Fever is defined as a core body temperature of >38.3 degrees C or 101 degrees F. About 50% of fevers in the ICU are due to infectious causes. Absence of fever in patients with infection heralds a poor prognosis. Temperatures between 102 degrees F-106 degrees F are more likely to be due to infection. The common infectious causes of fever are pneumonia, urosepsis, line infections and intraabdominal infections. Temperatures <102 degrees F or >106 degrees F are usually due to non-infectious causes like deep venous thrombosis, infusion reactions, aspiration, drug fever and the neuroleptic malignant syndrome. Fever should be distinguished from hyperthermia as antipyretics are ineffective in the latter. Inappropriate use of antibiotics selects resistant bacterial strains, but delay in treating infection could increase mortality. A structured approach is therefore required in order to correctly diagnose and treat fever in critically ill patients.

A case of intravenous precipitation of erythromycin is reported along with the patient history, pathologic findings, and a description of the analytical methods and results. The patient was a 75-year-old woman with a history of myocardial infarction, deep venous thrombosis, and diabetes mellitus who underwent aortic valve replacement. She developed endocarditis and recurrent episodes of urosepsis, with multiple organ failure including severe gastric retention, for which she was treated with erythromycin intravenously. She died because of refractory septic shock. Autopsy revealed aortic valve endocarditis, thrombi in the right femoral vein, arterial (nonfungal) thromboemboli in the celiac trunk, and coarse material in the right femoral vein where the tip of the central venous catheter had been located. Microscopical examination of the coarse material showed that it was birefringent crystalline material. Part of the postmortem material was analyzed in the laboratory of the department of clinical pharmacy and revealed the presence of erythromycin. Erythromycin was detected using Fourier transform infrared spectroscopy. An additional specific color test and thin-layer chromatography confirmed this finding. On the basis of the postmortem findings, patient history, and analytical-toxicologic results, we conclude that erythromycin precipitation can occur in vivo after intravenous administration in patients with impaired blood flow.
