment
• The pain becomes the disease in itself
• Patients are often told that the pain is in their head
Treatment of chronic pain syndromes
• Focus of treatment:
• learning how to restore functionality on a daily basis
• Combination of:
• physical therapy
• psychology
• pharmacology
Medications in Chronic pain
syndromes
• Opioids rarely used in the pediatric population
• Medications acting on brain neurotransmitters and calcium
channels
• gabapentin, pregabalin
• amitriptyline, nortriptyline (TCAs)
• Few studies regarding the efficacy of these medications in
chronic pain in the pediatric population
Gabapentin
• Binds to voltage-gated calcium channels
• Commonly used in pediatrics for neuropathic pain
• Low incidence of drug-drug interactions
• Side-effects: somnolence, dizziness, unsteadiness
• When titrated slowly, well tolerated even in young children
• Dosage:
• start at 3-5 mg/kg at night, then BID and TID
• up to 20-30 mg/kg/day
• Max 3600 mg per day
TCAs (amitriptyline and
nortriptyline)
• Blockade of serotonin and noradrenaline reuptake & interaction
with sodium and calcium ion channels
• No RCTs in children for neuropathic pain but widely used
• Advantage: once daily, somnolence (if sleeping problems)
• Side-effects: dry mouth, sedation, blurred vision, urinary rentention,
constipation tachycardia, QTc prolongation
• Dosage
• Start at 10 mg q hs
• increase slowly depending on side-effects and analgesia
Follow up
• Physical therapy as soon as possible
• focus on restoring activities of daily living (such as walking...)
• desensitization exercises
• Psychology follow up
• Cognitive Behavioral Therapy
• relaxation techniques
• hypnosis, etc...
• Pain clinic
• Physiatrist
62
Conclusion
• Objective evaluation of pain
• Pharmacological and non-pharmacological analgesia
• For procedures
• For acute painful conditions
• For chronic painful conditions
• Think about it and take the TIME!

    Chronic pain syndromesin general • More common in girls • Sleep problems • Mental health issues (depression, anxiety) • School absenteeism • Fatigue • Familial issues (distress) • Hypermobility ici.radio-canada.ca

    Tissue damage Nociceptive pain Nociceptivereceptors more easily activated Central sensitization Persistent pain even if inflammation signs are decreasing

    Chronic pain syndromes Initialdiscussion about diagnosis: Crucial! • Similar explanations no matter what is the pain problem • In general: Minimal investigations... but follow up is essential • Acceptance of diagnosis by the family • Active implication of the family in the treatment • The pain becomes the disease in itself • Patients are often told that the pain is in their head
  • 57.
    Treatment of chronicpain syndromes • Focus of treatment: • learning how to restore functionality on a daily basis • Combination of: • physical therapy • psychology • pharmacology
  • 58.
    Medications in Chronicpain syndromes • Opioids rarely used in the pediatric population • Medications acting on brain neurotransmitters and calcium channels • gabapentin, pregabalin • amitriptyline, nortriptyline (TCAs) • Few studies regarding the efficacy of these medications in chronic pain in the pediatric population
  • 59.
    Gabapentin • Binds tovoltage-gated calcium channels • Commonly used in pediatrics for neuropathic pain • Low incidence of drug-drug interactions • Side-effects: somnolence, dizziness, unsteadiness • When titrated slowly, well tolerated even in young children • Dosage: • start at 3-5 mg/kg at night, then BID and TID • up to 20-30 mg/kg/day • Max 3600 mg per day
  • 60.
    TCAs (amitriptyline and nortriptyline) •Blockade of serotonin and noradrenaline reuptake & interaction with sodium and calcium ion channels • No RCTs in children for neuropathic pain but widely used • Advantage: once daily, somnolence (if sleeping problems) • Side-effects: dry mouth, sedation, blurred vision, urinary rentention, constipation tachycardia, QTc prolongation • Dosage • Start at 10 mg q hs • increase slowly depending on side-effects and analgesia
  • 61.
    Follow up • Physicaltherapy as soon as possible • focus on restoring activities of daily living (such as walking...) • desensitization exercises • Psychology follow up • Cognitive Behavioral Therapy • relaxation techniques • hypnosis, etc... • Pain clinic • Physiatrist

    62 Conclusion • Objective evaluationof pain • Pharmacological and non-pharmacological analgesia • For procedures • For acute painful conditions • For chronic painful conditions • Think about it and take the TIME! gettyimages.ca/Cysale
