Ketamine Treatment Options

This is a prospective, randomized study of ketamine versus no ketamine in approximately 100 patients undergoing hemorrhoidectomy for Grade III or IV hemorrhoids. The participants will be blinded to which treatment arm they are assigned, because participants will be under anesthesia when the ketamine is administered. The investigators will know whether the participant receives ketamine or not. Read Less

To compare the outcomes of the use of propofol, etomidate, and ketamine as induction agents for adult trauma patients undergoing intubation within 24 hours of admission. The primary goal is to determine the ideal agent that should be used in this patient population for intubations. Read Less

Investigators are comparing Ketamine to prochlorperazinecompazine for benign headaches in the ED. Subjects will be randomized into 1 of 2 groups. Group 1 will receive standard treatment of prochlorperazinecompazine 10 mg IV along with diphenhydramine 25 mg IV. Group 2 (research arm) will receive Ketamine 0.3 mg/kg along with ondansetron 4 mg IV. Subjects will be seen at 15, 30, 45, and 60 minutes post-intervention to obtain Heart Rate, Blood Pressure, Headache severity, Nausea severity, Vomiting severity, Anxiety severity, and Restlessness severity. At 24-48 hours post intervention we will contact subjects and assess their pain and assess their satisfaction with their migraine pain management as part of this study. Subjects' participation will last up to 48 hours post headache. Read Less

This study has two aims: 1) to characterize the effects of intravenous ketamine on neurocognitive markers in depressed patients; 2) to test the efficacy of a synergistic intervention for depression combining intravenous ketamine with neurocognitive training. Three of the primary outcomes listed (fMRI functional connectivity; Implicit Association Test; cognitive flexibility testing) pertain to Aim 1. For Aim 2, one primary clinical outcome (MADRS, a clinician-administered measure of depression severity) pertains to the acute (30-day) phase, while the QIDS (a self-report measure of depression severity) becomes the primary clinical outcome during the 12-month naturalistic follow-up.

Ketamine-Assisted Psychotherapy (KAP) is a relatively new approach for the treatment of mental health issues, which involves the combination of ketamine, a dissociative anaesthetic with psychedelic properties, and psychotherapy to promote emotional wellbeing. In this study, we investigated the effectiveness of KAP in adult patients coping with mental health. We predicted that clients would experience lasting reductions in psychological distress over time, such as depression, anxiety, and post traumatic stress, that would be detectable up to 6 months after treatment. The results of this study may provide evidence of sustained real-world effects of Ketamine-Assisted Psychotherapy, of interest to patients, clinicians, researchers, and policymakers. Read Less

The goal of this clinical trial is to learn about the effect of ketamine on intraoperative motor evoked potentials in adult patients undergoing thoracolumbar spinal fusions. Participants will undergo a standard anesthetic. In addition to the standard anesthetic, the patients will be administered increasing doses of ketamine with motor-evoked potentials being measured at each dose, to assess any impacts. Read Less

The purpose of this research is to determine the pain-reducing effects of ketamine (Ketalar, an FDA-approved drug for anesthesia) and methadone (Dolophine, a long-acting narcotic) after lumbar laminectomy. The investigators would like to evaluate whether intraoperative use of both drugs may be able to provide better control of pain after lumbar surgery. Read Less

The incidence of opioid use disorders (OUDs) has increased to near-epidemic proportions. While maintenance with long-acting opioids such as methadone or buprenorphine represents an effective treatment strategy, it may be unacceptable to many individuals. As a result, long-acting injectable naltrexone (XR-NTX), an antagonist medication that blocks the effects of opioids for at least 4 weeks, is now indicated for relapse prevention following detoxification. This randomized, controlled trial aims to test the efficacy of a glutamate modulator at facilitating a rapid non-opioid based naltrexone induction. Read Less

The goal of this clinical trial is to examine the use of sedative ketamine to treat depression and post-traumatic stress disorder (PTSD) in Veterans with mild to moderate traumatic brain injury (TBI). The main questions it aims to answer are: * Efficacy of ketamine to reduce symptoms of depression and/or PTSD * Safety of ketamine to treat depression and/or PTSD in TBI Participants will be randomly assigned to receive either ketamine or midazolam (active placebo) twice a week for 3 weeks. During participation, subjects will be interviewed, have lab tests, and complete rating scales, and questionnaires. Read Less

This is a pilot study to evaluate pain responses from two different approved medications (ketamine and fentanyl) in the treatment of pain after rattlesnake envenomation (RSE). Both medications are currently used in standard practice to treat both acute and chronic pain and are options for pain management after RSE. Multiple studies exist showing ketamine to be both safe and effective for the treatment of acute pain, and to be as good as or better than opioids for this indication. The specific comparison of ketamine to fentanyl, however, has never been studied for the treatment of acute pain after rattlesnake envenomation in the United States. The investigators plan to measure pain scores after a single dose of ketamine or fentanyl in patients shortly after being envenomated, followed by continued treatment of pain guided by the treating doctor. There will be no restrictions on additional pain medications given and no other changes to the treatment of these patients during their hospitalization. This research is important because pain after RSE can be difficult to control and may require frequent, high doses of opioids for several days. An effective non-opioid medication would be helpful both to better-control pain and to reduce exposure to opioids in this patient population. This study will compare patient-reported pain scores after receiving a single dose of ketamine or fentanyl in patients with rattlesnake bites who have been admitted to the toxicology service at Banner - University Medical Center Phoenix (BUMCP).

Patients with head and neck cancer generally receive a standard of care of 7 weeks of daily radiation therapy given alongside an aggressive chemotherapy drug called cisplatin. While rates of cure are often strong for patients who are able to complete treatment without any unscheduled breaks, the rates of high grade toxicity associated with this treatment are high even with the use of the most modern techniques of treatment. Pain, swallowing dysfunction, loss of taste sensation, and ulceration of the mouth and throat are ubiquitous and often contribute to a nutritional breakdown requiring feeding tube placement. Unfortunately, even with aggressive use of opioids and other conventional palliation methods, breakthrough pain and other toxicities are very common. In addition to the quality of life burdens of these side effects, patients who are unable to complete treatment on schedule have worse control of their cancer and worse overall survival. Clearly, there is a clinical need for better management of these toxicities. The investigators hypothesize that ketamine mouthwash may effectively reduce both pain and the need for opioid drugs in this patient population. There is a large body of literature supporting the use of ketamine for pain control in diseases other than cancer, and a smaller but growing body of literature showing the effectiveness of ketamine for control of cancer-associated pain. Additionally, by providing ketamine in mouthwash form, the evidence shows that one can avoid the side effects associated with giving ketamine throughout the body, and in fact no significant side effects have been reported so far with this treatment. In this study, the investigators will provide ketamine mouthwash to patients undergoing the standard treatment for this disease over a two week period, and measure their response in terms of both pain and need for opioids, as well as other measurements of quality of life. The investigators will also measure unscheduled interruptions in treatment. In years to come, the data from this study may show an impact on cancer control and survival. Read Less

NMDA antagonist drugs have increasingly been demonstrated to reduce symptoms of depression and suicidal ideation. NeuroRx has developed a sequential therapy consisting of IV NRX-100 (ketamine HCL) for rapid stabilization of symptoms of depression and suicidal ideation followed by oral NRX-101 (fixed dose combination of D-cycloserine and lurasidone) for maintenance of stabilization from symptoms of depression and suicidal ideation. This study will test the hypothesis that that NRX-100 is superior to placebo in achieving rapid reduction in symptoms of depression and suicidal ideation in patients with Severe Bipolar Depression and Acute Suicidal Ideation or Behavior within 24 hours of administration.
