In today’s post, I will review the diaphragmatic injury practice guidelines published by the Eastern Association for the Surgery of Trauma (EAST). I will follow this up on Friday with an interesting delayed diaphragm injury case. Diaphragm injury is a troublesome one to diagnose. It is essentially an elliptical sheet of muscle that is doubly curved, so it does not lend itself well to diagnosis by axial imaging.

When we think of severe hemorrhage in children, we typically think about trauma. Maybe injuries to the spleen or kidney come to mind. Perhaps thoughts of pelvic injuries or severe head injury dominate our considerations. Of course, we all have a healthy respect for post-tonsillectomy hemorrhage and we like to talk about Damage Control Resuscitation.

Diaphragm injury from blunt trauma is uncommon, occurring in only a few percent of patients after high-energy mechanisms. They usually occur on the left side and are more frequently seen after t-bone type car crashes and in pedestrians struck by a car. Blunt diaphragm injury on the right side is very unusual. Even so, it is more easily detected due to obvious displacement of the liver that can be seen on chest x-ray.

Researchers at the University of California San Diego have created a wearable ultrasound system that can monitor deep tissues, as far as 16.5 cm (6.5 inches) below the surface of the body. Moreover, the team employed a machine learning algorithm to reduce the noise associated with movement, helping to obtain reliable readings while the wearer goes about their day.

However, unlike similar devices that have been developed previously, this capsule can drive around the stomach under the control of a clinician. This allows it to thoroughly navigate and screen the entire area to identify any health issues in the stomach mucosa, such as ulcers or bleeding.

When considering an optimized environment for compassionate patient communication, the chaotic emergency department (ED) probably gives some clinicians pause.

The tiny devices, which are 20 micrometers wide and considerably smaller than the width of a human hair, can move incredibly fast for their size, achieving a speed of 3 millimeters per second. To put this in context, if a microrobot and a cheetah the same size had a race, the microrobot would win comfortably.
