Filter by:Opioids remain the first-line drugs for the treatment of moderate to severe postoperative pain, but the use is limited by well-known side-effects, most of which are dose-dependent. The opioid oxycodone is standard therapeutic treatment for acute postoperative pain, either in immediate-release formulation, OxyNorm®, or as extended-release formulation, OxyContin®. Oxycodone provides analgesic effects through µ-opioid receptors in the central nervous system. Tapentadol hydrochloride/depot (Palexia/depot®) is a novel, centrally acting, strong analgesic with a dual mechanism of action on µ-opioid receptors and noradrenaline reuptake in the central nervous system. Tapentadol is an active compound, devoid of active metabolites and not reliant on enzyme systems. For these reasons, it has a low drug interaction potential. This dual mechanism also translates clinically into less adverse effects than with pure opioid agonists like oxycodone. This is probably due to less µ-opioid receptor stimulation. Tapentadol has been shown effective in models of acute, osteoarthritic, neuropathic and cancer pain. There is now an increasing use of tapentadol in postoperative pain treatment in Norway. However, there is a lack of broad-based evidence for the use of tapentadol in the post-surgical setting. So far, to our knowledge, there are only published studies on postoperative pain treatment after orthopedic and dental surgery, but none related to deep abdominal pain. Tapentadol is shown in several studies on chronic pain patients to have comparable analgesic effects to traditional opioid pain medications like oxycodone and morphine, but with a more tolerable side-effect profile. In the postoperative setting after dental or orthopedic surgery, studies have shown less nausea and constipation. It has also been suggested a lower frequency of pruritus compared with oxycodone, but no difference in central nervous system symptoms such as sleepiness or dizziness. The most dangerous side-effect from opioids is respiratory depression with the potential of fatal outcome. The investigators have not found any publications from short-term postoperative pain management comparing the respiratory effect of tapentadol to the traditional opioids. The aim of the study is to compare the analgesic effect and side-effects of this new analgesic, tapentadol, to the standard treatment to day, oxycodone, in the acute postoperative period after hysterectomy.
The societal impact of heavy alcohol consumption and chronic pain is substantial and warrants the existing research investment into their etiology and treatment. Moreover, evidence of significant co-occurrence between these conditions offers an opportunity to examine mechanisms in the alcohol-pain connection that may inform the development of novel treatments. Consistent with NIH PA-15-026 (Mechanistic Studies of Pain and Alcohol Dependence), the goal of the proposed study is to examine several complex and potentially bidirectional relations between pain and alcohol in one overarching model, which has never been attempted in a human experimental paradigm. The primary study aims are as follows: (1) to conduct the first test of both pharmacological and expectancy effects in acute alcohol analgesia among humans; (2) to conduct the first test of pain as a proximal antecedent of urge to drink and ad lib alcohol consumption, and to test whether acute analgesic effects predict pain-induced alcohol urge/consumption; (3) to test associations between study outcomes and candidate genetic polymorphisms that have been implicated in pain-alcohol processes; and (4) to conduct exploratory analyses of gender and pain relevant cognitive-affective factors as moderators of these outcomes. Participants will include 280 moderate-to-heavy drinkers recruited from the local community. Experimental methods will include alcohol administration (moderate dose vs. low dose vs. placebo vs. control) and pre/post assessment of static/dynamic pain responses, and capsaicin/heat pain induction (vs. no pain induction) followed by assessment of urge to drink and ad lib alcohol consumption. By employing a novel experimental paradigm, the study results will provide internally valid data with clear and direct implications for translating these findings to clinical applications. It is our expectation that this work will catalyze future research and inform clinical practice by establishing an experimental platform that allows for the demonstration of causal effects, the evaluation of treatment components prior to conducting costly clinical trials, and the identification of important theory-based biopsychosocial mechanisms that can inform the development of novel integrated treatments for individuals with co-occurring pain and alcohol use disorders.
Epidurals are an effective means for providing neuraxial anesthesia and analgesia. Prior studies in labor epidurals have demonstrated that a programmed intermittent bolus application of local anesthesia can improve pain control by reducing the amount of local anesthetic required as well as improve patient satisfaction when compared to continuous epidural infusions. The effects of programmed intermittent bolus of epidural local anesthetics compared to continuous epidural infusions in a surgical setting have yet to be elucidated. Our goal is to evaluate the use of programmed intermittent bolus compared to continuous epidural infusion in a surgical patient population. We plan to enroll patients already undergoing abdominal surgeries including colorectal, gynecologic, surgical oncology, urological where epidural anesthesia can be employed. The primary endpoints of the study will be the total local anesthetic consumption and total opioid consumption as surrogate markers for the quality of epidural anesthesia. Secondary endpoints are pain scores and functional measurements, patient satisfaction, and incidence of hypotension.
Postoperative pain after thoracic surgery is associated with adverse outcomes. The current strategy to prevent postoperative pain is the use of regional anesthesia and analgesic agents. In video-assisted thoracic surgery (VATS), thoracic paravertebral block has become the standard analgesic regimen which results in decreased postoperative pain and opioid consumption. The investigator would like to study the analgesic efficacy of low dose intravenous ketamine infusion during surgery in combination with thoracic paravertebral block on postoperative pain after VATS in a randomized study.
Sparing the phrenic nerve by administering ultrasound-guided low volume superior trunk block (STB) and interscalene block (ISB) for arthroscopic shoulder surgery (labral repair, stabilization, rotator cuff repair).
Post-discharge pain after total knee arthroplasty remains problematic; many patients have excessive pain at the 2 week time point (and often thereafter). Reduction in opioid use has become a national goal, due to the 'epidemic' in opioid misuse. In addition to enrolling non-opioid users, we will enroll up to 15 chronic opioid users.
Clinical trial to compare pain relief between methoxyflurane and any analgesic treatment used in usual clinical practice, in patients with trauma and associated pain, treated in Spanish emergency units.
In this double blinded randomized controlled study, the pupillary dilation reflex is used for as a nociceptive indicator for opioid administration during elective surgery under general anesthesia.
This project is a preliminary randomized controlled trial testing the potential impact of the PTSD Coach mobile application at reducing posttraumatic stress and pain symptoms among acutely injured trauma patients. Immediately following the injury, patients will be randomly assigned to use the PTSD Coach app, or to the treatment as usual condition.
This study evaluates the safety and effectiveness of Wafermine™ for post-bunionectomy or post-abdominoplasty pain over a 24 hours period. For subjects undergoing bunionectomy, 2 out of 3 subjects will receive Wafermine™ and 1 out of 3 subjects will receive placebo. For subjects undergoing abdominoplasty, 3 out of 4 subjects will receive Wafermine™ and 1 out of 4 subjects will receive placebo.
