149 Clinical Trials for Various Conditions
The goal of this clinical trial is to learn if a combination of the two established sedation drugs remimazolam and fentanyl, can put the subject to sleep during a scheduled extraction procedure. The combined use of these drugs has been used in other studies involving IV sedation when the procedure is scheduled for 30 minutes or less. However, the combined use of the IV sedation drugs has not been used in a dental extraction procedure before. The main questions it aims to answer are: 1. Can the combined drugs effectively put the patient to sleep during the procedure 2. How quickly will they come out of the sedation after the procedure Participants will: 1. Receive the combined drugs during a scheduled extraction procedure anticipated to take less than 30 minutes 2. Answer survey questions related to their study experience after the extraction visit (in person) and again about 24 hours after the visit (by telephone).
The goal of this study is to characterize an electroencephalogram (EEG) biomarker for fentanyl and understand where this signal is coming from in the brain. The investigators also aim to understand how this EEG biomarker is connected to patient perception to drug liking.
The goal of this clinical trial is to learn if buprenorphine can be started for opioid use disorder with fentanyl use without requiring or precipitating opioid withdrawal. To be eligible, participants must have moderate or severe opioid use disorder and must have fentanyl detected on a urine drug test. Participants will be admitted to a monitored research unit for the trial. They will be randomized to start buprenorphine with either standard initiation or with a new approach called rapid outpatient low-dose initiation (ROLDI). For standard initiation, participants will be instructed to arrive to the unit with at least 8 hours since last fentanyl use. Once they have at least moderately severe opioid withdrawal (Clinical Opiate Withdrawal Scale \[COWS\] 11 or higher), participants will receive 2 mg, 2 mg, 4 mg, and then 8 mg sublingual buprenorphine, with doses every 2 hours. They will then continue 8 mg twice daily (or up to three times daily). This is the current standard of care. For ROLDI, participants will not be required to have a period abstinence, they will have no or minimal withdrawal (COWS 4 or less) when starting buprenorphine, and participants will take 0.5 mg, 0.5 mg, 1 mg, 1 mg, 1 mg, and then 4 mg sublingual buprenorphine with dosing every two hours. They will then continue 8mg twice daily (or up to three times daily). The main aim of this clinical trial is to assess whether ROLDI is safe, feasible, acceptable to patients, and worthwhile to study in a larger trial. The secondary aim is to describe fentanyl and norfentanyl pharmacokinetics (that is to say, fentanyl and norfentanyl concentration in blood and urine) during early abstinence to understand why some people using fentanyl develop precipitated withdrawal with standard initiation.
The opioid overdose epidemic has persisted for several decades and is now further complicated by the permeation of fentanyl into the illicit opioid supply. While the effectiveness of medications to treat opioid use disorder (MOUD) have been well documented in the literature, the addition of fentanyl to the drug supply has complicated the initiation of MOUD, especially buprenorphine. Naloxone, an opioid antagonist, is currently utilized to reverse opioid overdose by displacing less-competitive ligands which bind at the mu-opioid receptor. Because induction to buprenorphine in the age of fentanyl is uncomfortable and can take several days to stabilize a patient on a therapeutic dose, the use of naloxone prior to buprenorphine can aid in a safe and rapid transition to buprenorphine treatment, without the effect of unintended prolonged precipitated withdrawal which can occur following the displacement of fentanyl by buprenorphine on the mu-opioid receptor. Therefore, this project will assess feasibility and acceptability of naloxone-facilitated buprenorphine initiation using a single-ascending dose design. The investigators will examine whether a single dose of buprenorphine is tolerated following administration of naloxone among a small group of individuals. If the dose is tolerated, the investigators will administer a larger dose among another small group of individuals. The investigators will examine the tolerability of up to 4 doses of buprenorphine following naloxone. This buprenorphine induction method has been characterized in case studies but it has not been evaluated in an empirical, systematic way in a controlled setting. This study will take place within an residential facility at Johns Hopkins Bayview Medical Campus, and will have immediate, real-world applicability in establishing a rapid, safe, and effective option to transition people with chronic fentanyl use to buprenorphine treatment.
