Ideal new treatments for Novel Coronavirus-19 (COVID-19) would help halt the progression disease in patients with mild disease prior to the need for artificial respiration (ventilators), and also provide a rescue treatment for patients with severe disease, while also being affordable and available in quantities sufficient to treat large numbers of infected people. Low doses of Naltrexone, a drug approved for treating alcoholism and opiate addiction, as well as Ketamine, a drug approved as an anesthetic, may be able to interrupt the inflammation that causes the worst COVID-19 symptoms and prove an effective new treatment. This study will investigate their effectiveness in a randomized, blinded trial versus standard treatment plus placebo. Read Less

The primary goal of the project is to study the effect of Ketamine on cortical neurophysiological function in TRD patients. The proposal employs robust and non-invasive neurophysiological techniques TMS and EEG to investigate the cortical excitability and oscillatory activity in patients with treatment resistant depression.

The purpose of this study is to prospectively study the efficacy of low dose ketamine infusions in treating patients who are admitted to the hospital with a sickle cell pain crisis. Participants will be prospectively randomized in unblinded fashion in the first 12 to 24 hours of an inpatient admission for sickle cell pain crisis to receive pain management without ketamine infusion (Group A) versus pain management that includes low-dose ketamine infusion starting at 0.2mg/kg/h (Group B). The effect of this intervention on various pain management and healthcare utilization outcome measures will be recorded and analyzed to determine whether or not there is a measurable benefit of using ketamine infusions in this patient population.

BACKGROUND: Current treatment standard for acute pain crisis in sickle cell disease (SCD) is largely supportive care: opioid analgesics, hydration, oxygen, and blood transfusion. Sickle cell disease (SCD) is a chronic condition associated with serious and disabling acute consequences such as a vaso-occlusive (VOC) or pain crisis. Uncontrolled pain is the hallmark of a VOC, and often results in acute unscheduled care in the patient's clinic or hospital emergency department (ED). During these pain crises, patients sometimes require high doses of opioids for analgesia. Opioid analgesics are fraught with challenges including the development of tolerance, dependence, and opioid-induced hyperalgesia (whereby the use of opioids actually makes patients more sensitive to pain). Finding non-opioid alternatives for intravenous analgesia is problematic based on the limited availability this class of drugs. Ketamine is a potent N-methyl-D-aspartate (NMDA) receptor antagonist that even at low doses has demonstrated efficacy as an adjunct to opioids for acute pain control. OBJECTIVE: The investigators will determine the comparative efficacy of low doses of ketamine as an adjunct to opioids versus standard care (opioids alone) for the treatment of acute severe pain in patients with sickle cell related pain crisis. METHODS: The investigators propose a double-blinded, randomized, placebo-controlled pilot study to determine the efficacy of ketamine 0.3mg/kg vs. placebo for the treatment of acute pain crisis. The investigators will include all eligible emergency department ≥18 years. The investigators will stratify 42 patients by location, 21 patients per site. Numeric Rating Scale (NRS) will be recorded as a part of the study log at 0, 1, 2 and 3hrs after the study drug administration. HYPOTHESIS: The investigators hypothesize that the ketamine will decrease overall pain intensity, visit length of stay, and hospitalizations. Read Less

The purpose of this study is to examine the effectiveness of a single infusion of ketamine (KET), to determine which dose is optimal 7 days after infusion using Bayesian Adaptive Randomization, and to learn about how ketamine works in the body and brain in persons with late-life treatment resistant depression.

Patients undergoing major spinal surgery continue to experience moderate-to-severe pain during the first 2-3 days following the operative procedure. Several factors contribute to postoperative pain in this patient population. Many patients present to surgery dependent on relatively high doses of oral opioids; this daily administration leads to tolerance to the effects of these drugs as well as hyperalgesia (exposure to opioids makes subsequent pain worse). In addition, surgical procedures on the spine are very painful. Furthermore, most of the opioids used after surgery only produce analgesia (pain relief) for 2-4 hours, which leads to fluctuations in levels of pain control (patients have to push a button to deliver pain medication when they begin to feel discomfort). Recent data suggest that the use of a long-acting opioid like methadone in the operating room, which provides analgesia for 24-36 hours, may improve pain control after spinal fusion surgery. However, other pain treatment modalities are required in this patient population. Studies have demonstrated that ketamine, a drug that prevents pain by a mechanism different from opioids, is effective in reducing pain medication requirements when given in the perioperative period. Small-dose infusions not only provide analgesia, but also prevent opioid tolerance and hyperalgesia. In particular, the combination of methadone and ketamine may be especially effective in controlling pain in patients following major operations. The aim of this randomized clinical trial is to examine the effect of a low-dose perioperative infusion of ketamine, when given with methadone in the operating room, on postoperative pain medication requirements, pain scores, and clinical recovery characteristics after spinal fusion surgery.

Patients who are having problems breathing sometimes require placement of a breathing tube in their mouth and windpipe. The purpose of this breathing tube is to save the patient's life. It is common to give the patient a medication to sedate him or her before the breathing tube is placed. For patients who are gravely ill two medications are commonly used: etomidate or ketamine. Both medications have risks and benefits. Researchers at UT-Southwestern Medical Center and Parkland Memorial Hospital would like to do a study to figure out which one is better for our patients.

The purpose of this project is to test how ketamine, an analgesics currently employed in the pre-hospital setting by the US Army, alters the capacity to tolerate a hemorrhagic insult in humans. Read Less

The purpose of this study is to compare the hemodynamic effects of ketamine v etomidate during rapid sequence intubation (RSI) in the pre-hospital and emergency department setting. Read Less

This study evaluated the efficacy and safety of the compound MIJ821 compared to placebo in patients aged from 18 to 65 years diagnosed with treatment-resistant depression. The study was conducted in the US and in Europe (Spain). The MIJ821 was administered via infusion on a weekly or bi-weekly basis. The efficacy was measured after 24 hours using a specific golden standard scale, the Montgomery-Asberg Depression Rating Scale. The study duration was 6 weeks of treatment plus 1 month of follow up period. Read Less
