    Abstract:
    The danger of cardiac tamponade occurring when pericarditis is accompanied by pericardial effusion, as opposed merely to the presence of a friction rub without effusion, has been unclear. Forty patients on hemodialysis were studied by physical examination, chest x-ray film, and echocardiography for evidence of pericarditis and pericardial effusion. Only two patients developed a friction rub during the study and were placed on regional heparin. Ten of 11 patients who were positive on echocardiogram for pericardial effusion had unremarkable physical examinations. These 11 patients had cardiomegaly as noted on chest x-ray examination. Eighteen of 25 patients without effusion also had cardiomegaly on chest x-ray film. No patient remaining on systemic heparin and having a pericardial effusion developed cardiovascular complications during hemodialysis. This study suggests that while many patients on longterm hemodialysis have pericardial effusion undiagnosed on the basis of physical examination, but noted on echocardiogram, special precautions to prevent tamponade during hemodialysis are not necessary. Also, posterior-anterior chest x-ray film showing a normal-sized heart will usually exclude significant pericardial effusion.
