Echocardiograms can often be limited by poor sonographic windows, but using an echo contrast agent can improve visualization of the left ventricle and detect right-to-left intracardiac shunts. Introduction to the various agents, their principles and use.
I have tired of treating my ultrasound exam of a patient as separate from my physical exam. In the emergency department and ICU where I practice, ultrasound is much more than an adjunct, it is an integral part of my evaluation of the patient. The JAMA series on Rational Clinical Exami
Take a look at this really remarkable ultrasound image, not so much for it immediate clinical utility, but for its rarity. A patient presented with numerous self-inflicted cuts all over the body including bilateral extremities, torso, and neck. Arrived profusely bleeding, and clear
An unconventional approach for treatment for ventricular storm may be an ultrasound-guided block of the stellate ganglion which provides sympathetic stimulation of the heart. This may reduce cardiac irritability and facilitate defibrillation.
My preferred method is the anterior-medial approach. Place the patient in the supine position with knee flexed, and foot plantar flexed and resting flat on the bed. An high-frequency linear probe is most useful for identifying the detailed structures. Using a combination of palpati
Globe rupture is more often occult on presentation. The most frequent sites of rupture are not easily visualized, and more superficial injuries may block examination of the posterior segment. Very small sharp foreign bodies can enter the eye through small wounds that are difficult to visualize. Our institution has developed the following protocol for evaluation of clinically non-apparent ruptured globe injuries.
Reverse takotsubo (stress cardiomyopathy) with hyperdynamic apex and complete akinesia of the base (as opposed to the classic apical ballooning).
This ultrasound is from a young pregnant woman presenting with lower abdominal pain without vaginal bleeding. History of two previous unexplained spontaneous abortions and a known large fibroid. The physical exam was unremarkable but bedside transabdominal ultrasound was performed
