Efficacy of disinfection procedures to reduce Acinetobacter baumanii bla_OXA-23 contamination rate of needleless connectors: an in-vitro study.

ABSTRACT:

Aim

This study aimed to verify the efficacy of disinfection procedures to reduce Acinetobacter baumannii bla_OXA-23 bacterial load in needleless connectors that had been experimentally contaminated.

Methods

Two-way intermediate extender's hub and needle-free valve were contaminated with Acinetobacter baumannii bla_OXA-23. To disinfect them, the following procedures were carried out: sterile gauze with 70% ethanol, sterile gauze with Incidin®, and 70% isopropyl alcohol single-use cap, with eight times friction for 10 s, followed by 5 s drying time. The statistical tests Kruskal-Wallis and post-hoc Conover were performed using MedCalc®.

Results

A total of 82 experiments were conducted. All tested disinfection procedures were efficacious
