Here is a link to the video of POCUS Case 5 – Small Bowel Obstruction from the always outstanding Emergency Medicine Cases:
POCUS Cases is an original EM Cases video series led by Dr. Robert Simard, an Emergency Physician at North York General Hospital and Sunnybrook Health Sciences Centre in Toronto. Rob always wished he had x-ray vision…but since he possesses no special powers…using Point-of-Care Ultrasound (POCUS) is the next closest thing. He completed a POCUS fellowship at NOSM and teaches POCUS nationally and internationally. He is the creator POCUS Cases, an original EM cases screencast that provides POCUS clinical pearls in an engaging and fun way that will help you provide stellar care to your patients.
In this POCUS Cases 5 – Small Bowel Obstruction, Dr. Simard explains the limitations of x-rays for small bowel obstruction, the three signs of small bowel obstruction on POCUS including the “keyboard sign”, the most important literature on the topic and the limitations of using POCUS for the diagnosis of small bowel obstruction.
Keep your eyes open for a new POCUS Cases each month!
And here is a link to a list of all of the great POCUS cases so far.
