Brief Summary

Severe pre-amputation pain is associated with phantom pain development, and phantom pain models assign major importance to central and peripheral nervous system changes related to pre-amputation pain. Several interventions have been evaluated for phantom pain prevention, including continuous brachial plexus blockade5, intravenous6 or epidural ketamine administration, postoperative perineural ketamine/clonidine infusion8 and oral gabapentin9, but their true effect remains unclear.

Outcome Measures

Primary Outcomes (1)

  • VAS and McGill PRI(R)2 scores for phantom and stump pain are recorded 48 and 24 hours before, and 4 and 10 days, 1 and 6 months after amputation. Phantom and stump pain intensity are the endpoints of the study.
