Clinical usefulness of catheter-drawn blood samples and catheter-tip cultures for the diagnosis of catheter-related bloodstream infections in neonates

Abstract

Catheter-drawn blood sampling is an efficient method of diagnosing catheter-related bloodstream infection (CRBSI) in neonates; it has greater sensitivity and accuracy than methods using catheter-tip cultures. No association was detected between catheter-drawn blood sampling and the occurrence of adverse events with central venous catheters.

The Radiographic Changes of Catheter Tip in Different Positions of Arm Infusion Port

“…Ferreira J. et al, thought the infusion PORT was also called PORT, which is a closed infusion system which is implanted subcutaneously and remains in the body for a long time. The infusion port is suitable for patients who need long-term infusion, repeated blood drawing, intravenous nutrition support, and chemotherapy, mostly tumor patients [ 6 ]. Fhrs et al believe that cancer patients need repeated intravenous fluids because of the long treatment cycle, especially during chemotherapy, targeting, immunization, and nutritional support, so that they do not only have to endure the pain of puncture, but frequent punctures can also cause blood vessel occlusion, making treatment of tumor patients even more difficult [ 7 ].…”

Diagnostic and Therapeutic Utility of Positive Intravascular Catheter Tip Cultures

“…In a 2015 letter to Clinical Infectious Diseases , Lance Peterson reiterated the inadequacy and the potential risk of CTC, based on its unreliable and generally poor positive predictive value for catheter-related bloodstream infections ( 10 ). Ferreira et al compared the clinical utility of catheter-drawn blood versus CTC for neonatal catheter-related bloodstream infection cases and found no difference in patient outcomes between the two methods ( 11 ). Thus, although CTC results can contribute to the diagnosis of catheter-associated bacteremia, the differential time to positivity is often available before the CTC results.…”
