Comparative Study
Respiratory status of children with epiglottitis with and without an artificial airway.
During a ten-year period, 22 children from our 170 cases of acute epiglottitis had reliable records of arterial blood gas data. The arterial/alveolar (a/A) oxygen tension ratios were calculated, with a value less than 0.75 representing abnormal gas exchange. ⋯ Thirty-three percent of initial chest roentgenograms were abnormal, with the major disorder being atelectasis and/or consolidation. We propose that the radiologic and gas exchange abnormalities result from the common pathophysiologic mechanism of increased lung water.

Synchronized intermittent mandatory insufflation of the endotracheal tube cuff.
Continuous inflation of endotracheal tube cuffs causes tracheal injury in up to 11% of intubated patients. To avoid this complication and its consequences of tracheal and laryngeal stenosis and tracheoesophageal fistula, we designed a simple device which enables intermittent inflation of the cuff during inspiratory periods of mechanical ventilation. ⋯ We have used the device in 25 patients with prolonged intubation. There was no air leak around the tube, no aspiration of gastric content, and no late complications as shown by direct laryngoscopy at 1 week, 1 month, and 3 months after extubation, and by X-ray of the upper airway.
