This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to intraoperative and postoperative complications, and time to discharge from hospital for knee arthroscopies in outpatients. We studied 70 ASA I patients scheduled for elective outpatient knee arthroscopy. The patients were randomly allocated into two groups(More)
BACKGROUND The alpha agonist dexmedetomidine, a sedative and analgesic, reduces heart rate and blood pressure dose-dependently. We investigated whether it also has the ability to attenuate airway and circulatory reflexes during emergence from anaesthesia. METHODS Sixty ASA I-III patients received a standard anaesthetic. Five minutes before the end of(More)
BACKGROUND Children undergoing cardiac catheterization usually need general anesthesia or deep sedation. OBJECTIVE This study was performed to compare the effects of propofol/dexmedetomidine and propofol/ketamine combinations on recovery time and hemodynamic parameters in pediatric patients undergoing transcatheter atrial septal defect (ASD) closure.

Extracorporeal shock wave lithotripsy (ESWL) requires sedation in pediatric patients. Dexmedetomidine is a relatively new agent used for sedation. The aim of this randomized prospective study was to compare the effects of dexmedetomidine–ketamine and midazolam–ketamine combinations on the recovery time, hemodynamic and respiratory variables, and side(More)
BACKGROUND AND OBJECTIVES The aim of this study was to investigate the effects of inhalational anaesthesia using low and high gas flow rates of nitrous oxide and desflurane on mucociliary clearance and pulmonary function. METHODS Fifty adult patients of the American Society of Anesthesiologists physical status I-II, aged between 18 and 70 years, were(More)
BACKGROUND Myoclonic movements are common problems during induction of anesthesia with etomidate. The aim of this study was to compare the effect of pretreatment with dexmedetomidine (0.5 microg/kg) and thiopental (1 mg/kg) on the incidence of etomidate-induced myoclonus and postoperative pain. MATERIALS AND METHODS A prospective double-blind study was(More)
OBJECTIVE Brachial plexus block offers several advantages when creating vascular access for hemodialysis. However, no controlled studies have directly evaluated arteriovenous fistula (AVF) blood flow in patients anesthetized by this method. We compared the effects of ultrasound-guided, infraclavicular brachial plexus block and local infiltration anesthesia(More)
This study was designed to compare the effects of premedication with dexmedetomidine and midazolam on post-electroconvulsive therapy (ECT) agitation (which patients had experienced previously and had been resistant to treatment). In addition, we aimed to evaluate the duration of convulsion, the propofol requirement, the recovery time, and patients’(More)
BACKGROUND AND OBJECTIVE The aim of this study was to determine the duration of onset and regression time of sensory and motor blocks, the quality of anaesthesia and postoperative analgesia by the addition of dexmedetomidine to local anaesthetic solution in intravenous regional anaesthesia (IVRA). METHODS Forty patients scheduled for elective hand surgery(More)
OBJECTIVE We aimed to investigate the effects of dexmedetomidine premedication before intravenous infusion of ketamine in agitated children undergoing strabismus surgery. SUBJECTS AND METHODS We enrolled 60 agitated pediatric patients, aged 4.5-11 years. The patients were randomly allocated to one of two anesthesia regimens. Group D patients were(More)
