Official title

Effects of Pre-operative Pregabalin and Ketamine to Prevent Development of Phantom Pain in Patients Undergoing Lower Extremity Amputation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Phantom limb pain (PLP) is as painful sensations located to the missing limb and classified as neuropathic pain. In the United States, an estimated 1.7 million patients have undergone limb amputation, and 60% to 80% of these patients develop PLP (1-2) and it is usually resistant to a wide variety of treatments (1-4). Three factors may contribute to the development of persistent, post-amputation PLP by inducing central sensitization at different times relative to surgery: pre-amputation pain, noxious intraoperative stimuli, and acute postoperative pain (5-7). Investigators hypothesis that pre-amputation period could be important in eliminating Phantom Limb Pain (PLP) in the patients in whom cortical reorganization is not yet established. The reduction of pre-operative pain and prevention of formation of pain memories may eliminate development of PLP by using dual networks treatment strategy. This Phase III, randomized, double-blind, placebo-controlled study is designed to evaluate the efficacy of pre-operative pregabalin (lyrica) and ketamine in eliminating phantom limb pain in patients undergoing lower limb amputation.
