The intrathecal infusion of drugs to provide analgesia for terminally ill children with refractory pain is a rarely utilized but very effective technique. A number of pharmacological agents, most commonly opioids and local anesthetics, have been administered intrathecally for this purpose. However, tachyphylaxis and neuraxial opioid-related side effects can limit their utility. The alpha-2 agonist clonidine is commonly used to augment local anesthetic techniques for postsurgical pain in children and for the management of refractory cancer pain in adults, but there is only a single report of the use of clonidine intrathecally in a terminally ill child. We present the case of the youngest reported child to have received intrathecal analgesia for terminal care: a 3-year-old boy with advanced pelvic rhabdomyosarcoma, whose refractory pain was managed effectively with an intrathecal infusion of bupivacaine and preservative-free clonidine.
鞘内注射药物为患有顽固性疼痛的晚期儿童提供镇痛是一种很少使用但非常有效的技术。为此,已鞘内注射多种药物,最常用的是阿片类药物和局部麻醉药。然而,快速耐受和与鞘内阿片类药物相关的副作用可能会限制它们的效用。α-2激动剂可乐定通常用于增强儿童术后疼痛的局部麻醉技术以及成人顽固性癌痛的管理,但仅有一份关于在晚期儿童中鞘内使用可乐定的报告。我们报告了已知接受鞘内镇痛进行临终关怀的最小儿童病例:一名3岁晚期盆腔横纹肌肉瘤男孩,其顽固性疼痛通过鞘内注射布比卡因和无防腐剂可乐定得到有效控制。
