Abstract

The use of point-of-care ultrasound (POCUS) has become increasingly prevalent in medical practice as a non-invasive tool for focused bedside diagnosis. Consequently, some medical schools have begun implementing POCUS training as a standard in their medical school curriculum. The feasability and value of introducing POCUS training at the medical student level to screen for abdominal aortic aneurysms (AAA) should be explored. Given this, the objective of our study was to determine the test characteristics of point-of-care ultrasonography performed by a medical student versus physical examination by vascular surgeons compared to a gold standard reference scan for the detection of AAAs. We conducted a prospective, observer-blinded study recruiting patients from an outpatient vascular surgery clinic. Participants were screened for AAAs by standardized physical examination by a blinded vascular surgeon, followed by a POCUS examination by a blinded medical student. The student underwent prior training by a vascular sonographer and emergency physician on 60 patients (16 were supervised). Ultrasonography was used to visualize and measure the proximal, mid, and distal aortic diameters. The maximal aortic diameter was noted and compared w...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
