NCT ID: NCT06462196 Not yet recruiting - Clinical trials for Major Depressive Disorder

Natural History of Depression, Bipolar Disorder and Suicide Risk

Start date: June 26, 2024
Phase:
Study type: Observational

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation....

NCT ID: NCT06431178 Recruiting - General Anesthesia Clinical Trials

General Anesthesia Versus Sedation By Dexmedetomidine and Ketamine With Local Infiltration for Percutaneous Transcatheter Closure of Atrial Septal Defect in Pediatric Patients

Start date: May 1, 2024
Phase: N/A
Study type: Interventional

The aim of the present study is to compare between general anesthesia versus sedation with dexmedetomidine and ketamine with local infilteration at the catheter insertion site in pediatric patients undergoing transcutaneous closure of atrial septal defect on hemodynamic changes.

NCT ID: NCT06412861 Recruiting - Sedation Clinical Trials

Propofol-ketamine or Propofol-fentanyl for Procedural Sedation in the Short-term Gynecological Case

Start date: April 20, 2024
Phase: N/A
Study type: Interventional

Comparison of fentanyl-propofol and ketamine-propofol combination for sedation in brief gynecological cases Our study aimed to evaluate ketamine-propofol and fentanyl-propofol combinations in short-term gynecological cases in terms of hemodynamic parameters, recovery, complications, patient and physician comfort.

NCT ID: NCT06344858 Recruiting - Analgesia Clinical Trials

Characterization of the Temporal Profile of the Anti-nociceptive Effect of Ketamine Bolus Measured With ANI

Keta-ANI
Start date: April 30, 2024
Phase:
Study type: Observational [Patient Registry]

Ketamine, an intravenous anesthetic, and analgesic agent has experienced a resurgence in its clinical application, particularly in subanesthetic doses. The aim of this observational study is to characterize the changes in the Nociception Analgesia Index (ANI) associated with the administration of an intravenous ketamine bolus using a Pharmacokinetic-Pharmacodynamic (PKPD) modeling approach. The pharmacokinetic parameters of the Domino model will be used to predict ketamine plasma concentrations after the bolus dose. An Emax model and a link model assuming a first order rate constant (ke0) will be used to fit the data. Modeling analysis will use the program NONMEM. It is expected to recruit a total of 20 patients between 40 and 80 years, ASA I, II or III, programmed for elective surgery with general anesthesia. ANI values will be recorded every 6 seconds for 5 minutes from the bolus dose.

NCT ID: NCT06331182 Recruiting - Dexmedetomidine Clinical Trials

Dexmedetomidine and Ketamine as an Adjuvant in External Oblique Intercostal Plane Block for Post Thoracotomy Pain

Start date: March 26, 2024
Phase: N/A
Study type: Interventional

The aim of this study is to compare the role of dexmedetomidine and ketamine as an adjuvant in external oblique intercostal plane block for post thoracotomy pain.

NCT ID: NCT06243822 Completed - Clinical trials for Mechanical Ventilation

Ketamine Versus Propofol as ICU Sedation

Start date: October 1, 2022
Phase: Phase 4
Study type: Interventional

this study is to assess the hemodynamic profile of ketamine compared with propofol in critically ill, mechanically ventilated adult Patients study will be carried out on 100 mechanically ventilated patients who received one sedative agent propofol or ketamine The patients will be randomized into two equal groups to receive either ketamine or propofol Group 1 (Ketamine group): ketamine is initiated at 0.5 mg/kg/h and titrated by 0.25 mg/kg/h every 15 minutes to a maximum dosage of 4 mg/kg/h to achieve appropriate sedation. Group 2 (Propofol group): Propofol is initiated at 0.3 to 0.6 mg /kg/hr. and titrated by 0.3 to 0.6 mg/kg/h every 5 to 10 minutes up to a maximum dosage of 4.5 to 4.8 mg/kg/hr. to achieve appropriate sedation.

NCT ID: NCT06181188 Completed - Clinical trials for Patient Satisfaction

Use of Ketamine for Conscious Sedation in Flexible Bronchoscopy

Start date: July 15, 2019
Phase: Phase 4
Study type: Interventional

In this study, the investigators plan to conduct a single blinded randomized controlled trial in the Pulmonary Service to demonstrate the efficacy of ketamine and its utility in moderate sedation. Patients presenting for bronchoscopy who meet inclusion criteria will be approached, and if amenable, will be consented and enrolled. Patients will be randomized to receive either 1 mg of midazolam and ketamine 0.25 to 0.5 mg/kg loading dose with subsequent doses of 10-20 mg IV or standard fentanyl and midazolam in 25mcg and 1mg increments respectively for moderate sedation during their procedure. The primary outcome will be patient satisfaction, which will be measured a using patient clinical satisfaction form. A number of secondary outcomes will include the following: (1) provider satisfaction (2) the time from sedation administration to procedure start (when the scope is inserted), (3) the time from sedation to scope removal from the trachea (4) the time from sedation to discharge (defined as the time from the end of the procedure until the patient meets discharge criteria from the recovery area), (5) total dose of medications given (including midazolam, fentanyl, and ketamine), (6) adverse events, (7) vital signs, (8) and the need for additional medications, in particular reversal agents.

NCT ID: NCT06021717 Completed - Ketamine Clinical Trials

PCA Ketamine-Morphine VS PCA Morphine as Post-Operative Analgesia in Colorectal Surgery

Start date: April 5, 2018
Phase: Phase 4
Study type: Interventional

The goal of this clinical trial is to compare the effectiveness of PCA ketamine-morphine versus conventional PCA morphine in postoperative patients undergoing elective laparotomy colorectal surgery under general anaesthesia. The specific objectives are: 1. To compare the post-operative analgesic requirement with PCA ketamine-morphine in comparison with PCA morphine. 2. To compare the postoperative pain scores between PCA ketamine-morphine and PCA morphine. 3. To assess patients' overall satisfaction with PCA ketamine-morphine in comparison with PCA morphine. 4. To study the incidence of side effects of PCA ketamine-morphine in comparison with PCA morphine. Participants will be screened and recruited at pre-anaesthetic clinic (PAC). Those who consented will be taught to use PCA machine and the potential side effects of the study drugs. They will be randomly allocated into either Group A or Group B by computer generated randomization a day before planned surgery. Researchers will compare Group A and Group B to see post-operative pain scores, patients' overall satisfaction and any incidence of side effects.
