Observational Study
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.

In the axillary fossa, the musculocutaneous nerve (MC) is generally distant from the axillary artery and from the other brachial plexus nerves. In that way, MC requires a specific block. ⋯ Abduction of the shoulder significantly reduced the distance between the MC and the axillary artery. This change in the location of the MC is probably due to the moving of the nerve because of muscle rearrangements and the ability to achieve better proximity of the probe in the axillary fossae.

Mentorship of residents has been extensively studied within many academic specialties, but not anesthesia. The purpose of this study is to determine the prevalence of formal mentorship programs among anesthesia residency programs accredited by the Accreditation Council for Graduate Medical Education in the United States by surveying residency directors. The secondary goals of the study are to describe the programs that exist and identify areas that residency directors think should be the focus of mentoring. ⋯ Anesthesiology is currently underrepresented in the trainee mentoring literature. There is significant support for mentorship during resident training; however, the low rates of training for faculty and minimal evaluation by residents and faculty raise the question as to the efficacy of the existing programs. There is a need for more investigation of anesthesia residents' goals and perceptions of mentorship, and a more detailed evaluation of existing mentorship programs to determine the ideal structure of a mentoring program.
