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.
