Last week, we learned the basics on how to perform an ocular ultrasound and what a normal eye looks like on ultrasound. This week, we cover 5 eye pathologies that are easy to diagnose with use of ultrasound.
Anatomic landmarks followed by a "blind" stick is currently the standard practice for performing bedside lumbar punctures, but with increasing use and ease of ultrasound, could we one day see lumbar punctures follow in the footsteps of central line placement?
You evaluate a patient complaining of acute onset of dyspnea with hypotension and hypoxia. You immediately consider the diagnosis of acute massive pulmonary embolism, but despite your best efforts can't get good cardiac windows on bedside ultrasound. Should you administer thrombolytics? Heparin? Send the shocky patient for a CT? Today Dr. Simpkins goes through the steps to perform 2-point compression ultrasound of the lower extremity to evaluate for DVT, an easy and rapid bedside test that may allow for indrect but more rapid diagnosis of acute, massive pulmonary embolism.
Pericardiocentesis is a rarely performed, but potentially life-saving procedure. Commerical models are prohibitively expensive, but students and residents (and critical care fellows) still need to learn the mechanics, ideally with an ultrasound compatibile model. This week's post gives a step by step guide towards making a cheap, easy to fabricate phantom based on this fantastic paper published in the Journal of Emergency Medicne 2012: https://www.ncbi.nlm.nih.gov/pubmed/21925818