The goal is to determine whether fentanyl and morphine have similar effects in reducing aspirin's effect upon platelets in emergency department patients with chest discomfort. Morphine has been shown to worsen outcomes in heart attack patients due to reduction of oral anti-platelet agent effectiveness and so many providers have switches to using fentanyl. However, it is largely unknown whether fentanyl has similar effects.
This is a 4-week, randomized-controlled trial of suvorexant vs placebo in persons with opioid use disorder who have recent fentanyl exposure. Participants will first undergo a 5-day residential phase wherein participants are stabilized on sublingual buprenorphine/naloxone, followed by a 3-week outpatient phase wherein participants are maintained on sublingual buprenorphine/naloxone and transitioned to extended-release buprenorphine).
Fentanyl is the most commonly used opioid during anesthesia at Massachusetts General Hospital. Compared to other opioids, e.g. sulfentanil and remifentanil, fentanyl's pharmacokinetic properties are more problematic as the context sensitive half-time increases with duration of fentanyl infusion. This may lead to respiratory complications particularly in patients who receive fentanyl for surgical procedures of long duration. Considering the common use of fentanyl during surgery and its duration of action that is hard to predict during long surgical procedures, we will evaluate the association between intraoperative fentanyl dose and postoperative respiratory complications within 3 days of surgery.
The purpose of this study is to determine if methadone improves postoperative pain control in pediatric patient's undergoing cardiac surgery.
With potent analgesic properties, perceived hemodynamic benefits and limited alternatives, opiates are the analgesic mainstay for acute coronary syndrome (ACS) patients reporting peri-procedural pain or nitrate-resistant chest pain. However, large observational studies suggest that opiate administration during ACS may result in adverse cardiovascular outcomes. Complimenting this, a number of recent mechanistic studies have demonstrated delayed and attenuated effects of oral dual anti-platelet therapy (DAPT) on platelet inhibition endpoints among subjects receiving intravenous morphine. These studies support the hypothesis that morphine delays the gastrointestinal absorption of DAPT medications. However, no data exist on the impact of intravenous fentanyl, a systemic opioid analgesic routinely administered during percutaneous coronary intervention (PCI) procedures, on the platelet inhibition effects of DAPT. The investigators hypothesize that, similar to morphine, fentanyl administered at the time of PCI will reduce and delay the effect of DAPT on platelet function. As such, the primary aim of this study is to test the impact of intravenous fentanyl on residual platelet reactivity by randomizing patients undergoing PCI to a strategy of peri-procedural benzodiazepine plus non-systemic local analgesia or to the current standard of benzodiazepine plus intravenous fentanyl. Given the critical need for rapid and robust inhibition of platelet function during PCI, this trial has true potential to change clinical practice, particularly if the investigators demonstrate reduced DAPT absorption and elevated residual platelet reactivity among patients receiving fentanyl during PCI.
The purpose of this study is to evaluate the cumulative adhesion percentage for the test products and the reference products for both small and large patches.
Hypotension is frequently encountered after induction of general anesthesia. It can be pronounced in elderly patients and can require administration of vasopressor agents including ephedrine and phenylephrine. Intraoperative hypotension, especially prolonged episodes, can contribute to an increase in morbidity and mortality in the postoperative period as suggested by some former studies. The investigators hypothesize that fentanyl can contribute to the decrease in blood pressure (BP) that is seen after induction of general anesthesia in older patients. This hypotension may be due to fentanyl blocking effect on the sympathetic nervous system. This study will be the first one to examine the effect of fentanyl administration on blood pressure in elderly patients with induction of general anesthesia prior to the start of surgery. If the study shows that fentanyl contributes to hypotension during this period, it may lead to a change in practice and better patient outcomes and mortality rates.
