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.
Allocation: Randomized, Control: Active Control, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Prevention

The purpose of this study is to compare propofol associated with fentanyl versus midazolam plus fentanyl for sedation during diagnosis or therapeutic upper gastrointestinal endoscopy (UGE)...
OBJECTIVES: I. Assess the degree of amnesia afforded by study sedatives relative to the patient's intensive care unit experiences. II. Evaluate the efficacy and safety of propofo...
The aim of this study is to increase knowledge about drug properties and effects during therapeutic hypothermia. The primary end point of this study is the time from termination of sedatio...
Endoscopic submucosal dissection is commonly performed under light to moderate sedation, and minimizing patient movement is of key importance for successful outcome. Propofol has widely re...
This is a randomized controlled trial to compare propofol to dexmedetomidine for prolonged sedation (> 24 hours) in critically ill patients who require mechanical ventilation.
Sevoflurane is associated with a relatively high incidence of emergence agitation (EA) in children. Prophylactic treatment, including midazolam, dexmedetomidine, ketamine, fentanyl and propofol, has b...
Fentanyl is primarily metabolized by CYP3A, but has also been suggested to act as a weak inhibitor of CYP3A. We investigated the influence of CYP3A inhibition by ketoconazole on the pharmacokinetics o...
Previous studies on the antioxidant activity of sedatives have predominantly been in vitro investigations that are lacking clinical data, resulting in conclusion without cogency. The aim of the presen...
Hemodynamic Responses to Two Different Anesthesia Regimens in Compromised Left Ventricular Function Patients Undergoing Coronary Artery Bypass Graft Surgery: Etomidate-Midazolam Versus Propofol-Ketamine.
Various methods have been suggested to prevent hemodynamic instability caused by propofol and adverse effects caused by etomidate induction. The current study evaluated hemodynamic effects of propofol...
Sedatives can impair the swallowing process. We assessed the incidence and severity of swallowing impairment in patients sedated with propofol at clinically relevant doses. We also identified factors ...
An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.
A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)
A condition of low alertness or cognitive impairment, usually associated with prolonged mental activities or stress.
Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.
A childhood disorder predominately affecting boys and similar to autism (AUTISTIC DISORDER). It is characterized by severe, sustained, clinically significant impairment of social interaction, and restricted repetitive and stereotyped patterns of behavior. In contrast to autism, there are no clinically significant delays in language or cognitive development. (From DSM-IV)
