Full description

BACKGROUND A previous study compared vortexing and Maki techniques for the diagnosis of catheter-related bloodstream infection (CRBSI), and concluded that vortexing was not superior to Maki method.

AIM To determine whether the combined use of vortexing and Maki techniques provides profitability versus the Maki technique for the diagnosis of catheter tip colonization (CTC) and CRBSI.

METHODS Observational and prospective study carried out in an Intensive Care Unit. Patients with suspected catheter-related infection (CRI) and with one central venous catheter for at least 7 days were included. The area under the curve (AUC) of the Maki technique, the vortexing technique and the combination of both techniques for the diagnosis of CTC and CRBSI were compared.

Enrollment: 136 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients with suspicion of catheter-related infection (CRI) and with long term CVC (at least 7 days)

Exclusion criteria

• none
