Pain Paid Clinical Trials in California

Patients experience pain after their knee replacement surgery - and some may continue to experience persistent pain long after their knee replacement surgery. Traditional pain management strategies reply on pain medication such as opioids for pain control. However, these drugs do not work well for pain associated with movement or the the nerve pain (tingling, electrical sensations) after surgery. In addition, opioids are associated with significant side effects such as nausea, vomiting, respiratory depression, depression, cognitive dysfunction and risk of persistent opioid use. Neuropathic pain medications, such as venlafaxine are effective in managing nerve pain. Recent studies also support its potential role in acute pain management. Here, we propose a prospective randomized clinical trial 1) to evaluate the efficacy of Venlafaxine in reducing pain intensity and opioid consumption at post-operative day 1 (POD1) and 1- week after surgery, and 2) to examine whether the use of Venlafaxine will reduce the incidents of chronic postsurgical pain in TKA patients at 3-month time point.

Our current standard of care is to perform an interscalene peripheral nerve block for patients receiving rotator cuff repair surgery as it is an effective opioid-free alternative for post-operative pain control. However, many of these repairs require a supplemental incision for an open biceps tenodesis, which is not covered by the interscalene block. The intercostobrachial nerve covers this incision and is targeted by an axillary ring block or a single shot nerve block in the fascial plane between the pectoralis minor and serratus anterior muscles (otherwise termed as a PECS II block). This study will attempt to delineate if one is superior in postoperative analgesia and mitigating intraoperative stimulation by comparing an axillary ring block to a PECS II block. Patients receiving a rotator cuff repair with biceps tenodesis without histories of chronic opioid use and respiratory compromise will be eligible to be enrolled in the study. All patients will receive an interscalene block and group 1 will receive a supplemental axillary ring block and group 2 will instead receive a PECS II block. After surgery, the patients' pain score will be assessed upon PACU arrival, at 6 hours after block, and 2 weeks postoperatively. Their opioid requirements will also be assessed. Our primary outcome is pain score at 6 hours following the block. Read Less

After spinal fusion and decompression surgery there is a possible risk of developing chronic back pain. After surgery there is typically inflammation around the operation site and this inflammation can be painful and debilitating to patients. Many possible treatment plans have been incorporated to assist the patient with recovery - notably medications, physical therapy, and braces. However, few studies have looked at laser diodes that utilize high-power laser lights that are aimed at decreasing pain and inflammation. Investigators aim to look compare patients using a back brace with laser diodes within versus those who wear a normal brace used as a placebo. Investigators will also assess the patient's surgical wound to monitor the progression of wound healing while using the brace. Read Less

Opioid misuse and addiction among children and adolescents is an increasingly concerning problem. Post-surgical opioid prescriptions for commonly performed surgeries such as anterior cruciate ligament reconstruction (ACLR) increase opioid exposure in young athletes. The purpose of the current study is to determine if extended-release Bupivacaine Liposome Injectable Suspension (Exparel) is effective in decreasing at home narcotic consumption compared to standard Bupivacaine Adductor Canal Block for Anterior Cruciate Ligament (ACL) reconstruction/reconstruction for the surgical treatment of adolescents with ACL tears and concomitant pathology i.e. meniscus / cartilage injury/tear.

When a limb is severed, pain perceived in the part of the body that no longer exists often develops and is called "phantom limb" pain. Unfortunately, phantom pain goes away in only 16% of afflicted individuals, and there is currently no reliable definitive treatment. The exact reason that phantom limb pain occurs is unclear, but when a nerve is cut-as happens with an amputation-changes occur in the brain and spinal cord that actually increase with worsening phantom pain. These abnormal changes may often be corrected by putting local anesthetic-called a "nerve block"-on the injured nerve, effectively keeping any "bad signals" from reaching the brain with a simultaneous resolution of the phantom limb pain. However, when the nerve block resolves after a few hours, the phantom pain returns. But, this demonstrates that the brain abnormalities-and phantom pain-that occur with an amputation are not necessarily fixed, and may be dependent upon the "bad" signals being sent from the injured nerve(s), suggesting that a very long peripheral nerve block-lasting many months rather than hours-may permanently reverse the abnormal changes in the brain, and provide definitive relief from phantom pain. A prolonged nerve block lasting a few months may be provided by freezing the nerve using a process called "cryoneurolysis". The ultimate objective of the proposed research study is to determine if cryoanalgesia is an effective treatment for intractable post-amputation phantom limb pain. The proposed pilot study will include subjects with an existing above-knee amputation who experience intractable daily phantom limb pain. A single ultrasound-guided treatment of cryoneurolysis (or sham block-determined randomly like a flip of a coin) will be applied to the major nerves of the thigh. Although not required, each subject may return 4-6 months later for the alternative treatment (if the first treatment is sham, then the second treatment would be cryoneurolysis) so that all participants have the option of receiving the active treatment. Subjects will be followed for a total of 12 months with data collected by telephone. Read Less

The overall objective of this multi-center registry is to identify specific phenotypes of INOCA with both an anatomic evaluation (coronary angiography and intravascular imaging) and physiologic assessment with the Abbott Coroventis Coroflow Cardiovascular System, and to determine long-term outcomes.

The primary objective of this study is to prospectively determine, at 10 days after orthopedic shoulder or knee surgery, if pulsed electromagnetic field (PEMF) therapy is beneficial in reducing patient-reported post-operative pain, as measured by visual analog scale (VAS). The amount of pain medication taken daily and the physical function outcome scores after surgery and PEMF treatment will also be measured. Read Less

Proof of concept: Pilot Study A Pilot, proof of concept, observational study with a long-term goal to develop a minimally invasive wearable Remote Medication Monitor (RMM) that provides continuous, real-time data on methadone levels in interstitial fluid (ISF). An RMM could be used as a medication adherence monitor and would allow for the physician, counselor, patient, or family member to remotely verify that a physician-prescribed dose has been taken.

The purpose of the research is to assess the efficacy of postoperative immersive virtual reality (iVR) compared to a standard multimodal pain regimen including opioids and a local block on acute postoperative pain management following hip arthroscopy The primary research procedures are medical record review for demographic information, head-mounted immersive virtual reality experience in PACU, and pre-operative and post-operative surveys The study will enroll adult patients of all ages undergoing elective hip arthroscopy procedures for any diagnosis Read Less

The investigators will implement an international 2-arm online pragmatic feasibility randomized controlled trial (RCT) of a digital pain relief skills intervention "Empowered Relief: On-Demand" to reduce pain metrics, opioid craving, and opioid misuse. They will compare Empowered Relief to a no-skills digital health education ("Living Better") intervention in community-based individuals with comorbid chronic pain and prescription opioid misuse (N=220). Completion of the brief post-treatment survey is a binary measure of treatment engagement; treatment feasibility and appraisal are assessed with three items (satisfaction, perceived utility, and likelihood to use skills learned). Electronic surveys will measure opioid misuse behaviors, craving, and use; and pain intensity and psychological status at: baseline, immediately post-treatment; at post-treatment weeks 1 and 2; and months 1, 2, and 3.
