Purpose of ReviewThe purpose of this article is to review the literature relevant to point of care ultrasound (POCUS) with an emphasis on the application of ultrasound in preoperative assessment. It addresses the use of cardiac, lung, gastric, and vascular ultrasonography.Recent FindingsThe use of POCUS as an adjunct to the physical examination is gaining traction as high-quality equipment becomes increasingly portable and dramatically more affordable. While the literature on preoperative ultrasound by anesthesiologists is limited, there is growing evidence that it is not only feasible, but also improves patient morbidity and mortality.SummaryAnesthesiologists frequently encounter patients with signs and symptoms of heart failure, significant cardiac murmurs, hemodynamic instability, unexplained dyspnea, and unknown gastric contents. Studies to date show that POCUS can change management of these patients and improve morbidity without delaying care. Randomized trials are needed to validate these findings. Professional societies in anesthesiology need to define standards for POCUS training, as well as establish mechanisms for certification and maintenance of proficiency.
