Dr. Korones Meets With Nestor's Mother

Dr. Korones makes a home visit to meet with Nestor's mother to go over the pain Nestor currently faces.

Summary of Findings From the History of Present Illness

  • Pain with movement and at rest
  • Grimacing
  • Heart and respiratory rate changes
  • Crying
  • Stiffness

Establishing a Baseline

Dr. Korones needs to establish what the patient is like at baseline, without apparent pain. This will provide useful information in determining the success of treatment.

Question 1

Based on the history and physical exam, select the likely causes of these episodes.

Correct. Determining the etiology of pain in the non-verbal child with severe developmental delay is a challenge. All of these choices are frequent and possible causes. Because these children are not mobile, they spend a lot of time in fixed positions (e.g., in a stroller or wheelchair), and develop gradual dislocation of the hips and experience pain, particularly with movement at the hips.
Correct. Determining the etiology of pain in the non-verbal child with severe developmental delay is a challenge. All of these choices are frequent and possible causes. The combination of growth, inability to sit or stand, and increased or decreased tone result in scoliosis, pain, and respiratory compromise.
Correct. Determining the etiology of pain in the non-verbal child with severe developmental delay is a challenge. All of these are frequent and possible causes. Formula intolerance, GI dysmotility and constipation are a common cause of pain.
Correct. Determining the etiology of pain in the non-verbal child with severe developmental delay is a challenge. All of these are frequent and possible causes. “Neuro-irritability” is a sustained activated state associated with crying, inconsolability. It is thought to be related to autonomic dysregulation and can mimic pain or be considered a cause of pain.
Correct. Determining the etiology of pain in the non-verbal child with severe developmental delay is a challenge. All of these are frequent and possible causes. Seizures are common and can mimic pain.

Question 2

Based on the differential diagnosis, what imaging studies (if any) would you order?

Incorrect. A head MRI is unlikely to reveal any abnormality that might be the cause of Nestor’s pain. In addition it is an expensive test for which anaesthesia would be required.
Correct. Plain films of the spine would be indicated to assess for scoliosis. Nestor could be experiencing scoliosis, a common finding in developmentally disabled children who are unable to sit or stand on their own. However, the presence of scoliosis is not always associated with pain (often it is not). Plain films of the hips could be helpful in diagnosing dislocation of the hip, a relatively common finding in developmentally disabled children who are not mobile.
Incorrect. This might be indicated if significant pathology was noted on the plain film of the spine, and an orthopedist felt that the additional information might help guide management.
Incorrect. An upper GI might be worth exploring if Nestor’s pain appeared to be abdominal in origin or was associated with feeding problems or vomiting.
Correct. Plain films of the spine would be indicated to assess for scoliosis. Nestor could be experiencing scoliosis, a common finding in developmentally disabled children who are unable to sit or stand on their own. However, the presence of scoliosis is not always associated with pain (often it is not). Plain films of the hips could be helpful in diagnosing dislocation of the hip, a relatively common finding in developmentally disabled children who are not mobile.

Imaging Ordered

Dr. Korones elects to order hip films on Nestor.

Nestor's Hip Films

The plain film of the hip reveals a left hip dislocation. Note the erosion of the left femoral head and the lack of interface between the femoral head and the acetabulum (see arrow). Compare the left and right hips.

Test Your Knowledge

What recommendation(s) for pain management will you make at this time?

Incorrect. Ibuprofen around the clock is indicated, but one should anticipate that a referral to an orthopedist will likely be needed as well.
Incorrect. Acetaminophen is unlikely to help since it has not been helpful in the past.
Incorrect. Morphine may ultimately be required, given the severity of the pain, but it is reasonable to start with ibuprofen.
Incorrect. Referral to an orthopedist is indicated, but Nestor should also be started on some anti-pain medication since it takes time to arrange such referrals.
Correct. Ibuprofen is a safe and effective non-steroidal anti-inflammatory drug that is particularly effective in relieving bony pain. Since Nestor has pain with movement of his legs and you suspect a dislocated hip, his pain is likely to be bony in origin. Regularly scheduled ibuprofen therefore may help relieve his pain. However, given the nature of his problem, ibuprofen alone is unlikely to control the pain. He will likely require the input of a pediatric orthopedic surgeon (especially if there is a dislocation) to determine whether a surgical intervention or less invasive intervention (like a brace) is necessary.

Explanation of Treatment

Dr. Korones explains his choice of treatment to Nestor's mother.

Non-Opioid Medications Used In Pediatric Pain Management

The following table describes the major non-opioid medications used in pain management for the pediatric population. Note clinical considerations  and contraindications for each agent.  

Non-Opioid Pain Medications Used in Pediatric Pain Management
Drug Properties Usual Pediatric Dose Clinical Comments
Acetaminophen Inhibits central prostaglandin synthesis

PO: 10-15 mg/kg/dose every 4-6 hours; not to exceed 5 doses

Rectal: 20 mg/kg/dose every 6 hours

Caution with prescription 
and non-prescription combination products containing acetaminophen 

Avoid use in patients with 
liver disease

Ibuprofen Non-steroidal anti-
inflammatory (NSAID)
PO:  10 mg/kg/dose every 
6-8 hours

Caution in patients with renal 
insufficiency; increased risk of GI ulcers and bleeds 

Avoid in <6 months of age

Ketorolac Non-steroidal anti-
inflammatory (NSAID)
IV:  0.25 - 0.5 mg/kg/dose 
every 6-hours

Maximum duration of treatment

May have GI and hematological 
effects

Naproxen Non-steroidal anti-
inflammatory (NSAID)
PO:  5 – 6 mg/kg/dose every 
8 - 12-hours
May have GI and hematological 
effects

Factors Placing Pediatric Patients at Increased Risk of Adverse Reactions with Medications

  • Pharmacokinetic Differences 
  • Calculation of Individualized Doses 
    • Age
    • Weight (mg/kg)
    • Body Surface Area 
  • Lack of available dosage forms 
  • Lack of published information or FDA approval 
  • Lack of communication skills 
  • Limited Internal reserve to buffer errors
