Resuscitation of traumatic cardiac arrest is typically considered futile. Recent evidence suggests that traumatic cardiac arrest is survivable. In this article key principles in managing traumatic cardiac arrest are discussed, including the importance of rapidly seeking prognostic information, such as signs of life and point-of-care ultrasonography evidence of cardiac contractility, to inform the decision to proceed with resuscitative efforts. In addition, a rationale for deprioritizing chest compressions, steps to quickly reverse dysfunctional ventilation, techniques for temporary control of hemorrhage, and the importance of blood resuscitation are discussed...

Surgeons are increasingly using ultrasonography (US) in their clinical management of patients. However, US is a very user-dependent imaging modality and proper skills of the US operator are needed to ensure quality in patient care. This thesis explores the validity evidence for assessment of competence in abdominal and head & neck ultrasonography using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale. With the use of Messick's unitary framework of validity, five sources of validity evidence were explored: test content, response processes, inter-nal structure, relations to other variables, and consequences...

A 54-year-old man presented with severe right upper quadrant (RUQ) abdominal pain. He denied any infective symptoms. On clinical examination, he was afebrile and anicteric. His abdomen was soft with tenderness elicited on the RUQ. A point-of-care ultrasound in the emergency department demonstrated a distended gallbladder with a thickened wall and an impacted large gallstone at the neck of the gallbladder. Furthermore, the point-of-care ultrasound also identified a highly reflective echo from the anterior surface of the gallstone and marked posterior acoustic shadowing...

STUDY OBJECTIVE: Cardiac standstill on point-of-care ultrasonography has been widely studied as a marker of prognosis in cardiac arrest. Return of spontaneous circulation has been reported in as few as 0% and as many as 45% of patients with cardiac standstill. When explicitly documented, the definition of cardiac activity in these studies varied from any slight change in echogenicity of the myocardium to any kinetic cardiac activity. We hypothesize that the variability in research definitions of cardiac activity may affect interpretation of video clips of patients in cardiac arrest...
