Filter by:Osteoarthritis (OA) is disease in which the joint breaks down, causing pain. The decision to surgically replace the knee, a procedure called total knee arthroplasty (TKA), depends on x-ray results as well as pain and dysfunction. Despite TKA resulting in good outcomes for most patients, between 1 in 10 and 1 in 5 patients remain in significant pain - i.e., are 'TKA non-responders'. Two pain conditions - myofascial pain syndrome (MPS) and central sensitization - frequently coexist with signs of OA and may contribute to a TKA non-responder profile. MPS, caused by knots within skeletal muscle, can contribute to an OA patient's pain and dysfunction. In central sensitization, faulty pain sensing leads to increased pain sensitivity. However, there is currently no established process to identify these sources of pain and potential associated TKA non-responder risk. Our research aims conduct a pilot study to examine the impact of pain diagnosis tools to help orthopedic surgeons identify potential TKA nonresponders. This new approach may increase healthcare efficiency (reduce TKA waitlist and length of hospital stay), and help patients receive the right care at the right time.
Chronic pain after thoracic surgery has been a bothering problem since the era of thoracotomy. The prevalence of chronic pain no matter in thoracotomy or video-assisted thoracoscopic surgery is about 30 to 47%. Better acute pain control after thoracic surgery has been assumed to be an effective way for prevention of chronic pain. Especially in this extreme minimal invasive surgery, uniportal video-assisted thoracic surgery, more optimized perioperative analgesics should be found out. In the guideline of "enhanced recovery after surgery", less opioid is suggested. Other than opioids, there are just few parental analgesics could be used, like acetaminophen or cyclooxygenase-2(COX-2) inhibitor. In our study, the investigators would like to build up a better analgesic strategy for uniportal video-assisted thoracoscopic surgery with less opioid and less side effects.
Postsurgical pain becomes chronic when it lasts more then two months after surgery. A neurogenic or neuropathic pathogenesis is hypothesized for this event that reaches high rates after urologic and gynecologic surgeries. Palmitoylethanolamide (PEA) binds to mast cells and regulates pro-inflammatory factors release, without adverse events. The investigators assume that perioperative administration of PEA can reduce chronic postsurgical pain incidence of patients undergoing to urologic and gynecologic elective surgery.