Epidural analgesia has proven to be an effective method for severe pain relief associated with labor and delivery. During labor, a low dose continuous infusion of local anesthetic and narcotic will be administered through an epidural catheter. As labor progresses and the baby's head makes it way through the pelvis, breakthrough pain may emerge and often needs further treatment. The investigators provide pain relief by administering analgesics through the epidural catheter. The patients will be randomly assigned to receive one of two medication mixtures believed to be successful in treating this type of pain associated with advanced labor. After this initial treatment, if pain relief is not attained, the patient may receive the other medication as well. The medications used in this study have been used at this institution for some time and have been found to be safe for mother and baby. The opioid (fentanyl) dose is small and only a small fraction will be transmitted to the baby. The other medication (clonidine) better known as a blood pressure medication has also been used for pain relief. Studies and clinical experience have shown that clonidine when given epidurally in the doses used in this study has minimal, if any effect, on the blood pressure of the mother or of the baby. The investigators will record medical and obstetric history and labor progress relevant to the patient. The patient will be asked questions regarding labor pain and side effects before and after the analgesic is administered. The primary objective is to determine which treatment regimen is more successful in abolishing breakthrough pain in advanced labor.
Procedures performed under sedation have the same severity in regards to morbidity and mortality as procedures performed under general anesthesia1. The demand for anesthesia care outside the operating room has increased tremendously and it poses, according to a closed claim analysis, major risks to patients. Both closed claim analysis identified respiratory depression due to over sedation as the main risk to patients undergoing procedures under sedation. The major problem is that hypoventilation is only detected at very late stages in patients receiving supplemental oxygen. Besides the respiratory effects of hypoventilation, hypercapnia can also lead to hypertension, tachycardia, cardiac arrhythmias and seizures. The incidence of anesthetized patients with obstructive sleep apnea has increased substantially over the last years along with the current national obesity epidemic. These patients are at increased risk of hypoventilation when exposed to anesthetic drugs. The context of the massive increase in procedural sedation and the extremely high prevalence of obstructive sleep apnea poses major respiratory risks to patients and it may, in a near future, increase malpractice claims to anesthesiologists. The development of safer anesthesia regimen for sedation are, therefore, needed. The establishment of safer anesthetics regimen for sedation is in direct relationship with the anesthesia patient safety foundation priorities. It addresses peri-anesthetic safety problems for healthy patient's. It can also be broadly applicable and easily implemented into daily clinical care. Ketamine has an established effect on analgesia but the effects of ketamine on ventilation have not been clearly defined. The investigators have demonstrated that the transcutaneous carbon dioxide monitor is accurate in detecting hypoventilation in patients undergoing deep sedation. Animal data suggest that when added to propofol in a sedation regimen, ketamine decreased hypoventilation when compared to propofol alone. It is unknown if ketamine added to a commonly used sedative agent (propofol) and fentanyl can decrease the incidence and severity of hypoventilation in patients undergoing deep sedation. The investigators hypothesize that patients receiving ketamine, propofol and fentanyl will develop less intraoperative hypoventilation than patients receiving propofol and fentanyl. The investigators also hypothesize that this effect will be even greater in patients with obstructive sleep apnea than patients without obstructive sleep apnea. Significance: Respiratory depression due to over sedation was identified twice as the major factor responsible for claims related to anesthesia. The high prevalence of obstructive sleep apnea combined with more complex procedures done in outpatient settings can increase physical risks to patients and liability cases to anesthesiologists. The main goal of this project is to establish the effect of ketamine in preventing respiratory depression to patients undergoing procedures under deep sedation using propofol and fentanyl. If the investigators can confirm our hypothesis, our findings can be valuable not only to anesthesiologist but also to other specialties (emergency medicine, gastroenterologists, cardiologists, radiologists) that frequently performed procedural sedation. The research questions is; does the addition of ketamine prevent hypoventilation during deep sedation using propofol and fentanyl? The hypotheses of this study: Ketamine will prevent hypoventilation during deep sedation cases.
The goal of this clinical research study is to learn if fentanyl given under the skin can reduce shortness of breath in cancer patients. Researchers also want to learn if it can help to improve your physical function. In this study, fentanyl will be compared to a placebo. Fentanyl is commonly used for treatment of cancer pain. It is believed to help patients with their shortness of breath as well. A placebo is not a drug. It looks like the study drug but is not designed to treat any disease or illness. It is designed to be compared with a study drug to learn if the study drug has any real effect.
