Although bedside ultrasonography can accurately distinguish esophageal from tracheal intubation, it is not used to establish the correct depth of endotracheal tube insertion. As indirect sonographic markers of endotracheal tube insertion depth have proven unreliable, a method for visual verification of correct tube depth would be ideal. We describe the use of saline to inflate the endotracheal cuff to confirm correct endotracheal tube depth (at the level of the suprasternal notch) by bedside ultrasonography during resuscitation. This rapid technique holds promise during emergency intubation.

Retrobulbar hemorrhage is a rare complication of blunt ocular trauma. Without prompt intervention, permanent reduction in visual acuity can develop in as little as 90 minutes. We report a novel bedside ultrasound finding of conical deformation of the posterior ocular globe: the “guitar pick” sign. In our elderly patient, the ocular globe shape normalized post–lateral canthotomy and inferior cantholysis. Identifying this sonographic finding may add to the clinical examination when deciding whether to perform decompression.

Summary

The primary indication for emergent ultrasonography of the aorta is to identify an abdominal aortic aneurysm (AAA). AAAs develop slowly and may be asymptomatic or present with life threatening rupture. AAA rupture accounts for more than 10,000 deaths per year in the United States. When ruptured or leaking AAA is suspected, ultrasound has many appealing qualities. Particularly for the hemodynamically unstable patient, bedside ultrasonography offers a prompt, accurate diagnosis. Although ultrasound is an excellent modality for identifying AAA, it is not effective in identifying whether rupture or leaking has occurred. The decision that an AAA is ruptured is typically based on ultrasound findings of the presence of an aneurysm as well the patient's clinical presentation. The presence of an obese body habitus or bowel gas may lead to poor quality ultrasound imaging and make accurate assessment of AAA difficult.
