A new infant ventilator for normal and high-frequency ventilation: influence of tracheal tube on distal airway pressure during high-frequency ventilation.
A new infant ventilator for both normal and high-frequency ventilation is described. High pressure gas delivered via a jet in the breathing limb of a T-piece, in which there are no valves, drives respiratory fresh gas (RFG), supplied to the tracheal tube from any low pressure source, into the lungs. ⋯ In this open valveless breathing system, desynchronized spontaneous and artificial ventilation occurred quietly without any marked variation in the airway pressures. This preliminary study on a new pneumatic system shows its potential for simplifying and improving infant ventilation.

Limited data are available on the efficacy of a common endotracheal suctioning intervention to prevent postsuctioning decreases in arterial oxygenation (PaO2). This study evaluated the effect on Pao2 of five hyperinflation (tidal volume 1.5 times normal) and hyperoxygenation breaths, administered before and after each of two consecutive endotracheal suctioning passes, with use of a manual resuscitation bag (PMR-2 model). The convenience sample consisted of 32 patients with endotracheal tubes who were observed within 24 hours of coronary artery bypass surgery. ⋯ In addition, a clinical measure of alveolar-capillary gas exchange (PaO2/PAO2 ratio) was found to be a significant predictor of PaO2 after suctioning, accounting for 38% of the variance. The data from this study support the efficacy of administering five hyperinflation and hyperoxygenation breaths, with use of a manual resuscitation bag, before and after endotracheal suctioning in stable patients after coronary artery bypass surgery. Further study is necessary to determine the efficacy of this suctioning intervention in patients with other respiratory problems.

The influence of tube size, cuff inflation, and pharyngeal packing on development of sore throat after nasotracheal intubation was studied. Pharyngeal packing was found to be the most significant factor, followed by tube size and inflation of the cuff.

A simple method for preventing obstruction of the endotracheal tube during palatal surgery.
In this paper we describe a simple method for avoiding the obstruction of the Mallinckrodt R. A. E. (Ring, Adair and Elwin) preformed endotracheal tube which we use during cleft palate surgery, palatal lengthening and pharyngoplasty in patients who have well developed lower incisor teeth.
