| NCT00336882 ↗ | Anaesthesia With Propofol Versus Midazolam : Effect on Oxidative Stress in the Brain of Head Trauma Patients | Terminated | Ministry of Health, France | Phase 3 | 2006-06-01 | Severe traumatic brain injury is associated with an increased production of free radicals causing brain damage. First line treatment of these patients aims to maintain cerebral perfusion and includes deep anaesthesia. Propofol has recently shown anti oxidant properties that need to be confirmed when used in these patients. The main objective of this study is to evaluate the effect of propofol compared to midazolam on intra cerebral oxidative stress following severe traumatic brain injury. |

| NCT00390871 ↗ | Acute Neurological ICU Sedation Trial (ANIST) | Completed | Daniel Hanley | Phase 2 | 2005-05-01 | Dexmedetomidine (Precedex, Hospira) is a "super" selective alpha2-agonist - 8-10x more avid binding to alpha2 receptors than clonidine - and may have particularly favorable characteristics as a continuous i.v. infusion sedative for critically ill neuroscience patients. Its combination of anxiolysis, analgesia, without undue lethargy may make it an ideal agent where frequent neurological examinations are important. Unclear, however, is whether Precedex is superior to current common i.v. sedation protocols, and if there are any undue concerns of this agent on cerebral physiology and cortical stimulation. |

| NCT00395681 ↗ | Population PK/PD of Propofol in the Morbidly Obese Patient | Completed | St. Antonius Hospital | Phase 4 | 2007-09-01 | Rationale: The extreme increase of obesity in the last years had led to this study. There is no consensus about how to anaesthetise morbidly obese patients. The amounts of narcotics given vary widely and rather depend on the anaesthetist than on the pharmacokinetics and dynamics in the morbidly obese patient. Reason for this is that it is not clear in what extend the pharmacokinetics and dynamics are affected in the morbidly obese patient. Objective: The study is performed in order to develop a population pharmacokinetic and pharmacodynamic model of Propofol when used for induction and maintenance of anaesthesia in the morbidly obese patient (BMI > 40). A covariate analysis will be performed in order to account for variability in pharmacokinetic and/or pharmacodynamic parameters. This model will take into account patient and procedure bound covariates. The results will be used to develop individualised dosing schemes of Propofol when used for induction and maintenance of anaesthesia in morbidly obese patients. Study design: A randomised, therapeutic and non-invasive study. Study population: Morbidly obese patients with a Body Mass Index > 40 undergoing laparoscopic banding or gastric bypass surgery, 18-60 year old. Intervention (if applicable): Patients will be randomised into two groups, one group will be given 200 milligrams of Propofol and the other group will be given 350 milligrams of Propofol. During the induction of anaesthesia with Propofol over 60 seconds, the patient is asked to count in order to measure time to induction of anaesthesia. During and following anaesthesia a maximum of 50 ml of blood will be taken from an indwelling arterial line. Depth of sedation will be measured using non-invasive Bispectral Index (target 40-60) and other standard measures (heart frequency and blood pressure). Main study parameters/endpoints: Primary endpoints: pharmacokinetic parameters; clearance, intercompartmental clearance, volume of central compartment and volume of peripheral compartment. Secondary endpoints: pharmacodynamic parameters; time to induction of anaesthesia (stop counting, eyelash reflex, quality of anaesthesia, corresponding dose required for induction of anaesthesia for both induction doses), EC50 using BIS, required doses of Propofol during maintenance of anaesthesia, wake-up time. Nature and extent of the burden and risks associated with participation benefit and group relatedness: A maximum amount of 50 milliliters of blood will be sampled from an indwelling arterial line. The patient will be asked to count slowly during induction of anaesthesia. Both induction doses of 200 and 350 milligrams are currently used standard induction doses for morbidly obese patients. |
| NCT00446420 ↗ | Cognitive Impairment Following Sedation for Colonoscopy With Propofol, Midazolam and Fentanyl Combinations | Completed | Melbourne Health | Phase 4 | 2007-02-01 | Our hypothesis is that adding midazolam and/or fentanyl to propofol sedation for elective outpatient colonoscopy increases cognitive impairment at hospital discharge without improving intraoperative conditions or reducing intraoperative side-effects. 200 healthy patients aged 18 years or older will be randomised to receive propofol or propofol plus midazolam and/or fentanyl. Cognitive impairment will be tested at hospital discharge using Cogstate computerised testing software. |
| NCT00538616 ↗ | Precedex Versus Propofol-Awakening for Reducing Brain Injury Expansion | Completed | Hospira, Inc. | Phase 1/Phase 2 | 2008-01-01 | The purpose of this study is to evaluate brain injury when two different drugs (propofol and precedex) are used to sedate patients who need a neurologic exam. |
