BACKGROUND AND OBJECTIVES Clonidine and dexmedetomidine are alpha2-adrenergic agonists with analgesic proprieties which potentiate local anesthetic effects when epidurally administered. The goal of this study was to evaluate the analgesia and sedation promoted by clonidine or dexmedetomidine associated to epidural ropivacaine, in the postoperative period of subcostal cholecystectomy. METHODS ...

BACKGROUND We explored the sympatholytic property of dexmedetomidine, especially its role in intraocular pressure (IOP) reduction, haemodynamic stability, and attenuation of extubation response. METHOD In this double-blind, randomized, controlled trial approved by the Hospital Ethics Committee, 60 patients undergoing elective vitreoretinal surgery were allocated to two groups, receiving eithe...

OBJECTIVES To systematically review the literature comparing the efficacy and safety of dexmedetomidine and midazolam when used for procedural sedation. MATERIALS AND METHODS We searched MEDLINE, EMBASE and COCHRANE for clinical trials comparing dexmedetomidine and midazolam for procedural sedation up to June 20, 2016. Inclusion criteria: clinical trial, human subjects, adult subjects (≥18 ye...

OBJECTIVE We compared the effects of 2 sedative drugs, dexmedetomidine and midazolam, on motor performance and analgesic efficacy in a rat model. MATERIALS AND METHODS Rats were randomly divided into the following 4 groups on the basis of the treatment received. The first group received 83 µg/kg/min midazolam; the second, 1 µg/kg/min dexmedetomidine; the third, 83 µg/kg/min morphine; and the ...

Dexmedetomidine is an α-2 agonist that produces sedation and analgesia without compromising the respiratory drive. Use of dexmedetomidine as a sedative in the critically ill is associated with fewer opioid requirements compared with propofol and a similar time at goal sedation compared with benzodiazepines. Dexmedetomidine may produce negative hemodynamic effects including lower mean heart rate...

Objective To evaluate the efficacy and safety of spinal anaesthesia using dexmedetomidine for caesarean section. Methods PubMed, The Cochrane Library, and CNKI were searched for relevant literature. Results The incidence of nausea and vomiting in the dexmedetomidine group was significantly lower than that in the control group (OR = 0.21, 95% CI: 0.12-0.35, P < 0.00001). No difference was found ...

In pediatric dentistry, chloral hydrate is habitually selected for sedation of uncooperative children. Although chloral hydrate has been used for decades, various adverse effects are reported and necessity for new alternative drugs has increased. Dexmedetomidine was approved by FDA for sedation at intensive care units (ICU) in 1999. Compared to conventional sedative drugs, dexmedetomidine has n...

Despite lack of paediatric labelling, contributions to the literature on paediatric applications of dexmedetomidine have increased over recent years. Dexmedetomidine possesses many properties that are advantageous for a sedative and anaesthetic; it has been reported to provide sedation that parallels natural sleep, anxiolysis, analgesia, sympatholysis, and an anaesthetic-sparing effect with min...

Propofol and dexmedetomidine are both commonly used anaesthetics. Although they employ two different mechanisms to induce anaesthesia, both compounds influence the hippocampus and the HT22 cell line. HT22 cells are broadly used in neurobiological research. In this study, we assessed the effects of propofol and dexmedetomidine on signalling in HT22 cells. Using the SILAC (stable isotope labellin...

Parturients with uncontrolled hyperthyroidism presenting as urgent cesarean section are at high-risk. A 34-year-old, G4P3 parturient, at 34+5 weeks of gestation, with uncontrolled hyperthyroidism presented for urgent cesarean section. A combined spinal-epidural anesthesia was performed. Intravenous dexmedetomidine, as an adjuvant, was specifically administered during and after the surgery. Appr...
