If you are a serious about pursuing a career in emergency medicine, I highly recommend taking a quality course in emergency ultrasound techniques. The potential for ultrasound in the ED is vast. All EM residency programs must now provide ultrasound training for their graduates to be board-eligible.
This year, I attended both the Introductory and Advanced emergency ultrasound courses by 3rd Rock Ultrasound. The experience was excellent and by far one of the best emergency medicine CME experiences I have attended to date. My next working day, I was able to put these new skills to work as an extension of my physical examination.
