ReviewDeliberate practice for achieving and maintaining expertise in anesthesiology.
For the dedicated anesthesiologist, a high level of expertise is needed to deliver good care to patients and to provide excellent service to surgeons, anesthesia colleagues, and others. Expertise helps the anesthesiologist recover from difficult situations and generally makes the practice run more effectively. Expertise also contributes to quality of life through higher self-esteem and long-term career satisfaction. ⋯ Anesthesiology instruction with attending supervision provides all of the necessary components for deliberate practice, and it can be effective in anesthesia. Using deliberate practice in teaching requires organization in selecting training topics, effort in challenging students to excel, and skill in providing feedback. In this article, we discuss how educational programs can implement deliberate practice in anesthesiology training, review resources for instructors, and suggest how anesthesiologists can continue the practice after residency.

Randomized Controlled Trial Comparative StudyThe Effectiveness of Oxygen Delivery and Reliability of Carbon Dioxide Waveforms: A Crossover Comparison of 4 Nasal Cannulae.
Effective O2 delivery and accurate end-tidal CO2 (ETCO2) sampling are essential features of nasal cannulae (NCs) in patients with compromised respiratory status. We studied 4 NC designs: bifurcated nasal prongs (NPs) with O2 delivery and CO2 sensing in both NPs (Hudson), separate O2/CO2 NPs (Salter), and CO2 sensing in NPs with cloud O2 delivery outside the NPs via multi vents (Oridion) and dual vents (Medline). We hypothesized that design differences between NCs would influence O2 delivery and ETCO2 detection. ⋯ NCs provide supplemental inspired O2 concentrations for patients with impaired pulmonary function. Accurate measures of ETCO2 are helpful in assessing respiratory rate and determining whether CO2 retention is occurring from hypoventilation. These findings suggest the NC with separate NPs was the most effective in delivering O2 and the most consistent at providing reliable CO2 waveforms at higher FGFs.