Intrapartum epidural analgesia has been associated with adverse breastfeeding outcomes. One potential mechanism involves transfer of epidural fentanyl across the placenta and neonatal blood-brain barrier, where it can subsequently attenuate neonatal exhibition of feeding behaviors, such as latching and swallowing, during the immediate postpartum period. Vigorous feeding behavior during the first days of life is a significant predictor of long-term breastfeeding success at 3 and 6 months. In a randomized, controlled, double-blinded study, neonatal Neurologic and Adaptive Capacity Scores (NACS) were significantly lower when mothers received \>150 mcg epidural fentanyl versus bupivacaine-only analgesia, and mean umbilical cord fentanyl concentration was significantly higher in the \>150 mcg versus \<150 mcg group. The investigators hypothesize that epidural fentanyl-bupivacaine analgesia is significantly associated with decreased breastfeeding rates at hospital discharge and with neonatal deficits in latching onto the breast and swallowing during the first three hours of life, and that a significant dose-response relationship exists with respect to total micrograms fentanyl infused. The investigators will perform a prospective cohort study of all parturients age 18+ at UHCMC over a three-month period, excluding those with multiples gestation, Cesarean section, or neonatal intensive care unit admission. From patient charts, the investigators will record the following variables: number of neonates delivered; type of delivery (spontaneous vaginal / operative vaginal / Cesarean section); whether the neonate was admitted to the intensive care unit; the mother's age, height, weight, gravity, parity, intention to breast-feed at the time of hospital admission, number of children previously breast-fed, and ethnicity; gestational age at the time of delivery; administration of oxytocin for labor augmentation and in what quantity; duration of active labor; antibiotic administration; neonatal APGAR scores at 1 and 5 minutes postpartum; and whether opioids or antibiotics were administered before and/or after the delivery and at what exact time. We will also record whether each patient received an epidural during labor and, if so, the duration of this epidural infusion and the total micrograms fentanyl delivered; neonatal feeding behavior as quantified by the LATCH scores assigned to each breast-feeding interaction that occurs on the postpartum care floor; whether the mother is breast-feeding her baby at the time of discharge from the hospital, and if not, then her primary reason for not doing so (as communicated during the standard postpartum lactation consultation); and how long mother and baby stayed in the hospital post-delivery.
The purpose of this study is to determine if intranasal fentanyl can decrease the pain of patients with sickle cell disease who present to the pediatric emergency department with a vaso-occlusive crisis.
The purpose of this research is to evaluate the effectiveness of fentanyl for reducing coughing during the perioperative period (i.e., insertion of an LMA \[Laryngeal Mask Airway\] device, maintenance period during surgery, and awakening \[emergence\] from general anesthesia) for ambulatory surgery procedures. Also to assess the effects of fentanyl on the postoperative outcomes, (e.g., pain, postoperative nausea and vomiting, return of bowel function \[constipation\], resumption of normal activities of daily living). Fentanyl is one of the most common used anesthetic adjuncts for ambulatory surgery because of its anesthetic-sparing effects and alleged ability to reduce coughing during instrumentation of the patient's airway.
The purpose of this study was to evaluate the oral bioequivalence of the Mallinckrodt test fentanyl citrate oral transmucosal 400 mcg troche compared to Actiq 400 mcg (Cephalon, Inc.) under fasting conditions.
Epidurally administered Depodur provides equal or superior analgesia as an epidural infusion of fentanyl for the first 48 hours after a cesarean section.
