Cancer pain management in children.

Unrelieved pain may have a major impact on the care of children with cancer. The type and severity of pain experienced by children with cancer varies from acute, procedure-related pain to progressive chronic pain associated with the progression of the disease or sequelae of treatment. Drugs are the mainstay of treatment. Regular pain assessments combined with appropriate analgesic administration at regular dosing intervals, adjunctive drug therapy for control of adverse effects and associated symptoms, and nonpharmacological interventions are recommended. Although standard dosing of opioids adequately treats most cancer pain in children, more complex treatment is required by a significant group. Strategies to improve analgesia include the use of epidural or intrathecal infusions of a combination of opioids and other adjuvants, or other regional anaesthesia techniques. Procedure- and treatment-related pain is an even greater problem than cancer pain. Recommendations have been published with regard to the monitoring and personnel required when children are sedated which aim to set the standard of care and minimize both physical discomfort or pain and negative psychological responses, by providing analgesia; and to maximize the potential for amnesia; and to control behaviour.
