BACKGROUND: Pyrexia is common after major surgery, and @entity281 is often an important consideration. To investigate the natural history and association with @entity281 , we performed a prospective observational study. METHODS: From November 2000 to January 2001, we studied 219 @entity1 undergoing cardiac surgery screening daily for wound, respiratory, urinary tract, and other infections. Pyrexia was defined as temperature above 37.5 degrees C. RESULTS: Of 219 @entity1 , 7 intraoperative @entity204 occurred and 1 @entity1 was excluded because of @entity884 , leaving 211. The mean age (SD) was 64 (10) years, consisting of 172 male @entity1 (81.5%). The proportion pyrexial on days 1, 2, and 5 was 30.0%, 25.8%, and 10.3%, respectively. More @entity1 undergoing urgent or emergency procedures (17.7% versus 7.8%; P =.03) subsequently developed @entity221 . However, there were no differences in wound @entity281 (3.4% versus 8.3%; P =.13), positive cultures for respiratory (14.7% versus 11.4%; P =.16), urinary tract (5.2% versus 2.0%; P =.09), or other @entity281 (8.6% versus 7.3%; P =.71) in @entity1 experiencing postoperative @entity221 compared with those who did not. CONCLUSIONS: Pyrexia is common after cardiac surgery and resolves in the majority of @entity1 by day 5. Because there is no association between early @entity221 and @entity281 , diagnosis of early @entity86 by @entity221 alone is insufficient and is better established by clinical assessment with microbiological evidence.
