Filter by: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.
Analgesia following leg amputation is based on morphine administration. For elderly patients of ASA physical status 2 or 3, morphine sparing is possible when perinervous block techniques are used. Phantom limb pain complicates leg amputation in 50 to 80% of cases. Prevention of these pains has been studied in various clinical trials but the interest of perinervous block technique remains to be evaluated. The purpose of the study is to evaluate the benefit of perioperative locoregional analgesia by ropivacaine via a popliteal sciatic catheter on intravenous morphine consumption during the 72 first postoperative hours following leg (below knee) amputation The study will be randomized, double blinded, controlled clinical trial and 84 patients undergoing leg amputation (below knee) will be included Patients will be divided into 2 groups: one group of patients who will benefit perioperative locoregional analgesia by ropivacaine via a popliteal sciatic catheter and morphine for analgesia and the other one who will benefit placebo through the catheter and morphine. The investigators will evaluate the efficacy of the continuous popliteal sciatic nerve block in postoperative analgesia after leg amputation and prove the efficacy of a perioperative analgesia by continuous popliteal sciatic nerve block to prevent phantom limb pain after leg amputation in patients of ASA physical status 2 or 3.
This is a study to assess the possible benefit of duloxetine in the treatment of chronic phantom limb pain.
The purpose of this study is to identify the best treatment sequence and combination of acupuncture points for the treatment of phantom limb or residual limb pain in the traumatic/surgical amputee.
The researchers propose to conduct a pilot study on the efficacy of mirror-box and mental visualization treatments on phantom limb pain. The trial will last for 4 months and during the first month, data will be gathered daily on the number of episodes of phantom limb pain, the average length of episodes, average intensity of pain, and worst intensity of pain. In addition, the rapidity of pain relief, the length of therapy needed to sustain long-lasting pain relief, and whether use of these two treatment methods during rehabilitation can provide sustained and/or permanent pain relief will be determined. Cognitive testing will also be performed to determine the effect of limb amputation on cognition and mood with results being compared to an on-going study of similar effects in patients with chronic (> 3 months) limb amputation. The inclusion of subjects with phantom limb pain in upper extremity amputations has recently been approved.
