“Death I understand very well, it is suffering that I cannot understand.” -- Isaac C. Singer
“No patient should ever wish for death because of a physician’s reluctance to use adequate amounts of effective opioids.” -- Jerome H. Jaffe (Goodman and Gilman, 1990)
General Principles • Children feel pain. • Most pain in children’s diseases comes from medical diagnostic and therapeutic procedures. • Pain in CA pts can be a result of disease • Common at time of diagnosis, relapse, and at terminal phase
General Principles • As non-invasive as possible • As few doses/day with as little pain or disruption as possible. • PO preferred; RTC when available. • Chronically ill may have central lines. • Neurologically impaired may have gastrostomy tubes. • Subcutaneous route available for most palliative meds.
General Principles • Common not to have research-based, pediatric-specific indications for medications. • Children w/malignancies or HIV often have low platelet and WBC counts making rectal administration less acceptable.
General Principles • Children may have increased sensitivity to extrapyramidal side effects. • Children may have paradoxical reactions to benzodiazepines. • High-pitched crying and agitation • Children may have paradoxical reactions to barbituates. • Hyperactive
Annual mortality from life limiting illnesses • 1 per 10 000 children aged 1-17 years • Prevalence of life limiting illnesses • 10 per 10 000 children aged 0-19 years • In a health district of 250 000 people, with a child population of about 50 000, in one year • 5 children are likely to die from a life limiting illness—Cancer (2), heart disease (1), other (2) • 50 children are likely to have a life limiting illness, about half of whom will need palliative care at any time Numbers of children with life limiting illness BMJ 1998;316:49-52
Diseases for which curative treatment may be feasible but may fail Diseases in which premature death is anticipated but intensive treatment may prolong good quality life Cancer Cystic Fibrosis, HIV infection, AIDS Groups of life limiting diseases in children GROUPEXAMPLE BMJ 1998;316:49-52
Progressive diseases for which treatment is exclusively palliative and may extend over many years Conditions with severe neurological disability that, although not progressive, lead to vulnerability and complications likely to cause premature death Batten disease, Mucopolysaccharidoses Severe cerebral palsy Groups of life limiting diseases in children GROUPEXAMPLE BMJ 1998;316:49-52

Opioids • No maximum dose • No increased predisposition to respiratory depression (>3-6 mo) • Neuropathic and CNS-related pain will generally require adjuvants
Opioids • In pain crisis, load with incremental increases every 10-15 minutes to achieve 50% reduction in pain (arbitrary) • Start infusion if necessary to maintain analgesia • Important to have availability of rescue doses, ~ 5-10% of total daily dose q hour • If > 6 rescues/24 hours, increase base rate

Adjuvants • Antidepressants • Neuropathic pain • Amitryptyline 0.5-2 mg/kg qhs • Psychostimulants • Potentiates opioid analgesia • Counteracts opioid-induced sedation • Improves cognitive dysfunction
Adjuvants • Psychostimulants • Methylphenidate • initiate at 2.5 mg bid and titrate to effect • Dextroamphetamine • 2.5 mg qd (3-6 y/o) • 5 mg qd/bid

Adjuvants • Corticosteroids – dexamethasone is preferred agent • High potency • Longer duration of action • Minimal mineralcorticoid effect
Adjuvants • Anticonvulsants • Neuropathic pain • Carbamazepine, phenytoin, and valproate problematic (effect on hematologic profile) • Gabapentin well tolerated; benign efficacy-to-toxicity ratio
Alternative analgesic • Sucrose • 1 packet sugar in 10 cc water (29-30% sol’n) • Sweet Ease (24% sol’n) • 10 cc per bottle; swab oral mucosa; pacifier • Studied primarily in infants • Procedural pain • Relationship with holding and eye contact
