Unplanned post-operative intubation (UPI) may be associated with significant morbidity and/or mortality after surgery. The purpose of this investigation was to determine the incidence and predictors of UPI in elderly patients who underwent general and vascular surgical procedures. ⋯ Although the incidence of UPI in this elderly surgical cohort was low, it was associated with significant morbidity and mortality as well as prolonged hospital length of stay, underscoring the need for accurately identifying modifiable risk factors.

Randomized Controlled Trial Comparative Study
Validation of a model of graded difficulty in Laerdal SimMan: functional comparisons between Macintosh, Truview EVO2, Glidescope Video Laryngoscope and Airtraq.
A randomised, cross-over study was designed to validate a new model of graded difficulty (based on mandibular space reduction) in the Laerdal 'SimMan' mannnequin and to suggest functional comparisons between Macintosh. Glidescope Video Laryngoscope, Truview EVO2 and Airtraq. ⋯ Our study suggests that Glidescope and, to some extent Truview, are functionally similar to Macintosh and suffer from similar limitations in the difficult setting. On the contrary, Airtraq was functionally unique in providing good laryngeal exposure in the difficult setting and without excessive tongue compression.

The end-tidal desflurane concentration required for smooth removal of the laryngeal mask airway (LMA) has not been established. Therefore, we aimed to find the end-tidal desflurane concentration for safe, smooth, and uncomplicated LMA removal. ⋯ The EC95 of end-tidal desflurane for the smooth removal of the LMA is 3.9%. LMA removal in adults receiving desflurane may be possible at approximately 0.7 minimum alveolar concentration.
