BACKGROUND AND OBJECTIVES Sedation-analgesia is recommended for comfortable colonoscopy procedures, which are invasive and can be painful. This study aimed to compare the combinations of propofol-alfentanil and propofol-fentanyl for sedation-analgesia in elective colonoscopy patients. METHODS This prospective and randomized study was planned in ASA I-II groups and included 80 patients between...

Propofol (2,6-diisopropylphenol) is a widely-used anesthetic agent attributable to its rapid biotransformation. Liver microsomal cytochrome P450 (P450) isoforms involved in the biotransformation of propofol in rats and the effects of propofol in vivo on P450 levels in rats were investigated. Of six cDNA-expressed rat P450 isoforms tested, CYP2B1 and CYP2C11 had high catalytic activities from 5 ...

Study Design: Randomized Controlled Trial Setting: National Hospital Medical Centre, Lahore Sampling Technique: Consecutive non-probability sampling duration: 06-02-18 to 06-08-18 Methodology: The cases with age range 16 60 years either gender ASA st...

BACKGROUND Oxidative stress occurs during the aging process and other conditions such as bone fracture, bone diseases, and osteoporosis, but the role of oxidative stress in bone remodeling is unknown. Propofol exerts antioxidant effects, but the mechanisms of propofol preconditioning on oxidative stress have not been fully explained. Therefore, the aim of this study was to evaluate the protecti...

BACKGROUND AND AIMS Propofol (2,6-diisopropylphenol), one of the most commonly used intravenous anaesthetic agents during cancer resection surgery, has been reported to have the ability of influencing the invasion of human cancer cells. However, the mechanisms are not very clear. In this study, we investigated the effects of propofol on the proliferation, invasion and angiogenesis of human Eca-...

Colonoscopy is typically performed with sedation. Intravenous benzodiazepines with or without opioids have long been used to induce sedation for both colonoscopy and more complex endoscopic procedures. In recent years, we have observed a rapid transformation from the use of opioids and benzodiazepines to sedation with propofol in Western countries.1 However, most endoscopy centers in the Middle...

BACKGROUND Microglial activation is implicated in delayed tissue damage after traumatic brain injury (TBI). Activation of microglia causes up-regulation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, with the release of reactive oxygen species and cytotoxicity. Propofol appears to have antiinflammatory actions. The authors evaluated the neuroprotective effects of propofol after...
