We studied on 70 cases of middle ear anomalies by a standard correspondence analysis method. The external meatus of these cases was open. We classified these 70 cases into the following four groups: type D: disruption between the long process of the incus and the movable oval window (54.3%), type F: immovable oval window with no disruption between the long(More)
BACKGROUND There is controversy regarding which fluid management regimen provides the best postoperative outcome. Interstitial fluid accumulation may adversely affect postoperative outcome, but the effect of surgical duration on fluid balance is unknown. In this study, we used a mathematical model to describe fluid distribution. METHODS Previously(More)
Malformations of the ossicles in 52 ears of 48 patients were analyzed on the basis of surgical findings. The external meatus of each of these ears was patent. The long process of the incus and the stapes are frequently involved in this series of observations. There are distinct groups of ossicular anomalies, in each of which patients show similar degrees of(More)
Despite the importance of the inhibition of catabolic response to surgery, the effects of different anesthetic techniques on the catabolic response in surgical patients are controversial. This study compared the endocrine-metabolic responses and protein catabolism during gastrectomy in patients who received either sevoflurane or propofol anesthesia with(More)
A 37-year-old woman with bronchial tumor was scheduled for the removal of the mass with fiberoptic bronchoscope. Intubating laryngeal mask airway (ILMA) was used for fiberoptic surgery. Through a size 3 ILMA, a 5.9 mm outer diameter fiberoptic bronchoscope reached the trachea easily. The operation was successfully performed with assisted ventilation.(More)
To construct optical networks more economically, it is necessary to make effective use of existing ducts and spaces for the installation of optical fiber cables. In recent years, several studies on ultra-highdensity optical fiber cable with pliable ribbons have been reported, some of them including 4-fiber pliable ribbons already put to practical use as(More)
BACKGROUND The Japanese Society of Anesthesiologists (JSA) started the annual survey of the critical incidents related to anesthesia in 1992. The certified anesthesia-training hospitals, which are more than 700 in Japan, send the questionnaire results to JSA every year. This is a nationwide large-scale survey, in which more than 150 million cases are(More)
