RESUMO
From its first use in medicine, ultrasonography has been an excellent non-invasive diagnostic tool. The use of ultrasound increased dramatically especially in the last decade, as it is a painless, safe, and widely accessible, especially with the development of pocket ultrasound machines. In addition, it is crucial in promptly diagnosing unstable patients in emergency settings. Currently, emergency physicians are leaning more towards ultrasound, fellowships and university courses are created around the globe to teach this essential skill. This article highlights the importance of ultrasound in the hands of emergency physicians while presenting a life-threatening diagnosis that could have been easily missed if it wasn't for the use of ultrasound. Cases like these are frequently seen in the emergency departments, and it is when blinded by a tunnel vision, and anchoring bias, that these serious diagnoses can be left undiagnosed. Many individuals in the medical community are against the use of ultrasound by untrained physicians, but it remains highly recommended that emergency physicians get a proper training on the use of this tool for it is of great value in the emergency department.
