Lifesaving pericardiocentesis due to purulent pericarditis with growth of Gram-negative rods in an immune-competent Inuit male

Polymicrobial Gram-negative pericarditis is a rare entity in the immune-competent patient, and purulent pericarditis due to bacteria complicated by tamponade is a life-threatening condition with high mortality rates. A prompt diagnosis and treatment is, as in this case, lifesaving and facilitated by echocardiography but is not the case in rural areas in common. Change in the infectious aetiology indicates broad-spectrum antibiotics. We describe a case of purulent pericarditis causing cardiac tamponade due to haematogenous spread of Escherichia coli (E. coli) and Proteus species in an immune-competent Inuit male treated with pericardiocentesis.
