Active clinical trials for "Acute Pain"

The main objective of this trial is to demonstrate the efficacy and safety of multiple-dose application of oral application of CG5503 IR 75mg compared to placebo and to assess safety and tolerability of CG5503 IR 75mg in subjects following bunionectomy. This trial was performed based on a previously performed double-blind, placebo-controlled, multiple-dose trial in the same indication investigating 3 dose strengths CG5503 IR (50, 75 and 100 mg) published under PMID: 18851776.

The purpose of this study is to evaluate the effectiveness (level of pain control) and safety of the administration of 2 different dose levels of tapentadol (CG5503) compared with oxycodone and with placebo in subjects who have had a bunionectomy.

This study will evaluate how genetic makeup contributes to the variation in people regarding their sensitivity to and experience of pain. Scientists believe that differences in information found in genes may explain why an analgesic drug, that is, one that treats pain, works effectively for some people but not for others. The study will explore pain that is acute (fast and short period). Knowledge gained from this ongoing study may permit development of an individualized analgesic drug prescription. Patients ages 16 to 35 who are in good health and have been referred for removal of impacted wisdom teeth; who are not allergic to aspirin or other nonsteroidal anti-inflammatory drugs (known as NSAIDs), sulfites, or certain anesthetics; who are not pregnant or nursing; and who are willing to have a biopsy before and after dental surgery are eligible for this study. Patients will come to the clinic for one test visit and one treatment visit. During the first visit, a questionnaire will evaluate patients' psychological state, including mood and depression. There will be a clinical examination of their wisdom teeth. A blood sample of 10 milliliters (about 0.4 ounces) will be collected from the forearm to provide DNA material containing genes stored in cells. The primary genetic analysis will be done at NIH, although the DNA collected might also be sent to a laboratory outside NIH. DNA samples will be coded so that names of patients cannot be traced. During the second visit, two of the patients' lower wisdom teeth will be removed. Patients will be given a local anesthetic in the mouth and a sedative given through a vein in the arm. While the mouth is numb, a small piece of tissue will be removed from inside the cheek, near the wisdom tooth. It is the first biopsy. After the two wisdom teeth are removed, a small piece of tubing will be placed into both sides of the mouth where the teeth were removed. Every 20 minutes, for the next 3 hours, the researchers will collect inflammatory fluid from the tubing, to measure the chemicals thought to cause pain and swelling. Also every 20 minutes, patients will rate the pain they feel by answering questions. If there is pain before 3 hours following surgery, they will receive a dose of fentanyl to relieve moderate to severe pain. A second biopsy will occur 3 hours after surgery, to measure changes in chemicals produced in response to surgery. Immediately afterward, patients will receive 30 mg of ketorolac (Toradol) whether or not pain is felt. They will answer questionnaires about pain for 3 hours after receiving the drug, to rate how well it works. They will stay at the clinic up to 6 hours after the surgery. If pain is not relieved with ketorolac, patients will receive a one-time dose of tramadol, a pain medication for moderate to severe pain. After the study procedures are completed, patients will receive pain medication for pain after surgery. Patients will be monitored closely, because all drugs have side effects. Ketorolac is a nonsteroidal anti-inflammatory drug, one that may cause gastrointestinal upset. Fentanyl is a powerful narcotic drug that is safe at the dosage used in this study, but stomach upset, dizziness, and breathing trouble may occur. Also, risks from the biopsy include discomfort from injecting the numbing medicine, infection, and bleeding. There may be discomfort from the sedative injected into the vein, and there may be bruising. Benefits from participating are having wisdom teeth removed at no cost as well as close monitoring before and after surgery. There are no plans to give patients the results of genetic tests or questionnaires. Years of research may be needed before such information has the chance to become meaningful.

The purpose of this study is to evaluate the effectiveness (level of pain control) and safety of the administration of 3 different dose levels of CG5503 compared with oxycodone and with placebo in patients who have had a bunionectomy, and to assess the safety of the drug for 9 days after patients are discharged from the hospital.

Prehospital management of traumatic pain is commonly based on morphine while loco-regional analgesia techniques, especially the femoral nerve block (FNB), can be safely and efficiently used. Adjuvants uses can reduce local anesthetic doses and decrease their related risk. The aim of the study was to assess the analgesic effect of Magnesium sulfate (Mg S) when used as adjuvant in prehospital FNB. This is a randomized double-blinded trial conducted in a prehospital medical department of an academic hospital. Patients with isolated diaphysial femoral fracture and eligible to participate were randomized into 2 groups. The Group Placebo had a FNB with 15 ml of lidocaine with epinephrine (300 mg) and 3 ml of normal saline. The Group Magnesium had a FNB with 15 ml of lidocaine with epinephrine (300 mg) and 3 ml of Mg S 15% (450 mg). The FNB was performed according to the WINNIE technique. Primary endpoints were morphine consumption and pain intensity during the first 6 hours. Secondary end-points were the duration of the sensitive block, time to the first analgesic request, side effects occurrence.

The goal of this randomized clinical trial is to compare the analgesic efficacy and side effect profile of IV acetaminophen as an analgesic adjunctive medication to IV hydromorphone for the treatment of acute pain experienced by patients in the Emergency Department (ED).

The investigators propose a pilot clinical trial on the use of perioperative pregabalin in order to decrease ureteral stent related symptoms and decrease opioid usage after ureteroscopy with stent placement. Patients undergoing ureteroscopy with stent placement will receive a single dose of 300 mg pregabalin PO in the preoperative area. This work will assess safety and feasibility of studying this regimen at our institution, with the aim of performing a randomized, placebo-controlled, double-blinded study in the future.

The aim of this clinical study in healthy participants is to investigate the safety and tolerability of GRT0151Y after multiple oral intake of different increasing doses and to evaluate the pharmacological effects (action of the compound) by means of pupillometry (measuring the pupil size of the eye) and Cold Presser Test (measuring the pain when immersing the hand in 2 degree Celsius cold water). An additional aim of the study is to investigate the pharmacokinetics of GRT0151Y (how it is taken up into the body and how it is excreted from the body)."

A phase 4 randomised, double-blind study to assess the efficacy and safety of Penthrox® used from the outset in multimodal analgesia, in combination with the standard analgesic protocol used in the department, for conscious adult patients presenting in an emergency department with moderate to severe pain associated with a trauma

The study is comparing the difference between erector spinae block and surgeon infiltration after VATS (Video Assisted Thoracoscopic Surgery). The outcomes measured are pain scores, opioid usage, opioid side effects, and patient satisfaction.We are also also studying the effectiveness of liposomal bupivacaine (EXPAREL) in a block by randomizing patients to both EXPAREL erector spinae block and simple bupivacaine erector spinae block.
