Children often do not express pain in terms that are easily understood by adults. Distraction by parents or other factors may address the emotional component of pediatric pain, leading caregivers to assume that no physical pain exists. This review of acute pain management in children examines traditional practices as well as recent developments in acute pain management in infants and children.

Recent research advances indicate that specialized neural pathways are involved in the encoding of pain sensations and that these pathways are sensitive to changes in stimulus features, such as intensity, quality, duration, and location. It has also been established that there are three major families of opioid peptides in the brain: the enkephalins, the dynorphins, and the endorphins. In addition to these opioid peptides, other neurochemicals such as serotonin and norepinephrine play a role in the modulation of signals related to tissue damage. ⋯ Opioid drugs are administered into the membranes surrounding the spinal cord to provide long-lasting pain relief. Peripherally acting opioid drugs may represent a new functional class of analgesics devoid of the undesirable side effects of centrally acting opioids. Tricyclic antidepressant drugs are used in the treatment of neuropathic pain, based on their effects on noradrenergic and serotoninergic pathways in the central nervous system.

Migraine headache variants consist of the complicated migraine headache subtypes such as basilar artery migraine, migraine equivalents, and late-life migraine accompanients. Although these disorders occur infrequently, diagnosis may be more difficult. Generally, comprehensive diagnostic studies are required to rule out underlying pathogenic conditions that may present with similar symptom complexes. Standard migraine treatment is often useful in these disorders; however, migrainous variants deserve special therapeutic considerations.

Psychological factors are known to increase the severity and intensity of headaches. When they are shown to be present, an appropriate psychiatric diagnosis is the Diagnostic and Statistical Manual's (DSMIII-R) category of psychological factors affecting physical condition (code no. 316.0). ⋯ The factors overlap and intertwine in the average headache patient. Attention to these factors in a systematic way should enhance our understanding and treatment of the chronic headache patient.
