Ludwig Lin, MD, speaks with Michael Blaivas, MD, FACEP, FAIUM, about the article, “Guidelines for the appropriate use of bedside general and cardiac ultrasonography by the intensivist in the evaluation of critically ill patients—Part I: general ultrasonography,” published in Critical Care Medicine. Dr. Blaivas serves as a Professor of Medicine at the University of South Carolina School of Medicine, and works clinically in the St. Francis Hospital Emergency Department in Columbus, Georgia. In this article, Dr. Blaivas and coauthors seek to establish evidence-based guidelines for the use of bedside ultrasound by intensivists and specialists in the intensive care unit (ICU) and equivalent care sites for diagnostic and therapeutic purposes for organs of the chest, abdomen, pelvis, neck and extremities.
