Fetal oxygen saturation (FSpo(2)) is an emerging technology for intrapartum fetal monitoring. We monitored FSpo(2) before and after combined spinal-epidural analgesia in 8 laboring women requesting neuraxial analgesia. ⋯ Fetal oxygen saturation at baseline and after analgesia was 53% +/- 9% and 51% +/- 8%, respectively. We observed no significant FHR changes or any fetal bradycardia following combined spinal-epidural analgesia.

A new method of exchange of nasotracheal to orotracheal tube, using the Laryngeal Mask Airway (LMA), in a patient with difficult airway, is described. A 36-year-old woman with Treacher Collins syndrome was scheduled for a malar apatite cutting and a chin-level osteotomy. ⋯ The nasotracheal tube cuff was deflated, and the fiberscope was inserted into the trachea alongside the nasotracheal tube. The nasotracheal tube was removed, and the oral tube was then advanced into the trachea.
