Abstract

475 pediatric patients with a variety of neurologic conditions were subjected to encephalography, using N₂O as the contrast medium and N₂O-halothane as anesthetic agents. This technic is both safe and effective, as reflected by no mortality and satisfactory roentgenograms. By application of the principles of gas physics, postoperative discomfort has been greatly reduced, resulting in a more comfortable convalescence and earlier discharge.
