The purpose of this study was to analyze previously reported airway risk factors in the performance of Miller laryngoscopy and orotracheal intubation. ⋯ The Miller blade is highly successful in the performance of direct laryngoscopy for orotracheal intubation. These findings suggest that different sets of airway risk factors affect the process of laryngoscopy and orotracheal intubation.

An intubation difficulty scale (IDS) is the most commonly used tool to pronounce difficult intubation among obese patients in research area. There have not been any studies on assessing the use of IDS. The objectives were to determine the performance of the IDS among obese patients to define difficult tracheal intubation (DI) according to the subjective assessment of the difficulty experienced and to identify their optimal cutoff points. ⋯ The IDS remains a good tool to declare DI among obese patients. It is recommended that a score of 2 or higher is an optimal cutoff point to indicate somewhat DI and a score of 5 or higher is an optimal cutoff point to indicate DI.

Influence of dexmedetomidine on cognitive function in volunteers.
Some outpatient procedures are performed under sedation with dexmedetomidine, although the effect of dexmedetomidine on cognitive function remains unclear. This study investigated the effect of dexmedetomidine on cognitive function in healthy volunteers. ⋯ Dexmedetomidine slightly reduced response speed and consistency, but did not affect response accuracy. Cognitive function was restored to pre-administration values 2 hours after the infusion of dexmedetomidine was discontinued.
