Role of serum C-reactive protein and interleukin-6 as a predictor of intra-abdominal and surgical site infections after elective abdominal surgery.

Abstract

Infections after surgeries considerably increase patients' hospital stay, thereby prolonging patients' early return to productive life. At the same time, the cost of hospitalization also increases. Therefore, if objective tests can predict infections before it actually happens, then more preventive measures in the form of upgrading antibiotics can be taken which might prevent patients from developing serious infections and thereby reduce morbidity and mortality of surgery. It was a prospective cross sectional study to assess the efficacy of acute phase reactants C-reactive protein (CRP) and interleukin 6 (IL 6) in predicting infections in patients undergoing routine general surgical operations. A total of 74 patients were included in the study. Laparoscopic surgical procedures were not included in the study to maintain uniformity in the procedures. Data so collected were analyzed by using SPSS version 22. A total of 27 patients developed wound infections postoperatively. The mean rise in the levels of CRP and IL 6 was higher in those patients who developed postoperative wound infections. The positive predictive value and negative predictive value was found to be better with IL 6 than with CRP. It may be concluded that a serial estimation of CRP and IL 6 postoperatively can predict infections and may be utilized routinely in general surgical practice.
