Background: Dexmedetomidine, a selective ?2 agonist has shown promising results when used as premedicant. This prospective randomized study evaluated the efficacy of two different premedication regimens in achieving smooth conduct anesthesia and optimum pain relief pediatric cataract surgeries. Methods: 90 ASA I or II children, aged 1-6 years, scheduled for elective surgeries were to receive ei...

BACKGROUND There is growing interest in glutamatergic agents in depression, particularly ketamine, a glutamate N-methyl-d-aspartate (NMDA) receptor antagonist. We aimed to assess the efficacy of ketamine in major depressive episodes. METHOD We searched EMBASE, PsycINFO, CENTRAL, and Medline from 1962 to January 2014 to identify double-blind, randomized controlled trials with allocation concea...

Sixteen captive female red deer were successfully anesthetized to surgically implant a telemetry system. The deer were immobilized with (mean±SD) 1.79±0.29 mg/kg xylazine and 1.79±0.29 mg/kg tiletamine/zolazepam given intramuscularly with a dart gun. Anesthesia was maintained for 69±2 min using a total intravenous protocol with a catheter placed in the jugular vein. Group X received xylazine (0...

Oral sedatives are often required for children who require dental restoration. Most children are able to receive this in the dental office, often using nitrous oxide with minimal sedation to facilitate the procedure. However, there are children who will not cooperate during the examination process or during the actual dental procedure without sedation [1]. This can be due to young age, behavior...

Bidirectional nasal drug delivery is a new administration principle with improved deposition pattern that may increase nasal drug uptake. Twelve healthy subjects were included in this open, non-randomized 3-way crossover study: midazolam (3.4 mg) intravenously (1 mg mL (-1)), or nasally by bidirectional or traditional spray (2 x100 microL of a 17 mg mL(-1) nasal midazolam formulation). The prim...

The effects of lumbar intrathecal (i.t.) and intracerebroventricular (i.c.v.) midazolam on nociception during isoflurane anaesthesia were studied in rats using the tail-flick test. Rats received i.t. midazolam 2 and 4 microg or i.c.v. midazolam 4 and 8 microg during 1.1, 1.2 and 1.3% isoflurane or without isoflurane. Neither i.t. nor i.c.v. midazolam alone at doses studied influenced nociceptiv...

We studied the interaction of azole antimycotics with intravenous (IV) and oral midazolam using a cross-over design in 12 volunteers, who ingested placebo, itraconazole, or fluconazole for 6 days. A 7.5-mg dose of midazolam was ingested on the first day, 0.05 mg/kg was administered IV on the fourth day, and 7.5 mg orally on the sixth day. Itraconazole reduced the clearance of IV midazolam by 69...
