Filter by:For more than 25 years, Regional Anesthesia has challenged anesthesiologists to determine whether it offers real benefits in terms of patient outcome from major surgery, compared with general anesthesia. Although it is clear that regional analgesia in association with general anesthesia substantially reduces postoperative pain, the benefits in terms of overall perioperative outcome are controversial. The aim of this study is to evaluate the effect on short and long-term postoperative outcomes of adding regional analgesia to general anaesthesia in thoridetomic patients.
The purpose of this study is to determine whether an integrated behavioral treatment approach can help overweight or obese individuals who also have chronic pain reduce their weight and manage their pain symptoms. The goal of this research is to develop better treatments for individuals with chronic pain and overweight or obesity. All participants in this study will receive treatment for weight management and/or pain symptoms. Participants will be assigned at random (like we picked it blindly out of a hat) to receive either: (1) Standard behavioral treatment for weight loss; or (2) Standard behavioral treatment for pain management; or (3) Integrated behavioral treatment for weight loss and pain.
The aim of the study is to evaluate efficacy and safety of long term (14 days) wound infusion with levobupivacaine in patients with breast cancer undergoing mastectomy with immediate breast reconstruction: this is a double blind, randomized, parallel group study. The study moves from the concept that nociceptive stimulus last further than 48 hours after surgical intervention: long term analgesia is necessary to provide a real benefit to the patient and provide central sensitization. Intralesional catheter is placed at the end of surgery. In the first 24 postoperative hours we provide continuous wound infusion with levobupivacaine 0,25% 5ml/h with morphine Patient Controlled Analgesia (PCA) when NRS >4. From the second postoperative day morphine PCA is removed and patients are randomized to receive levobupivacaine 0,25% or saline, released with 5 ml boluses and lock-out of 2 hours, with rescue analgesia with tramadol 37,5 mg + acetaminophen 325 mg oral fix combination (Patrol). Intralesional catheter is taken off 14 days after surgical intervention or after 36 hours of non-use. Pain evaluation (NRS at rest and movement) and oral rescue doses consumption are performed; pain physicians also care about any catheter-related or drug-related side effect, registering number of total boluses. Patients are provided with a home diary for pain scores to be filled and brought back when surgical visit is performed. A phone interview at 1 and 3 month is performed to investigate pain chronicization. Surgical evaluation is provided, also to establish any catheter-related infective or healing complication. Physiatric evaluation before the intervention and 1 and 3 months is provided to ensure rehabilitation process. A validated questionnaire (short form 36/ SF-36) must be filled by all patients, to understand differences in return to a normal quality of life and to social activities between the two groups.
Pain is the way our brain interprets certain bodily sensations. It is very difficult to describe or to put into words as perception and tolerance of pain varies widely between individuals. It is known that age, gender and past experience and memory of past experience all contribute to patients' feelings of discomfort and tolerance of pain, but the reason why some patients actually do not experience any pain at all post surgery is still unknown. Because pain affects every person at some point in their lives, it is of utmost importance that we can find more effective analgesic methods, and provide analgesia tailored to an individual's need as well as discovering new methods which may be able to identify those individuals who are more prone to suffering serious, or chronic pain. It has been proposed that epigenetic modifications may play a role in sensitivity to analgesia and response to trauma, such as post surgery. The effects of epigenetic changes on key genes and the role this plays in analgesia sensitivity and pain perception is deserving of further research. Epigenetics is a growing field of study in which there are genetic modifications that do not involve changes to base sequences in a gene, but that result nonetheless in changes to gene expression. It has long been known that changes in gene expression play an important role in the establishment of pain states. But it is not known whether a priming injury can induce lasting epigenetic marks which would result in an increase in both postoperative acute pain and the risk for chronic pain. Only by fully understanding these epigenetic mechanisms will we be able to offer better drugs for the treatment of pain, and to identify those at high risk of postoperative pain and postsurgical chronic pain. The purpose of this study is to determine whether severity of pain following surgical procedures, such as third molar surgery is related to baseline methylation status of the promoter region of IL-6 and TNF-α and changes in methylation status post surgery.
This study will determine the efficacy of High Intensity Laser Therapy (HILT) for the treatment of elbow epicondylosis
The purpose of this study is to investigate if rTMS may have a positive impact on pain thresholds and cortical excitability in subjects with chronic musculoskeletal diseases of complex cranio-cervical-mandibular with myofascial component.
The purpose of this study is to evaluate effectiveness and cerebral neuronal ability to adaptation in patients with fibromyalgia who receive pregabalin and transcranial direct current stimulation.
Sportsman's hernia causes chronic groin pain in physically active adults. Open hernia repair without mesh or laparoscopic technique with mesh have been advocated in the treatment of sportsman's hernia. The aim of this randomized study is to compare the effectiveness of open technique to laparoscopic technique for the treatment of Sportsman´s hernia. The hypothesis is that laparoscopic technique is less painfull than open surgery for repair of sportsman's hernia.
The purpose of this study is to investigate whether a psycho-therapeutic approach, group Cognitive Behavioral Therapy (CBT) plus a relapse prevention program, Therapeutic Interactive Voice Response (TIVR), modifies the dysfunctional sensory, emotional, and cognitive neural circuitry associated with chronic pain.
The purpose of this study is to determine the degree to which spinal cord stimulation added to comprehensive medical management can provide increased relief of chronic pain in patients with injuries sustained while on active military duty, measured by patient assessments of pain.
