Elevated postoperative serum procalcitonin is not indicative of bacterial infection in cardiac surgical XXXX .

@entity1 @entity281 @entity295 @entity86
BACKGROUND: Identifying @entity281 early, commencing appropriate empiric antibiotic not only helps gain control early, but also reduces mortality and morbidity. Conventional cultures take about 5 days to identify @entity281 . To identify the @entity281 early biomarker like serum procalcitonin (SPC). AIMS: We studied the correlation of an elevated level of SPC and positive culture in elective adult @entity1 undergoing cardiac surgery. METHODS: This prospective study was conducted from January to December 2013. SPC was checked in @entity1 showing evidence of @entity295 . Simultaneously, relevant culture was also undertaken. Correlation, specificity, and sensitivity of elevated SPC were checked. RESULTS: A total of 819 adult @entity1 were included in the study. 43 of them had signs of @entity281 and SPC levels were checked. Based on the level of SPC criteria, 10 @entity1 were diagnosed as "nil", out of them, 4 had culture-positive @entity281 , 17 were suggested to have "mild @entity281 ," 3 out those had culture positivity. None among the eleven @entity1 suggested to have "moderate @entity281 ," had a positive culture, and one among the five suggested to have a severe @entity281 had a positive culture. The sensitivity was 50% and the specificity 17%. The positive predictive value was 12% and the negative predictive value 60%. CONCLUSIONS: We failed to elicit positive correlation between elevated SPC levels and @entity86 in cardio surgical @entity1 .