Epidural analgesia is widely regarding as the most effective analgesic strategy for labor pain. Modern practice is to utilize dilute local anesthetics as a continuous infusion along with an opioid, e.g., our common "recipe" of 12 ml/hr of 0.0625% bupivacaine with 2 micrograms/ml fentanyl, after the initial dose to maintain patient comfort until delivery. This dose of the infusion often provides adequate comfort without interfering with the mobility of the patient and her ability to effectively push during delivery. However, this low dose epidural infusion strategy often results in recurrence of pain after an initial pain free period. This breakthrough pain is treated by administering small boluses of analgesics via the epidural catheter. The pain occurring in labor is initially of visceral origin and is mediated by pain fibers originating from the low thoracic and upper lumbar segments of the spinal cord. As labor progresses to the late first phase (also known as transitional stage), pain sensations originating from the distension of the pelvic floor, vagina and perineum adds a somatic component to labor pain. This type of breakthrough pain is often difficult to treat. Although requests from patients to alleviate late stage breakthrough pain are common, no one knows the most effective strategy for pain management in this stage of labor. This study is designed to compare the efficacy of two treatments for controlling late first stage breakthrough pain during labor with an epidural infusion in place: clonidine-bupivacaine versus fentanyl-bupivacaine. Women who have labor epidural analgesia in place will be enrolled to be randomized if and when they present with breakthrough pain in the late first stage or second stage of labor (≥ 8 cm dilated). They will receive 8 ml of a solution containing 10 mg bupivacaine and 75 micrograms of either fentanyl (an opioid or "narcotic") or clonidine (an "alpha-2 agonist known to be effective as an epidural analgesic). Pain relief, labor progress and outcome will be assessed to compare fentanyl versus clonidine. It is the hypothesis of this study that clonidine added to bupivacaine is a better analgesic than fentanyl added to bupivacaine for breakthrough pain in advanced labor.
The study is exempt from informed consent by the MetroHealth Medical Center institutional review board (IRB), because two standards of care are used and there is no increased clinical risk to the patient due to the study. The researchers randomize either fentanyl or morphine to be given to trauma patients and record how their pain scale is treated along with observing for adverse events. They are looking to see if the hypothesized benefits of fentanyl (which is much more expensive than morphine) actually exist.
Background: A Timeline Follow-Back (TLFB) is a tool that helps researchers track how much of a substance a person uses. Different versions of the tool are used to track the use of alcohol, cigarettes, and cannabis. But there is no TLFB to track a person s use of nonmedical opioids. (These are opioids not obtained from a medical source; they may also be called "street" opioids.) Researchers are creating an Opioid TLFB (OpiTLFB) that asks better questions and records more useful answers to identify what kinds of nonmedical opioids people are using. Objective: To test a new research tool to track a person's use of nonmedical opioids. Eligibility: People aged 18 years or older who used a nonmedical opioid within the past 30 days. Design: Participants will have 1 study visit at a clinic in Baltimore, Maryland. The visit will take 1 to 4 hours. Participants will sit at a computer with a researcher and fill out a calendar. They will record their use of opioids each day for the past 30 days. They will be asked what the drugs were called and what they looked like. This task might take 30 minutes. Participants will be interviewed. The researcher will ask about their experiences getting opioids from friends, dealers, or other sources; how the experience of getting opioids has changed over time; and about any changes they have noticed across different areas of Baltimore. Researchers will ask how the OpiTLFB could be easier to fill out and how it could provide more useful information. This task might take 30 minutes. Participants will provide a urine sample.
In situations where intravenous access is not readily available or is unobtainable and the intranasal route is not feasible, another non-invasive route of ketamine administration, such as inhalation via breath-actuated Nebulizer (BAN), is becoming a viable alternative. The BAN allows the controlled, patient-initiated delivery of analgesics in a measured and titratable fashion. (18) Ketamine has been studied as a nebulized drug in a lot of different settings and for a lot of different reasons, such as to treat acute pain after surgery (like a sore throat after being intubated), as a pre-medication for general anesthesia, to treat cancer pain, and as a therapy for asthmaticus. Our research team has published two case series of 10 adult patients who were given nebulized ketamine (via BAN) for a variety of acute traumatic and non-traumatic painful conditions. The patients showed a 60% decrease in pain and a small number of side effects. Furthermore, our group published a randomized, double-blind trial of 120 adult patients evaluating the analgesic efficacy and safety of nebulized ketamine at three different dosing regimens for acute pain in the ED (0.75 mg/kg, 1 mg/kg, and 1.5 mg/kg), showing similar analgesic efficacy between the three different dosing regimens for short-term (up to 120 minutes) pain relief. Lastly, we recently completed a randomized, double-blind, double-dummy clinical trial comparing the analgesic efficacy and safety of nebulized ketamine and intravenous ketamine in managing acute pain in adult ED patients, with data currently being analyzed. Nebulized fentanyl given in the ED to adults with acute traumatic and non-traumatic pain syndromes at a dose range of 1.5-4 mcg/kg showed the same or even better pain-relieving effects than IV fentanyl and IV morphine alone. Our objective is to compare the analgesic efficacy and rates of side effects of a 0.75 mg/kg dose of ketamine administered via breath-actuated nebulizer (BAN) to a dose of 3 mcg/kg of fentanyl administered via breath-actuated nebulizer (BAN) in adult patients presenting to the ED with acute painful conditions.
