Important differences become evident in a comparison of cancer pain between children and adults. Management of pain in children is commonly multidisciplinary, is less dependent on invasive measures and relies more on systemic therapy. Children are not little adults: their immaturity, developing cognition and dependence all influence their experience and interpretation of pain. Much progress has been made in altering practices such as under-prescribing and underdosing that have adversely affected adequate control of pain in children. The challenge for paediatric health care providers in the mid 1990s is not only to be informed of current practices in pain and symptom control in paediatric palliative care, but also to remember to establish those practices in day to day management. Even though pain and its effects in children are now better understood, it is often still not managed optimally. Good management of pain in children depends on accurate assessment. In the past 10 years, assessment of pain in children has advanced considerably. However, assessment of pain in the preverbal child is still inadequate and in need of attention. Sedation, tolerance and involuntary movements may occur as side effects of opioids in children and may cause significant problems in management of the dying child. Psychostimulants can diminish sedation to some extent, but there is little information as yet on the value of these drugs in children. Tolerance to opioids may develop quickly, leading to poor control of pain and distress for the child. Strategies to improve management of tolerance include use of regional anaesthetic techniques such as the epidural/intrathecal route for opioid administration. Involuntary movements induced by opioids are uncommon but have the potential to cause significant distress. The mechanisms underlying these side effects of opioids need to be established. Strategies are needed for the effective treatment and prevention of these side effects. Neuropathic pain can be severe, distressing and difficult to treat. Experience of its treatment in terminally ill children is limited. Effective use of tricyclic antidepressants and systemically administered local anaesthetics is still to be determined. Regional anaesthetic techniques may be of great benefit when neuropathic pain cannot be controlled with systemic therapy. Procedural pain is more common than pain related to disease in the management of paediatric cancer. Further research is needed to identify the best approach to its management. We have found nitrous oxide to be of great benefit in management of procedural pain in children. Non-pharmacological methods of treatment of pain in children, such as transcutaneous electrical nerve stimulation or acupuncture, may also be useful and should receive continuing evaluation. There are significant and current issues in paediatric palliative care besides management of pain. There are difficulties in the provision of home nursing care for children with cancer in the terminal phase of their illness, including lack of community nursing services at night and on weekends and lack of adequate home help for parents. Attitudes of staff involved in the care of the child and family and their commitment to working as a multidisciplinary team strongly influence the quality and success of care given. Pain control and palliative medicine are evaluable by measures of quality assurance or outcome, and adoption of such evaluations should improve standards of care. Euthanasia in children is even more difficult as an ethical dilemma than in adults. Optimum symptom control with current techniques should almost always obviate its consideration. We are opposed to euthanasia. Psychosocial and cultural issues all influence the family's experience of palliative care. Further research is necessary in all of these areas.(ABSTRACT TRUNCATED)
儿童与成人癌症疼痛的比较中,重要差异显而易见。儿童疼痛管理通常是多学科的,较少依赖侵入性措施,更多依赖全身治疗。儿童不是小大人:他们的不成熟、认知发展和依赖性都会影响他们对疼痛的体验和理解。在改变诸如处方不足和剂量不足等对儿童疼痛充分控制产生不利影响的做法方面已取得很大进展。20世纪90年代中期,儿科医疗保健提供者面临的挑战不仅是要了解儿科姑息治疗中疼痛和症状控制的当前做法,还要记得在日常管理中确立这些做法。尽管现在对儿童疼痛及其影响有了更好的理解,但疼痛管理往往仍未达到最佳状态。儿童疼痛的良好管理取决于准确评估。在过去10年里,儿童疼痛评估有了很大进展。然而,对不会说话儿童的疼痛评估仍然不足,需要关注。镇静、耐受性和不自主运动可能作为阿片类药物在儿童中的副作用出现,并可能在临终儿童的管理中引起重大问题。精神兴奋剂在一定程度上可以减轻镇静,但关于这些药物在儿童中的价值的信息还很少。对阿片类药物的耐受性可能迅速发展,导致儿童疼痛和痛苦控制不佳。改善耐受性管理的策略包括使用区域麻醉技术,如通过硬膜外/鞘内途径给予阿片类药物。阿片类药物引起的不自主运动并不常见,但有可能导致严重痛苦。这些阿片类药物副作用的潜在机制需要确定。需要有策略来有效治疗和预防这些副作用。神经性疼痛可能很严重、令人痛苦且难以治疗。在晚期患病儿童中其治疗经验有限。三环类抗抑郁药和全身给予局部麻醉药的有效使用仍有待确定。当神经性疼痛无法通过全身治疗控制时,区域麻醉技术可能非常有益。在儿科癌症管理中,程序性疼痛比与疾病相关的疼痛更常见。需要进一步研究以确定其最佳管理方法。我们发现氧化亚氮在儿童程序性疼痛管理中非常有益。儿童疼痛的非药物治疗方法,如经皮电刺激神经疗法或针灸,也可能有用,应持续评估。除了疼痛管理外,儿科姑息治疗中还有重大的当前问题。为处于疾病终末期的癌症儿童提供家庭护理存在困难,包括夜间和周末缺乏社区护理服务以及父母缺乏足够的家庭帮助。参与儿童和家庭护理的工作人员的态度及其作为多学科团队工作的承诺强烈影响所提供护理的质量和成功。疼痛控制和姑息医学可以通过质量保证或结果指标进行评估,采用此类评估应提高护理标准。儿童安乐死作为一个伦理困境比成人更难。用现有技术实现最佳症状控制几乎总能排除对此的考虑。我们反对安乐死。心理社会和文化问题都会影响家庭对姑息治疗的体验。所有这些领域都需要进一步研究。(摘要截选)
