Rapid recovery is desirable in pediatric neurosurgical patients to obtain an early neurologic assessment. We compared the recovery characteristics of 2 commonly used anesthetic agents, sevoflurane and isoflurane, under bispectral index-guided anesthesia in children undergoing spinal surgery. Eighty children who underwent surgery for occult spinal dysraphism at the lumbar and ...

Background: Laryngeal mask airways (LMA) are commonly used in paediatric anaesthesia. Correct positioning of the LMA determined by adequacy of ventilation does not always indicate optimal anatomical position by either radiographical or fibreoptic assessment. Comparison of fibreoptic views of the laryngeal inlet seen through different sized paediatric LMA's has not ...

BACKGROUND: Flumazenil is an imidazobenzodiazepine that promptly reverses via competitive inhibition the hypnotic/sedative effects of benzodiazepines on gamma-aminobutyric acid receptors. Endogenous benzodiazepine ligands (endozepines) were isolated in urine, cerebrospinal fluid, and breast milk of women who had not received benzodiazepines. The bispectral index (BIS), an electroencephalographically derived parameter widely used ...

Combined sedation with a benzodiazepine and an opiate has been proposed as standard sedation for bronchoscopy. Propofol is a sedative-hypnotic with a rapid onset of action and fast recovery time, but carries the potential risk of respiratory failure. Consecutive patients (n = 200) were randomly allocated to receive either the ...

BACKGROUND: Pain on injection of propofol is a common clinical problem. Flurbiprofen axetil, an injectable prodrug of flurbiprofen, with or without venous occlusion has been reported to reduce this pain. A search of the existing literature did not identify comparative studies of 3 different techniques, including pretreatment with flurbiprofen axetil, ...
Rhee Ka-young - - 2009
BACKGROUND: A lighted stylet is an effective alternative to a direct laryngoscope and has been reported to be particularly useful in patients with difficult airways. A high Mallampati class indicates poor visibility of the oropharyngeal structures. Because a lighted stylet does not require direct oropharyngeal visualization, we hypothesized that the ...

BACKGROUND AND STUDY AIMS: Sedation with the short-acting anesthetic agent propofol has shown several advantages, particularly in interventional endoscopy. So far, however, there are no valid data on the safety of nurse-administered propofol sedation (NAPS) during interventional endoscopy in elderly high-risk patients. PATIENTS AND METHODS: A total of 150 patients ...

General anaesthesia and deep sedation during endarterectomy exclude direct contact with the patient, required for safe performance of the surgery. The aim of the study was to assess sedation with dexmedetomidine and its cardiovascular effects. Sixty-four adult patients, scheduled on internal carotid artery surgery under infiltration analgesia, were randomly divided ...
White Paul F - - 2009
Pregabalin is a gabapentinoid compound, which has been alleged to possess anxiolytic, analgesic, and anticonvulsant properties. We hypothesized that premedication with oral pregabalin would produce dose-related reductions in acute (state) anxiety and increases in sedation (sleepiness) before induction of general anesthesia. A secondary objective was to determine if premedication with ...
