Around 3 out of 4 operations in the UK are performed as day-case, meaning the patient goes home on the same day of their operation. Hospitals usually do not follow up patients after day-case operations so we do not know very much about their short or long-term recovery. Some patients, even those who have had small operations, can develop persistent pain afterwards that continues for a long time (months to years). These patients may end up taking strong painkillers for a long time and this risks serious side effects and long-term health problems. The POPPY study aims to find out what recovery from day-case operations is like from the patient's point of view. We will look at the first week after patients' operations and then at 3 months to see if they are in pain, and if so what pain relief they are taking. All adults over the 5-day study period having day-case operations in the UK, with an anaesthetist, will be eligible if they have access to a smartphone. Patients will be recruited on the day of their operation from over 100 NHS hospitals. Some relevant information about the patient's current health, operation and anaesthetic will be recorded from their notes. Afterwards participants will get a text message at days 1, 3 and 7 and the at 3 months. These will connect to a data secure online questionnaire about pain, recovery, and what medications they are taking. A small number of participants with ongoing pain at 3 months will be invited to take part in a structured interview to understand their experience in more depth. This study will provide important information that may be used to improve care of patients having day-case operations and plan future research studies aimed to prevent persistent pain and long-term use of strong painkillers.
Investigators will test, for safety and efficacy, a novel treatment for opiate addiction that applies a 4-minute treatment of intense near infra-red light to stimulate a side of the brain that the investigators determine to be healthier, more mature, and less traumatized. Investigators will compare among actively using participants an active and a sham treatment given either once or twice weekly for 25-weeks at 2 sites. Investigators hope this will lead to a significant weapon in the battle against the opioid epidemic as well as lead to psychological and physiological insights into possible relations among trauma, cerebral laterality, and addiction.
A placebo-controlled trial in which male and female outpatients with an opioid use disorder who express interest in extended-release injectable naltrexone (XR-NTX) are randomized 1:1 to lofexidine/pregabalin or lofexidine/pregabalin placebo for withdrawal management and offered XR-NTX if after completing withdrawal.
The goal of this interventional clinical trial is to assess opioid consumption 24-48 hrs post anesthesia block among patients undergoing total knee arthroplasty. The main question it aims to answer is: 1. Is there a difference in opioid consumption 24-48 hours post block administration among patients that receive an adductor canal catheter (ACC) versus adductor canal block (ACB)? Participants will be: - Randomized to receive an adductor canal catheter (ACC) or a sham adductor canal catheter. - Asked to use the Diagnotes application to communicate with the pain doctor while the catheter is in place. - Follow up for up to 6 months post-operation. Researchers will compare the interventional group (ACC) to the control group (sham ACC + ACB) to see if there is difference in opioid consumption and chronic pain at 6 months post-operation.
The goal of this randomized controlled trial is to examine if there is a relationship between the addition of the genicular nerve block and anterior femoral cutaneous nerve block in providing analgesia and the use of oral and intravenous medication in patients undergoing a total knee arthroplasty. The main questions it aims to answer are: 1. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' total opioid consumption in the first 24 hours after total knee arthroplasty (TKA) surgery? 2. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' worst numeric rating scale (NRS) pain score in the post-anesthesia care unit (PACU)? 3. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care result in earlier discharge from the post-anesthesia care unit (PACU)? 4. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' total opioid consumption in the first 7 days after total knee arthroplasty (TKA) surgery? 5. Does incorporating genicular nerve block and anterior femoral cutaneous nerve block to our current standard of care reduce patients' numerical rating scale (NRS) pain (both at rest and during movement) in the first 24 and 48 hours after surgery? Participants will be randomly assigned to receive the genicular nerve block and anterior femoral cutaneous nerve block in addition to standard of care (intervention group), or not receive the nerve blocks (control group). Comparing the intervention group to the control group, the researcher's primary outcomes are numerical pain in the post-anesthesia care unit and cumulative opioid consumption during the first 24 hours.
The overall goal of this project is to collect initial human data on the effects of novel compounds on safety (interactions with an opioid drug, e.g., buprenorphine) and early efficacy signals (subjective effects on negative affect, craving, and opioid withdrawal) in OUD subjects currently in MOUD treatment with buprenorphine.
The aim of this study is to investigate the effects of intravenous infusion of lidocaine at different doses (1 mg/kg/h vs. 2 mg/kg/h) in the intraoperative period in patients undergoing lumbar stabilization, whether postoperative pain, postoperative opioid use, opioid-related side effects are reduced, and its effects on intraoperative hemodynamics
The goal of this randomized controlled trial is to compare laparoscopic guided peri-wound Transversus Abdominis Plane Block and bupivacaine versus local wound infiltration effect on reducing post-op opioid use in Laparoscopic Sleeve gastrectomy. The main questions it aims to answer are: • Can laparoscopic guided peri-wound Transversus Abdominis Plane Block reduced post operative morphine usage when comparing with local wound port site infiltration. Participants will be randomize into 2 group - peri-wound Transversus Abdominis Plane Block - local wound port site infiltration
The goal of this clinical trial is to demonstrate the commercial potential for a novel virtual reality (VR) intervention in preparation for Phase II development. This clinical trial will test the VR intervention for efficacy in reducing opioid use, increasing abstinence, and other self-reported and behavioral focus on future outcomes in individuals in early recovery from opioid use disorder. - Will the VR group, compared to the control group, have a lower number of opioid use days? - Will the VR group, compared to the control group, have longer periods of abstinence at the 30-day follow-up? - Will the VR group, compared to the control group, have significantly increased opioid abstinence rates? - Will the VR group, compared to baseline and the control group, show increased future self-identification post-VR intervention? - Will the VR group, compared to baseline and the control group, show increased future orientation post-VR intervention? - Will the VR group, compared to baseline and the control group, show an increased preference for delayed rewards in a laboratory delay discounting task post-VR intervention? - Will the VR group, compared to baseline and the control group, exceed in behavioral effects (i.e., future self-identification, future orientation, and increased preference for delayed rewards) at the 30-day follow-up? Researchers will compare the VR test group and the control group to see if there are differences in the results for the questions outlined above.
