Filter by:This research is being done to compare two methods of giving fentanyl, a narcotic often given to patients following brain surgery and determine if one method has more side effects than the other. Both of these methods are available in the postoperative treatment of pain. This research also is being done to determine if patients receiving narcotic pain medicine will benefit from additional monitoring of carbon dioxide levels. Since narcotic pain medicines can slow down breathing, we want to see if measuring exhaled carbon dioxide levels will help identify a slower breathing rate and improve safety.
Long-term opioid therapy is commonly administered for the management of severe cancer pain. Increasing doses of opioids are titrated against effects until analgesia is achieved or intolerable adverse effects occur. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has been reported to improve analgesia in patients with uncontrolled pain receiving high doses of opioids. This study aims at determining the effectiveness of ketamine as an adjuvant to opioids in relieving cancer pain.
This study tests whether education about memory and pain might help to prevent aggression in persons with dementia who have pain. The overall goal of this intervention is to reduce the risk of aggressive behavior by improving several areas of patient life that are known causes of aggression: pain, depression, lack of pleasurable activities, caregiver stress and difficulty in caregiver-patient communication.
The purpose of this study is to characterize the safety, PK, and efficacy of BTDS in patients of ages 7 to 16 years.
The pathophysiology of pain related to fibromyalgia is not understood. This condition is difficult to diagnose and to treat. One clue may be that tender points (areas which hurt typical of fibromyalgia) are most densely located near the clavicles. This is also the area where brown fat is located in humans. Brown fat is typically used to maintain body temperature. Stress (such as cool temperature or special diets, i.e., high fat, low carbohydrate) appears to worsen the pain seen in fibromyalgia. We hypothesize that a mechanism for pain in this disease relates to activating brown fat through neural mechanisms. The nerves to brown fat also go into adjacent muscle and skin. So, when brown fat is turned on or increases in amount, collateral nerves may cause pain at the tender points. The central hypothesis is that stress such as temperature or diet will activate brown fat. Patients with fibromyalgia will have greater activation or volume of brown fat. Neuralgia related to stress may be the etiology of the pain. If this hypothesis is proven, there are several drugs on the market that could be deployed to correct these patients' problems. Therefore, this project, if successful, will lead to clinical trials of these drugs in fibromyalgia patients.
The purpose of this study is to evaluate the tolerability and safety of oral morphine sulfate in the treatment of postoperative pain in different pediatric age groups following multiple-dose administration. To determine multiple-dose pharmacokinetics (PK) of morphine sulfate in pediatric subjects. To compare plasma concentration of morphine sulfate in each age group of pediatric subjects with adult plasma morphine sulfate concentrations.
Background of the study: Treatment of Pain in Head-and-Neck Cancer Patients: is methadone more effective than fentanyl? Pain is a prevalent symptom in patients with cancer. A neuropathic component is seen in one third of the patients. In patients with head-and-neck cancer neuropathic pain is far more prevalent than in a general cancer population: 46-64%. Treatment of neuropathic pain is complex and available treatment modalities achieve (partial) pain relief in only 40-60% of patients. The N-Methyl-D-Aspartate Receptor (NMDAR) plays a central role in the mediation of neuropathic pain. NMDAR blockers could be a new approach to treat neuropathic pain in patients with cancer. Methadone is a strong opioid but at the same time significant non-competitive NMDA-receptor antagonist qualities have been described. Many small studies and case-reports describe the successful rotation from different strong opioids to methadone. There are no studies that selected patients with (predominantly) neuropathic pain to be treated with methadone, whereas this group of patients is expected to profit from the NMDAR-antagonist properties of methadone. Objective of the study: This randomised controlled trial (RCT) aims to investigate whether addition of a NMDAR-antagonist to a strong opioid (methadone) is superior in the treatment of predominantly neuropathic pain over a strong opioid alone (fentanyl) in terms of pain relief and time to achieve significant pain relief. Study design: Open label randomised controlled trial Study population: opioid naïve patients with histological proven head-and-neck cancer and (partly) neuropathic pain with a NRS score of ≥ 4, age =/> 18 years Intervention Treatment with methadone or fentanyl patch Primary study parameters/outcome of the study: Is methadone more effective than fentanyl in the treatment of pain in patients with head-and-neck cancer with respect to 1. significant pain relief (reduction of Numeric Rating Scale (NRS) of 50%) and 2. pain interference Secondary study parameters/outcome of the study: Is methadone superior to fentanyl in the treatment of pain in patients with head-and-neck cancer with respect to 1. time to achieve significant pain relief 2. side-effect profile?
The investigators are conducting this research to compare two different methods of closure of the sternum after cardiac surgery to determine if one method is better than the other. Open heart surgery always requires a sternotomy, and at the end of surgery the sternum needs to be closed. The sternum can be closed with Stainless Steel Wires or Sternalock rigid sternal closure system with equivocal results; however, the outcomes of these two methods have never been investigated in a randomized study. Thus, the investigators are conducting this study to compare two different methods of closure if one method demonstrates any recovery benefit over the other, using randomizing the subjects 1:1 to either rigid fixation with Sternalock or stainless steel wire closure. Recover benefit will be measured by postoperative intubation time, length of intensive care unit stay, and overall postoperative length of stay
This study is designed to assess bioequivalence between one test and two reference formulations used for treatment of headaches and temporary relief of pain.
The study hypothesis is that infusion of 2% lidocaine at the time of IUD placement will reduce pain scores related to that procedure. In a double blinded randomized trial of 60 women receiving either normal saline or lidocaine infused through an endometrial aspirator, pain scores will be obtained for each step of the IUD placement procedure and for the total experience.
