Ans. is 'a' i.e., Pericardial Effusion o Auenbruger 's sign is an epicardial bulging due to massive pericardial effusion.Auenbrugeer frsieno It represents bulging of the epigastrium that may be seen in case of severe pericardial effusion.o The auenbrugger s sign is seen in large pericardial effusion.o During a large pericardial effusion an epigastric bulge is present,o This represents large pericardial effusion extending subxiphoid.o Compression of this bulge may cause hemodynamic compromise and cardiac tamponade.Signs in pericardial effusion : -Sign PresentationFriedreich's sign-Sudden collapse inthe distended neck veins with diastole suggests pericardial tamponade.Pitres's sign-Anterior bidging of the lower sternum suggests pericardial effusion.Auenbrugger's sign-Protuberance/Bulging of the epigastrium suggests massive pericardial effusion (Sign on inspection).Sansom s sign-Percussible dullness in the left third intercostal space suggests large pericardial effusion.Greene's sign -Lateral displacement of the percussed cardiac border with expiration suggests a large pericardial effusions.Ebstein's sign A large pericardial effusion can blunt the percussible righ cardiomyopathic angle producing dullness along the lower right sternal border.Rotch's sign-Dullness at the right lower sternal border suggests large pericardial effusion.Moschcowitz s sign-In pericardial effusion, the transition on percussion from the lungs in the right heart border is abrupt.Ewart's sign-A large pericardial effusion produces egophony and bronchial breathing at the lower border of the left scapula.Ewart's second sign-A large pericardial effusion makes the first rib seen more prominent along the sternal border.Dressier 's sign-Is dullness to percussion of the lower one half of the sternum.The Dressier sound is aflat sound on percussion the lower half or two third of the sternum.
