摘要

BACKGROUND: Pain and other sensations from an amputated or absent limb, called phantom pain and phantom sensations, are well-known phenomena.OBJECTIVE: The aim of this retrospective study was to evaluate the effects of anesthetic techniques on phantom pain, phantom sensations, and stump pain after lower limb amputation.METHODS: Ninety-two patients with American Society of Anesthesiologists physical status I to III were analyzed for 1 to 24 months after lower limb amputation in this retrospective study. Patients received general, spinal, or epidural anesthesia or peripheral nerve block for their amputations. Standardized questions were used to assess phantom limb pain, phantom sensation, and stump pain postoperatively. Pain intensity was assessed on a numeric rating scale (NRS) of 0 to 10. Patients' medical histories were determined from hospital records.RESULTS: Patients who received epidural anesthesia and peripheral nerve block perceived significantly less pain in the week after surgery compared with patients who received general anesthesia and spinal anesthesia (NRS [SD} values, 2.68 [1.0] and 2.70 [1.0], respectively). After approximately 14 to 17 months, there was no difference in phantom limb pain, phantom sensation, or stump pain among the anesthetic techniques for amputation.
