Active clinical trials for "Nociceptive Pain"

A Phase 1 double-blind, placebo-controlled, randomized single ascending dose incorporating an open-label, 2-period crossover, food effect cohort.

This study will investigate the potential of guiding remifentanil analgesia during cardiac and vascular surgery in moderate to high risk patients requiring general anesthesia.

The purpose of this study is to evaluate the safety of long-term treatment with HZT-501, a fixed-dose combination oral tablet of 800 mg ibuprofen and 26.6 mg famotidine for patients that require long-term NSAID treatment.

This prospective randomized clinical trial evaluates the effects of a monitor-guided opioid analgesia during general anesthesia. To date no standard-monitoring device exists to specifically reflect the analgesic component of general anesthesia. Quality and safety of general anesthesia are of major clinical importance and should be improved by limiting the opioid analgesic's dosage to the minimum amount needed. The study compares the effects of monitoring nociception during general anesthesia with different innovative techniques in comparison to routine clinical practice.

Fibromyalgia Syndrome (FMS); is a complex syndrome characterized by many symptoms such as chronic widespread pain, fatigue and sleep disorders, cognitive dysfunctions and psychiatric disorders. It has been stated that there is an urgent need for studies examining the clinicimetric and psychometric properties of the pain phenotype criteria in terms of patients receiving the most appropriate treatment, clinicians deciding on the appropriate treatment, and contributing to the research of scientists. Despite all this, no study has yet been found that describes the pain phenotypes in fibromyalgia syndrome and how different types of pain affect patients. The primary aim of this study is to determine the chronic pain phenotypes in individuals with FMS. The secondary aim of this study to determine the inter-rater and intra-rater reliability of the algorithm used in the determination of pain phenotypes and to assessment the clinical effects of different pain phenotypes on individuals with FMS in terms of pain severity, disease severity, quality of life and catastrophe.

A Phase 1, placebo-controlled, two part study with either single dose or multiple increasing oral dose to evaluate the safety, pharmacokinetics, and pharmacodynamics of CNTX-6970 in healthy subjects.

Background: Analgesia remains to this day a challenge for anesthesiologists. Dexmedetomidine, a potent central alpha-2 agonist, has been shown to have analgesic and opioid sparing effects. The classic analgesic strategy focuses on opioid administration guided by estimated time of elimination and hemodynamic response (increase in blood pressure and heart rate). This technique is not sensitive and forces the anesthesiologist to be one step behind nociception, the patient's unconscious response to pain. PMD-200 (Medasense, Israel) displays the Nociceptive level (NOL)-Index as marker of nociception. The NOL-Index ranges from 0 (no nociception) to 100 (intense nociception) and the recommended analgesic range during surgery is from 10 to 25 (Medasense recommendations). The goal of this study is to compare two analgesia strategies guided by the NOL Index (range 10-25) using either remifentanil TCI (target controlled infusion) alone or remifentanil TCI associated with a continuous dexmedetomidine infusion. Methods: A total of 100 patients will be included and informed consent will be acquired. This bi-center study will take place at Erasme University Hospital (primary center) and Saint-Pierre University Hospital. Patients will be randomized into either two groups: remifentanil and placebo versus remifentanil and dexmedetomidine. Both groups will be monitored using the PMD-200 that will guide the analgesic therapy strategy. Investigators and patients will be blinded to dexmedetomidine and placebo administration. The primary outcome will be intraoperative remifentanil consumption. Secondary outcomes will include postoperative opioid administration, opioid associated complications, hemodynamics, and hospital length of stay.

Previous work has shown that NOL (Medasense, Ramat Gan, Israel) accurately quantifies nociception during general anesthesia. Presumably, titrating opioids to NOL will therefore provide individual guidance so that patients will be given about the right amount. Patient given the right amount will presumably awaken quickly when anesthesia is done, and have good initial pain control in the post anesthesia care unit (PACU). To the extent that NOL titration facilitates optimal opioid dosing, patients are likely to have better PACU experiences - which would be an important outcome that clinicians and regulators are likely to take seriously.

Prospective Randomized Monocentric Clinical Trial during propofol anesthesia. The aim of the study is to test whether the use of a medical device designed to automatically administer remifentanil during surgery based on expert rules and continuous reading of heart rate, blood pressure and the Analgesia Nociception Index results in lower overall remifentanil administration versus standard practice.

This study evaluates the potential association between pain catastrophizing thoughts and the ability to dampen pain via endogenous descending inhibition. Half of the participants are persons with chronic low back pain and the other half are age and gender-matched controls
