Use of the oesophageal detector device in children under one year of age.
The efficacy of a modified oesophageal detector device was evaluated in a single-blind study of 20 healthy infants. It was found to be unreliable as a method to discriminate oesophageal from tracheal intubation in this age group.

Accuracy of flexible fiberoptic endoscopy in identifying abnormal endotracheal tube positions.
This study was carried out to investigate the accuracy of a simple, nonmaneuverable, flexible fiberoptic catheter in identifying both normal and abnormal endotracheal tube (ETT) positions. In addition, the utility of flexible fiberoptic endoscopy (FFE) for ETT position determination in inexperienced hands was examined. One adult dog was sedated and instrumented in the esophagus and trachea with identical ETTs. ⋯ There was no difference in performance by investigator training level or endoscopy experience. We conclude that FFE is a rapid and accurate method for determining both normal and abnormal ETT locations. ETT position determination can be confidently performed by health professionals with minimal training.

Endotracheal tube cuff pressure assessment: pitfalls of finger estimation and need for objective measurement.
Estimation of endotracheal (ET) cuff pressure by finger palpation is one of the methods currently used in the clinical setting. We compared the accuracy of this method with instrumental intracuff pressure measurement in tracheal model tests by 20 members of our ICU team. ⋯ We observed differences in terms of sensitivity, specificity, and positive predictive power between different tubes reflecting differences in tube characteristics and interobserver variability. We conclude that precise intracuff pressure measurement is mandatory to prevent complications of over- or underinflation.

Case ReportsSwallowing disorders in patients with prolonged orotracheal intubation or tracheostomy tubes.
Eleven patients were tested for swallowing dysfunction after prolonged orotracheal intubation. Ten had a tracheostomy tube. Mean duration of orotracheal intubation was 19.9 days, mean age 65 yr, and no patient had a concomitant neurologic deficit. ⋯ We concluded that prolonged orotracheal intubation with or without tracheostomy may cause prolonged and severe swallowing dysfunction. The deficits improve with time. The presence of a gag reflex does not confer protection against aspiration of pharyngeal contrast.

Ninety-one laser laryngeal procedures using the apneic technique of anesthesia were performed in 28 patients between 2 months and 64 years of age. Seventy-two procedures (79%) were performed on children and 19 on adults. There were no complications. ⋯ The apneic technique described in this paper provides a laser operative field free of an endotracheal tube, virtually eliminating the danger of a laser fire. It is a relatively safe and effective means of performing laser laryngeal surgery. In addition, the Laser-Flex endotracheal tube appears to be an acceptable alternative to a metallic tape-wrapped endotracheal tube.
