The patency of the airway via each upper airway orifice during general anesthesia.
The patency of the airway via each orifice was examined during general anesthesia in 112 patients by occluding other orifices in order to develop a method in which fiberoptic endotracheal intubation (FEI) and ventilation could be performed via different orifices. Ventilation was well maintained via the mouth in 61 (54.5%), via bilateral nostrils in 87 (77.7%), and via the unilateral right and left nostril in 67 (59.8%) and 73 (65.2%) patients, respectively. With the aid of an artificial airway, ventilation was well maintained via the mouth in 112 (100.0%), via bilateral nostrils in 111 (99.1%), and via the unilateral right and left nostril in 106 (94.6%) and 105 (93.8%) patients, respectively. Based on these findings, we developed a method in which FEI is performed via the nostril, while ventilation is performed with a mask applied over only the mouth.

Case ReportsFoley catheter used as bronchial blocker for one lung ventilation in a patient with tracheostomy--a case report.
Anesthesia with one-lung ventilation is a good anesthetic technique for patients receiving thoracotomy in various underlying diseases. One lung ventilation can be achieved successfully by the application of a double-lumen endotracheal tube through the oral route. ⋯ Bronchial blocker with a Fogarty embolectomy catheter has been used successfully for such situations. Here, we reported the clinical experience in using the Foley catheter as the bronchial blocker in a patient with tracheostomy.

EEG bispectrum predicts movement during thiopental/isoflurane anesthesia.
The objective of our study was to test the efficacy of the bispectral index (BIS) compared with spectral edge frequency (SEF), relative delta power, median frequency, and a combined univariate power spectral derivative in predicting movement to incision during isoflurane/oxygen anesthesia. ⋯ When bispectral analysis of the EEG was used to develop a retrospectively determined index, there was an association of the index with movement. Thus, it may be a useful predictor of whether patients will move in response to skin incision during anesthesia with isoflurane/oxygen.

Randomized Controlled Trial Clinical Trial
The effect of midazolam premedication on implicit memory activation during alfentanil-nitrous oxide anaesthesia.
Eighty-three patients were given midazolam 0.1 mg.kg-1 by intramuscular injection as premedication before general anaesthesia with alfentanil-nitrous oxide. During anaesthesia patients were presented (through headphones) with either statements about common facts of some years ago (group A) (n = 43) or new verbal associations, e.g. names of fictitious, nonfamous people (group B) (n = 40). ⋯ In this study we found no explicit or implicit memory for the auditory information presented during anaesthesia. Midazolam premedication can prevent implicit memory activation during alfentanil-nitrous oxide anaesthesia.
