Auenbrugger's Sign
Auenbrugger's sign (/ˈaʊənbrʊgər/; German: [ˈaʊənbrʊgər]), also known as percussion sign, is a medical sign used in the diagnosis of pleural effusion. It was first described by the Austrian physician Leopold Auenbrugger in the 18th century.
Etymology
The term "Auenbrugger's sign" is named after Leopold Auenbrugger, who first described the technique of chest percussion in his 1761 book "Inventum Novum". The word "sign" in this context refers to a medical sign, an objective indication of some medical fact or characteristic that may be detected by a physician during a physical examination of a patient.
Description
Auenbrugger's sign is a physical examination technique used to assess the presence of fluid in the pleural cavity. It involves tapping on the chest wall and listening to the sound produced. A dull sound indicates the presence of fluid, while a clear, resonant sound suggests that the pleural space is free of fluid.
