Case Reports
Diagnosis of a left-sided superior vena cava during placement of a pulmonary artery catheter.
We report a case of a left sided superior vena cava (SVC) that was diagnosed during placement of a pulmonary artery (PA) catheter. After entering the left internal jugular, the PA catheter passed into the left side of the heart, through the aortic valve, and into the aorta. ⋯ The embryology and physiology of a left sided SVC is reviewed, including an historical perspective. A discussion of the variants of the syndrome is included, as is a review of aberrant placement of central venous catheters.

To describe a method of the authors' design for estimating gastric volume quantitatively using ultrasound and to evaluate the usefulness of this method in the clinical setting. ⋯ This method would be useful to estimate gastric contents quantitatively, and a CSA of 8.0 cm2 might be a valid indicator of an empty stomach.

To determine whether nitrogen insufflation reduces the laser-induced combustibility of polyvinyl chloride (PVC) endotracheal tube cuffs. ⋯ Nitrogen insufflation decreases CO2 laser-induced PVC endotracheal tube cuff combustibility. However, clinical applications of this technique should be undertaken with caution, as the administration of a hypoxic mixture may be possible.

Case Reports
Nasotracheal intubation in a child with Treacher Collins syndrome using the Bullard intubating laryngoscope.
Tracheal intubation may be difficult or impossible in children with Treacher Collins syndrome. Nasotracheal intubation may be required for appropriate repair of cleft palate in these patients. This report describes the use of the Bullard intubating laryngoscope to facilitate nasotracheal intubation in a child with severe mandibulofacial dysplasia.
