Analysis Of Risk Factors Of Central Venous Catheter-related Infections In Pediatric Patients Undergoing Cardiac Surgery

Objective: Central venous catheter (CVC) plays an important role in the infusionand parenteral nutrition during and after cardiac surgery. CVC as a channel connecteddirectly with the heart and blood circulation, poor management can leading to infection isdifficult to control. In this paper, we talked about bacterial distribution of the centralvenous catheter-related infections (CVC-RI) in pediatric patients undergoing cardiacsurgery and risk factors of CVC-RI for infection to reducing the CVC-RI incidence toprovide a reliable reference for clinical scientific management of central venous catheter.Methods: From Jan.2010to Dec.2011, we chose334patients with after cardiac surgeryto culture CVC tip bacterial and identify antimicrobial susceptibility. Results:334casesof CVC were cultured43cases of pathogens. The most common pathogens isAcinetobacter baumannii. With the extension of time to extubation, the CVC-RIdifference in the rate between the groups was statistically significant (P＜0.01). With theextension of the cardiopulmonary bypass transit time difference between CVC-RIincidence was statistically significant (P＜0.01), the incidence of CVC-RI With theextension of the cardiopulmonary bypass transit time obvious increasing trend.Conclusion: CVC as an important source of pathogenic bacteria, we should strengthenaseptic technique, shorten the retention time and reduce the variety of risk factors lead toCVC-RI. We should be timely and reasonable application of antibiotics, in order toreduce the negative consequences brought about by the long-term indwelling CVC.
