Ultrasound assessment of the lumbar spine to facilitate neuraxial anesthesia has recently received much attention. The transfer of knowledge pertaining to this skill has never been studied. The purpose of this study was to determine the amount of teaching needed to achieve competence in spinal ultrasound. ⋯ Under the study conditions, 20 supervised trials plus teaching sessions were not enough for the participants to achieve competence in different aspects of ultrasound assessment of the lumbar spine. These results may well be considered when planning teaching sessions and workshops in the future.

Routine preoperative electrocardiogram and chest x-ray prior to elective surgery in Alberta, Canada.
A study was undertaken to evaluate the utilization rates of routine preoperative electrocardiogram (ECG) and chest x-ray (CXR) by sex, age, and most frequent surgery type, and to estimate the total cost of these screening tests. ⋯ Routine preoperative testing rates and costs are relatively low in Alberta. It is possible that general evidence widely disseminated over the past number of years regarding unnecessary routines in preoperative testing has had an effect. Further interventions to reduce them would be of little value.
