The Fondazione Umberto Veronesi ethics committee recently published a statement concerning the inherent ethical issues of randomized clinical trials (RCTs), mainly focusing on randomization, raising many questions, and suggesting possible solutions. The main concern is that the patients enrolled in a RCT are used to improve medical knowledge, but they cannot be the beneficiaries of the results of the trials in which they are participating. Possible solutions come from a wider use of clinical and administrative databases, and an early termination of trials. ⋯ The assumption and concern that there is a conflict between "scientific" and "ethical" aspects of a clinical trial due to randomization should at least be mitigated, considering that only scientifically sounded studies can be considered ethical. Randomization remains the appropriate approach to ensure the study's internal validity. Different aspects seem to be more important, from the ethical point of view, considering RCT and their publication.

Observational Study
Improvement in GlideScope® Video Laryngoscopy performance over a seven-year period in an academic emergency department.
To evaluate the outcomes in first pass success (FPS) of GlideScope (GVL) intubations over a seven-year period in an academic ED. Data were prospectively collected on all patients intubated in an academic ED with a level 1 trauma center over the seven-year period from July 1, 2007 to June 30, 2014. Following each intubation, the operator completed a standardized data collection form that included information on patient, operator and procedure characteristics. ⋯ By the seventh year of the study, the first pass success with the GVL increased to 92.1% (128/139; 95% CI 86.3-96.0%) and the percentage of patients with CL I/II views was 94.2% (131/139; 95% CI 89.0-97.5%). In the logistic regression model, first pass success improved during the seven-year period (aOR 3.1; 95% CI 1.3-7.1; p = 0.008). Over the seven-year period, there was significant improvement in the first pass success of the GVL, without any change in the Cormack-Lehane view, suggesting that there was improvement in the skill of tube delivery with use of the GVL over time.