The purpose of this randomized controlled trial is to compare the effectiveness of epidural clonidine, dexmedetomidine, or fentanyl adjuncts for labor analgesia.
The hypothesis is that intranasal dexmedetomidine will provide significantly more effective analgesia and anxiolysis for subjects undergoing a simple laceration repair when compared to either intranasal fentanyl or intranasal midazolam. Additional hypotheses include that there will be 1) no significant increase in adverse effects between drugs and 2) significantly higher satisfaction rates for both subject experience and ease of laceration repair based on structured, proceduralist feedback.
Ketamine is commonly used for procedural sedation and analgesia. It is widely used for trauma cases in the emergency department and is considered a superior agent in the outpatient setting due to its lack of respiratory and cardiovascular depression. In chronic opioid users, ketamine decreases acute pain and reduces postoperative opioid consumption. Few studies have examined the use of ketamine for surgical abortions. Previous studies found significant rates of emergence phenomena; however, this can be prevented if a benzodiazepine is given at the same time. Ketamine deserves further study to determine whether it is an acceptable alternative to a standard opioid-based regimen for surgical abortion. Our primary objective is to compare patient satisfaction after surgical abortion among patients receiving IV ketamine versus IV fentanyl for procedural sedation. Our secondary objectives include postoperative pain, additional pain medication used, and postoperative opioid use after the procedure. Our hypothesis is that ketamine will provide similar patient satisfaction and reduce postoperative opioid use. This will be a randomized controlled noninferiority clinical trial of 84 women receiving either IV ketamine with IV midazolam or IV fentanyl with IV midazolam for outpatient one day surgical abortions up to 13, 6/7 weeks gestation. Both groups will receive a standardized paracervical block and additional pain medication as needed. Our study has the potential to introduce IV ketamine as a satisfactory medication for outpatient surgical abortions. Ketamine may decrease the need for IV fentanyl, reduce postoperative opioid use, and may prove to be a superior analgesic for chronic opioid users.
The overall goal of this pilot study is to characterize illicit fentanyl and combination fentanyl and opioid dependence explicitly, by assessing physiologic barriers to effective buprenorphine induction. Results from this pilot study may make a case for a larger feasibility study to be conducted through the Clinical Trials Network at the National Institutes of Drug Abuse. The primary hypothesis is that individuals dependent on illicit fentanyl and combination fentanyl and opioids will have difficulty with standard buprenorphine induction, and will need a modified approach. The primary outcome measure will be retention on buprenorphine at seven days post induction. The secondary outcome measures will be objective precipitated withdrawal and the rate of patients requiring or requesting to initiate methadone due to intolerance of buprenorphine.
A RCT to compare hydromorphone versus fentanyl for pain control following tonsillectomy or adenotonsillectomy surgery.
This phase II trial studies fentanyl buccal tablet or morphine to see how well it works compared to a placebo in controlling shortness of breath during or after physical activity in cancer patients. Fentanyl sublingual tablet and morphine are opioids normally used to control pain that may also help to prevent or control shortness of breath during or after physical activity in cancer patients.
The purpose of this study is to determine if a single dose of sublingual sufentanil is as or more efficacious than a single dose of IV fentanyl in a post anesthesia care setting.
