CONTEXT AND OBJECTIVE We hypothesised that head and neck position could affect the effectiveness of ventilation with the i-gel airway. To test this hypothesis, we investigated the influence of different head and neck positions on oropharyngeal sealing pressures and ventilation scores during ventilation with i-gel. METHODS A single, experienced(More)
PURPOSE The aim of this study was to investigate the influence of mouth opening on oropharyngeal leak pressure, intracuff pressure, and cuff position of the laryngeal mask airway (LMA). PATIENTS AND METHODS Fifteen patients who were scheduled for elective oral surgery were recruited into this study. A single, experienced LMA user inserted the LMA(More)
PURPOSE This study was performed to determine the optimal degree of mouth opening in anesthetized patients requiring laryngeal mask airway (LMA) during oral surgery. PATIENTS AND METHODS A single, experienced LMA user inserted the LMA in 15 patients who were scheduled for elective oral surgery. Oropharyngeal leak pressure, intracuff pressure, and(More)
HIFU therapy is one of epoch-making, low-invasive treatments for prostate cancer. We investigated 71 patients who had undergone HIFU therapy from June 2004 through September 2005. We mainly gave a single spinal injection followed by epidural catheterization with a combined spinal-epidural anesthesia kit. Three patients received general anesthesia because of(More)
We report a case of diplopia during continuous epidural injection presumably caused by catheter migration. A 61-year-old woman underwent shoulder surgery under general anesthesia with cervical epidural anesthesia. The epidural catheter was placed in the C6–C7 epidural space with some difficulty before general anesthesia. The depth of the catheter placed(More)
PURPOSE This study investigated the effects of head-neck extension on abnormalities of laryngeal mask airway (LMA) function resulting from opening the mouth. PATIENTS AND METHODS A single, experienced LMA user inserted the LMA in 15 patients scheduled for elective oral surgery. Oropharyngeal leak pressure and intracuff pressure were sequentially(More)
PURPOSE This study compared the Portex introducer, ivory type (PII) (Portex Tracheal Tube Introducer; SIMS Portex, Hythe, Kent, England), and Cook Airway Exchange Catheter (CAEC) (Cook, Letchworth, Hertfordshire, England) with regard to success rate of and time required for tracheal intubation by use of each device by oral and maxillofacial surgeons on a(More)
A 59-year-old woman with an epiglottic tumor was scheduled for the total removal of the mass by laryngomicrosurgery. The patient had no preoperative respiratory symptoms. During the induction of anesthesia, the mask ventilation was easily accomplished; however, when rigid laryngoscopy was attempted, an epiglottic tumor prevented exposure of the vocal cords.(More)
