Randomized Controlled Trial Comparative Study
Comparison of two insertion techniques of ProSeal laryngeal mask airway: standard versus 90-degree rotation.
This study compared two insertion techniques of ProSeal laryngeal mask airway. ⋯ The rotational technique is more successful than the standard technique and is associated with less pharyngeal mucosal trauma, as evidenced by a lower incidence of sore throat and mucosal bleeding.

Comparative Study
Use of the Pentax-AWS in 293 patients with difficult airways.
Several case reports have shown that the Pentax-AWS (Hoya Corporation, Tokyo, Japan), a new video laryngoscope, is useful in patients with difficult airways. ⋯ The success rate of tracheal intubation using the Pentax-AWS was high in patients with difficult laryngoscopy with a Macintosh laryngoscope and in patients with predicted difficult intubation.

Intermittent hypoxia, a powerful and unique stimulus, leads to physiologic changes that are distinct from those associated with either single or continuous hypoxic exposure. There is an accumulating body of evidence that the neurocognitive, inflammatory and cardiovascular symptoms that characterize the syndrome of obstructive sleep apnea are linked to the stimulus of intermittent hypoxia. In addition, altered sensitivities to opiates in children with obstructive sleep apnea have been linked to recurrent hypoxia during sleep. Therefore anesthesiologists should have an understanding of this important stimulus.
