Review
Curriculum reform for residency training: competence, change, and opportunities for leadership.
Certain pressures stemming from within the medical community and from society in general, such as the need for increased accountability in resident training and restricted resident duty hours, have prompted a re-examination of methods for training physicians. Leaders in medical education in North America and around the world champion competency-based medical education (CBME) as a solution. The Department of Anesthesiology at the University of Ottawa launched Canada's first CBME program for anesthesiology residents on July 1, 2015. In this paper, we discuss the opportunities and challenges associated with CBME and delineate the elements of the new CBME program at the University of Ottawa. ⋯ Canadian anesthesia residency programs will soon transition to CBME in order to promote better transparency, accountability, fairness, fiscal responsibility, and patient safety. Competency-based medical education offers significant potential advantages for healthcare stakeholders.

Randomized Controlled Trial
Intracuff 160 mg alkalinized lidocaine reduces cough upon emergence from N2O-free general anesthesia: a randomized controlled trial.
Chemical and mechanical irritation of the tracheal mucosa influences the incidence of cough at emergence from general anesthesia, potentially leading to significant postoperative complications. This study evaluates the benefits of endotracheal tube (ETT) intracuff alkalinized lidocaine during N2O-free general anesthesia by 1) assessing the in vitro effect of alkalinization on lidocaine diffusion kinetics across the cuff's membrane and 2) evaluating, in a randomized controlled clinical trial, the impact of 160 mg of intracuff alkalinized lidocaine on cough upon emergence from anesthesia for surgery lasting > 120 min. ⋯ The use of 160 mg of intracuff alkalinized lidocaine is associated with a decreased incidence of cough upon emergence from N2O-free general anesthesia > 120 min. This trial was registered at www.clinicaltrials.gov (NCT01774292).

Randomized Controlled Trial
Performing post-tetanic count during rocuronium blockade has limited impact on subsequent twitch height or train-of-four responses.
Waiting five to six minutes before measuring a train-of-four (TOF) after a 50-Hz tetanic stimulation or post-tetanic count (PTC) in order to allow the facilitation of transmission to subside is commonly recommended but is based on limited evidence. The purpose of this study was to measure the TOF responses after PTC in one hand and to compare the responses with those in the contralateral (control) hand. ⋯ A small but clinically insignificant increase in T1 is seen for at least ten minutes after PTC without any detectable change in T4/T1 values. The TOF responses are reliable as early as one minute after PTC.

Comparative Study Observational Study
Comparing success rates of anesthesia providers versus trauma surgeons in their use of palpation to identify the cricothyroid membrane in female subjects: a prospective observational study.
The primary aim of this study was to compare the success rates of anesthesia providers vs trauma surgeons in their use of palpation to identify the cricothyroid membrane (CTM). The secondary aim was to explore whether prior training and experience performing surgical airways affected the success rates for identifying the CTM. ⋯ The success rates for identifying the CTM using palpation were low and not significantly different for anesthesia providers and surgeons, collectively, as well as for the various levels of training. Anesthesiologists' ability to mark the CTM location correctly did not improve with years of experience.

Observational Study
Dosing and efficacy of intranasal dexmedetomidine sedation for pediatric transthoracic echocardiography: a retrospective study.
We designed this retrospective observational study on the use of α2-agonist dexmedetomidine to determine the optimum intranasal dose to achieve sedation for pediatric transthoracic echocardiography and to identify any dose-related adverse effects. ⋯ We found that aerosolized intranasal dexmedetomidine offers satisfactory conditions for TTE in children three months to three years of age with an optimal dose of 2.5-3.0 µg·kg(-1)administered under the supervision of a pediatric cardiac anesthesiologist.
