The electroencephalograms (EEG) of 55 children under isoflurane anesthesia were studied to elucidate any change in pattern with age. The children ranged from 1 month to 14 years of age were divided into six age groups. The standard minimum alveolar concentration (MAC) was determined in each group. ⋯ At 1.5 MAC, the incidences of burst suppression in the groups of 6 months to 6 years of age were significantly less than in groups older or younger than that age (P<0.05). Except for infants less than 6 months of age, the mean values of maximum amplitude at 1.0 MAC were two to three times of those in adults. Children 3-6 years of age showed the highest value of 427.0±83.5 μV.

Effect of the lithotomy position on spinal anesthesia with hyperbaric tetracaine.
This study was performed to determine the effects of lithotomy position on the spread of analgesia and hemodynamics following spinal anesthesia with 0.5% hyperbaric tetracaine. Thirty patients who underwent hysterectomy due to myoma uteri were studied. ⋯ There were no significant differences between the groups in mean arterial pressure, heart rate, cardiac output, and in the cephalad spread of analgesia. The lithotomy position had no effect on the spread of analgesia or anesthetic course of spinal anesthesia with hyperbaric tetracaine.

Textbook of anesthesia on electronic media: trial version as a free software.
The author has compiled a textbook of anesthesia on a floppy diskette and has made it available as free software. It is called "KSAP", which stands for "Knowledge Source for Anesthesia Practice". He aims to create a new form of textbook that is appropriate for current technology. ⋯ The entire book consists of approximately 500 text files, all of which were written by this author. All that is required to use this textbook is an MS-DOS computer and software which reads ASCII text files. Individual files are all simple text files.

Effects of combined intravenous nicardipine and diltiazem administration on the circulatory response to laryngoscopy and tracheal intubation.
To evaluate the effect of combined intravenous administration of the calcium antagonists, nicardipine and diltiazem, on the circulatory responses to tracheal intubation, the mean arterial pressure (MAP) and rate pressure product (RPP) in response to laryngoscopy following tracheal intubation were compared in patients receiving saline placebo or nicardipine 10 μg·kg-1 and diltiazem 0.1 mg·kg-1 60 s before the initiation of laryngoscopy. Each group was comprised of ten patients undergoing elective surgery. The patients receiving saline showed a significant increase in MAP and RPP associated with tracheal intubation. However, these increases were significantly attenuated (P<0.05) in the patients to whom nicardipine and diltiazem were administered concurrently.
