The NeutraClear® needleless connector is equally effective against catheter colonization compared to MicroClave®

Area of Science:

• Infectious Diseases
• Medical Devices
• Microbiology

Background:

• Closed-system, neutral-valve connectors are crucial for reducing catheter colonization.
• Comparative analysis of commercially available connectors is needed to evaluate their contamination protection.
• This study compares the in vitro efficacy of NeutraClear® and MicroClave® connectors against contamination.

Purpose of the Study:

• To compare the in vitro efficacy of NeutraClear® and MicroClave® needleless connectors.
• To assess their performance against microbial contamination under simulated clinical conditions.

Main Methods:

• A model using 200 blood culture bottles (BCBs), 100 with NeutraClear® and 100 with MicroClave®.
• Two experimental conditions: standard care and contamination with Staphylococcus aureus.
• BCBs were incubated for 7 days, and positivity rates and time to positivity were analyzed.

Main Results:

• In aseptic conditions, minimal BCB positivity was observed in both groups (1 vs. 2, p=0.55).
• Under contaminated conditions, all BCBs became positive in both NeutraClear® and MicroClave® groups.
• No significant difference in time to positivity was found between the two connectors (p=0.09).

Conclusions:

• NeutraClear® needleless connector demonstrated comparable efficiency to MicroClave®.
• Both connectors were equally effective in preventing in vitro catheter colonization by S. aureus.
• The study suggests similar protection against microbial migration into the catheter hub.
