Multimodal analgesia may include pharmacological components such as regional anesthesia, opioid and nonopioid systemic analgesics, nonsteroidal anti-inflammatories, and a variety of adjuvant agents. Multimodal analgesia has been reported for a variety of surgical procedures but not yet for lower limb amputation in vasculopathic patients. Perioperative pain management in these patients presents a particular challenge considering the multiple sources and pathways for acute and chronic pain that are involved, such as chronic ischemic limb pain, postoperative residual limb pain, coexisting musculoskeletal pain, phantom limb sensations, and chronic phantom limb pain. These pain mechanisms are explored and a proposed protocol for multimodal analgesia is outlined taking into account the common patient comorbidities found in this patient population.
多模式镇痛可能包括药理学成分,如区域麻醉、阿片类和非阿片类全身镇痛药、非甾体抗炎药以及多种辅助药物。多模式镇痛已被报道用于多种外科手术,但尚未用于血管病变患者的下肢截肢手术。考虑到这些患者急性和慢性疼痛涉及的多种来源和途径,如慢性肢体缺血性疼痛、术后残肢疼痛、并存的肌肉骨骼疼痛、幻肢感觉和慢性幻肢疼痛,围手术期疼痛管理面临特殊挑战。本文探讨了这些疼痛机制,并根据该患者群体中常见的患者合并症概述了一种多模式镇痛方案。
